Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically relating to a wound exudate collection device. Background Technology

[0002] Peritubular drainage is a common surgical problem. Currently, the main clinical approach is to increase the frequency of dressing changes by surgeons. However, due to the heavy workload in clinical practice, doctors often cannot immediately address the need for dressing changes when peritubular drainage requires them. If the drainage is not changed in time, it can lead to redness and infection of the peritubular skin, causing irritant dermatitis and reducing patient comfort. Frequent dressing changes also increase the patient's medical expenses. Research and market surveys have revealed that hospitals now often use ostomy bags to collect drainage from the wound. A small opening is cut in the front of the ostomy bag, and the drainage tube is passed through the opening and the small opening of the ostomy bag. The small opening is sealed with a tie, which can effectively collect exudate from the drainage tube. However, this method has some shortcomings: when using an ostomy bag to collect exudate from the patient's drainage site, the stored exudate is easily backflowed to the drainage site when the patient turns over or moves, causing skin infection at the drainage site. To avoid this, the drainage site needs to be rinsed to reduce the risk of wound infection. However, due to its structural characteristics, the existing ostomy bag makes it difficult to rinse the wound during use. Based on this, we propose an exudate collection device that can prevent exudate backflow and facilitate wound cleaning. Utility Model Content

[0003] The purpose of this invention is to provide a wound exudate collection device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wound exudate collection device, comprising an ostomy bag body, a first opening on the back of the ostomy bag body, an adhesive layer on the surface of the ostomy bag body at the first opening, a second opening on the front of the ostomy bag body, an anti-backflow component inside the ostomy bag body, and a flushing component installed inside the ostomy bag body at the second opening.

[0005] As a preferred embodiment of the present invention, a sealing ring is provided inside the second opening, and the sealing ring is made of silicone.

[0006] As a preferred technical solution of this utility model, the anti-reflux component includes a funnel-shaped receiving cup installed inside the ostomy bag body. The receiving cup is located at the bottom of the first opening, and a drain pipe is installed at the bottom end of the receiving cup. Folds are provided on both sides of the drain pipe.

[0007] As a preferred technical solution of this utility model, the flushing assembly includes a flushing ring installed inside the ostomy bag body, the flushing ring having a flushing chamber inside, and a flushing hole penetrating the flushing chamber on one side surface of the flushing ring located at the first opening. A connecting pipe is installed on the surface of the ostomy bag body, and the connecting pipe is connected to the flushing ring.

[0008] As a preferred technical solution of this utility model, both the drain pipe and the receiving cup are made of PVC water hose, and the inner wall of the drain pipe is attached together by a set crease.

[0009] As a preferred technical solution of this utility model, a sealing plug is installed at the end of the connecting pipe, and a connecting strip is installed between the sealing plug and the connecting pipe.

[0010] As a preferred technical solution of this utility model, the adhesive layer is a hydrocolloid dressing.

[0011] As a preferred technical solution of this utility model, the centers of the first opening, the flushing ring, and the second opening are on the same axis.

[0012] As a preferred embodiment of this invention, the inner diameter of the sealing ring matches the diameter of the drainage tube, and the inner diameter of the connecting tube matches the nipple size of the syringe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the ostomy bag body is attached to the patient's drainage tube through the adhesive layer, and the drainage tube passes through the first and second openings. Since the adhesive layer is a hydrocolloid dressing, it can not only absorb some of the exudate, but also provide a moist environment for wound healing. The exudate enters the ostomy bag body through the first opening and flows into the bottom of the ostomy bag body through the collection cup and drainage tube. The folds in the design make the inner wall of the drainage tube fit, so that when the patient turns over or moves, the collected exudate cannot flow back to the first opening, thereby avoiding wound infection caused by exudate backflow. The flushing component allows the wound to be flushed during the collection of the patient's exudate, further reducing the risk of wound infection. This collection device has a simple structure and is easy to use, and is worthy of promotion and use in clinical practice. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-5 The present invention provides the following technical solution: a wound exudate collection device, including an ostomy bag body 1, a first opening 2 on the back of the ostomy bag body 1, an adhesive layer 3 on the surface of the ostomy bag body 1 at the first opening 2, a second opening 4 on the front of the ostomy bag body 1, an anti-backflow component 5 inside the ostomy bag body 1, a flushing component 6 installed inside the ostomy bag body 1 at the second opening 4, and a sealing ring 7 made of silicone inside the second opening 4.

[0023] In this embodiment, the anti-backflow component 5 includes a funnel-shaped receiving cup 51 installed inside the ostomy bag body 1. The receiving cup 51 is located at the bottom of the first opening 2. A drain pipe 52 is installed at the bottom end of the receiving cup 51. Folds 53 are provided on both sides of the drain pipe 52. Both the drain pipe 52 and the receiving cup 51 are made of PVC water hose. The inner wall of the drain pipe 52 is attached together by the provided folds 53.

[0024] Specifically, after wound exudate enters the ostomy bag body 1 through the first opening 2, the exudate will flow into the bottom of the ostomy bag body 1 along with the receiving cup 51 and the drainage tube 52. The folds 53 make the inner wall of the drainage tube 52 stick together when there is no external force. Therefore, when the patient turns over or moves, the exudate collected at the bottom of the ostomy bag body 1 will not flow back to the first opening 2, thereby avoiding infection of the patient's wound due to backflow of exudate.

[0025] In this embodiment, the flushing assembly 6 includes a flushing ring 61 installed inside the ostomy bag body 1. The flushing ring 61 has a flushing chamber 62 inside. The flushing ring 61 has a flushing hole 63 on one side surface of the flushing ring 61 that passes through the flushing chamber 62. A connecting pipe 64 is installed on the surface of the ostomy bag body 1 and is connected to the flushing ring 61.

[0026] Specifically, during the process of collecting patient exudate, medical staff can connect the connecting tube 64 to the syringe and inject saline into the irrigation chamber 62 through the syringe. Since the irrigation hole 63 is directly opposite the first opening 2, the saline can rinse the wound located at the first opening 2 through the irrigation hole 63, thereby further reducing the risk of infection caused by exudate.

[0027] In this embodiment, a sealing plug 65 is installed at the end of the connecting pipe 64, and a connecting strip 66 is installed between the sealing plug 65 and the connecting pipe 64.

[0028] Specifically, the sealing plug 65 can seal the end of the connecting tube 64, thus sealing the connecting tube 64 when the patient is not being flushed, and the connecting strip 66 can prevent the sealing plug 65 from being lost.

[0029] In this embodiment, the adhesive layer 3 is a hydrocolloid dressing.

[0030] Specifically, since the adhesive layer 3 is a hydrocolloid dressing, it can not only absorb some of the exudate, but also provide a moist environment for wound healing.

[0031] In this embodiment, the centers of the first opening 2, the flushing ring 61, and the second opening 4 are on the same axis.

[0032] Specifically, since the centers of the first opening 2, the flushing ring 61, and the second opening 4 are on the same axis, it is convenient to insert the drainage tube.

[0033] In this embodiment, the inner diameter of the sealing ring 7 matches the diameter of the drainage tube, and the inner diameter of the connecting tube 64 matches the nipple size of the syringe.

[0034] Specifically, since the inner diameter of the sealing ring 7 matches the diameter of the drainage tube, the sealing ring 7 can seal the side of the drainage tube when the drainage tube passes through it, preventing exudate from flowing out through the gap between the sealing ring 7 and the drainage tube. Since the inner diameter of the connecting tube 64 matches the size of the syringe nipple, it is convenient for medical staff to use a syringe filled with saline to rinse the patient's wound.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
