Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an intraoperative intestinal irrigation and drainage device. Background Art

[0002] Patients with severe intestinal obstruction require surgical treatment, which involves direct intestinal irrigation. This involves disconnecting the colon at one point, squeezing the intestine while irrigating, and slowly draining feces from the disconnected area to relieve the obstruction. Traditionally, there have been no dedicated intraoperative intestinal irrigation and drainage procedures. This presents a high risk of fecal contamination of the operating table, and post-operative cleanup is difficult and odor-prone. While some intestinal irrigation and drainage devices are now available on the market, these devices can only simply collect feces and are unable to completely drain the intestinal tract. Utility Model Content

[0003] The purpose of the utility model is to provide an intraoperative intestinal irrigation and drainage device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The utility model provides an intraoperative intestinal irrigation and drainage device, comprising:

[0006] The drainage tube is a soft component, one end of which is provided with an insertion head;

[0007] A collecting container is detachably connected to the other end of the drainage tube, and the collecting container is provided with an exhaust head;

[0008] The air extraction component includes a pressing airbag, which is provided with an air inlet and an air outlet. A first one-way valve is connected between the air inlet and the air extraction head.

[0009] The beneficial effects of the utility model are:

[0010] During use, one end of the drainage tube is inserted into the broken part of the colon through the insertion head, and the other end of the drainage tube is connected to the collection container. During intestinal irrigation, feces and irrigation water flow into the collection container along the insertion head and the drainage tube in turn. At the same time, the gas in the collection container is extracted by pressing the pressing airbag back and forth to form a negative pressure in the collection container, which has a suction effect on feces and irrigation water, so that the cleaning materials in the intestine are discharged. When the collection container collects a preset amount, the old collection container is removed and the new collection container is installed. The first one-way valve located at the air inlet of the pressing airbag is used to realize the outward flow of the gas inside the collection container, and block the gas in the pressing airbag from flowing inward, so that the pressing airbag only evacuates the collection container.

[0011] As a further improvement of the above technical solution, the collection container is provided with a first quick connector, and the drainage tube is provided with a second quick connector that is matched and detachably connected to the first quick connector. This solution realizes quick connection and quick disconnection of the collection container and the drainage tube through the matching and detachable connection of the first quick connector and the second quick connector. The collection container can be replaced without operating the connection part between the drainage tube and the colon, thereby improving the efficiency of irrigation.

[0012] As a further improvement of the above technical solution, a first air pipe is connected between the air inlet and the air extraction head, the first one-way valve is installed in the first air pipe, the air outlet is connected to a second air pipe, and the end of the second air pipe away from the air outlet is connected to an exhaust head, and the exhaust head is detachably connected to the first quick connector.

[0013] When the collection container collects to the preset capacity and is removed from the drainage tube, the exhaust head can be connected to the first quick connector to seal the first quick connector. At this time, the collection container and the pressing airbag are connected to form a whole for unified recycling processing, and there is no need to set up other sealing parts to seal the first quick connector; in the normal irrigation process, the first quick connector is connected to the second quick connector to achieve communication between the drainage tube and the collection container, and the exhaust head will exhaust air outwards.

[0014] As a further improvement of the above technical solution, the second air pipe is provided with a second one-way valve.

[0015] The second one-way valve in this solution can prevent external air from entering the pressing airbag. When the pressing airbag is pressurized and reset, the pressing airbag only evacuates the collection container. When the pressing airbag is pressed, the gas in the pressing airbag can pass through the second one-way valve and be discharged out along the second air pipe.

[0016] As a further improvement of the above technical solution, the inner peripheral wall of the first quick connector is provided with an internal thread, and the outer peripheral walls of the second quick connector and the exhaust head are both provided with external threads that cooperate with the internal thread.

[0017] Threaded connections are used between the first quick connector and the second quick connector, as well as between the second quick connector and the exhaust head, to improve the sealing of the connection, avoid air leakage or liquid leakage, and facilitate disassembly and assembly.

[0018] As a further improvement of the above technical solution, a plurality of elastic clips are evenly distributed in an annular shape on the outer periphery of the insertion head. The elastic clips extend axially along the insertion head. One end of the elastic clip close to the drainage tube is connected to the outer periphery of the insertion head.

[0019] During installation and use, the insertion head is inserted into the rectal port. In order to prevent the insertion head from falling off during the irrigation process, this solution provides an elastic clip to fix the insertion head. The specific method of use is as follows: after the insertion head is inserted into the rectal port, the elastic clip is located on the outer peripheral side of the rectal port. Through the elastic characteristics of the elastic clip, the elastic clip and the outer peripheral wall of the insertion head clamp the rectal port, thereby fixing the insertion head. When the insertion head needs to be removed, it is only necessary to bend the elastic clip outward to loosen the elastic clip.

[0020] As a further improvement of the above technical solution, the insertion head is a tapered tube structure, the elastic clip is inclined along the outer peripheral conical surface of the insertion head, and a clamping gap is provided between the elastic clip and the outer peripheral conical surface of the insertion head.

[0021] The insertion head in this solution adopts a conical tube structure, which is convenient for insertion into the port of the rectum, and the clamping gap formed between the elastic clip and the outer conical surface of the insertion head can effectively protect the rectum and prevent it from being crushed. The width of the clamping gap is smaller than the thickness of the rectum in its normal state.

[0022] As a further improvement of the above technical solution, a step is provided on the outer periphery of the insertion head near one end of the drainage tube, the elastic clip is connected to the step, and a soft cushion is provided on the inner side of the elastic clip.

[0023] The elastic clip of the present invention is in contact with the rectum through a soft cushion, thereby protecting the rectum, and a step is provided in the present invention to fix the elastic clip.

[0024] As a further improvement of the above technical solution, the elastic clip is connected to the outer edge of the step, so that the width of the clamping gap is gradually reduced from one end of the insertion head close to the drainage tube toward the other end, so that the elastic clip has a clamping elastic force at the end away from the drainage tube.

[0025] As a further improvement of the above technical solution, the end of the elastic clip away from the drainage tube is blunted, so as to avoid the end of the elastic clip from bruising the rectum when the insertion head is inserted into the fracture of the rectum.

[0034] Reference Figures 1 to 3 The utility model is provided with the following embodiments of the intraoperative intestinal irrigation and drainage device:

[0035] The intraoperative intestinal irrigation and drainage device of this embodiment includes a drainage tube 100, a collection container 200 and an air extraction component.

[0036] The drainage tube 100 is a soft component. The drainage tube 100 of this embodiment is made of soft plastic material. The drainage tube 100 is configured as a hose for easy use, and the direction of the drainage tube 100 can be adjusted arbitrarily.

[0037] The two ends of the drainage tube 100 of this embodiment are divided into an insertion end and a connecting end. The insertion end is provided with an insertion head 110. When in use, the insertion head 110 is used to be inserted into the fracture of the intestine, and the connecting end is connected to the collection container 200. During intestinal irrigation, feces and irrigation water flow into the collection container 200 along the insertion head 110 and the drainage tube 100 in sequence.

[0038] The insertion head 110 of this embodiment is also made of a plastic material with a certain hardness.

[0039] When in use, the insertion head 110 is inserted into the port of the rectum. In order to prevent the insertion head 110 from falling off during the irrigation process, Figure 2 As shown, in this embodiment, a plurality of elastic clips 130 are provided on the outer peripheral side of the insertion head 110. The plurality of elastic clips 130 are arranged in a ring-shaped manner. The elastic clips 130 are strip-shaped. The elastic clips 130 are extended axially along the insertion head 110. One end of the elastic clip 130 close to the drainage tube 100 is connected to the outer periphery of the insertion head 110, and the other end of the elastic clip 130 is suspended or in contact with the outer peripheral wall of the insertion head 110. The other end of the elastic clip 130 of this embodiment is suspended on the outer peripheral wall of the insertion head 110.

[0040] The specific insertion operation method is as follows: after the insertion head 110 is inserted into the rectal port, the elastic clip 130 is located on the outer peripheral side of the rectal port. Through the elastic characteristics of the elastic clip 130, the elastic clip 130 and the outer peripheral wall of the insertion head 110 clamp the rectal port, thereby fixing the insertion head 110. When the insertion head 110 needs to be removed, it is only necessary to bend the elastic clip 130 outward to loosen the elastic clip 130.

[0041] Furthermore, the insertion head 110 of this embodiment adopts a conical tube structure, the end of the insertion head 110 connected to the drainage tube 100 is the large head end, and the end away from the drainage tube 100 is the small head end. The elastic clip 130 is arranged at an angle along the outer conical surface of the insertion head 110. In this embodiment, a clamping gap 131 is provided between the elastic clip 130 and the outer conical surface of the insertion head 110. The insertion head 110 adopts a conical tube structure, which is convenient for insertion into the port of the rectum, and the clamping gap 131 formed between the elastic clip 130 and the outer conical surface of the insertion head 110 can effectively protect the rectum and prevent the rectum from being crushed, wherein the width of the clamping gap 131 is smaller than the thickness of the rectum in a normal state.

[0042] like Figure 2 As shown, the insertion head 110 of this embodiment is provided with a step 140 on the outer periphery of one end near the drainage tube 100, and the elastic clip 130 is connected to the step 140, and the elastic clip 130 is connected to the outer edge of the step 140, so that the width of the clamping gap 131 is gradually reduced from the end of the insertion head 110 close to the drainage tube 100 toward the other end, so that the elastic clip 130 has a clamping elastic force at the end away from the drainage tube 100.

[0043] A soft pad 132 is provided on the inner side of the elastic clip 130 , and the elastic clip 130 contacts the rectum through the soft pad 132 to protect the rectum.

[0044] In this embodiment, the end of the elastic clip 130 away from the drainage tube 100 is passivated to prevent the end of the elastic clip 130 from bruising the rectum when the insertion head 110 is inserted into the fracture of the rectum.

[0045] The collection container 200 can be a collection tank or a collection bag. The collection container 200 of this embodiment is detachably connected to the drainage tube 100. When the collection container 200 collects a preset amount, the old collection container 200 is removed and a new collection container 200 is installed.

[0046] The collection container 200 of this embodiment is provided with a first quick connector 220, and the connecting end of the drainage tube 100 is provided with a second quick connector 120. The second quick connector 120 is matched and detachably connected to the first quick connector 220. This embodiment realizes the quick connection and quick disconnection of the collection container 200 and the drainage tube 100 through the matching and detachable connection of the first quick connector 220 and the second quick connector 120. The collection container 200 can be replaced without operating the connection part between the drainage tube 100 and the colon, thereby improving the efficiency of irrigation.

[0047] The second quick connector 120 and the first quick connector 220 can be connected by an interference fit. In this embodiment, a threaded connection is adopted. In this embodiment, an internal thread is provided on the inner peripheral wall of the first quick connector 220, and an external thread is provided on the outer peripheral wall of the second quick connector 120. The internal thread and the external thread cooperate with each other to improve the sealing of the connection, avoid air leakage or liquid leakage, and facilitate disassembly and assembly.

[0048] In addition, the collection container 200 of this embodiment is provided with an exhaust head 210, wherein the exhaust component is used to exhaust the inside of the collection container 200 through the exhaust head 210. Specifically, the exhaust component of this embodiment includes a pressing airbag 300, and the pressing airbag 300 is provided with an air inlet 310 and an air outlet 320. The air inlet 310 is connected to the exhaust head 210 through a first air pipe 311, and the air outlet 320 is connected to the outside.

[0049] In this embodiment, a first one-way valve 400 is installed between the air inlet 310 and the air extraction head 210 . The flow direction of the first one-way valve 400 is from the air extraction head 210 to the direction of pressing the airbag 300 .

[0050] During intestinal irrigation, this embodiment extracts the gas in the collection container 200 by reciprocatingly pressing the pressing airbag 300 to form a negative pressure in the collection container 200, which has a suction effect on feces and irrigation water, so that the cleansing materials in the intestine are discharged. The first one-way valve 400 located at the air inlet 310 of the pressing airbag 300 is used to realize the outward flow of the internal gas of the collection container 200 and block the inward flow of the gas in the pressing airbag 300, so that the pressing airbag 300 only evacuates the collection container 200.

[0051] Furthermore, the air outlet 320 of this embodiment is provided with a second air pipe 321 , and an exhaust head 330 is installed at one end of the second air pipe 321 away from the air outlet 320 . The exhaust head 330 is matched with the first quick connector 220 and is detachably connected.

[0052] like Figure 3 As shown, after the collection container 200 collects to the preset capacity, when the collection container 200 is removed from the drainage tube 100, the exhaust head 330 can be connected to the first quick connector 220 to seal the first quick connector 220. At this time, the collection container 200 and the pressing airbag 300 are connected to form a whole for unified recycling processing, and there is no need to set up other additional sealing parts to seal the first quick connector 220; and during normal irrigation, the first quick connector 220 is connected to the second quick connector 120 to achieve communication between the drainage tube 100 and the collection container 200, and the exhaust head 330 is used to exhaust air outward.

[0053] The outer peripheral wall of the exhaust head 330 of this embodiment is also provided with an external thread matching the internal thread, which improves the sealing of the connection, avoids air and liquid leakage, and is convenient for disassembly and assembly.

[0054] In this embodiment, a second one-way valve 500 is installed in the second air pipe 321. The flow direction of the second one-way valve 500 is set outward. The second one-way valve 500 can prevent external air from entering the pressing airbag 300. When the pressing airbag 300 is pressurized and reset, the pressing airbag 300 only evacuates the collection container 200. When the pressing airbag 300 is pressed, the gas in the pressing airbag 300 can pass through the second one-way valve 500 and be discharged outward along the second air pipe 321.

[0055] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments.
