Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gastrointestinal decompressor with a squeezing and exhausting function. Background Art

[0002] The gastrointestinal decompression negative pressure drainage device can suck out the gas or liquid in the gastrointestinal tract, reduce the pressure in the gastrointestinal tract, reduce the degree of gastrointestinal distension, improve the blood circulation of the gastrointestinal wall, and promote the healing of stomach wounds and the recovery of function. The existing gastrointestinal decompression device mainly includes a collecting bag, which is provided with an inlet and an outlet. The inlet is provided with a control valve to control the drainage speed. The control valve is connected to the stomach tube and is used to collect drainage liquid and / or gas. The outlet is used to exhaust or pour out the drainage liquid inside the collecting bag. A spring is provided inside the collecting bag to exhaust the internal gas by compressing the spring and the collecting bag, and the shape of the collecting bag is restored by the spring to generate negative pressure. The existing gastrointestinal decompression device generally requires multiple exhaust operations to generate negative pressure during actual operation. It is not easy to grasp the degree of pressing the spring during operation, especially it is necessary to keep the pressing state to close the outlet. For example, excessive pressing will cause the drainage liquid inside the collecting bag to be discharged from the outlet, polluting the surrounding environment and producing odor.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] As attached Figure 1 To Attachment Figure 3 As shown,

[0021] Specific embodiment: A gastrointestinal decompression device with extrusion exhaust function, comprising a collecting bag 1 and an extrusion exhaust mechanism 2, wherein the top of the collecting bag 1 is provided with an inlet 3 and an outlet 4, the inlet 3 is connected with a first hose 5, the first hose 5 is provided with a flow regulating valve 6, the first hose 5 is connected to a gastric drainage tube, and the outlet 4 is provided with a sealing plug 7; the extrusion exhaust mechanism 2 comprises an upper arc-shaped pressing plate 8 and a lower arc-shaped pressing plate 9, which are respectively arranged at the top and bottom of the collecting bag 1, and the upper arc-shaped pressing plate 8 and the lower arc-shaped pressing plate 9 ... An upper connecting block 10 and a lower connecting block 11 are fixed to the sides of the arc-shaped pressure plate 9, respectively. Two upper connecting rods 12 are hinged on the upper connecting block 10, and two lower connecting rods 13 are hinged on the lower connecting block 11. One group of upper connecting rods 12 and lower connecting rods 13 opposite to each other are hinged to the same moving block 14, and the other group of upper connecting rods 12 and lower connecting rods 13 opposite to each other are hinged to the same fixed block 15. The moving block 14 is threadedly connected to a screw 16, which is rotatably connected to the fixed block 15, and a rotating handle 17 is provided on the screw 16.

[0022] The collecting capsule 1 is a bellows telescopic tube, and the collecting capsule 1 is made of a transparent or translucent hard medical plastic material. A plurality of fixing clips 18 are provided on the upper arc pressing plate 8 and the lower arc pressing plate 9, and the upper arc pressing plate 8 and the lower arc pressing plate 9 are fixed to the collecting capsule 1 by the fixing clips 18. A spring adapted to the corrugation can also be provided inside the collecting capsule 1.

[0023] A card slot is provided at the top of the collecting capsule 1, and an activated carbon adsorption box 19 is connected in the card slot. The outlet 4 at the top of the collecting capsule 1 is connected to the air inlet of the activated carbon adsorption box 19 through a second hose (not shown in the figure). The activated carbon adsorption box 19 is also provided with an air outlet.

[0024] Two pull rings 20 are fixed to the side of the upper arc-shaped pressing plate 8 , and the two pull rings 20 are symmetrically arranged on both sides of the center line of the upper arc-shaped pressing plate 8 , and the screw rod 16 is perpendicular to the center line of the upper arc-shaped pressing plate 8 .

[0025] There are two rotating handles 17 , which are symmetrically arranged on both sides of the screw rod 16 .

[0026] A protruding hanging piece 21 is provided on the top of the collecting bag 1 , and a hanging hole 22 is provided on the hanging piece 21 .

[0027] The first hose 5 is connected to the gastric drainage tube via a threaded plug connector 23. The thread can increase the friction between the threaded plug connector 23 and the gastric drainage tube, ensuring a firm connection and preventing it from falling off.

[0028] When the gastrointestinal decompressor of the utility model is in use, the rotating handle 17 is rotated to drive the screw 16 to rotate, and the screw 16 drives the moving block 14 to move, and the upper arc-shaped pressing plate 8 is pushed up and down by the hinged upper connecting rod 12 and the lower connecting rod 13. When the upper arc-shaped pressing plate 8 moves downward, it squeezes the collection bag 1 and discharges the internal gas from the outlet 4, and then the sealing plug 7 is used to close the outlet 4, and the upper arc-shaped pressing plate 8 is pushed upward to stretch the collection bag 1 to increase its internal space so as to generate negative pressure, and the threaded plug 23 is connected to the tail drainage tube. Under the action of negative pressure, the gastric drainage fluid or gas is discharged into the collection bag 1, and the discharge speed is controlled by controlling the flow regulating valve 6. After collecting for a period of time, the pressure of the negative pressure drops, and it is necessary to re-exhaust. The above exhaust operation can be repeated. When squeezing the collection bag 1, pay attention to stop when the compression reaches the internal liquid level. Since the utility model adopts the method of rotating the screw 16 for adjustment, it is easier to grasp the degree of compression of the collection bag 1 than the existing manual squeezing of the internal spring. When compressing the collection capsule 1 for the second time or later, be sure to connect the activated carbon adsorption box 19, because the drainage fluid or gas discharged from the stomach has a peculiar smell and is easy to pollute the environment, and is adsorbed by the activated carbon adsorption box 19. In addition, if the collection capsule 1 is in a hanging state and there is no support at the bottom, you can hold the pull ring 20 with one hand to stabilize the entire device during operation, and then use the other hand to turn the rotating handle 17.

Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
