Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an external liquid collection bag for human wounds and stomas. Background Art

[0002] An external liquid collection bag for human wounds and stomas is a container for collecting and containing human excreta, which is fixed at the wound. However, after the existing external liquid collection bag for human wounds and stomas is fixed at the wound, the wound is enclosed inside the external liquid collection bag for human wounds and stomas. If the wound needs to be treated, it is necessary to remove and replace the external liquid collection bag for human wounds and stomas, which greatly increases the operational complexity. In addition, during the use of the external liquid collection bag for human wounds and stomas, under the action of external force, the liquid inside the external liquid collection bag for human wounds and stomas is likely to flow back to the wound, increasing the risk of wound infection and the like. Content of the Utility Model

[0003] The utility model provides an external liquid collection bag for human wounds and stomas to solve the above technical deficiencies, which can realize the treatment of the wound without removing the bag body at the human wound and stoma, and is also convenient for observing the wound.

[0004] The utility model discloses an external liquid collection bag for human wounds and stomas, which comprises a bag body and a chassis. The chassis is arranged on one side of the bag body. A drain valve is arranged at the end of the bag body. An opening is arranged on the other side of the bag body opposite to the side of the bag body with the chassis. An operation bag is arranged on the side of the bag body at the opening. One end of the operation bag is communicated with the bag body. A sealing mechanism is arranged at the bag mouth at the other end of the operation bag. The sealing mechanism is used to open and close the bag mouth of the operation bag.

[0005] In order to make the operation more convenient and the observation clearer, the opening on the bag body is opposite to the position of the cuttable opening of the chassis. The opening on the bag body should be larger than the maximum diameter of the cuttable opening of the chassis. The end of the operation bag extends into the opening, and the operation bag is hermetically connected to the periphery of the opening of the side bag body of the opening.

[0006] The opening on the bag body is arranged horizontally and covers the width direction of the bag body.

[0007] The operation bag is a flat bag that can be unfolded into a hollow cylindrical structure. One end of the operation bag is sealed and connected to the opening of the bag body, and the other end of the operation bag is the bag mouth. The optimal solution for the opening on the bag body is to run across the width direction on the side wall of the bag body. The end of the operation bag is basically the same length as or slightly shorter than the opening. The operation bag extends into the opening and is sealed and welded to the side wall of the bag body. The operation bag is sealed to the periphery of the opening of the bag body. The welding part between the operation bag and the opening of the bag body is located at the secondary end of the operation bag, that is, there is a certain distance between the welding part and the end of the operation bag extending into the opening of the bag body. Since the thickness of the welding part between the operation bag and the bag body increases, the flatness will be affected to a certain extent. In this solution, the welding part is set at the secondary end of the operation bag, so that the end of the operation bag is still in a flat state. When the liquid collection bag is in normal use, the operation bag is flattened, and the end of the operation bag located inside the opening of the bag body can be flattened and overlapped, and the two will adsorb together, so the seepage liquid will flow into the bag body and will not enter the operation bag.

[0008] The bag body, the chassis, the drainage valve and the connections between them are all prior arts and will not be described in detail here. The lower end of the operation bag is arranged on the bag body at the opening, and the opening on the bag body is within the range of the operation bag, and the opening corresponds to the chassis. When the external liquid collection bag for human wounds and stomas is in use, according to actual needs, the sealing mechanism on the operation bag can be opened, and the wound corresponding to the chassis of the external liquid collection bag for human wounds and stomas, the human wound, and the opening on the external liquid collection bag for human wounds and stomas are all exposed within the range of the operation bag. Operating tools can be inserted into the operation bag from the bag mouth to operate on the wound, improving the operation convenience. Especially for cases where the wound needs to be frequently operated, when operating on the wound, there is no need to remove the external liquid collection bag for human wounds and stomas, which is convenient to operate, safe and reliable. When not in operation, the bag mouth of the operation bag can be directly sealed by using the sealing mechanism. After sealing, the operation bag can be placed flat outside the bag body, and the part of the operation bag extending into the bag body will also be flat and reattached to each other, and the seepage liquid will flow into the bag body of the external liquid collection bag for human wounds and stomas and will not enter the operation bag.

[0009] Diaphragms are provided on two side walls inside the bag body. The upper ends of the diaphragms are hermetically connected to the side walls on the same side. The lower ends of the two diaphragms are partially connected, and a liquid discharge channel is formed at the unconnected part. The upper edge of the diaphragm connected to the side wall of the bag body provided with the chassis is located below the cut-openable opening of the chassis. The end of the bag body where the chassis is provided is called the upper end, and the end of the bag body where the liquid discharge valve is provided is called the lower end. The upper end of the diaphragm refers to the end close to the chassis on the bag body, and the diaphragm is hermetically connected to the bag body, while the lower end of the diaphragm is not connected to the bag body, and the lower ends of the two diaphragms are partially connected. During normal use, the exudate from the wound enters the inside of the bag body from the chassis and flows downward along the bag body, passes through the liquid discharge channel formed between the diaphragms, and enters the lower bag body. Then, there is no exudate retained inside the bag body above the diaphragm, which can keep the wound clean. In addition, when the bag body is externally squeezed, the pressure inside the bag body increases, which will squeeze the lower ends of the two diaphragms together, thereby closing the liquid discharge channel. The exudate in the lower bag body cannot flow back through the liquid discharge channel to the upper bag body, so it will not contaminate the wound, greatly reducing the possibility of wound infection and improving safety. The partial connection below the diaphragm can adopt intermittent spot welding to ensure that the diaphragms are kept flat, making the closure of the liquid discharge channel between the diaphragms more reliable when the bag body is accidentally stressed.

[0010] A connecting plate is provided on the side wall of the bag body on the same side below the operation bag. One or more through holes are provided on the connecting plate, and the through holes penetrate the side wall of the bag body on the same side. Since the through holes penetrate the bag body, in actual use, if it is necessary to extend a tube or the like into the bag body, it can enter through the through holes and can be retained for a long time. A connecting plate is provided on the side wall of the bag body outside the through holes. The connecting plate is usually made of elastic materials such as silica gel and elastic plastic. The connecting plate is also provided with corresponding through holes, which can keep the tube stable during use and ensure the sealing performance between the bag body and the tube. Since the bag body is made of plastic film, directly inserting the tube into the through hole will cause deformation of the through hole or even rupture of the bag body. Setting the connecting plate outside the bag body can effectively keep the tube stable and avoid situations such as deformation of the through hole and rupture of the bag body, effectively improving safety and service performance.

[0011] If there are multiple through holes on the connecting plate, they can be arranged in a row from one end to the other with the diameter of the through holes increasing from small to large. The through holes on the connecting plate are arranged in a row and arranged according to the diameter increasing from small to large, so that it is more suitable for different tube diameters during use and more convenient for operation. Of course, the arrangement order of the through holes can also be selected according to actual needs. The through holes can penetrate or not penetrate the side wall of the bag body on the same side. If they penetrate, plugs or tapes are needed to seal the unused through holes during use; if they do not penetrate, tools such as scissors and needles can be used to penetrate the through holes according to needs.

[0012] The sealing mechanism is as follows: self-sealing strips are oppositely arranged on the inner side of the opening of the operation bag; or the sealing mechanism is: a sealing clip is arranged at the opening of the operation bag. The sealing mechanism can be selected according to actual needs to seal the bag mouth of the operation bag. The sealing clip directly clamps the bag mouth, which is convenient to operate. The sealing clip is a commercially available product, and its specific structure will not be elaborated. The self-sealing strip is an existing product, most commonly used on existing plastic-sealed bags, and can also be in the form of a plastic zipper, etc., with a principle similar to that of the self-sealing strip. The sealing mechanism is not limited to the above several forms, and can also be in the form of a magic tape, etc.

[0013] A non-woven fabric layer or other skin-friendly fabric is provided on the outer surface of the bag body on the side where the chassis is arranged. The side of the bag body with the chassis contacts the human body, so a non-woven fabric layer or skin-friendly fabric is provided. The non-woven fabric layer or skin-friendly fabric is in direct contact with the human body, providing high comfort.

[0014] The length of the operation bag is 2 - 10 cm, and an appropriate length can be selected according to actual needs, such as 3 cm, 4 cm, 5 cm, 8 cm, etc. Of course, it is not limited to the above example values.

[0015] A human body wound and stoma external liquid collection bag obtained by the present utility model is provided with an operation bag, realizing that the wound can be treated without removing the human body wound and stoma external liquid collection bag, which is safe and convenient, and is also convenient for observing the wound.
