Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a fistula drainage device. Background Technology

[0002] During the treatment of some patients, due to their condition, medical staff insert a drainage tube into the patient's body through a stoma. The drainage tube drains the accumulated fluid into an external collection bag to prevent the internal wound from becoming infected and to achieve the desired therapeutic effect.

[0003] Existing stoma drainage devices lack a mechanism to secure the drainage tube. When the collection bag and drainage tube are pulled, the drainage tube is easily detached from the stoma tube, requiring replacement with a new drainage tube, which reduces the efficiency of the drainage tube.

[0004] According to the publication number CN213759808U, a drainage device after stoma surgery includes an intestinal drainage tube and a drainage bag. The first end of the intestinal drainage tube is used to extend into the intestinal tract and is fixed to the intestinal tract through a fixing structure. The second end is used to connect to the drainage bag. The fixing structure includes a ring support sleeved on the first end of the drainage tube. The outer diameter of the ring support is larger than the diameter of the drainage tube and the stoma. The outer support surface of the ring support near the drainage tube is used to abut against the inner wall of the intestinal tract.

[0005] According to the above-described drainage device for post-stomach ostomy, this device achieves convenient replacement of the drainage bag through the threaded connection between the ostomy tube and the drainage device. However, for most ostomy patients, ostomy is only a temporary treatment method. This type of installation is too complicated, and the threaded installation and removal of the drainage bag will cause great pain to the patient. Therefore, we need to propose a drainage device for ostomy. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a stoma drainage device, including a stoma assembly 1, a drainage assembly 3 connected to the bottom of the stoma assembly 1, a fixing assembly 2 for fixing the drainage assembly 3 installed at the bottom of the stoma assembly 1, a cleaning assembly 4 connected to one side of the stoma assembly 1, the stoma assembly 1 including a stoma tube 11 inserted through the patient's stoma, the fixing assembly 2 including two sets of fixing rods 21 fixedly installed at the bottom of the stoma tube 11, a fixing seat 22 fixedly installed at the bottom of the two sets of fixing rods 21, a pressure cap 23 rotatably installed at one end of the fixing seat 22, a set of clamps 26 fixedly installed on the inner side of both the fixing seat 22 and the pressure cap 23, and the drainage assembly 3 including a drainage tube 32 communicating with the bottom of the stoma tube 11, the outer arc surface of the drainage tube 32 being snapped into the inner side of the two sets of clamps 26.

[0027] In this embodiment, as Figure 1 As shown, by setting the bottom fixing component 2 of the stoma tube 11, after the drainage tube 32 is connected to the stoma tube 11, the middle part of the drainage tube 32 is placed inside the fixing seat 22 and a set of clamps 26 are set inside. Then, the pressure cap 23 is rotated to press and close it with the fixing cap. The clamps 26 on the inner side of the pressure cap 23 and the clamps 26 on the inner side of the fixing seat 22 fit together. The inner sides of the two sets of clamps 26 squeeze and clamp the outer arc surface of the drainage tube 32, thereby achieving the effect of fixing one end of the drainage tube 32 to the bottom of the stoma tube 11 at all times. The cleaning component 4 achieves the effect of cleaning and disinfecting the wound inside the patient's body.

[0028] In a further preferred embodiment, such as Figure 2 As shown, each of the two sets of clamping plates 26 has a set of through-tube grooves 29 on its opposite sides. Several sets of anti-slip pads 210 are symmetrically fixed on the inner side of each of the two sets of through-tube grooves 29. The inner side of the several sets of anti-slip pads 210 is pressed and adhered to the outer arc surface of the drainage tube 32. With the setting of several sets of anti-slip pads 210, when the two sets of clamping plates 26 clamp and fix the drainage tube 32, the inner side of the several sets of anti-slip pads 210 forms a closed circle to squeeze and fix the outer arc surface of the drainage tube 32, preventing the drainage tube 32 from sliding up and down and shifting.

[0029] In a further preferred embodiment, such as Figure 3 As shown, one set of clamping plates 26 has several sets of positioning grooves 27 at both ends, and the other set of clamping plates 26 has several sets of fixing pins 28 at both ends. When the two sets of clamping plates 26 are fitted together, one end of each set of fixing pins 28 is engaged with the inside of the several sets of positioning grooves 27. Through the connection between the clamping plates 26, fixing pins 28, and positioning grooves 27, the stability of the mutual clamping between the two sets of clamping plates 26 is further improved.

[0030] Furthermore, such as Figure 3A locking block 24 is fixedly installed on one side of the fixed base 22, and a locking buckle 25 is installed on one side of the pressure cover 23. When the fixed base 22 and the pressure cover 23 are locked together, the locking buckle 25 is engaged with the outside of the locking block 24. When the locking buckle 25 is engaged with the locking block 24, the fixed base 22 and the pressure cover 23 are locked. When the locking buckle 25 is separated from the locking block 24, the locked state of the fixed base 22 and the pressure cover 23 is released.

[0031] Furthermore, such as Figure 2 The stoma tube 11 shown is fixedly fitted with a fixing ring 12 and an inner ring 13 in sequence in the middle. The groove between the fixing ring 12 and the inner ring 13 is used to clamp the patient's stoma. By utilizing the connection between the stoma tube 11, the fixing ring 12 and the inner ring 13, the stoma tube 11 is fixed at the patient's stoma through the fixing ring 12 and the inner ring 13.

[0032] Preferred, such as Figure 1 As shown, the two ends of the fixing ring 12 are fixedly installed with restraint straps 14, and one end of the two sets of restraint straps 14 is provided with a set of Velcro 15. By utilizing the connection relationship between the fixing ring 12, the restraint straps 14 and the Velcro 15, the fixing ring 12 can be fastened to the patient's body surface through the restraint straps 14 and the Velcro 15, thereby further improving the stability of the stoma assembly 1 installation.

[0033] Preferred, such as Figure 4 As shown, the top of the drainage tube 32 is connected to the drainage interface 31, and the top of the drainage interface 31 is connected to the bottom of the stoma tube 11. Through the setting of the drainage interface 31, the drainage tube 32 and the stoma tube 11 can be quickly connected and separated, which facilitates the installation and replacement of the drainage tube 32.

[0034] In addition, such as Figure 4 The bottom end of the drainage tube 32 is connected to a collection bag 33, and the bottom of the collection bag 33 is connected to a drain pipe 34. The collection bag 33 is used to collect the liquid discharged from the drainage tube 32. When the collection bag 33 is full, the liquid can be drained into a designated container by replacing the drainage component 3 or by draining it through the drain pipe 34.

[0035] In addition, such as Figure 4 The surface of the collection bag 33 shown has scale lines 35 printed on it, and a label card 36 is affixed to the surface of the collection bag 33. The scale lines 35 and the label card 36 make it convenient for medical staff to record the amount of fluid discharged.

[0036] It is worth noting that, such as Figure 2The cleaning component 4 shown includes a cleaning interface 41 that communicates with the outer arc surface of the stoma tube 11. One end of the cleaning interface 41 is connected to a fluid delivery tube 42, and the other end of the fluid delivery tube 42 is connected to a cleaning bottle 43. After the accumulated fluid or pus in the patient's body is drained, there will still be residue. At the same time, the internal wound also needs to be cleaned and disinfected. Through the setting of the cleaning component 4, the cleaning fluid in the cleaning bottle 43 is discharged into the inside of the stoma tube 11 through the fluid delivery tube 42. After the cleaning fluid rinses the wound, it is discharged into the collection bag 33 through the drainage tube 32.

[0037] In practical use: By setting up the stoma assembly 1 and the drainage assembly 3, the effect of draining the fluid inside the patient's postoperative wound is achieved. At the same time, by setting up the fixing assembly 2, after the drainage tube 32 is connected to the stoma tube 11, the middle part of the drainage tube 32 is placed inside the fixing seat 22 and a set of clamps 26 are set inside. Then, the pressure cap 23 is rotated to press and close it with the fixing seat 22. The inner sides of the two sets of clamps 26 squeeze and clamp the outer arc surface of the drainage tube 32, thereby achieving the effect of fixing one end of the drainage tube 32 to the bottom of the stoma tube 11 at all times, improving the firmness of the installation between the drainage tube 32 and the stoma tube 11. By setting up the cleaning assembly 4, the effect of cleaning the wound inside the patient's body is achieved.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
