Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a subcutaneous emphysema venting device with an exhaust valve. Background Technology

[0002] Subcutaneous emphysema is a clinical symptom that occurs when air enters the soft tissue beneath the skin. It can occur anywhere in the body, but after lung surgery, subcutaneous emphysema usually occurs in the chest, neck, and face. In severe cases, it can cause symptoms such as difficulty opening the eyes and difficulty breathing. These symptoms reduce patient comfort and affect patient satisfaction with treatment.

[0003] Subcutaneous emphysema is a common postoperative complication of thoracic surgery. When only a small amount of subcutaneous emphysema is present, conservative treatment is generally used, allowing the emphysema to resolve on its own. However, some patients with frequent coughing may develop severe, generalized subcutaneous emphysema, leading to respiratory distress and significantly impacting their quality of life. For these patients, a small incision might be made to manually expel the gas, but this requires frequent manual expulsion. This not only increases the workload of medical staff but also increases the risk of backflow or leakage due to improper operation, raising the risk of infection. Therefore, a subcutaneous emphysema drainage device with an exhaust valve is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that require manual expulsion of gas, which necessitates frequent manual operations. This not only increases the workload of medical staff but also easily leads to gas backflow or leakage due to improper operation, increasing the risk of infection. Therefore, this invention proposes a subcutaneous emphysema venting device with an exhaust valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A subcutaneous emphysema decompression device with an exhaust valve includes a needle with multiple air holes around its circumference. A first connecting tube is fixedly installed at one end of the needle. An intermediate tube is fixedly connected to the end of the first connecting tube away from the needle. A second connecting tube is fixedly connected to the end of the intermediate tube away from the first connecting tube. An air collection bag is fixedly connected to one end of the second connecting tube. Both the first and second connecting tubes are flexible tubes.

[0007] A gasket is provided inside the intermediate tube, and the gasket is located on one side of the first connecting tube. A first spring is fixedly connected between the gasket and the inner wall of one end of the intermediate tube.

[0008] A control component is disposed around the circumference of the first connecting pipe for controlling the gas output efficiency.

[0009] As a further embodiment of this utility model, the control component includes a mounting shell, which is slidably fitted around the circumference of the first connecting tube. Inclined slide rails are provided on both sides of the mounting shell, and a pressure roller is slidably connected between the two slide rails, with the pressure roller abutting against the first connecting tube.

[0010] As a further embodiment of this utility model, a limiting sleeve is fixedly connected to the inner wall of one end of the gas collecting bag, and a sealing ball is provided inside the limiting sleeve. The sealing ball is located on one side of the second connecting pipe, and a second spring is fixed between the sealing ball and the limiting sleeve.

[0011] As a further embodiment of this invention, a communicating pressure airbag is fixedly installed around the circumference of the second connecting tube.

[0012] As a further embodiment of this invention, a hanging ring is fixedly connected to the end of the air collecting bag away from the pressing air bladder.

[0013] As a further improvement of this invention, the gas collection bag is transparent and contains physiological saline solution.

[0014] In this application, during use, the gas collection bag is hung on an IV stand or other frame via a hanging ring. The pressure roller is moved to squeeze the first connecting tube, causing it to close. Then, the needle is inserted into the subcutaneous emphysema area and fixed to the emphysema area with a dressing. When venting, the pressure roller is moved to open the first connecting tube, allowing gas to enter the intermediate tube through the first connecting tube, which in turn pushes open the gasket. The gas then enters the gas collection bag through the second connecting tube and is collected. Simultaneously, the venting speed can be judged by observing the air bubbles in the gas collection bag, avoiding discomfort caused by excessively rapid venting. After the gas is vented, the gasket and sealing ball reset under the action of the first and second springs, respectively, to prevent air backflow. For patients with severe gas accumulation and poor venting, the air bag can be manually pressed. Utilizing the automatic reset feature of the air bag, the gas in the emphysema can be vented more quickly, improving the flexibility of use.

[0015] Beneficial effects: In this utility model, the subcutaneous emphysema venting device with venting valve, through the setting of the middle tube, allows the first connecting tube to be blocked by the gasket, ensuring venting while preventing air backflow and improving the safety of use.

[0016] In this utility model, the subcutaneous emphysema decompression device with an exhaust valve is designed to release gas from emphysema more quickly by installing a pressure airbag around the circumference of the second connecting tube and manually pressing the pressure airbag, taking advantage of the airbag's automatic reset feature. This improves the flexibility of use.

[0017] In this invention, the gasket can be used to shield the first connecting pipe, ensuring exhaust while preventing air backflow and improving safety. At the same time, by manually pressing the airbag, the airbag automatically resets, allowing the bloated gas to be expelled more quickly, thus improving the flexibility of use.

A first spring 12 is fixedly connected between the gasket 11 and the inner wall of one end of the intermediate tube 6. Gas enters the intermediate tube 6 through the first connecting tube 3, thereby pushing the gasket 11 open. Then, it enters the gas collection bag 8 through the second connecting tube 7 and is collected. After the gas is discharged, the gasket 11 can be reset to prevent air backflow.

[0025] A control component is provided, which is located around the circumference of the first connecting pipe 3 to control the air output efficiency.

The sealing ball 14 is located on one side of the second connecting pipe 7. A second spring 15 is fixed between the sealing ball 14 and the limiting sleeve 13. The sealing ball 14 further prevents air backflow.

[0029] It should be noted that a connected compression airbag 9 is fixedly installed around the circumference of the second connecting tube 7. By manually pressing the compression airbag 9, the automatic reset feature of the compression airbag 9 is utilized to allow the emphysematous gas to be discharged more quickly, thus improving the flexibility of use.

[0030] In this invention, a hanging ring 10 is fixedly connected to the end of the gas collecting bag 8 away from the pressing airbag 9, and the hanging ring 10 facilitates the fixation of the gas collecting bag 8.

[0031] In particular, the gas collection bag 8 is transparent and contains saline solution, which can generate bubbles when the gas is released, making it easy for people to observe.
