Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a rectal inflation leak detection device. Background Technology
[0002] After rectal cancer surgery and recanalization of the intestinal anastomosis, surgeons often need to check the integrity of the intestinal anastomosis. Due to the limited operating space in the pelvic cavity and the irregularity of the tissue anastomosis, it is impossible to visually see whether there are potential small defects or leaks. The usual examination method is to clamp the anastomosis above the abdominal cavity with laparoscopic intestinal forceps under laparoscopic monitoring, fill the pelvic cavity with water to submerge the anastomosis site, and then insert a rubber tube through the anus. Use a 50ml syringe to inflate the intestinal tract to create a local closed space at the anastomosis site. If air bubbles are observed emerging under laparoscopy, it indicates that the anastomosis is not sufficient and the anastomosis needs to be reinforced.
[0003] The existing rectal inflator leak detection devices, in actual operation, have a rubber tube inserted through the anus without a syringe interface. The syringe often leaks air during the inflation process, requiring multiple inflations, resulting in poor effectiveness. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a rectal inflation leak detection device, which aims to improve the problem that gas leaks out between the tubing and the syringe during actual operation of the rectal inflation leak detection device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rectal inflation leak detection device, comprising a rigid tube body, a first connector fixedly connected to the bottom of the rigid tube body, a flexible tube body fixedly connected to the bottom of the first connector, a deflation valve fixedly connected to the bottom of the flexible tube body, a one-way valve fixedly connected to the bottom of the deflation valve, an inflation ball fixedly connected to the bottom of the one-way valve, an inflation monitoring instrument provided at the bottom of the inflation ball, and an anti-detachment component provided at the bottom of the rigid tube body.
[0006] Preferably, the anti-detachment component includes a silicone head, the inner wall of the silicone head is threadedly connected to the outer surface of the first connector, a second connector is fixedly connected to the bottom of the silicone head, a connecting ring is provided at the bottom of the silicone head, a limit member is fixedly connected to the bottom of the outer surface of the second connector, and a third connector is provided on the outer surface of the second connector.
[0007] Preferably, a connecting rod is fixedly connected to the top of the third connector.
[0008] Preferably, the top of the connecting rod is fixedly connected to the bottom of the connecting ring.
[0009] Preferably, the connecting ring fits tightly against the second connector and the silicone head.
[0010] Preferably, a connecting pipe is fixedly connected to the bottom of the hose body, and a pressure gauge is fixedly connected to the bottom of the connecting pipe.
[0011] Preferably, a one-way valve is fixedly connected between the inflatable ball and the inflation monitoring instrument.
[0012] Preferably, a flexible tube head is fixedly connected to the top of the rigid tube.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, a rigid tube is fixedly connected to the top of the flexible tube and an inflatable ball is fixedly connected to the bottom. One-way valves are fixedly connected to both the bottom and top of the inflatable ball. By squeezing the inflatable ball, gas is sequentially passed through the inflatable ball, the flexible tube, and the rigid tube and introduced into the human body. This solves the problem that gas leaks between the tubing and the syringe in the actual operation of the rectal inflation leak detection device.
[0015] 2. In this utility model, due to the shape of the rigid tube itself, it is not easy to fall out after being inserted into the human body. The first connector is fixedly connected to the bottom of the rigid tube, and the silicone head connected to the outer wall of the first connector is rotated to the appropriate position. Then, by pushing the third connector, the connecting ring is pushed upward, which opens the silicone head and blocks it outside the human body to prevent air from flowing out. This solves the problem that the rubber tube is inserted into the anus and there is no fixing device between it and the anal sphincter, so gas can easily leak out along the gap between the anus and the tube, resulting in poor detection effect.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a rectal inflation leak detection device, including a rigid tube 1, a first connector 8 fixedly connected to the bottom of the rigid tube 1, a flexible tube 2 fixedly connected to the bottom of the first connector 8, a deflation valve 3 fixedly connected to the bottom of the flexible tube 2, a one-way valve 4 fixedly connected to the bottom of the deflation valve 3, an inflation ball 5 fixedly connected to the bottom of the one-way valve 4, an inflation monitor 10 provided at the bottom of the inflation ball 5, and an anti-detachment component provided at the bottom of the rigid tube 1.
[0023] Specifically, a rigid tube 1 is fixedly connected to the top of the flexible tube 2, and an inflatable ball 5 is fixedly connected to the bottom. One-way valves 4 are fixedly connected to both the bottom and top of the inflatable ball 5. Another one-way valve 4 is installed between the flexible tube 2 and the top one-way valve 4 for releasing air after inspection. An inflation monitor 10 is installed at the bottom of the bottom one-way valve 4 to observe the amount of gas input during inspection. During inspection, the gas is introduced into the human body through the inflatable ball 5, the flexible tube 2, and the rigid tube 1 by squeezing the inflatable ball 5. Due to the presence of the one-way valve 4, the gas is only delivered into the human body, which solves the problem of gas leaking from between the tubing and the syringe in the actual operation of the rectal inflation leak detection device.
[0024] Reference Figure 3 The anti-detachment component includes a silicone head 11, the inner wall of the silicone head 11 is threadedly connected to the outer surface of the first connector 8, the bottom of the silicone head 11 is fixedly connected to a second connector 12, the bottom of the silicone head 11 is provided with a connecting ring 13, the bottom of the outer surface of the second connector 12 is fixedly connected to a limiting member 16, and the outer surface of the second connector 12 is provided with a third connector 15.
[0025] Specifically, due to the shape of the rigid tube 1 itself, it is not easy to fall out after being inserted into the human body. The first connector 8 is fixedly connected to the bottom of the rigid tube 1, and the silicone head 11, which is threaded to the outer wall of the first connector 8, moves up and down by rotation. After moving to the appropriate position, the connecting ring 13 is pushed upward by pushing the third connector 15. The connecting ring 13 opens the silicone head 11 and blocks it outside the human body to prevent air from flowing out. This solves the problem that the rubber tube is inserted into the anus and there is no fixing device between it and the anal sphincter, so gas can easily leak out along the gap between the anus and the tube, resulting in poor detection effect.
[0026] Reference Figure 3The third connector 15 has a connecting rod 14 fixedly connected to its top.
[0027] Specifically, since the connecting rod 14 is fixedly connected to the top of the third connector 15, the connecting rod 14 is moved by pushing the third connector 15.
[0028] Reference Figure 3 The top of the connecting rod 14 is fixedly connected to the bottom of the connecting ring 13.
[0029] Specifically, the connecting ring 13 is fixedly connected to the top of the connecting rod 14, so the connecting ring 13 can be moved by pushing the third connecting piece 15.
[0030] Reference Figure 3 The connecting ring 13 fits tightly against the second connecting piece 12 and the silicone head 11.
[0031] Specifically, the inner diameter of the connecting ring 13 is tightly attached to the second connector 12, and by moving the connecting ring 13, the silicone head 11 is stretched and relaxed.
[0032] Reference Figure 1 A connecting pipe 6 is fixedly connected to the bottom of the hose body 2, and a pressure gauge 7 is fixedly connected to the bottom of the connecting pipe 6.
[0033] Specifically, by fixing a connecting tube 6 below the hose body 2, and fixing a pressure gauge 7 to the bottom of the connecting tube 6, the pressure inside the human body is monitored to prevent excessive pressure from causing damage to the human body.
[0034] Reference Figure 2 A one-way valve 4 is fixedly connected between the inflatable ball 5 and the inflation monitoring instrument 10.
[0035] Specifically, the one-way valves 4 at the top and bottom of the inflatable ball 5 ensure that gas flows into the human body only from the outside.
[0036] Referring to the figure, a flexible tube head 9 is fixedly connected to the top of the rigid tube body 1.
[0037] Specifically, the flexible tube head 9, which is set at the top of the rigid tube 1, can prevent injury to the human body when the rigid tube 1 is inserted into the human body.
[0038] Working principle: During the examination, lubricant is applied to the flexible tube head 9 and then inserted into the human body. Due to the shape of the rigid tube body 1, it is not easy for the rigid tube body 1 to fall out of the body. Then, the silicone head 11 is rotated to move it up and down to the appropriate position. Then, by pushing the third connector 15, the connecting ring 13 is pushed upward to open the silicone head 11, so that there is no gas leakage at the connection between the tube body and the human body. Then, the inflation ball 5 is squeezed to inflate the human body. Due to the one-way valve 4 at the top and bottom of the inflation ball 5, the gas is only introduced into the human body from the bottom of the inflation ball 5. Medical staff observe the amount of gas introduced from the inflation monitor 10 at the bottom of the inflation ball 5. The internal air pressure is observed by the connecting tube 6 and pressure gauge 7 fixed at the bottom of the flexible tube body 2. After the examination, the gas in the human body is discharged through the vent valve 3 at the top of the inflation ball 5.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
