Description

Technical Field

[0001] This utility model relates to the field of ultrasound-guided catheter-directed exudate collection, specifically a drainage and collection device. Background Technology

[0002] Interventional ultrasound is a method of diagnosis and treatment performed under ultrasound guidance, such as puncture biopsy, fluid drainage, local drug injection, and tumor tissue ablation. Its main characteristic is that, under real-time ultrasound monitoring or guidance, percutaneous puncture or catheter placement techniques are used to achieve further diagnosis or treatment of lesions or targets within the body. Compared with other interventional methods, interventional ultrasound has advantages such as no radiation, simple operation, low cost, precision, safety, and minimal invasiveness, and can be performed in outpatient clinics, at the bedside, and in operating rooms. Currently, various diseases, such as biliary tract diseases, ascites, and tumor puncture, are treated with catheters / pigtail catheters placed under ultrasound guidance for drainage.

[0003] Besides the drainage tube, some exudate cannot be completely drained through it and will seep out from the surgical incision opening. In this case, the exudate needs to be collected. The original practice was to place gauze and cotton pads on the wound to absorb the exudate. However, as the exudate increases, the gauze quickly becomes soaked. If the gauze is not replaced, the exudate will flow down the body. Therefore, the gauze and cotton pads need to be changed every so often. Many patients are unable to get a good night's rest because of this. If the gauze is not changed promptly, yellow exudate will remain on the patient's body, wetting clothes and bedding. Furthermore, this exudate, digestive fluids, bile, etc., can erode the skin, causing ulcers.

[0004] Therefore, drainage bags are currently used to collect exudate; however, this approach still has at least the following problems:

[0005] 1. The drainage tube opening still retains a catheter, making the coordinated use of the catheter and drainage bag a difficult problem. Currently, to solve the problem of coordinating the use of the drainage bag and catheter, it is necessary to first cut the drainage bag to the size of the drainage tube opening to allow the catheter to pass through, then attach the bottom of the drainage bag to the patient's skin surface, and the area above the drainage bag where the catheter passes through must be sealed again with dressing to allow exudate to flow into the drainage bag; however, because the top and bottom of the drainage bag are tightly attached, it is not convenient for exudate to flow into the bag more promptly.

[0006] 2. The tubes also come in different diameters to accommodate different needs, which makes it difficult to collect exudate.

[0007] 3. When patients are wearing drainage bags, it is inconvenient for them to walk, and when they are resting in bed, the blankets should not be pressed down, otherwise the tube will bend and obstruct drainage.

[0008] 4. Currently, drainage bags are simply discarded into medical waste bins after use. This results in the leakage of internal liquids and the waste generated during use cannot be disposed of in a sealed state. Utility Model Content

[0009] The purpose of this invention is to at least solve the problem of inconvenient collection of exudate during current ultrasound-guided interventional catheterization.

[0010] To solve the above-mentioned technical problems, the present invention provides a drainage and collection device, comprising:

[0011] The lower layer of the drainage bag has a fixedly connected adhesive layer on its lower surface; the adhesive layer has a first tube insertion hole;

[0012] The upper layer of the drainage bag is located on the surface above the lower layer of the drainage bag, and the edge of the upper layer of the drainage bag is fixedly connected to the lower layer of the drainage bag. The upper layer of the drainage bag and the lower layer of the drainage bag form a complete bag body; one side of the bag body is connected to a drain port.

[0013] A support cover is fixedly or detachably connected to the upper layer of the drainage bag; the support cover has a second tube insertion hole.

[0014] In a preferred embodiment of the drainage and collection device of this utility model, the support cover is a component connected to the upper layer of the drainage bag or a component of the upper layer of the drainage bag.

[0015] In a preferred embodiment of the drainage and collection device of this utility model, the diameter / cross-section of the second insertion through hole is smaller than or similar to the diameter / cross-section of the first insertion through hole.

[0016] In a preferred embodiment of the drainage and collection device of this utility model, the second tube through hole is located on the side or above the support cover.

[0017] In a preferred embodiment of the drainage and collection device of this utility model, the support cover is replaced by a support frame, which is connected to the upper surface of the lower layer of the drainage bag or the lower surface of the upper layer of the drainage bag.

[0018] In a preferred embodiment of the drainage and collection device of this utility model, the support frame is replaced by a support protrusion.

[0019] As a preferred embodiment of the drainage and collection device of this utility model, it includes an elastic sealing tube, which is fixedly connected or detachably connected to the second tube placement through hole.

[0020] In a preferred embodiment of the drainage and collection device of this utility model, the diameter of the end of the elastic sealing tube connected to the second tube through hole is larger than the diameter of the other end.

[0021] In a preferred embodiment of the drainage and collection device of this utility model, the second tube insertion hole has a detachably connected sealing cap.

[0022] In a preferred embodiment of the drainage and collection device of this utility model, the second tube through hole is replaced with an interface.

[0023] Beneficial effects

[0024] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:

[0025] This utility model of drainage and collection device, through the setting of a support cover, creates a certain space between the upper and lower layers of the drainage bag, which facilitates the flow of exudate into the bag body from the first tube through hole, thus solving the problem that the upper and lower layers of the current drainage bag are too tightly fitted, making it difficult to collect exudate.

[0026] This utility model of drainage and collection device sets the diameter of the first insertion tube through hole to be larger than the diameter of the second insertion tube through hole. This results in a smaller gap between the second insertion tube through hole and the insertion tube after the insertion tube passes through the first insertion tube through hole and the second insertion tube through hole, which can play a sealing role; while the larger gap between the insertion tube and the first insertion tube through hole can facilitate the seepage into the bag body.

[0027] In this utility model's drainage and collection device, when the second insertion hole is located on the side of the support cover, the insertion tube passing through the second insertion hole can avoid being excessively squeezed and bent by clothing or blankets. This solves the problem that current drainage solutions are prone to bending of the insertion tube by clothing or blankets.

[0028] The drainage and collection device of this utility model, by adding an elastic sealing tube, allows the elastic sealing tube to wrap around the surface of the insertion tube when the insertion tube passes through the second insertion tube through hole, thereby solving or reducing the gap between the insertion tube and the second insertion tube through hole.

[0029] This utility model of drainage and collection device achieves compatibility with tubes of different diameters by setting the structure of the elastic sealing tube to be large at one end and small at the other.

[0030] After use, the new drainage and collection device allows the elastic sealing tube to be discarded inside the bag body, and the second tube opening and / or interface to be sealed with a sealing cap. This solves the problem of garbage sealing, makes it less likely for the seepage inside the bag body to leak out, and also solves the problem of seepage flowing out after the current drainage bags are used.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0042] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0043] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0044] This utility model relates to a drainage and collection device, see [link / reference]. Figures 1 to 4 as well as Figure 9 Includes: Lower layer 1 of the drainage bag, Figure 3 The lower surface of the drainage bag 1 is shown to have a fixedly connected adhesive layer 2, the surface of which has an adhesively connected smooth layer 3, and the shape of the adhesive layer 2 is butterfly-shaped, elliptical, or circular. Figure 2 , Figure 3 and Figure 4 The adhesive layer 2 is shown to have a first tube through hole 4.

[0045] Upper layer 5 of the drainage bag Figure 4 This demonstrates that the upper layer 5 of the drainage bag is located on the surface above the lower layer 1 of the drainage bag, and that the edge of the upper layer 5 is fixedly connected to the lower layer 1 of the drainage bag. Figures 1 to 3 The upper layer 5 and the lower layer 1 of the drainage bag form a complete bag body 6; one side of the bag body 6 is connected to a drain port 7; as shown Figure 1 As shown, the drain port 7 has a detachably connected sealing cap 8;

[0046] Support cover 9, which is fixedly or detachably connected to the upper layer 5 of the drainage bag; see also Figure 4 The support cover 9 has a second tube through hole 10. Figure 4 The support cover 9 is shown to be used to open up the upper layer 5 and the lower layer 1 of the drainage bag, or to create a space between the upper layer 5 and the lower layer 1 of the drainage bag, so that the seepage can flow into the bag body 6 better.

[0047] At least the support cover 9 is made of soft rubber material, and may be made of transparent soft rubber, so as to facilitate medical personnel to view the internal exudate collection.

[0048] This utility model, through the provision of a support cover 9, creates a certain space between the upper layer 5 and the lower layer 1 of the drainage bag, facilitating the flow of exudate into the bag body 6 from the first tube through-hole 4. This solves the problem that the upper and lower layers of the current drainage bag are too tightly fitted, making it difficult to collect exudate.

[0049] Further, see Figure 2 and Figure 3 The support cover 9 is a component connected to the upper layer 5 of the drainage bag or is a component of the upper layer 5 of the drainage bag.

[0050] Furthermore, Figure 4It is shown that the diameter / cross-section of the second insertion through-hole 10 is smaller than that of the first insertion through-hole 4, but this is not the only possibility. The diameter / cross-section of the second insertion through-hole 10 can also be similar to that of the first insertion through-hole 4. This invention sets the diameter of the first insertion through-hole 4 to be larger than the diameter of the second insertion through-hole 10. This results in a smaller gap between the second insertion through-hole 10 and the insertion tube after the tube passes through the first insertion through-hole 4 and the second insertion through-hole 10, which provides a sealing effect; while a larger gap between the insertion tube and the first insertion through-hole 4 facilitates the flow of seepage into the bag body 6.

[0051] Furthermore, Figure 1 , Figure 2 and Figure 4 The second tube through-hole 10 is shown to be located on the side of the support cover 9; Figure 9 This demonstrates the application effect of Embodiment 1. The insertion tube 17 passes through the first insertion hole 4 and then through the second hole 10 from the drainage tube opening, allowing it to be placed flush against the human body surface. Therefore, when the second insertion hole 10 is located on the side of the support cover 9, the insertion tube 17 passing through the second insertion hole 10 can prevent it from being excessively squeezed and bent by clothing or blankets. This solves the problem that current drainage methods are prone to bending the insertion tube by clothing or blankets.

[0052] Furthermore, it includes a resilient sealing tube 13. Figures 1 to 4 The illustrations show the effect of the elastic sealing tube 13 from different angles. The elastic sealing tube 13 is fixedly connected or detachably connected to the second insertion through hole 10. By adding the elastic sealing tube 13, this utility model allows the elastic sealing tube 13 to wrap around the surface of the insertion tube 17 when the insertion tube 17 passes through the second insertion through hole 10, thus solving or reducing the gap between the insertion tube 17 and the second insertion through hole 10.

[0053] Furthermore, Figures 1 to 4 This demonstrates that the diameter of one end of the elastic sealing tube 13 connected to the second insertion through hole 10 is larger than the diameter of the other end. That is... Figure 4 The elastic sealing tube 13 shown gradually narrows from left to right. By designing the elastic sealing tube 13 to be larger at one end and smaller at the other, this invention enables it to be compatible with tubes of different diameters.

[0054] Furthermore, the second through-hole 10 can also be replaced with interface 15. By changing it to interface 15, such as... Figure 4 As shown, the elastic sealing tube 13 can be directly fitted onto the interface 15, enabling quick installation and removal of the elastic sealing tube 13.

[0055] This utility model relates to a drainage and collection device, see [link / reference]. Figure 5 and Figure 6 This embodiment 2 is the same as the scheme of embodiment 1, so the similarities will not be repeated. The difference is that the second tube through hole 10 is located above the support cover 9. Figure 6 The diagram shows the effect of the second tube insertion hole 10 being above the support cover 9. When the second tube insertion hole 10 is above the support cover 9, the tube 17 can be placed in any direction after passing through the second tube insertion hole 10, which increases flexibility. However, when using this solution, care should be taken to prevent the tube from being excessively squeezed and bent from the front by clothing or quilts.

[0056] Furthermore, Figure 5 and Figure 6 The connection between the support cover 9 and the upper layer 5 of the drainage bag is shown to have at least one flow channel 16. This flow channel 16 can also be applied to the solution of Embodiment 1.

[0057] Further, see Figure 5 The second insertion hole 10 has a detachably connected sealing cap 14. The elastic sealing tube 13 is preferably an elastic rubber band hose or silicone hose. After use, the elastic sealing tube 13 can be discarded inside the bag body 6, and the second insertion hole 10 and / or interface 15 can be sealed with the sealing cap 14. This solves the problem of garbage sealing, makes it difficult for seepage inside the bag body 6 to leak out, and also solves the problem of seepage flowing out after the current drainage bags are used.

[0058] This embodiment 3 adopts all the implementation schemes of embodiment 1 or embodiment 2, except that the support cover 9 is replaced with the support frame 11. Figure 8 The illustration shows the effect of support frame 11, but Figure 8 The structure is not unique; the main function of the support frame 11 is to create a space between the lower layer 1 of the drainage bag and the upper layer 5 of the upper flow bag to facilitate the inflow of seepage fluid. In practice, the support frame 11 can be connected to the upper surface of the lower layer 1 of the drainage bag or the lower surface of the upper layer 5 of the drainage bag.

[0059] This embodiment 4 adopts all the implementation schemes of embodiment 1, embodiment 2, or embodiment 3. The difference from embodiment 1, embodiment 2, or embodiment 3 is that the support frame 11 is replaced by the support protrusion 12. Figure 7 The diagram shows the effect of the support protrusion 12, and the support protrusion 12 is preferably installed on the lower layer 1 of the drainage bag.
