Description

Nasal skull base tumor postoperative nursing device

Technical Field

The invention relates to the technical field of nasal nursing instruments, in particular to a postoperative nursing device for nasal cranial base tumors.

Background

In malignant tumors of nasal cavity and nasal sinuses, the cancer is more than sarcoma, and clinically, squamous cell carcinoma is the first place, accounting for about 70% -80%, and is better developed in maxillary sinuses. Adenocarcinoma and adenoid cystic carcinoma occur in the ethmoid sinus. Sarcoma accounts for 10% -20% of malignant tumors of nose and sinuses, and is better in nasal cavity and maxillary sinus, but rarely in other sinuses. Sarcoma is the most malignant lymphoma, more than 60%. Malignant tumors of nasal cavity and nasal sinuses have the following common characteristics: (1) most of them are primary. (2) The anatomical site of the paranasal sinuses is more hidden, where tumors occur. The early symptoms are few, and the chronic inflammation is often accompanied, so that the attention is difficult to be paid, and the early diagnosis is difficult to be confirmed. (3) The nasal cavity, nasal sinuses, orbit and cranium are adjacent to each other, and the malignant tumors occurring in the above parts can invade adjacent tissues in the late stage, so that it is sometimes difficult to determine their primary sites.

The nasal and cranial bottom tumor is mainly treated by a surgical excision method at present, and after surgery, a patient may have pharyngeal reflex weakened or disappeared, and can have pharyngeal swallowing difficulty, cough and physical sputum excretion difficulty, and the patient needs to be turned over on time, then the back of the patient is knocked from bottom to top, and sputum and aerosol inhalation are carried out at any time, so that respiratory tract obstruction and pneumonia are prevented. At present, the patient is overturned and the back is knocked mainly by the manual work, medical personnel are difficult to overturn the patient alone, and sputum suction operation can not be carried out simultaneously when the patient is knocked, so that the patient is inconvenient to use.

after a patient wakes up, medical staff needs to turn over the patient and back-percuss the patient at intervals to help the patient to remove sputum in the body, firstly, a rocker 25 is rotated in the forward direction, the rocker 25 drives a worm 24 to rotate clockwise, the worm 24 drives a worm wheel 23 to rotate clockwise, the worm wheel 23 drives a connecting gear 22 to rotate clockwise through a pin shaft, the connecting gear 22 drives a right cylindrical gear 21 to rotate anticlockwise, the right cylindrical gear 21 drives a left cylindrical gear 21 to rotate clockwise, the two cylindrical gears 21 respectively drive swing rods 9 on the corresponding sides to swing upwards, and the swing rods 9 drive square rods 6 to slide upwards through inserting columns 7 in a kidney-shaped groove 10;

when the square rod 6 slides upwards along the square tube 5, the rear end of the back plate 3 is driven to swing upwards, the front end of the back plate 3 pulls the support plate 2 to slide backwards, the included angle between the back plate 3 and the support plate 2 is gradually reduced, meanwhile, the back plate 3 starts to drive the body of a patient to turn forwards, the guardrail 35 on the support plate 2 can effectively prevent the patient from falling from the bed body 1 in the turnover process, when the back plate 3 and the support plate 2 are mutually vertical, the posture of the body of the patient is changed from horizontal to right lateral, at the moment, the rocker 25 stops rotating, and as the worm wheel 23 and the worm 24 have self-locking performance, the back plate 3 is kept at the current position;

starting a motor 32, driving a rotating shaft 28 to rotate clockwise by the motor 32 through two second gears 33, driving two first gears 29 to rotate clockwise by the rotating shaft 28, at the moment, engaging the first gears 29 with gear teeth on the lower side of the annular rack 12, driving the annular rack 12 to move leftward by the first gears 29, driving the rectangular frame 11 to move leftward by the annular rack 12, driving the T-shaped block to slide leftward in the sliding cylinder by the rectangular frame 11, driving the positioning column 31 to move leftward along the upper surface of the waist-shaped block 30 by the annular rack 12, driving the connecting plate 13 to move leftward by the annular rack 12, driving the rotating wheel 20 to move leftward by the connecting plate 13 through the sliding rod 17, and driving the rotating wheel 20 to be located in the zigzag-shaped sliding groove 19 at the moment, so that the rotating wheel 20 can drive the sliding rod 17 to reciprocate back and forth when moving leftward, and under the action of the spring and the baffle, driving the two vertical rods 15 to alternately slide upward and downward through the triangular blocks 18 by the sliding rod 17;

the vertical rod 15 drives the bowl-shaped plate 16 to intermittently extend out of the through groove 14 and tap the back of the patient, the vertical rod 15 moves leftwards along with the connecting plate 13 while sliding upwards and downwards, so the bowl-shaped plate 16 taps the back of the patient from right to left, medical staff can suck sputum and atomize the patient at the moment, when the positioning column 31 moves to the left end of the waist-shaped block 30, the first gear 29 is positioned at the right end of the annular rack 12, the first gear 29 drives the annular rack 12 to slide downwards in the rectangular frame 11, the annular rack 12 drives the positioning column 31 to move downwards and contact with the lower surface of the waist-shaped block 30, meanwhile, the annular rack 12 drives the connecting plate 13 to move downwards, the connecting plate 13 drives the rotating wheel 20 to move downwards through the sliding rod 17, and the rotating wheel 20 leaves the sliding groove 19;

the first gear 29 is gradually engaged with the gear teeth on the upper side of the annular rack 12, then the first gear 29 drives the annular rack 12 to move rightwards, the annular rack 12 drives the rectangular frame 11 to slide rightwards, the two annular racks 12 drive the connecting plate 13 to move rightwards, because the rotating wheel 20 leaves the sliding chute 19, the sliding rod 17 does not move forwards and backwards when moving rightwards along with the connecting plate 13, the back knocking is stopped until the positioning column 31 moves to the right end of the waist-shaped block 30 along with the annular rack 12, the first gear 29 is gradually engaged with the gear teeth on the upper side of the annular rack 12, at the moment, the rotating wheel 20 enters the sliding chute 19, and the bowl-shaped plate 16 restarts to knock the back of the patient from right to left;

after the nursing is finished, the motor 32 is turned off, then the rocker 25 is rotated reversely, so that the backboard 3 swings downwards to the horizontal position, and the backboard 3 drives the body posture of the patient to change from lateral lying to horizontal lying.

Therefore, the postoperative nursing device for the nasal skull base tumor can effectively solve the problems that medical workers cannot turn over the postoperative patient alone and are inconvenient to synchronously carry out back knocking and sputum suction on the patient, is simple in structure and operation and convenient to use, and improves nursing efficiency of the medical workers.
