Description

VR-based patient preoperative psychological construction system and method

Technical Field

The invention relates to the technical field of intelligent psychological construction in medical treatment, in particular to a VR-based system and a VR-based method for pre-operative psychological construction of patients.

Background

In the course of disease treatment, especially Western medicine, the effect of surgery is often applied directly to the affected part to eliminate the pain. However, for most patients, whether the surgery is of a size or not complex, a strong psychological stimulus. Psychological studies indicate that patients are subjected to surgery, often with anxiety, fear, and even fear, and the above psychological changes can lead to increased secretion of epinephrine and norepinephrine through the action of the sympathetic nervous system, causing adverse physiological changes such as increased blood pressure, increased heart rate, and the like. Meanwhile, a large number of clinical observations and researches prove that the negative psychological state can cause negative effects on preoperative, intraoperative and postoperative conditions: such as cold limbs, tremble, narrow consciousness area, sensitivity to environment and instruments, and even pathological psychological activities; the blood pressure fluctuation and the blood loss are large in the operation, and the operation effect is affected; the wound healing after operation is slow, the infection rate after operation is high, the body function recovery is slow, and complications are easy to cause. Therefore, the psychological construction before operation has extremely important significance.

Currently, psychological guidance is mainly applied to patients in clinical practice by means of preoperative talking and psychological counseling. Preoperative talking is generally performed by a doctor in charge, and the doctor pays the illness state in detail to the patient and family members, clarifies the importance and necessity of the operation, introduces the method mode and possible and happening of the operation, listens to the opinion and the requirement of the patient, and solves the problems presented by the patient, especially the related problems of operation safety. On the basis of conventional preoperative conversations, special medical staff are arranged for psychological dispersion, and the medical staff generally have considerable psychological knowledge or psychological consultation practitioner qualification or belong to special psychological support departments of patients.

However, effective preoperative talking and psychological grooming is costly in terms of labor and time. Secondly, the effect of preoperative talking and psychological dispersion is highly dependent on the professional level, experience and communication art of medical staff, and is difficult to be homogenous. In addition, preoperative talking and psychological distraction cannot maximally solve the anxiety and fear of the patient to the operation. The fear of the patient to the operation is derived from the unknown fear of the operation environment and the operation passing through to a great extent, and the patient cannot visit the operation room in advance or the operation passing through to solve the fear caused by the unknown problem due to the aseptic management requirement and the ethical requirement of the operation room.

Detailed Description

In order to describe the technical content, the constructional features, the achieved objects and effects of the present invention in detail, the following description is made in connection with the embodiments and the accompanying drawings.

In this embodiment, a pre-operation psychological construction method for a patient based on VR is disclosed instead of manually performing automated pre-operation psychological construction on the patient, as shown in fig. 1 and 2, and the method includes the following steps:

s1: playing virtual images simulating real scenes for patients through the VR device 11 (such as VR glasses), wherein the virtual images comprise disease-related information images and operation-related information images;

s2: in the process of playing the virtual image, applying a touch sense of the patient caused by the simulated operation process to the corresponding part of the patient body in cooperation with the content of the current virtual image;

s3: monitoring vital sign parameters of a patient in real time;

s4: and after the virtual image is played, comprehensively evaluating the current psychological state of the patient by combining the monitored vital sign parameters.

Psychological dispersion and reinforcement can be carried out in a targeted manner on links which affect the current patient with relatively large psychological fluctuation according to the evaluated psychological states. Preferably, the operation related information image includes one or more of an operation condition introduction image, a post-operation condition introduction image, a simulated real operation room image, a simulated post-operation observation room image, and an operation actual process image.

The specific operation flow of the preoperative psychological construction method is as follows:

firstly, a simulated operating room for implementing the pre-operation mental construction method is provided, wherein a main control system 10, a VR device 11, a somatosensory device 12, a monitoring device 13 and an evaluation device 14 which are in communication connection with the main control system 10 are arranged in the operating room, and in addition, an operating table with adjustable lying posture can be arranged in the simulated operating room for patients to use. The somatosensory device 12 is used for applying touch sense to the patient in coordination with the virtual image output by the VR device 11, the monitoring device 13 is used for monitoring vital sign parameters of the patient, and the evaluation device 14 is used for evaluating the current psychological state of the patient according to the feedback of the monitoring device 13. The main control system 10 pre-stores disease-related information images introduced by various diseases and operation-related information images of various operations.

After the patient enters the simulated operating room, VR device 11 is taken on, at which point host system 10 has entered virtual images into VR device 11 corresponding to the patient's condition and surgery. Before playing the virtual image, the VR device 11 may further confirm patient information, for example, after the VR device 11 is turned on, personal information such as a name, a sex, an age, a hospital number, etc. of the patient is broadcasted first, then the patient waits for confirmation, after the patient confirms, the VR device 11 starts to introduce the disease first, that is, plays an image of the disease related information corresponding to the disease suffered by the patient, and because the patient wears the VR device 11, the patient has a face-to-face communication feeling with the introducer in the playing process of the virtual image, and the site feeling is stronger. After the introduction of the disease-related information image is completed, the operation-related information image is started to be played.

The playing process of the operation related information image comprises the following steps:

the first stage is to introduce images of the surgical situation, and at this stage, the principle and process of the surgery to be performed by the patient are introduced in a 3D animation mode.

The second stage is to introduce images of the postoperative condition, and in this stage, the postoperative condition, notes and the like are introduced in a face-to-face explanation mode of a real person.

The third stage is to simulate a real operating room image, in which the patient is presented with the same operating environment as the operating room in which the operation is to be performed, and the patient can also adjust the viewing angle by turning the head of the VR device 11.

The fourth stage is the actual operation process image of the operation, in which the operation process is simulated in a 3D animation mode, and in addition, the simulation of the operation process of the whole process is performed for the local anesthesia operation, and the simulation is only performed to the anesthesia stage for the general anesthesia operation; to increase the real experience of the patient, at this stage, the somatosensory device 12 cooperates with the simulated operation process to perform synchronous actions, for example, when the simulated liver tumor ablation operation process is performed in a local anesthesia state, the somatosensory device 12 locally generates micro heat in the right upper abdominal region of the patient to simulate the experience of the patient in operation; for the benign tumor of mammary gland, the Maimotong operation can generate weak pain stimulus to an operation area and simulate the slight pain after local anesthesia in the operation; for the childbirth pain experience of non-gestational women, paroxysmal pain stimulus is generated to the lower abdomen and pelvic region, and the maximum intensity is 7 grades. Preferably, the somatosensory device 12 in this embodiment is a somatosensory garment through which a sensation of heat and/or pain can be imparted to the body surface of the patient.

Furthermore, an odor releasing device 15 may be further disposed in the operation simulation room, where the odor releasing device 15 is configured to release odor corresponding to the operation site for the patient in cooperation with the virtual image, for example, to release alcohol odor synchronously when the simulated patient enters the operation room; synchronous release of iodophor odor during simulated skin disinfection; and when the local anesthesia operation is simulated to perform electrocoagulation, the burnt smell is synchronously released. In addition, a plurality of sounds can be arranged in the operation simulation room to simulate the equipment sounds in the operation process.

The fifth stage is to simulate the image of the postoperative viewing room, and in this stage, the image is highly restored to the postoperative viewing room and details, and is consistent with the real environment of the hospital, so as to simulate the environment observed after the patient is awake in operation.

In the playing process of the virtual image, particularly the operation-related information image, the monitoring device 13 collects the vital sign parameters of the patient in real time, where the vital sign parameters in the embodiment include one or more of pupil size, heart rate and blood pressure. Correspondingly, a heart rate monitor and a blood pressure monitor are preset in the simulated operating room, and meanwhile, an eye movement tracking sensor is configured on the VR device 11. When the patient is currently too stressed, fear, by the acquired vital sign parameters, the operation of the VR device 11 may be suspended and the patient prompted whether to continue in case of an accident.

After the virtual image is played, the evaluation device 14 forms an evaluation report by reading the feedback data of the monitoring device 13 to evaluate whether the current psychological state of the patient is suitable for operation, if not, psychological dispersion and strengthening training are performed on the scene with larger psychological fluctuation of the patient, and the psychological construction method is performed again.

Further, the virtual image output by the VR device 11 may also interact with the patient in a preset manner and content to improve the participation and real experience of the patient. Specifically, the virtual image played by the VR device 11 is preset with a problem and a corresponding solution that the patient may possibly present, and the VR device 11 may read the voice of the patient through the audio decoder and match the corresponding problem and the solution by capturing keywords in the voice; in addition, the virtual image can also directly give out the possible problem of the patient to select the patient, and output corresponding solutions aiming at the selection of the patient.

Further, in order to evaluate the psychological construction scheme most suitable for the patient, for each scene, the VR device 11 may output multiple virtual images with different arrangements corresponding to the scene, and evaluate each virtual image separately to obtain the optimal virtual image. For example, for operating room and observation room scenes, there are pre-stored multiple scenes with different wall colors, different light configurations and different space sizes. By evaluating the influence of different scenes on the psychological state of the patient, the scene most suitable for the operation of the patient can be found, so that improvement of the relevant scene of the real operation is facilitated.

Furthermore, in order to facilitate the medical staff to comprehensively control the progress of the whole psychological construction method, a first monitoring display screen and a second monitoring display screen which are in communication connection with the main control system 10 can be further arranged; the first monitoring display screen is used for displaying the virtual image output by the VR device 11; the second monitoring display screen is used for displaying vital sign parameters of the current patient. The medical staff can monitor the virtual image currently seen by the patient in real time through the first monitoring display screen, and monitor the current body reaction of the patient in real time through the second monitoring display screen.

The foregoing description of the preferred embodiments of the present invention is not intended to limit the scope of the claims, which follow, as defined in the claims.
