Embodiment

[0016] The chest drainage tube we used is silicone rubber, about 20 cm long, with five side holes of 0.2 cm × 0.2 cm in length at the top, marked with scales to indicate the depth of the chest tube placement. The surface is coated with paraffin oil, which is usually dry and becomes smooth when it meets water. The tail end is connected with the inlet of the manual negative pressure device. The manual negative pressure device is made of ordinary plastic, oval in shape and about 10cm in length, and can produce With a pressure of about 5-10cm water column, it can not only be used as a negative pressure device for negative pressure drainage, but also can be used as a positive pressure device for thoracic blood reinfusion, which can speed up the filtration speed of blood and the reinfusion speed of thoracic blood , the outlet of the negative pressure device is connected to the inlet of the drainage bag. The drainage bag is divided into an outer bag and two inner bags. The size of the...

Abstract

The invention relates to a portable hemopneumothorax treatment device with manual vacuum, which belongs to the technical field of medicinal surgical instruments. The portable hemopneumothorax treatment device is characterized in that a cylindrical open long pipe made of silicon rubber and provided with a coating outside is provided with an opening on the pipe side wall near one open end and is provided with a bottleneck reducing opening at the other end, a film is covered outside the reducing opening; the open head part of a lambda-shaped tee pipe and the bottleneck reducing opening extend into an ellipsoidal air bag; two symmetrical branch pipes of the tee pipe are respectively inserted into a water sealing bag and a large mesh small drainage bag; the two small bags are placed in a firstinner bag together; the first inner bag is nested with a second inner bag, the second inner bag is placed in an outer bag; and the bottom of the outer bag is provided with an output hole and the top is provided with a vent hole. Because a thorax drainage pipe, a manual vacuum device and a thorax drainage blood storage bag are combined to form the portable hemopneumothorax treatment device, a patient can be treated to meet emergency on site by using the treatment device, thereby meeting the site emergency demands and solving various practical problems in the hemopneumothorax treatment on a wound site.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, more precisely, it relates to a medical instrument for the treatment of pneumothorax, which is used at the wound site. Background technique [0002] More than 80% of patients with chest trauma are accompanied by pneumothorax. At present, closed thoracic drainage is the main treatment for traumatic pneumothorax. Due to the large volume of the existing closed thoracic drainage device, it is easily damaged during transportation, and the drainage tube needs to be sealed with water. And it is required to be lower than 50cm of the body, so it is not suitable for on-site first aid and transfer, and it often takes a certain time for the injured site to reach the hospital. In addition, there is often a lack of blood source for the trauma site, and timely and effective anti-shock cannot be carried out for patients with massive bleeding. This will inevitably lead to the death of some wo...
