Description

Improved negative pressure suction device

Technical Field

The utility model relates to the technical field of negative pressure suction, in particular to an improved negative pressure suction device.

Background

The negative pressure suction device utilizes the negative pressure suction principle to form negative pressure in the drainage bag, and sucks various body fluids, secretions and secretions containing microorganisms and pathogenic bacteria in various lacunas through the drainage tube, so that the negative pressure suction device is widely used in various clinical departments and is necessary medical equipment in operating rooms, rescue rooms or guardianship rooms and various clinical departments. Especially plays an irreplaceable role in the treatment of critical patients. When the patient is choked due to various reasons such as rescue reflux aspiration, sputum retention, hemoptysis, food aspiration and the like, the patient is always immediately in danger, and the patient is separated from life danger, thereby playing an important role in airway management of trachea cannula and respiratory tract of critical patients. The sputum aspirator is generally installed at the head of a sickbed and is connected with the suction tank through the suction pipeline, and when a patient needs, the sputum aspirator can be connected with the sputum aspirator to perform nursing operations such as sputum aspiration.

The main structure of the negative pressure suction device commonly used in clinic is as follows: the plastic bottle (can body), the collecting bag (bag body and cover body), the hose and the joint, the specification is 3500ml (single bottle), the collecting bag and the hose form an attraction system, the waste liquid is collected by being drained under the action of the drainage catheter inserted into the body, 1) the colors of the fonts of the suction inlet and the suction outlet on the cover body are consistent with the color of the cover body, and the characters are difficult to recognize; and the meaning of the expression is not well distinguished and is difficult to remember.

2) The appearance of the two conical interfaces of the suction inlet and the extraction outlet on the cover body is identical, so that nurses are prone to making mistakes when connecting pipelines, various patients enter the space between the plastic bottle and the bag body, pollution is caused, hospital infection is easy to occur, or negative pressure is insufficient, and rescue is delayed when the sputum is sucked in an emergency.

3) The distance between the suction inlet and the suction outlet of the cover body is too close, and when the bag body leaks air or is not completely opened, drainage liquid is easy to suck back to the central negative pressure.

4) The cover body is not provided with a lifting handle, so that the cover body is inconvenient to move and the used collecting bag is discarded, even the liquid is poured, workers are polluted, and the personal safety of the related workers is endangered;

at present, because the clinically used negative pressure suction device marks unclear and structural problems, when in operation, pipeline connection errors easily occur, so that negative pressure is unstable or disappears, drainage enters a tank body or flows back into a central negative pressure suction device, pollution and even damage of the central negative pressure suction device are easily caused, and the risk of nosocomial infection and occupational exposure is increased. The workload of nurses can be increased, and rescue is delayed when the sputum is sucked in an emergency. For this reason, many utility models have been made and patented with a sign similar to "negative pressure suction device with suck-back prevention function". However, the problems of poor operability, high price, impractical clinic, complex technology and the like are not converted into a device truly used for clinic;
