Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a detachable embedded abdominal double cannula. Background Art

[0002] Clinically, the purpose of indwelling abdominal drainage tubes after surgery is to drain the effusion and blood in the abdominal cavity and prevent secondary infection and bleeding in the abdominal cavity. In major abdominal surgeries, especially in hepatobiliary surgery, especially in cases of biliary fistula and pancreatic fistula complicated with biliary and pancreatic surgeries, sufficient drainage can not only reduce complications such as infection, digestive tract perforation, and bleeding induced by the fistula, but also help promote the regression of local inflammation and the healing of the fistula opening by appropriately flushing through the drainage tube.

[0003] The existing double cannula system includes two parts: negative pressure drainage and flushing. It is necessary to insert two groups of pipelines into the stoma at the same time, which is not only inconvenient to operate but also increases the discomfort of the patient. At the same time, most of the current abdominal double cannula devices are integrally designed, and each part of the pipe body cannot be disassembled and assembled. The flushing sewage in the abdominal cavity is easy to enter the pipe body, which is inconvenient for subsequent cleaning and has poor practicability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detachable embedded abdominal double cannula to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A detachable embedded abdominal double cannula provided by the utility model includes an outer tube. One end of the outer tube is detachably connected with a three-way pipe, and the other end of the outer tube is provided with a water outlet head. A plurality of round holes are penetrated through the side wall and the inside of the outer tube near one end of the water outlet head, and an inner tube is fixedly connected to the inner bottom of the outer tube near one end of the water outlet head. The end of the inner tube extends out from one end of the three-way pipe, and the water outlet head is detachably connected to the end of the inner tube through a threaded connector.

[0007] When using the above detachable embedded abdominal double cannula, connect the end of the three-way pipe to the negative pressure drainage device, then insert the water outlet head and the outer tube into the abdominal stoma of the patient. Infuse normal saline by connecting a container to the end of the inner tube, so that the normal saline flows from the inner tube to the water outlet head and seeps out, diluting the pus or intestinal contents. At the same time, continuously suck out the flushing liquid through the negative pressure drainage device to complete the drainage. At the same time, the three-way pipe and the water outlet head can be removed for flushing, improving the practicability.

[0008] Preferably, an insertion ring is fixedly connected to the end of the outer tube, and a slot adapted to the insertion ring is opened at the end of the three-way pipe.

[0009] Preferably, a sealing ring is fixedly connected to the circumferential surface of the insertion ring, and a sealing groove adapted to the sealing ring is formed in the insertion slot.

[0010] Preferably, the interior of the water outlet head is designed to be hollow, and the end of the water outlet head is designed to be streamlined. A plurality of water outlet holes communicating with its interior are formed in the side wall of the water outlet head, and the plurality of water outlet holes are evenly distributed in a ring shape.

[0011] Preferably, the threaded connector includes a threaded pipe fixedly connected to the middle of the water outlet head, and the threaded pipe communicates with its interior. One end of the inner pipe close to the round hole is made of rigid plastic and is threadedly adapted to the threaded pipe.

[0012] Preferably, the diameter of the inner pipe is smaller than the diameter of the pipe hole of the tee pipe.

[0013] Preferably, both the outer pipe and the inner pipe are made of rubber.

[0014] The beneficial effects are as follows:

[0015] By connecting the end of the tee pipe to a negative pressure drainage device, then inserting the water outlet head and the outer pipe into the abdominal stoma of the patient, and dripping normal saline into a container externally connected to the end of the inner pipe, the normal saline flows from the inner pipe into the water outlet head and seeps out, diluting the pus or intestinal contents. At the same time, the flushing liquid is continuously sucked out through the negative pressure drainage device to complete the drainage. By integrating the originally multiple instruments responsible for flushing and liquid suction onto one outer pipe, and the pipe body can be disassembled and assembled, the comfort and practicality are improved.

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0023] Refer to Figures 1 - 3 As shown in the figure, the present utility model provides a detachable embedded abdominal double cannula, which includes an outer tube 1. A three-way tube 2 is detachably connected to the end of the outer tube 1. The other end of the outer tube 1 is provided with a water outlet head 3. A plurality of round holes 4 are formed through the side wall and the interior of the outer tube 1 near one end of the water outlet head 3. And an inner tube 6 is fixedly connected to the inner bottom of the outer tube 1 near one end of the water outlet head 3. The end of the inner tube 6 extends out from one end of the three-way tube 2. The water outlet head 3 is detachably connected to the end of the inner tube 6 through a threaded connector.

[0024] Refer to Figure 2 As shown in the figure, an insertion ring 7 is fixedly connected to the end of the outer tube 1. A slot 8 adapted to the insertion ring 7 is formed at the end of the three-way tube 2. A sealing ring 9 is fixedly connected to the circumferential surface of the insertion ring 7. And a sealing groove 10 adapted to the sealing ring 9 is formed in the slot 8. By inserting the insertion ring 7 into the slot 8, the connection between the three-way tube 2 and the outer tube 1 is completed. At the same time, the sealing ring 9 is clamped with the sealing groove 10, achieving the effects of anti-disconnection and sealing.

[0025] Refer to Figure 3 As shown in the figure, the interior of the water outlet head 3 is designed to be hollow, and the end of the water outlet head 3 is designed to be streamlined. A plurality of water outlet holes 5 communicating with its interior are formed on the side wall of the water outlet head 3. And the plurality of water outlet holes 5 are evenly distributed in a ring shape, which can make the water outlet head 3 more comfortable when inserted into the abdominal stoma. At the same time, it can avoid frictional damage inside the intestinal cavity. The annularly distributed water outlet holes 5 can make the flushing liquid seep out more evenly.

[0026] As an optional implementation manner, the threaded connector includes a threaded tube 11 fixedly connected to the middle of the water outlet head 3, and the threaded tube 11 communicates with its interior. One end of the inner tube 6 near the round holes 4 is made of hard plastic material and is threadedly adapted to the threaded tube 11. By rotating the water outlet head 3, the threaded tube 11 can be docked and communicated with the inner tube 6, realizing the disassembly and assembly of the water outlet head 3.

[0027] Furthermore, the diameter of the inner tube 6 is smaller than the diameter of the tube hole of the three-way tube 2, which can be used to maintain the negative pressure intensity inside the outer tube 1. When the negative pressure is too large, the air pressure inside the outer tube 1 can be restored by admitting air through the gap, avoiding the influence of excessive negative pressure generated by the outer tube 1 on the user's body tissues.

[0028] Specifically, both the outer tube 1 and the inner tube 6 are made of rubber, which can make the tube body soft and comfortable.

[0029] With the above structure, during use, the end of the three-way tube 2 is connected to a negative pressure drainage device, and then the water outlet head 3 and the outer tube 1 are inserted into the abdominal stoma of the patient. By externally connecting a container to the end of the inner tube 6 to drip physiological saline, the physiological saline flows from the inner tube 6 to the water outlet head 3 and seeps out, diluting the pus or intestinal contents. At the same time, the flushing liquid is continuously sucked out through the negative pressure drainage device to complete the drainage. Meanwhile, the three-way tube 2 and the water outlet head 3 can be removed for flushing, improving the practicability.

[0030] The above is only a specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
