Description

One-piece closed chest drainage device

technical field

The utility model belongs to the field of medical devices, in particular to an integrated thoracic closed drainage device used for on-site first aid of pneumothorax after chest trauma. The device has a simple structure and is easy to carry.

Background technique

Thoracic trauma is a trauma with a high incidence rate in wars, natural disasters and accidents. According to statistics, among the 150,000 cases of trauma-related deaths in the United States every year, thoracic trauma-related deaths account for 25%. The applicant participated in the 5.12 Sichuan Earthquake Relief. According to the statistics of the medical institution, 10% of the wounded who were delivered had chest trauma. Thoracic trauma mainly includes rib fractures and lung contusions, both of which can cause pneumothorax. Installing closed thoracic drainage is the main first aid measure and treatment for hemopneumothorax. Most patients with chest trauma can be cured after installing closed thoracic drainage, after anti-infection and general supportive treatment. Only a few patients need surgery and ventilator support for further treatment.

Closed thoracic drainage is a simple operation, but whether the operation can be performed in time is the key to the success of emergency rescue. Since the operation involves a variety of equipment and consumables such as surgical instruments, drainage tubes, drainage bottles, connectors, and tubes, which are inconvenient to carry, it is difficult to perform the operation at the emergency scene. Generally, closed chest drainage is performed after the wounded are sent to the hospital or emergency center, resulting in many patients dying on the way to the hospital or emergency center, or causing the patient's condition to worsen.

In China, many manufacturers have continuously improved closed chest drainage tubes and drainage bottles. Change the drainage bottle from glass to a plastic drainage bottle, or change the drainage bottle to a drainage bag, or install a manual negative pressure device on the drainage bag. But above-mentioned these improvements do not fundamentally meet the needs of on-the-spot first aid such as integrated packaging, disposable use, portability, and low cost of thoracic drainage instruments.

In foreign countries, the improvement of closed thoracic drainage devices is mainly that there is a puncture trocar in the first aid kit equipped by American soldiers. The end of the puncture cannula has a one-way valve. After puncturing into the chest cavity, the metal needle core is removed and the plastic sleeve is left The tube can discharge fluid and air in the chest cavity, but the disadvantages of this device are: first, it is not fixed, and it is easy to fall off; second, the caliber is too small, and it is easy to be blocked by blood clots or broken tissues. Therefore, although these above-mentioned improvements have certain advantages, they have not yet reached the desired level.

Contents of the invention

In order to solve the defects or deficiencies of the above-mentioned prior art, the purpose of this utility model is to provide an integrated closed chest drainage device, which is easy to operate, can be used once, and has low economic cost.

In order to achieve the above tasks, the utility model takes the following technical solutions:

An integrated thoracic closed drainage device, comprising a drainage bottle, a connecting tube and a drainage tube, characterized in that the drainage bottle forms an inverted Y-shaped connection with the drainage tube through the connecting tube, and a needle core is arranged inside the drainage tube, Install the restrictor clamp on the connecting pipe.

Another feature of the utility model is that a vent hole with a screw cap is provided on the upper side of the drainage bottle.

There is a positive hole on the top of the drainage tube, two side holes are opened on both sides of the upper end of the drainage tube, and an air bag is arranged under the two side holes. The air bag communicates with the one-way valve under the drainage tube. Thread, the bottom of the drainage tube is also connected with the nut on the vent hole of the drainage bottle through the pulling wire.

The length of the connecting pipe is 1.0-1.5m.

A scale is provided on the outer wall of the drainage tube.

An air injection hole is arranged on the one-way valve.

The external thread at the end of the drainage tube matches the screw cap on the vent hole on the drainage bottle.

Physiological saline is housed in the described drainage bottle.

The integrated thoracic drainage first aid device of the utility model satisfies the operating needs of integrated thoracic drainage equipment in the first aid environment because the drainage bottle, drainage tube and connecting tube are well connected together. At the same time, put this closed chest drainage first aid kit together with a disposable scalpel, plastic tweezers, a sealed bag of iodophor cotton balls, a non-woven surgical drapes, a pair of sterile gloves, and a bag containing 5ml of 2% lidocaine. The syringes and other accessories are packaged together and configured as a one-time closed chest drainage operation kit, which can better meet the convenience of operation and portability during on-site emergency treatment of closed chest drainage surgery, reduce the cost of surgical instruments, and provide medical treatment in emergency situations. Thoracic trauma patients gain time.
