Description
Technical Field
The utility model relates to a device for preventing air leakage during painless enteroscopy.
Background
In the enteroscopy process, a doctor can inflate the intestinal cavity in the operation process to expand the intestinal tract, so that the enteroscope can smoothly enter and is convenient to observe. However, when the painless enteroscope is used, the patient has loose muscles all over the body after anesthesia, the anal sphincter of part of the patient is more seriously loosened, a large amount of gas overflows from the anus when the patient is inflated, the air leakage phenomenon occurs, the operation of a doctor is influenced, and the painless enteroscope is particularly obvious when the patient is subjected to special operations such as low-position rectal polyp or sigmoid colon polyp, and submucosal excision and the like. At present, under the condition, only a mode of stopping painless anesthesia is usually adopted to ensure that the enteroscopy can be successfully completed, but the pain of a patient is increased.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an air leakage prevention device for enteroscopy prevents air leakage in painless enteroscopy.
In order to solve the technical problem, the technical scheme of the utility model is to adopt an air leakage prevention device for enteroscopy, which comprises a catheter, wherein the outside of the catheter is provided with a front annular clamping air bag and a rear annular clamping air bag; the two clamping air bags are communicated through an annular air bag sleeve; the clamping air bag is higher than the air bag sleeve; an annular closed air bag is arranged in the catheter; an elastic sleeve is arranged at the opening at the far end of the catheter, and the opening of the sleeve is connected with the opening of the catheter; and the air inflation and deflation pipe is respectively connected with the clamping air bag and the sealing air bag.
As an improvement, the sleeve is in a taper sleeve shape, the large end of the sleeve is connected with the guide pipe, and the small end of the sleeve is free. The sleeve is made of elastic rubber, and after the enteroscope cannula penetrates through the sleeve, the sleeve can be attached to the surface of the sleeve, so that the sleeve has a sealing effect.
As a further improvement, the diameter of the small end of the sleeve is smaller than that of the enteroscope cannula.
As another further improvement, the catheter silicone tube. The silicone tube has certain support performance and cannot be too hard.
As a refinement, the catheter has a clamping balloon located proximally at a higher elevation than the clamping balloon located distally. Because the clamping air bag at the far end is positioned in the rectum, the height of the clamping air bag is not easy to be overlarge, and the rectum is prevented from being damaged by overinflation.
As a modification, the outer annular surface of the clamping airbag is arc-shaped. The outer cambered surface is combined with the inner wall of the rectum more tightly, so that the air tightness is enhanced.
As an improvement, the two clamping air bags are connected with the air bag sleeve through cambered surfaces. And the mask is more attached to the anus, so that air leakage is avoided.
The utility model discloses an useful part lies in: the air leakage preventing device with the structure has the advantages that the two clamping air bags are matched with each other to clamp the whole device on the anus of a detected person, and an additional device is not needed for fixing. Meanwhile, the clamping air bag positioned in the rectum fills the rectum to avoid air leakage, and the air bag sleeve is positioned at the anus and used for filling a gap between the anus and the catheter. The sleeve and the sealing air bag are used for sealing a gap between the enteroscope intubation tube and the guide tube, and gas is prevented from leaking from the gap.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figure are: 1 intubation tube, 2 conduit tubes, 3 clamping air bag, 4 air bag sleeve, 5 closed air bag, 6 sleeve tubes and 7 inflation and deflation tube.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in fig. 1, the utility model comprises a catheter 2, wherein a front annular clamping air bag 3 and a rear annular clamping air bag 3 are arranged outside the catheter 2; the two clamping air bags 3 are communicated through an annular air bag sleeve 4; the clamping air bag 3 is higher than the air bag sleeve 4; and the clamping balloon 3 at the proximal end of the catheter 2 is higher than the clamping balloon 3 at the distal end. The outer circumferential surface of the clamping airbag 3 is arc-shaped. The two clamping air bags 3 are connected with the air bag sleeve 4 through cambered surfaces. An annular closed air sac 5 is arranged inside the catheter 2; an opening at the far end of the catheter 2 is provided with an elastic sleeve 6, and an opening of the sleeve 6 is connected with an opening of the catheter 2; the sleeve 6 is in the shape of a taper sleeve, the big end of which is connected with the guide pipe 2 and the small end of which is free. The diameter of the small end of the sleeve 6 is smaller than that of the enteroscope cannula 1. And the air inflation and deflation pipe 7 is respectively connected with the clamping air bag 3 and the sealing air bag 4.
When in use, the clamping air bag 3 and the closed air bag 5 are deflated. The distal end of the catheter 2 is inserted into the anus of the subject so that the distal clamping balloon 3 is located in the rectum. The clamping air bags 3 are inflated by the inflation and deflation pipes 7, so that the two clamping air bags 3 are expanded to clamp the anus, and the whole device is fixed at the anus of the examined person. An inflation tube for inflating the intestinal tract of the examined person is inserted into the anus through the inner cavity of the catheter 2 and penetrates through the sleeve 6. And after the inflation is finished, the inflation tube is drawn out. Since the free end of the sleeve 6 is small in opening and flexible, the opening will be closed under the action of the air pressure, so that even after the inflation tube is pulled out, too much air will not escape. And then the enteroscope is inserted into the intestinal tract through the inner cavity of the catheter 2, and the sealing air bag 5 is inflated, so that the sealing air bag 5 fills the gap between the enteroscope cannula 1 and the catheter 2. Meanwhile, the free end of the sleeve 6 is tightly attached to the outer wall of the cannula 1, and the double sealing effect is achieved. In order to facilitate the movement of the enteroscope, vaseline needs to be coated on the cannula 1 for lubrication, so that the excessive friction between the cannula and the closed air bag 5 is avoided. Meanwhile, the clamping air bag 3 positioned in the rectum fills the rectum to avoid air leakage, and the air bag sleeve 4 is positioned at the anus and used for filling a gap between the anus and the catheter 2 and preventing air from leaking from the outside of the catheter 2.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
