Description

Technical Field

[0001] The utility model relates to the field of disposable medical accessories, in particular to a seepage collection device. Background Art

[0002] Peritoneal drainage is one of the most commonly used and important basic techniques in abdominal surgery. By placing a drainage tube in the abdominal cavity, the exudate and pus in the abdominal cavity are drained to the outside of the body, promoting wound healing in the body and avoiding secondary infection. In recent years, peritoneal drainage technology has been widely used in the adjuvant treatment of patients with a large number of ascites caused by various reasons, alleviating the pain and mental stress caused by the need for multiple and repeated punctures to drain the ascites. However, during the continuous drainage process, leakage from the drainage tube orifice is often seen in clinical practice. Frequent dressing changes not only increase the risk of retrograde infection and tube slippage in patients, but also increase the psychological pressure of patients and their families, and increase the workload of medical staff.

[0003] Thoracentesis is a common method for treating pleural effusion in clinical practice. It can be used to drain the fluid through an indwelling drainage tube, and it is also convenient for medication to be given through the drainage tube. The indications for thoracentesis are patients with a large amount of pleural effusion that appears repeatedly and continuously in the chest cavity due to reasons such as tumors, without obvious adhesions, wrapping or separation, and that cannot be completely drained out with a few extractions, and that continues to be generated or requires repeated punctures, flushing and injections. Thoracentesis can reduce the number of punctures, thereby alleviating the patient's pain.

[0004] In clinical work, due to various reasons, the abdominal or thoracic drainage tube is often left in place, resulting in excessive accumulation of fluid in the abdominal or thoracic cavity, and a large amount of fluid seeping from the drainage tube at the puncture site, which soaks the patient's skin, bed sheets or clothes, causing skin flushing, dermatitis or even ulceration. The patient is in pain and discomfort, which greatly increases the psychological burden on the patient and his family.

[0005] In the prior art, the treatment of indwelling abdominal or chest drainage tubes at the puncture site generally adopts absorbent medical dressings, such as gauze, foam dressings, etc. to absorb exudate. Although this method can have a certain effect in the short term, once the absorbent medical dressing is saturated, it can no longer absorb the exudate. If exudate occurs at the puncture site, the dressing should be replaced in time; if the dressing is loose, contaminated, or its integrity is damaged, it should be replaced immediately. The current prevention and treatment methods require skilled medical staff to handle, and the operation is relatively complicated; after exudate occurs at the puncture site, the dressing needs to be replaced repeatedly, and the patient's puncture point is prone to infection.

[0045] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0046] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0047] In the prior art, the problem of exudation at the puncture site of an indwelling abdominal or thoracic drainage tube and various complications after exudation are difficult problems faced in clinical nursing. If the exudation at the puncture point can be reasonably controlled, the occurrence of complications can be reduced to a great extent.

[0048] In view of the existing treatment method of exudate from abdominal or thoracic puncture points, the present application discloses an exudate collection device, which solves the problem of drainage fluid leakage from the puncture point after clinical catheterization, can ensure the dryness of the skin at the puncture site, and the dryness and cleanliness of the patient's clothes, bed, etc., and can also avoid infection caused by repeated replacement of auxiliary materials.

[0049] like Figure 1-Figure 5 As shown, the seepage collection device in the present invention comprises: a seepage barrier body 100 .

[0050] The liquid seepage barrier body 100 includes a closed annular structure 110, and the annular structure 110 has a first end surface 111 for mutual contact with the skin around the puncture point of the human body. The inner wall surface 112 of the annular structure 110 is used to block the liquid seepage from the puncture point of the human body. The liquid seepage barrier body 100 has a through hole 114 for the drainage tube to pass through.

[0051] Compared with the prior art method of directly applying a medical dressing to the skin around the puncture point, the exudate barrier body 100 in the utility model is equivalent to a chassis fixed to the skin around the puncture point. The exudate barrier body has a certain thickness and can support the medical dressing, which not only achieves the sealing of the puncture point, but also avoids direct contact between the puncture point and the medical dressing, making the wound at the puncture point breathable and reducing the risk of infection; the exudate barrier body can also avoid accidental touching and secondary damage to the wound at the puncture point when changing the medical dressing, and can have a better protective effect on the wound at the skin puncture point; the exudate barrier body can also collect exudate from the puncture point, solving the problem of drainage fluid leakage from the puncture point after clinical catheterization; the exudate barrier body has a through hole for the drainage tube to pass through, avoiding the phenomenon of loosening and tube falling due to leakage when replacing the medical dressing.

[0052] The exudate barrier body of the embodiment of the utility model is used in conjunction with a medical dressing, and there are two implementation methods. First, the exudate barrier body and the medical dressing are designed to be separated, that is, the medical dressing can be repeatedly applied to the upper end surface of the exudate barrier body. When the medical dressing is replaced, it will not come into contact with the skin around the puncture point, thereby avoiding the problem of exudate caused by repeated replacement of the medical dressing and avoiding infection. Second, the exudate barrier body and the medical dressing are designed to be integrated. This design is to pre-fix the medical dressing on the exudate barrier body. When the exudate barrier body is applied, the medical dressing is fixed at the same time. The top of the exudate barrier body is sealed by the medical dressing, or the area of ​​the medical dressing is designed to be larger than the surface of the exudate barrier body, so that the medical dressing can not only cover the upper end surface of the exudate barrier body, but also cover the peripheral area of ​​the exudate barrier body, so that its sealing and fixation to the drainage tube are better.

[0053] In some embodiments, Figure 6 As shown, the first end surface 111 of the liquid barrier body 100 has an adhesive layer for sealing with the skin around the puncture point of the human body. Further, the adhesive layer is made of a material that is close to human skin and can ensure close contact with human skin without leakage or seepage.

[0054] In some embodiments, Figure 6 As shown, the device also includes: a film layer 200, which is attached at least to the second end face 113 of the liquid permeation barrier body 100 to achieve inner ring sealing of the annular structure 110, and the second end face 113 is the end face opposite to the first end face 111 of the annular structure 110.

[0055] exist Figure 6In the embodiment, the film layer 200 can be a transparent film or a medical dressing in the prior art, such as a disposable hydrocolloid transparent dressing, alginate dressing, gelatin sponge, or a gauze dressing combined with an external transparent film dressing. Optionally, the film layer 200 is designed to be a transparent material at least in the inner ring position of the annular structure 110, so as to facilitate the observation of the exudate at the catheter puncture point; further, the film layer 200 has good elasticity and self-adhesion, is convenient and comfortable to use, is waterproof and breathable, prevents secondary infection, and effectively prevents the occurrence of inflammation. Optionally, the second end surface 113 of the exudate barrier body 100 has a surface that is convenient for bonding with the film layer 200.

[0056] In the above embodiment, since the film layer 200 does not come into direct contact with the puncture point and the patient's skin, the film layer 200 is rarely contaminated, which greatly reduces the need for repeated replacement of the film layer 200.

[0057] The film layer 200 not only seals the inner ring position of the annular structure, but also covers a larger area position. Figure 6-Figure 8 As shown, the film layer 200 is larger than the first end surface 111 and is used to be attached to the annular structure 110 and the surrounding skin outside. Figure 8 As shown, in another embodiment, the annular structure 110 has an outer side surface 118, and the outer side surface 118 is a transition slope or a transition arc surface for achieving smooth attachment of the film layer 200, and the width of the annular structure 110 at the first end surface 111 is greater than the width at the second end surface 113.

[0058] In some embodiments, Figure 7 As shown, the device further includes: a sealed drainage bag 300, which is used to be connected to the exudate barrier body 100 to collect the exudate in the exudate barrier body 100. The sealed drainage bag 300 is used to collect the exudate in the exudate barrier body 100 to prevent the exudate in the exudate barrier body 100 from accumulating too much and seeping out, causing infection or contamination of the patient's clothes and bed.

[0059] Furthermore, if Figure 7 As shown, the sealed drainage bag 300 is provided with an anti-reflux structure 310 for preventing the liquid in the sealed drainage bag 300 from flowing back into the liquid seepage barrier body 100. Optionally, the anti-reflux structure 310 may be a one-way valve structure; in other embodiments, the anti-reflux structure 310 may also be arranged in the drainage channel of the liquid seepage barrier body 100.

The outlet 117 is connected with the liquid collecting port 115 through the confluence channel 116, and the outlet 117 is used to communicate with the sealed drainage bag 300. The liquid collecting port 115, the confluence channel 116 and the outlet 117 are used to realize the liquid seepage discharge function of the liquid seepage barrier body 100.

[0062] It should be noted that Figure 1-Figure 4 The dotted line structure in the figure represents the invisible structural lines inside the object, which mainly represent the position and shape of the liquid collecting port 115 and the confluence channel 116.

[0063] Furthermore, the liquid permeation barrier body 100 further includes an extension portion 120 protruding from the annular structure 110, the extension portion 120 extends outward from the annular structure 110, and the outlet 117 of the drainage structure is formed at the end of the extension portion 120 away from the annular structure 110. Figure 7 In the embodiment, although the film layer 200 is attached to the annular structure 110 and the surrounding skin outside it, it does not cover the end of the extension part 120 where the outlet 117 is located, so as to facilitate the removal and replacement of the sealed drainage bag 300. The extension part 120 facilitates the connection between the exudate barrier body 100 and the sealed drainage bag 300, and also facilitates the operation of replacing the sealed drainage bag 300.

[0064] Optionally, the connection between the extension portion 120 and the sealed drainage bag 300 may be a threaded connection, a snap-on connection, or a direct tension connection of an organic material such as rubber, while achieving a sealed connection function.

[0065] Optionally, the annular structure 110 and the extension portion 120 of the liquid permeation barrier body 100 may be an integrally formed structure, but is not limited thereto, and may also be a detachably connected structure.

For example, the liquid collection ports 115 may be arranged at intervals on the entire inner circumference of the liquid seepage barrier body 100. Each of the liquid collection ports 115 is connected to the confluence channel 116, and the outlet port 117 is provided with one, but the invention is not limited thereto.

[0067] In the above embodiment, the extension portion 120 of the liquid barrier body 100 may be disposed at a position corresponding to the lower position of the puncture point to better collect the liquid at the puncture point. Optionally, the extension portion 120 and the through hole 114 for the drainage tube to pass through may be disposed at 90° or 180° intervals on the annular structure 110, but are not limited thereto and may also be other angles.

[0068] In some embodiments, the first end surface 111 of the liquid seepage barrier body 100 is a plane, or a curved surface complementary to the shape of the skin around the puncture point of the human body. Similarly, the second end surface 113 of the liquid seepage barrier body 100 is a plane, or a curved surface complementary to the shape of the medical dressing.

[0069] In some embodiments, the through hole 114 of the liquid permeation barrier body 100 intersects, is tangent to, or is separated from the first end surface 111; Figure 1 and Figure 3 In the embodiment, the through hole 114 of the exudate barrier body 100 intersects with the first end face 111, and an abdominal or thoracic drainage tube (or drainage tube or catheter) is placed through the through hole 114. The diameter of the through hole 114 may be slightly smaller than the outer diameter of the drainage tube to achieve a clamping function; the through hole 114 intersects with the first end face 111, and the drainage tube can be pressed in and pressed out from the first end face 111, which is convenient for medical staff to operate; then the exudate barrier body 100 with the drainage tube pressed in is fixed to the skin around the puncture point of the human body.

[0070] In some embodiments, the annular structure 110 of the liquid permeation barrier body 100 is in the shape of a regular or irregular circle, ellipse, polygon, etc. Optionally, the annular structure 110 of the liquid permeation barrier body 100 is in the shape of a regular circle.
