Description

An auxiliary device for clinical anesthesiology

technical field

The invention relates to the technical field of clinical anesthesia, in particular to an auxiliary device for clinical anesthesia.

Background technique

After the patient is diagnosed in the hospital, some patients need to be treated by surgery in the clinic. Before the surgery, the patient needs to be anesthetized, and there are many methods of anesthesia. Some patients need to be intubated before anesthesia, which is about to be fixed. The tube is inserted from the patient's mouth, and then the external instruments are connected to the fixed tube to ensure the safety of the patient. In order to facilitate the installation of the fixed tube, the patient's mouth needs to be supported, so it is necessary to use a certain auxiliary mouth to continue to open. open tool.

However, some existing auxiliary devices for clinical anesthesiology have the following problems:

1. The use is not convenient enough. When some existing auxiliary devices for clinical anesthesiology support the patient's mouth, the auxiliary support device can fix the patient's mouth by rotating and other methods. After adjustment, an additional locking step is required. When disassembling the support device, the locking device also needs to be released, which increases the workload of medical staff. At the same time, these steps require a relatively long time, thereby reducing the The treatment efficiency of the patient, and some auxiliary fixation devices support the oral cavity through multiple sets of gear transmissions, which not only increases the weight and cost of the entire device, but also lengthens the movement stroke of the entire device, thereby making the entire device longer. is not convenient enough to use;

2. Poor functionality. Some existing auxiliary devices for clinical anesthesiology only serve to support the patient's mouth and facilitate intubation. For the contact part between the entire device and the teeth, when the teeth are in contact with the support point, a certain amount of secretion will be secreted. When the patient's mouth is opened, the saliva is difficult to swallow. If the saliva accumulates too much, it is easy for the patient to choke, which in turn easily causes secondary injury to the patient, and also delays the process of the operation. Some support devices do not effectively suppress the patient's tongue. When the tube is inserted into the patient's body, there will be a certain degree of discomfort. The patient will subconsciously use the tip of the tongue to push the tube, so that the tube can easily be inserted into the patient's throat. The part shakes, which easily causes discomfort to the patient, and some tongue-suppressing devices tend to become numb after a long time of pressing, and the existing support devices cannot effectively solve the problem, so the function of the whole device is poor.

Therefore, we propose an auxiliary device for clinical anesthesiology in order to solve the problems mentioned above.
