Description

Technical Field

[0001] The invention relates to the technical field of three-cavity two-balloon tubes, and in particular to an anti-leakage pressure measuring device for three-cavity two-balloon tubes. Background Art

[0002] The three-chamber two-balloon tube is a medical device that uses compression to stop bleeding. It is mainly used to treat severe upper gastrointestinal bleeding, especially esophageal varicose vein rupture and bleeding. It is mainly composed of three cavities and two balloons. The three cavities are used for gastric tubes, gastric balloon inflation tubes and esophageal balloon inflation tubes, respectively, while the two balloons are gastric balloons and esophageal balloons, attached to one end of the three-chamber tube. The working principle of the three-chamber two-balloon tube is based on the balloon compression principle. After the tube is inserted into the stomach and esophagus, air is injected into the gastric balloon to expand and compress the gastric fundus; at the same time, air is injected into the esophageal balloon to expand and compress the lower esophagus. This compression can directly compress the bleeding veins, thereby achieving the purpose of stopping bleeding. However, when the existing three-chamber two-balloon tube is used for leak detection, the operation process is relatively cumbersome and the anti-leakage effect is not ideal.

[0048] Embodiment 1

[0049] like Figures 1 to 3 As shown, the present application is a leakage-proof pressure measuring device for a three-chamber two-balloon tube, comprising a connecting component 100, a transmission component 200 and a pressing component 300;

[0050] The connecting assembly 100 includes a handle 110, a screw rod 120, an upper fixing ring 130, a vertical plate 140, a lower fixing ring 150, and a spring 160;

[0051] The handle 110 is a rectangular body, and a screw 120 is fixedly connected to the center of the bottom of the handle 110;

[0052] The screw rod 120 is a cylindrical rod, and a cavity is formed inside the screw rod 120 . A pressing assembly 300 is disposed at the bottom end of the screw rod 120 .

[0053] An upper fixing ring 130 is inserted and connected to the outer side of the middle portion of the screw rod 120;

[0054] The upper fixing ring 130 is an arch-shaped body, and the front and rear parts of the bottom end of the upper fixing ring 130 are fixedly connected with vertical plates 140;

[0055] The vertical plate 140 is a rectangular body, and the bottom ends of the two vertical plates 140 are fixedly connected to a lower fixing ring 150;

[0056] The lower fixing ring 150 is an arch-shaped body, and a transmission component 200 is arranged on the inner surface of the lower fixing ring 150;

[0057] The pressing assembly includes a pressing head 310;

[0058] The top of the pressing head 310 is provided with a through mounting hole, and the bottom end of the screw rod 120 is threadedly connected in the mounting hole of the pressing head 310. The pressing head 310 is a rectangular body;

[0059] The pressing head 310 is made of stainless steel, has high strength, high hardness and good wear resistance, and can withstand greater pressure and wear;

[0060] The handle 110, the screw rod 120, the pressing head 310, the elastic pad 320, and the air delivery pipe 330 are all coaxially arranged;

[0061] The transmission assembly 200 includes a connecting tube 210, an air source 220, a first bag 230, a fixing tube 240, a second bag 250, a three-chamber two-bag airway 260, and a tube plug 270;

[0062] The inner wall of the lower fixing ring 150 is fixedly connected to the outer surface of the connecting pipe 210;

[0063] The connecting tube 210 is a cylindrical tube, and one end of the connecting tube 210 is fixedly connected to a gas source 220;

[0064] The gas source 220 is an ellipsoid, and the other end of the connecting tube 210 is fixedly connected to the first bag 230;

[0065] The first capsule 230 is an ellipsoid, and one end of the first capsule 230 away from the connecting tube 210 is fixedly connected to the fixing tube 240;

[0066] The fixing tube 240 is a cylindrical body, and one end of the fixing tube 240 away from the first capsule 230 is fixedly connected to the second capsule 250;

[0067] The second balloon 250 is an ellipsoid, and one end of the second balloon 250 away from the fixing tube 240 is fixedly connected to a three-chamber two-balloon trachea 260;

[0068] The three-chamber two-balloon trachea 260 is an arch-shaped tube, and both ends of the three-chamber two-balloon trachea 260 are sleeved with tube plugs 270, and the tube plugs 270 are cylindrical;

[0069] The lower fixing ring 150 and the upper fixing ring 130 have the same structure and are symmetrically distributed up and down.

[0070] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0071] The pressing head 310 of the pressing assembly 300 is rectangular, which can provide a better pressing effect. When the rectangular pressing head 310 is pressed on the connecting tube 210, due to the advantages of its shape and contact area, it can distribute the pressure more evenly, so that the seal between the connecting tube 210 and the three-chamber two-bag trachea 260 is tighter, thereby effectively preventing air leakage. The rectangular shape increases the contact area between the pressing head 310 and the connecting tube 210, thereby improving the sealing effect. The rectangular pressing head 310 can distribute the pressure more evenly when pressing, avoiding the situation where the local pressure is too large or too small, and further improving the sealing performance. Yes, the rectangular shape makes the pressing head 310 more stable during the pressing process, and it is not easy to shake or deflect, thereby ensuring the reliability of the seal. The rectangular pressing head 310 makes the force more uniform during the pressing process, reducing the risk of air leakage due to unstable pressing. The device is relatively easy to use. Medical staff only need to press the pressing head 310 on the connecting tube 210 to complete the sealing operation without complicated operating steps. The device has good durability and can maintain a stable sealing effect for a long time. The device is suitable for three-chamber two-bag trachea 260 of different specifications and models, and has strong versatility and adaptability.

[0072] Embodiment 2

[0073] In order to further improve the applicability and convenience of the pressing component of the anti-leakage pressure measuring device for a three-chamber two-balloon tube of the present application, the pressing component is optimized and improved in the embodiment of the present application, specifically:

[0074] like Figure 4 As shown, the pressing assembly further includes an elastic pad 320;

[0075] The bottom of the pressing head 310 is fixedly connected to an elastic pad 320, the elastic pad 320 is a rectangular body, and both sides of the bottom of the elastic pad 320 in the length direction and the width direction are fixedly connected to first protrusions 321;

[0076] The first protrusion 321 is a hemispherical body, and a second protrusion 322 is arranged inside the first protrusion 321. There are 12 to 16 first protrusions 321.

[0077] The second protrusion 322 is fixedly connected to the bottom of the elastic pad 320 and has a gap with the first protrusion 321. The second protrusion 322 is a rectangular body, and there are 6-8 second protrusions 322.

[0078] The elastic pad 320 is made of rubber material, has excellent elasticity and wear resistance, can effectively reduce impact force, absorb vibration, and thus protect mechanical equipment from damage.

[0079] The elastic pad 320 is located between the pressing head 310 and the connecting tube 210. Long-term use of the pressing head 310 for pressing will cause damage to the connecting tube 210. The elastic pad 320 can buffer the direct pressure of the pressing head 310 on the connecting tube 210. By absorbing and dispersing pressure, the elastic pad 320 effectively reduces the wear and damage of the connecting tube 210 caused by long-term pressing. The elastic pad 320 itself has a certain elasticity and sealing property, and can form a preliminary sealing contact with the connecting tube 210 in an uninflated state, providing a basis for the subsequent raised inflation seal. The circular first protrusion 321 and the rectangular second protrusion 322 not only increase the contact area with the connecting tube 210, but also through their special shape and layout, more tiny contact points can be formed after inflation, thereby significantly increasing friction and preventing the connecting tube 210 from sliding or leaking during the pressing process. The first protrusion 321 and the second protrusion 322 are capsules and can be inflated, and the degree of inflation can be adjusted according to actual needs. When the amount of inflation is small, the protrusion provides moderate sealing and friction; when the amount of inflation is large, the protrusion can fit the connecting tube 210 more closely, forming a stronger sealing effect. By adjusting the inflation degree of the protrusion, the rigidity of the pressing component 300 can be maintained while ensuring the sealing. The balance between rigidity and sealing enables the pressing component 300 to be firmly fixed on the connecting tube 210 without damaging the connecting tube 210 due to overtightening. The combined use of the elastic pad 320 and the protrusion structure achieves an efficient and reliable sealing effect through multi-point contact and adjustable inflation degree, effectively preventing the occurrence of air leakage. The buffering effect of the elastic pad 320 and the adjustability of the protrusion structure jointly reduce the damage to the connecting tube 210 and extend its service life. The inflation degree of the protrusion can be adjusted according to actual conditions, so that the pressing component 300 can adapt to connecting tubes 210 of different shapes and sizes, improving the flexibility and adaptability of operation.

[0080] Embodiment 3

[0081] In order to further improve the applicability and convenience of the pressing component of the anti-leakage pressure measuring device for a three-chamber two-balloon tube of the present application, the pressing component is further optimized and improved in the embodiment of the present application, specifically:

[0082] like Figure 5 As shown, the pressing assembly further includes an air delivery pipe 330;

[0083] The air delivery pipe 330 is disposed in the cavity of the screw 120 . The air delivery pipe 330 is a cylindrical tube. One end of the air delivery pipe 330 is at the top center of the handle 110 , and the other end of the air delivery pipe 330 is at the top of the elastic pad 320 .

[0084] The gas pipe 330 is made of medical-grade silicone, which is soft, corrosion-resistant and high-temperature-resistant, and can ensure the hygiene and safety of the pipeline.

[0085] The air supply pipe 330 can inflate the elastic pad 320 and the protruding structure so that they fit tightly against the connecting pipe 210, effectively reducing the possibility of gas leakage. The expanded elastic pad 320 and the protruding structure can fill the tiny gaps on the surface of the connecting pipe 210 to form a tighter sealing layer. After the air supply pipe 330 is inflated, the expansion of the elastic pad 320 and the protruding structure increases the contact area and friction with the connecting pipe 210, making the connection more stable. The stable connection can resist external pressure or vibration and maintain the stability of the device during long-term use. Reducing air leakage means fewer treatment interruptions and higher treatment efficiency, which helps to improve the overall treatment effect of the patient. Effective air leakage prevention reduces the patient's discomfort caused by air leakage and improves the comfort and tolerance of treatment. The air supply pipe 330 enables medical staff to easily perform inflation and deflation operations, simplifies the use process, and clear operating instructions and intuitive design help reduce operating errors and improve use efficiency.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
