[0034] Example 1

[0035] A gastrointestinal decompression device includes a container 401 and a guide body 402 connected to each other, wherein the container 401 has a first cavity 403, and the guide body 402 has a second cavity 404, and the first cavity 403 is communicated with the second cavity 404; the guide body 402 is configured as a funnel shape, and the cross-sectional diameter of the guide body 402 gradually decreases from one end facing the container 401 to the end facing away from the container 401; a drainage port 405 is provided at the end of the guide body 402 facing away from the container 401.

[0036] As can be seen from the background technology, in the prior art, the discharge port is set at the bottom of the container, and the bottom inner wall of the container is flat, which results in a large amount of gastric fluid sticking to the bottom inner wall of the container when the gastric fluid in the container is about to leak out from the discharge port, and once the volume of gastric fluid in the container is lower than a certain threshold, the container needs to be shaken continuously to make the gastric fluid in the container flow toward the discharge port, so that the gastric fluid can continue to be discharged, causing inconvenience in the use of the gastrointestinal decompression device. In summary, the core technical problem existing in the prior art is the lack of a guiding component for the gastric fluid in the container to flow toward the discharge port.

[0037] In this embodiment, compared with the prior art, a guide body 402 is added, and the liquid discharge port is set at the end of the guide body 402 away from the containing body 401. At the same time, the guide body 402 is configured to be funnel-shaped, and the cross-sectional diameter of the guide body 402 gradually decreases from the end facing the containing body 401 to the end away from the containing body 401; this results in that in the process of the gastric fluid in the containing body of this embodiment flowing toward the liquid discharge port, the gastric fluid must pass through the guide body 402, and the guide body 402 has a guiding effect on the flow direction of the gastric fluid, and the guide body 402 guides the gastric fluid by the inner part of the containing body. The gastrointestinal decompression device of this embodiment, when in use, only needs to make the axis of the containing body 401 of the gastrointestinal decompression device coincide with the vertical direction, so that the gastric fluid in the containing body 401 can flow toward the drain port 405 through the guide body 402 under the action of gravity, without the need to constantly shake the containing body, which is very convenient to use and can discharge the gastric fluid more thoroughly. Therefore, this embodiment solves the technical problem existing in the prior art that the gastrointestinal decompression device lacks a guiding component for the gastric fluid in the containing body to flow toward the drain port.

[0038] like Figure 1 As shown, further, the present embodiment also includes the following technical solutions: a liquid discharge switch valve is provided at the liquid discharge port 405, and the liquid discharge switch valve can open or cut off the liquid discharge port 405. The liquid discharge switch valve can adopt any switch valve in the prior art that can realize opening and closing the liquid discharge port 405, and the prior art can be checked and will not be described in detail here.

[0039] In this embodiment, if the drain port 405 needs to be closed, the drain switch valve is switched to the closed state, and the drain switch valve cuts off the drain port 405; if the drain port 405 needs to be opened, the drain switch valve is switched to the open state, and the drain port 405 is opened. The purpose of such a setting is that the drain switch valve can be switched to the closed state during the time period when the drain is not required, so as to prevent external dust from entering the first cavity 403 or the second cavity 404 from the drain port 405, and the drain port 405 can be opened at any time when it is needed, which is very convenient.

[0040] like Figure 1 As shown, further, this embodiment also includes the following technical solution: the gastrointestinal decompression device also includes a flexible connector 406 and a clamping portion 407 , one end of the flexible connector 406 is connected to the containing body 401 , and the other end is connected to the clamping portion 407 .

[0041] In this embodiment, preferably, the flexible connecting body 406 is a rope, and the clamping portion 407 is a spring clamp.

[0042] In this embodiment, the containing body 401 and the guiding body 402 can be detachably connected to the clothing of the patient's body through the flexible connecting body 406 and the clamping part 407. When the patient's body position changes or the patient needs to walk, the gastrointestinal decompression device of this embodiment can move with the patient without the need for medical staff to move manually or with the help of tools, so that the gastrointestinal decompression device can move with the patient, which is very convenient.

[0043] like Figure 1 As shown, further, this embodiment also includes the following technical solutions: a first liquid inlet 101 is provided at one end of the containing body 401 away from the guide body 402, and the first liquid inlet 101 is communicated with the first cavity 403; it also includes a first liquid inlet pipe 102, a first flushing pipe 103 and a first-level three-way valve 104, wherein the first liquid inlet pipe 102, the first flushing pipe 103 and the first liquid inlet 101 are respectively connected to the three valve ports of the first-level three-way valve 104.

[0044] The patient's gastric fluid can enter the first cavity 403 and the second cavity 404 through the first liquid inlet tube 102 and the first liquid inlet port 101; in actual use, the first liquid inlet tube 102 is easily blocked by blood clots, undigested food, etc. in the gastric fluid, and therefore needs to be flushed. If the flushing liquid is directly flushed into the first cavity 403 and the second cavity 404 from the first liquid inlet tube 102, the drain port 405 needs to be continuously opened to drain the liquid; therefore, the above-mentioned scheme is designed in this embodiment.

[0045] The gastrointestinal decompression device of the present embodiment, when it is necessary to flush the first liquid inlet pipe 102, adjust the first-level three-way valve 104 so that the first liquid inlet pipe 102 is disconnected from the first liquid inlet port 101, and the first liquid inlet pipe 102 is connected to the first flushing pipe 103. By injecting physiological saline into the first flushing pipe 103, the first liquid inlet pipe 102 is flushed, thereby avoiding the problem of constantly opening the discharge port 405. After flushing, adjust the first-level three-way valve 104 again so that the first liquid inlet pipe 102 is connected to the first liquid inlet port 101, and the first liquid inlet pipe 102 is disconnected from the first flushing pipe 103. The gastrointestinal decompression device of the present embodiment is more convenient when flushing the first liquid inlet pipe 102.

[0046] like Figure 1 As shown, further, the container 401 and the guide body 402 are both made of a transparent or translucent elastic material, such as silicone rubber, which has the characteristic of slow rebound, so that the container 401 and the guide body 402 can recover the deformation after being deformed; the surface of the container 401 and the guide body 402 have a plurality of scale lines along the axis of the container 401, and the volume represented by two adjacent scale lines is 10ML. In this embodiment, the scale is refined to 10ML, so that the medical staff can read the readings more accurately.

[0047] During use, the medical staff manually pinches the containing body 401, closes the liquid discharge switch valve, and then releases the containing body 401. The containing body 401 tends to rebound slowly, resulting in negative pressure in the first cavity 403 and the second cavity 404. The first-level three-way valve 104 is adjusted to connect the first liquid inlet pipe 102 with the first liquid inlet port 101. Under the action of negative pressure, the gastric fluid in the patient's stomach is sucked into the first cavity 403 and the second cavity 404 through the first liquid inlet pipe 102 and the first liquid inlet port 101. The volume of the sucked gastric fluid is read out through the scale lines on the surface of the containing body 401 and the guide body 402. When the gastrointestinal decompression device is full of gastric fluid, the liquid discharge switch valve is opened to discharge the fluid through the liquid discharge port 405.

[0048] Example 2

[0049] This embodiment is improved on the basis of the embodiment 1, and this embodiment focuses on describing the structural parts that are different from the embodiment 1.

[0050] like Figure 2 As shown, in the gastrointestinal decompression device of this embodiment, the containing body 401 and the guide body 402 are both made of transparent or translucent hard materials, such as transparent hard plastics; it also includes a piston body 201, and the outer surface of the piston body 201 is in sliding contact with the inner wall of the containing body 401, preferably in sliding sealing contact; it also includes a connecting rod 202, and an opening is provided at the end of the containing body 401 away from the guide body 402, one end of the connecting rod 202 is connected to the piston body 201, and the other end extends out from the opening; it also includes a spring 203, the spring 203 is coaxial with the connecting rod 202, one end of the spring 203 abuts the piston body 201, and the other end abuts the inner wall of the containing body 401; it also includes a handle 204, and the handle 204 is connected to the connecting rod 202.

[0051] In this embodiment, compared with Embodiment 1, the manner of generating negative pressure in the first cavity 403 and the second cavity 404 is changed. In this embodiment, after closing the discharge switch valve, the medical staff can pull the handle 204 to pull the piston body 201 through the connecting rod 202 to move in a direction away from the second cavity 404, thereby generating negative pressure in the first cavity 403 and the second cavity 404.

[0052] like Figure 2 As shown, further, the present embodiment also includes the following technical solutions: a breathing channel 205 is arranged in the connecting rod 202, and the breathing channel 205 passes through the connecting rod 202 along the axial direction of the connecting rod 202, one end of the breathing channel 205 penetrates the end of the connecting rod 202 extending from the opening, and the other end of the breathing channel 205 penetrates the piston body 201 and communicates with the second cavity 404; at the end of the breathing channel 205 away from the piston body 201, a pressure relief valve 206 is arranged in the breathing channel 205, and the pressure relief valve 206 can cut off or open the breathing channel 205.

[0053] The structure of the pressure relief valve 206 can adopt any valve body in the prior art that has the function of cutting off or opening the breathing passage 205, and is not limited here.

[0054] In this embodiment, in order to avoid excessive negative pressure in the first cavity 403 and the second cavity 404, a breathing channel 205 is provided in this embodiment, and a pressure relief valve 206 is provided on the inner wall of the end of the breathing channel 205 away from the piston body 201; when the negative pressure in the first cavity 403 and the second cavity 404 is too large, the pressure relief valve 206 is opened, and the outside atmosphere enters the first cavity 403 and the second cavity 404 through the breathing channel 205, increasing the air pressure in the first cavity 403 and the second cavity 404, thereby avoiding excessive negative pressure in the first cavity 403 and the second cavity 404, and extracting gastric juice too quickly, causing discomfort to the patient.

[0055] like Figure 2 As shown, further, this embodiment also includes the following technical solutions: a second liquid inlet 207 is arranged on the side wall of the containing body 401, and along the axial direction of the containing body 401, the second liquid inlet 207 is located between the piston body 201 and the guide body 402; it also includes a second liquid inlet pipe 208, a second flushing pipe 209 and a secondary three-way valve 210, wherein the second liquid inlet pipe 208, the second flushing pipe 209 and the second liquid inlet 207 are respectively connected to the three valve ports of the secondary three-way valve 210.

[0056] The technical principle and technical effect of this solution are similar to those of the first liquid inlet pipe 102, the first flushing pipe 103 and the primary three-way valve 104 in Example 1. In order to facilitate the flushing of the second flushing pipe 209, they are not elaborated here.

[0057] like Figure 2 As shown, further, this embodiment also includes the following technical solutions: the surfaces of the container 401 and the guide body 402 have a plurality of scale lines along the axis of the container 401, and the volume represented by two adjacent scale lines is 10ML. This embodiment is consistent with Example 1, and refines the scale on the surface of the gastrointestinal decompression device, so that the staff can read more accurately.

[0058] When the gastrointestinal decompression device of this embodiment is used, the discharge switch valve is closed, and the medical staff holds the handle 204 and drives the piston body 201 to move upward through the connecting rod 202, so that the first cavity 403 and the second cavity 404 generate negative pressure, and the patient's gastric fluid is sucked into the first cavity 403 and the second cavity 404 through the second liquid inlet pipe 208 and the second liquid inlet port 207; the volume of the sucked gastric fluid is read through the scale lines on the surface of the containing body 401 and the guide body 402; when the gastrointestinal decompression device is full of gastric fluid, the discharge switch valve is opened to discharge the fluid through the discharge port 405.

[0059] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
