Abstract
The invention relates to a disposable sterilization perspective sheath for an endoscope. The sheath comprises an isolation casing pipe matched with the endoscope. One end of the isolation casing pipe is provided with a lens to form a sealed end while the other end of the same is of a horn mouth shape. The sheath can be used for preventing the hard endoscope from entering human organ tissues directly and ensures that the hard endoscope enters the human organ tissues by being sleeved in the disposable sterilization safe casing pipe, which is completely sterilized, so that the organ tissues are isolated from the endoscope and the goal of examining by the endoscope safely is achieved. The sheath is beneficial to avoidance of embolism or other complications caused by cross-infection generated when the endoscope is in contact with the human organ tissues directly and the sterilization is incomplete, so that the recovery of the patient is facilitated. The disposable sterilization perspective sheath for the endoscope has the advantages of use convenience, one-off replacement property, better operability, better comfortableness, better sterilization reliability, and capabilities of saving the sterilization time, effectively increasing the examining efficiency of the endoscope, prolonging the service life of the endoscope and effectively reducing dangers of iatrogenic cross-infection.
Description
Technical field
The invention belongs to the medical protection device that loculus health check-ups such as can be used for department of otorhinolaryngology is looked into, be specifically related to be used for insulation blocking primary sterilization perspective sheath in the rigid endoscope.
Background technology
The advantage of splanchnoscopy and operation is very outstanding, and it can go deep into the patient's body lumen diagnosis, has intuitive, reliability, invasive, has now become a clinical irreplaceable diagnosis and treatment technology.Yet in splanchnoscopy and operation, the doctor can touch blood, body fluid inevitably when pincers are got biological tissue etc.Endoscope is in a single day contaminated, and the patient symptom occurs from occurring to of infection and needs a period of time behind microscopy, and this causes many hospitals to underestimate the seriousness that infects.Endoscope's cost height can not disposablely use again.Therefore, require very high to its sterilization.But there are a lot of difficulties again in actual disinfecting action, and is only still not exclusively reliable by conscientious careful immersion and flushing etc.In addition, the macromolecular material of endoscope can not high temperature resistant, high pressure, causes the sterilization means limited.
Summary of the invention
In order to solve the problem that has the incomplete possible cross infection that brings of endoscope sterilization in operation process now, a kind of primary sterilization perspective sheath that is used for endoscope that can avoid scope and human body directly to contact provided by the invention.
Concrete technical solution is as follows:
The primary sterilization perspective sheath that is used for endoscope comprises the disrance sleeve that cooperates with endoscope, and an end of described disrance sleeve is provided with lens, forms blind end, and the other end is a bell mouth shape.
The wall thickness of described disrance sleeve is 2 millimeters, and the wall thickness of horn mouth and adjacent is 3 millimeters; Described lens thickness is 1 millimeter.
The material of described disrance sleeve is natural rubber or thermoplastic elastic material (TPE); Described lens material is optical glass or polymethyl methacrylate (PMMA).
Being matched in clearance between the lens end of described disrance sleeve internal diameter and the endoscope, is interference fit between its flared end and the endoscope.
The present invention is based on is inserted in endoscope in the disrance sleeve, well rigid endoscope is fixed by the interference fit that the disrance sleeve structure produces, and fixing back scioptics are observed pathological changes body region in the human body.
The present invention's useful technique effect compared with prior art is as follows:
1, use this sheath can avoid rigid endoscope is directly entered the human organ tissue, but rigid endoscope is inserted in to enter the human organ tissue in the primary sterilization safety sleeve pipe of sterilizing fully, thereby organ-tissue and endoscope are isolated, reach the purpose of endoscope's safety inspection.Avoided causing thromboembolism or other complication, also be convenient to patient's recovery because endoscope directly contacts with human tissue organ owing to sterilization not exclusively forms cross infection;
2, easy to use, sterilization time is saved in disposable replacing, effectively improves endoscopy efficient, and the reliability of better operability, comfortableness and sterilization is arranged, and can improve the mirror body life time, effectively reduces the danger of medical cross infection.
Description of drawings
Fig. 1 is a jacket structure sketch map of the present invention.
Fig. 2 is user mode figure of the present invention.
Serial number name among the last figure: disrance sleeve 1, lens 2, rigid endoscope 3.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described by embodiment.
Embodiment 1:
Referring to Fig. 1, the primary sterilization perspective sheath that is used for endoscope comprises and the disrance sleeve 1 of endoscope's interference fit that one end of disrance sleeve 1 is installed with lens 2, forms blind end, and the effect of lens 2 is that the transitive graph picture is to rigid endoscope port; The other end is a bell mouth shape.The wall thickness of disrance sleeve 1 is 2 millimeters, and the wall thickness of horn mouth and adjacent is 3 millimeters; Lens thickness is 1 millimeter.The material of disrance sleeve 1 is a natural rubber; Lens 2 materials are BK-7 optical glass.Being matched in clearance between the lens end of disrance sleeve 1 internal diameter and the rigid endoscope 3, is interference fit between the flared end of disrance sleeve 1 internal diameter and the rigid endoscope 3, and effect is to prevent relative slip in order to fixing rigid endoscope.The length of disrance sleeve is between 100-180mm, and is consistent with the rigid endoscope guide rod length that is complementary.
During use, rigid endoscope is slowly slipped into disrance sleeve 1, when the flared end of endoscope's rear end port and disrance sleeve 1 was coincide, rigid endoscope 3 front ends just arrived at lens 2 inwall places.Disrance sleeve 2 adopts general natural rubber or the lower soft plastic of chlorinty, and its toughness and adsorptivity are relatively good, and the structure of employing interference fit is fixed on endoscope 3 at the horn mouth place of disrance sleeve 1.
See through the lens 2 transitive graph pictures of disrance sleeve 1 end during operation, lens 2 are extraordinary glass of permeability or lucite, can effectively reduce brightness decay.In the cavity checking process, the inwall situation of cavity, the camera collection that can proper scioptics 2 passes in the rigid endoscope 3 comes out, and is presented on the monitor really.
The material of disrance sleeve 1 is thermoplastic elastic material (TPE); Lens 2 materials are polymethyl methacrylate (PMMA).
Other is with embodiment 1.
