Description

Technical Field

[0001] This utility model relates to the field of gastrointestinal decompression and drainage bag technology, and more specifically, to a negative pressure balloon and a gastrointestinal decompression and drainage bag. Background Technology

[0002] Gastrointestinal decompression involves inserting a gastric tube through the mouth or nose, connecting it to a gastrointestinal decompression device, and using negative pressure and siphon principles to suction out gas and fluid from the gastrointestinal tract, thereby reducing the pressure within the gastrointestinal tract.

[0003] Gastrointestinal decompression, one of the most basic nursing procedures in general surgery, is a method to remove gastric contents and gas from the patient's body. Especially for patients undergoing digestive tract anastomosis, it can reduce gastrointestinal tension, prevent excessive gastric distension, reduce anastomotic tension, promote anastomotic healing, effectively improve gastrointestinal function, reduce abdominal distension, improve blood circulation in the gastrointestinal wall, promote localization of inflammation, facilitate the removal of gastric contents, and accelerate recovery. It is widely used.

[0004] The gastrointestinal decompression bags widely used in clinical practice achieve negative pressure drainage by manually squeezing the negative pressure balloon. However, if the squeezing force is too great, the negative pressure balloon may collapse completely and fail to rebound normally, thus failing to provide normal negative pressure suction. In severe cases, this can damage the gastric mucosa and cause gastric bleeding.

[0005] Therefore, how to improve the situation where the negative pressure balloon completely collapses and cannot rebound normally has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a negative pressure balloon to improve the situation where the negative pressure balloon completely collapses and cannot rebound normally.

[0007] Another key aspect of this invention is the disclosure of a gastrointestinal decompression drainage bag comprising the aforementioned negative pressure balloon.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A negative pressure balloon, comprising:

[0010] The balloon body is hollow and has connectors at both ends that can connect the inlet and outlet tubes.

[0011] An elastic pad is installed inside the balloon body, with the pressing area of ​​the balloon body corresponding to the coverage area of ​​the elastic pad.

[0012] Optionally, in the aforementioned negative pressure balloon, the elastic pads are arc-shaped, and the number of elastic pads includes at least two that are arranged opposite each other.

[0013] Optionally, in the aforementioned negative pressure balloon, the elastic pad is snapped into the balloon body.

[0014] Optionally, in the aforementioned negative pressure balloon, the elastic gasket is bonded to the balloon body.

[0015] Optionally, in the above-mentioned negative pressure balloon, the elastic gasket is annular, and the two ends of the elastic gasket corresponding to the inlet and outlet pipes are open.

[0016] Optionally, in the aforementioned negative pressure balloon, the color of the compression area of ​​the balloon body is different from the color of the balloon body; and / or,

[0017] The pressure area of ​​the balloon body is designed with a preset shape or pattern.

[0018] Optionally, in the above-mentioned negative pressure balloon, the elastic gasket is a metal gasket, an alloy gasket, or a non-metallic gasket.

[0020] Optionally, in the above-mentioned negative pressure balloon, the balloon body is made of silicone, rubber, or polyurethane.

[0021] A gastrointestinal decompression drainage bag, comprising the aforementioned negative pressure balloon.

[0022] As can be seen from the above solutions, the negative pressure balloon disclosed in this utility model, by setting an elastic pad inside the balloon body, utilizes the good resilience of the elastic pad to reduce the occurrence of the balloon body completely collapsing and failing to rebound normally due to excessive force applied by the operator, thus ensuring the normal use of the negative pressure balloon. The gastrointestinal decompression drainage bag disclosed in this utility model has the same technical effect as the negative pressure balloon, and will not be described in detail here.

[0026] Among them, 10 is the balloon body, 11 is the pressing area, 20 is the elastic pad, 30 is the one-way valve, 40 is the inlet tube, and 50 is the outlet tube. Detailed Implementation

[0027] The core of this invention is to disclose a negative pressure balloon to improve the situation where a negative pressure balloon completely collapses and cannot rebound normally.

[0028] Another key aspect of this invention is the disclosure of a gastrointestinal decompression drainage bag comprising the aforementioned negative pressure balloon.

[0029] 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.

[0030] like Figure 1 As shown in the figure, this utility model embodiment discloses a negative pressure balloon, including a balloon body 10 and an elastic pad 20.

[0031] The balloon body 10 has a hollow structure, and its two ends are respectively provided with connectors that can connect the inlet tube 40 and the outlet tube 50, as detailed below. Figure 2 As shown. The elastic pad 20 is disposed inside the balloon body 10, and the pressing area 11 of the balloon body 10 is correspondingly disposed with the coverage area of ​​the elastic pad 20.

[0032] The elastic pad 11 provides support for the balloon body 10 and also possesses good elasticity and deformation capacity, allowing it to deform under external force and return to its original shape after the force is removed. When the operator presses the pressing area 11 of the balloon body 10, the balloon body 10 and the elastic pad 20 are compressed together, causing deformation and drawing liquid into the balloon body 10 through the inlet tube 40. When the operator stops applying pressure to the balloon body 10, the elastic pad 11 returns to its original position, and the balloon body 10 simultaneously returns to its original shape.

[0033] The negative pressure balloon disclosed in this embodiment of the utility model, by setting an elastic pad 20 inside the balloon body 10, can reduce the occurrence of the balloon body 10 completely collapsing and failing to rebound normally due to excessive force applied by the operator, by utilizing the good resilience of the elastic pad 20, thus ensuring the normal use of the balloon body 10.

[0034] Furthermore, in some specific embodiments, the elastic pad 20 is arc-shaped, and the number of elastic pads 20 includes at least two oppositely arranged, with the pressing area 11 corresponding to the elastic pad 20. For example... Figure 1 As shown in the figure, there are two elastic pads 20, which are disposed opposite to each other on the upper and lower parts of the balloon body 10. Of course, there can be four elastic pads 20, which are disposed on the upper and lower sides and the front and rear sides of the balloon body 10, respectively. The pressing area 11 is disposed corresponding to the elastic pads 20, and the operator can press the balloon body 10 up and down or back and forth.

[0035] Furthermore, the elastic gasket 20 and the balloon body 10 can be connected by a snap-fit ​​connection. Specifically, elastic gasket connectors can be provided at both ends of the balloon body 10, and the elastic gasket connectors have grooves, into which the elastic gasket 20 can be embedded. Rubber can be injected into the balloon body 10, with grooves reserved to accommodate the elastic gasket 20.

[0036] It should be noted that the surface of the elastic pad 20 facing the balloon body 10 is either in contact with or at a predetermined distance from the balloon body 10, preferably at that predetermined distance.

[0037] In some other specific embodiments, the elastic pad 20 and the balloon body 10 can be connected by adhesive bonding, with both ends of the elastic pad 20 being bonded to the balloon body 10.

[0038] Furthermore, in some specific embodiments, the elastic pad 20 is annular in shape, and the two ends of the elastic pad 20 corresponding to the inlet tube 40 and the outlet tube 50 are open structures. Preferably, the shape of the elastic pad 20 is the same as the shape of the balloon body 10.

[0039] Furthermore, such as Figure 2 As shown, to ensure that the operator presses in the preset direction, the pressing area 11 of the balloon body 10 is clearly marked. Specifically, it can be distinguished by color, with the pressing area 11 being a different color from the balloon body 10; or it can be marked with text, or the pressing area 11 can be given a preset shape or pattern to facilitate the operator's differentiation and ensure that the operator presses in the preset direction so that the elastic pad 20 can function.

[0040] Furthermore, the elastic gasket 20 is made of metal, alloy, or non-metallic materials, such as rubber or polyurethane.

[0041] Furthermore, in order to prevent liquid backflow, a one-phase valve is provided at least on the connector connecting the inlet pipe 40. That is, a one-way valve 30 can be provided only on the connector connecting the inlet pipe 40, or a one-way valve 30 can be provided on both the connector connecting the inlet pipe 40 and the outlet pipe 50.

[0042] Furthermore, the balloon body 10 is made of silicone, rubber, or polyurethane.

[0043] In addition, this utility model embodiment also discloses a gastrointestinal decompression drainage bag, including the above-mentioned negative pressure balloon.
