[0032] Embodiment 1:
[0033] like Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a disposable gastrointestinal decompression drainage device, including a negative pressure drainage bag 1, a drainage docking tube 2 is fixed to the upper end surface of the negative pressure drainage bag 1, and the upper and lower parts of the drainage docking tube 2 are respectively provided with an upper port 201 for docking with a gastric tube, and a lower port 202 connected to the top of the negative pressure drainage bag 1, the diameter of the upper port 201 is smaller than the diameter of the lower port 202, and the drainage docking tube 2 is a truncated cone structure. Specifically, the outer diameter of the upper port 201 is 4.5 mm, the outer diameter of the lower port 202 is 7 mm, and the length of the drainage docking tube 2 is 30 mm, which can be tightly docked with the end of the gastric tube, effectively avoiding the air leakage in the prior art, and having a good use effect.
[0034] An exhaust pipe 3 is also installed on the upper end surface of the negative pressure drainage bag 1. The outer diameters of the upper and lower ports of the exhaust pipe 3 are 1 mm, and the length of the exhaust pipe 3 is 10 mm. It is used to exhaust gas when the air content inside the negative pressure drainage bag 1 is too high, so that the negative pressure drainage bag 1 is in a negative pressure state, and the top of the exhaust pipe 3 is equipped with a sealing plug 301 for sealing after exhaust.
[0035] In addition, a hook 4 for hanging is provided on one side of the top of the negative pressure drainage bag 1, which can be used in conjunction with components such as pins to facilitate hanging the negative pressure drainage bag 1 on the patient's top, and a vertical decompression scale 5 is provided on the side of the negative pressure drainage bag 1. The setting of the decompression scale 5 can facilitate medical staff to quickly and intuitively evaluate the decompression amount.
[0036] Embodiment 2:
[0037] The difference between the second embodiment and the first embodiment described above is that the negative pressure drainage bag 1 is composed of multiple layers of annular materials, which are stacked layer by layer to form a structure similar to a cylinder, so as to facilitate extrusion to form a negative pressure state.
[0038] A bottom plate 6 is fixed to the bottom of the negative pressure drainage bag 1. One side of the upper end face of the bottom plate 6 is fixed with a vertical support rod 601, and the above-mentioned hook 4 is fixed to the top of the support rod 601, so that the hook 4, the support rod 601 and the bottom plate 6 form a simple frame, so as to ensure that the negative pressure drainage bag 1 is not squeezed when the device is hung on the patient's upper garment.
[0039] In addition, a vertical liquid level column 602 is fixed to one side of the upper end of the bottom plate 6. The decompression scale 5 is arranged on the side of the liquid level column 602. The bottom of the liquid level column 602 is communicated with the inner bottom of the negative pressure drainage bag 1 through an air duct in the bottom plate 6, and the top of the liquid level column 602 is connected with a hose 603. The hose 603 is communicated with the top of the negative pressure drainage bag 1 to form a communicating vessel structure, so that the decompression scale 5 can effectively display the drainage liquid level in the negative pressure drainage bag 1 to facilitate medical staff to evaluate the decompression amount. In a specific implementation, in this embodiment, the top end of the hose 603 is fixed to the top of the negative pressure drainage bag 1 by means of insertion.
[0040] The working principle of the present utility model is as follows: by setting the drainage docking pipe 2 with a smaller upper part and a larger lower part, it is convenient to dock with the end of the gastric tube, effectively ensuring the connection effect and avoiding air leakage caused by mismatched caliber docking. And by setting the decompression scale 5 on the side of the negative pressure drainage bag 1, it is convenient for medical staff to quickly and intuitively evaluate the decompression amount. To sum up, this device can not only be conveniently and tightly connected with the gastric tube for use, but also facilitate medical staff to quickly evaluate the decompression amount of the gastrointestinal tract, and the overall use effect is good.
[0041] The present utility model covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.
[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
