Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a gastrointestinal decompression negative pressure box. Background Art

[0002] Gastrointestinal decompression involves inserting a gastric tube through the mouth or nose, which, through the negative pressure and siphon effect, draws gastric contents out of the patient's body. This method draws out gas or fluid from the gastrointestinal tract, reducing pressure and distension. It is commonly used preoperatively to reduce flatulence during gastrointestinal surgery and postoperatively to remove gas and gastric contents, alleviate abdominal distension, reduce suture tension and wound pain, promote wound healing, improve blood circulation in the gastrointestinal wall, and promote the recovery of digestive function.

[0003] Currently, most hospitals use a cylindrical negative pressure box for gastrointestinal decompression. The negative pressure inside the box, combined with a gastric tube, extracts gastric fluid from the patient's body. While this method is simple to operate, it still has drawbacks. The box needs to be secured to the patient's clothing with a pin. If there is too much gastric fluid inside, the box can easily fall off, causing the box to disconnect from the gastric tube. Furthermore, when performing multiple gastric fluid extractions, the gastric tube must be left in place, and only the box can be replaced. This process can produce an odor, and excessive gastric fluid extraction can cause leakage. After gastrointestinal decompression, some patients experience excessive gastric fluid extraction, which can affect normal gastrointestinal function. Therefore, the extracted gastric fluid must be reinfused back into the stomach. Before reinfusion, the gastric fluid must be filtered and a sample collected. Medical staff typically filter the sample using sterile gauze before sampling and reinfusion. This entire process is not only time-consuming, but also contaminates the reinfused gastric fluid during prolonged operation. Utility Model Content

[0004] In response to the above problems, the present invention designs a gastrointestinal decompression negative pressure box, which prevents the gastric tube from falling off during the extraction of gastric fluid by installing an anti-trip buckle at the connection between the gastric tube and the negative pressure box, and connects fixing clips on both sides of the box body to effectively fix the box body on the patient's clothing to prevent the device from falling off due to excessive extraction of gastric fluid; by installing a first one-way valve in the liquid inlet pipe in conjunction with a second torsion spring, the gastric fluid extracted into the box body is prevented from leaking and being contaminated by odor when the gastric tube is disassembled and assembled; in order to facilitate the reinfusion of gastric fluid, sterile gauze is installed inside the box body, and the gastric fluid can be filtered by the sterile gauze when it is discharged, so that the gastric fluid meets the reinfusion requirements.

[0005] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions: A gastrointestinal decompression negative pressure box, comprising a box body;

[0006] The top and rear of the box body are respectively equipped with a liquid inlet pipe and an air extraction pipe, the liquid inlet pipe is sleeved with a gastric tube joint, the gastric tube joint and the liquid inlet pipe sleeve are an outwardly protruding ring, the gastric tube joint is connected to the gastric tube, and an anti-slip buckle is installed on the periphery of the gastric tube joint and the liquid inlet pipe sleeve;

[0007] A liquid outlet pipe is installed at the lower front side of the box body, a rubber stopper is installed on the liquid outlet pipe, fixing belts are installed on the left and right sides of the box body, and the other ends of the fixing belts are connected to fixing clips. Sterile gauze is installed obliquely inside the box body, and the sterile gauze divides the interior of the box body into an upper chamber and a lower chamber, and the lower chamber is connected to the liquid outlet pipe;

[0008] A first one-way valve for flowing downward is installed in the liquid inlet pipe, and a second one-way valve for flowing upward is installed in the air extraction pipe.

[0009] Furthermore, a heparin cap is installed on the air extraction tube;

[0010] Furthermore, the anti-drop buckle is formed by connecting two upper and lower notched rings, the inner diameter of the notched ring is equal to the inner diameter of the gastric tube connector and the liquid inlet tube, and the distance between the upper and lower notched rings is equal to the thickness of the two convex rings at the connection between the gastric tube connector and the liquid inlet tube, so that the anti-drop buckle can prevent the gastric tube connector from loosening after installation;

[0011] Furthermore, both sides of the end of the stomach tube connector are protruding, so that after the stomach tube connector is sleeved with the liquid inlet tube, the single flap can be pushed open downwards.

[0012] Beneficial effects of the utility model:

[0013] The utility model can prevent the liquid inlet tube and the gastric tube joint from falling off when extracting gastric fluid by means of an anti-tripping buckle installed at the connection between the gastric tube joint and the liquid inlet tube. A first one-way valve installed in the liquid inlet tube can cooperate with the gastric tube joint to open when the gastric tube joint is connected, and can be closed after the gastric fluid is extracted, so as to prevent gastric fluid and odor from leaking out of the box body. When the gastric fluid is reinfused, the gastric fluid will be filtered from the upper chamber through the sterile gauze to the lower chamber before being discharged through the liquid outlet tube, and the filtered gastric fluid will then flow out from the liquid outlet tube. The fixing clips installed on both sides of the box body can fix the box body to the patient's clothes through the action of the first torsion spring, so as to prevent the box body from slipping after excessive gastric fluid is extracted.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] Example 1

[0024] See Figures 1 to 5 As shown, a gastrointestinal decompression negative pressure box is proposed, comprising a box body 1;

[0025] The box body 1 is as follows Figure 1 As shown, it is cylindrical, and the side is made of transparent soft plastic material. The volume scale is engraved on the side of the box body, and the gastric fluid volume in the box body can be observed in real time. The front and back of the top of the box body 1 are respectively installed with a liquid inlet tube 4 and an air extraction tube 7. The air extraction tube 7 is installed with a heparin cap 701. The liquid inlet tube 4 is sleeved with a gastric tube connector 5. The gastric tube connector 5 and the liquid inlet tube 4 are sleeved at the outer side of the sleeve, forming two convex rings, and the outer diameter and thickness of the upper and lower convex rings are the same. The periphery of the gastric tube connector 5 and the liquid inlet tube 4 is installed as shown. Figure 2The plastic anti-trip buckle 6 shown is formed by connecting two upper and lower notched rings 601. The inner diameter of the notched ring 601 is equal to the inner diameter of the gastric tube connector 5 and the liquid inlet tube 4. The distance between the upper and lower notched rings 601 is equal to the thickness of the two convex rings at the socket joint of the gastric tube connector 5 and the liquid inlet tube 4. The anti-trip buckle 6 uses its own elasticity to clamp the gastric tube connector 5 and the liquid inlet tube 4 at the socket joint to lock the gastric tube connector 5 and the liquid inlet tube 4 to prevent the gastric tube connector 5 from falling off. A liquid outlet pipe 2 is installed at the lower front side of the box body 1, and a rubber stopper 201 is installed on the liquid outlet pipe 2. The rubber stopper 201 is threadedly connected to the liquid outlet pipe 2 and can be manually opened when gastric fluid needs to be re-infused, and sampling is performed through the liquid outlet pipe. A sterile gauze 8 is installed inside the box body 1 corresponding to the liquid outlet pipe 2, as shown in FIG. Figure 4 As shown, sterile gauze 8 is installed obliquely inside the box body 1, dividing the box body 1 into an upper chamber 12 and a lower chamber 11, wherein the lower chamber is connected to the liquid outlet pipe 2, and fixing belts 301 are installed on the left and right sides of the box body 1, and the other end of the fixing belt 301 is connected to a fixing clip 3, as shown in FIG. Figure 3 As shown, a first torsion spring 302 is installed inside the fixing clip 3, which can effectively fix the box body 1 on the clothing; Figure 5 As shown, a first one-way valve 9 is symmetrically installed in the liquid inlet tube 4. The first one-way valve 9 includes two symmetrical semicircular membranes, which are respectively connected to the inner wall of the liquid inlet tube 4 through a rotating shaft. A second torsion spring 901 is provided on the rotating shaft. The second torsion spring 901 keeps the first one-way valve 9 in a normally closed state and can be pushed open when the gastric tube connector 5 is connected.

[0026] When using this device to extract gastric fluid from a patient, remove the heparin cap 701, use a vacuum pump or syringe to connect the vacuum tube 7 to draw the inside of the box body 1 into a negative pressure state, and maintain the inside of the box body in a negative pressure state under the action of the second one-way valve 10, and then start the operation. First, connect the gastric tube connector 5 of this device to the gastric tube inserted into the patient's body in advance, and then clamp the fixing clips 3 on both sides of the box body 1 on the patient's clothes to fix the device, and connect the gastric tube connector 5 with the liquid inlet tube 4. After the connection is completed, use the anti-drop buckle 6 to clamp the gastric tube connector 5 and the liquid inlet tube 4. When the gastric tube connector 5 contacts the first one-way valve 9, it will push the first one-way valve 9 downward, so that the gastric tube and The liquid inlet tube 4 is connected. At this time, due to the negative pressure state in the box body 1, gastric juice will enter the box body 1 along with the gastric tube. When the gastric juice extraction is completed, the anti-trip buckle 6 is removed and the gastric tube connector 5 is pulled out. At this time, the first one-way valve 9 returns to the closed state, preventing the gastric juice and odor in the box body 1 from leaking. In order to further remove the odor, the liquid outlet tube is plugged with a rubber plug with a carbon sheet; when sampling is needed, the rubber plug 201 on the liquid outlet tube 2 can be opened to sample. When part of the gastric juice needs to be returned, the rubber plug 201 is opened and the gastric tube is connected. The gastric fluid discharged from the liquid outlet tube 2 is filtered through the sterile gauze 8 between the upper chamber 12 and the lower chamber 11, which greatly reduces the amount of operation for medical staff.
