Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, specifically to a medical connecting tube cap. BACKGROUND

[0002] At present, in clinical nursing, medical staff will use negative pressure suction table, waste liquid collecting bag, collecting bag outer tank, medical connecting tube and disposable sputum suction tube for patients to operate sputum suction;

[0003] Among them, the disposable sputum suction tube will directly contact the patient's oral cavity, and has strict aseptic requirements, so it needs to be discarded after each sputum suction operation; The medical connecting tube plays a connecting role between the disposable sputum suction tube and the negative pressure device. Since the medical connecting tube is not actually matched with the disposable sputum suction tube, it needs to be trimmed before use to be inserted into the disposable sputum suction tube, and the medical connecting tube has no strict aseptic requirement. After the medical staff finish operating sputum suction for the patient, they will use sterile normal saline to flush the pipeline, and then place the medical connecting tube on the bedside for standby, that is, the medical connecting tube can be used repeatedly.

[0004] There is no special unified placement method for placing the medical connecting tube on the bedside for standby. If the end part of the medical connecting tube is directly exposed to the environment for placement after flushing, it will be contaminated;

[0005] The countermeasure currently adopted by medical staff is to specially find a syringe with a diameter suitable for the medical connecting tube as an end cap for the medical connecting tube; in this way, the medical connecting tube can be prevented from being contaminated, but a syringe suitable for the medical connecting tube needs to be specially found, and the syringe has no hanging rope. If the standby medical connecting tube needs to be hung, the medical staff need to manually make a hanging rope for the syringe, which greatly affects the efficiency of daily work;

[0006] As for how to prevent the medical connecting tube from being contaminated when it is placed for standby, the patent document with the patent number CN215938459U also proposes a corresponding scheme, which covers the end part of the medical connecting tube with a pollution prevention and disinfection cover special for the medical connecting tube, so as to prevent the medical connecting tube from being exposed to the environment when it is placed for standby, and avoid the situation that the medical connecting tube is contaminated;

[0007] The pollution prevention and disinfection cover in the above patent document is special for the medical connecting tube of the corresponding specification. However, in the practice of sputum suction or sputum suction, the specifications of the medical connecting tube are not unified. For example, in the operation of sputum suction, the medical staff will select the medical connecting tube with the specifications of Fr16~Fr36 according to the actual situation, and the medical connecting tubes with different specifications correspond to different diameters. If the pollution prevention and disinfection cover is of a specific size, a pollution prevention and disinfection cover with a corresponding size needs to be set for each specification of the medical connecting tube;

[0008] Thus, not only do manufacturers need to open molds for anti-pollution and disinfection covers of multiple sizes, increasing production costs, but medical staff may also need to find the appropriate size of the anti-pollution and disinfection cover according to the specifications of the medical connecting tube currently in use, which is too cumbersome to operate.
