Problems solved by technology

[0007]The U-shaped frame in this utility model patent can not only protect the needle hard and prevent it from falling from the syringe, but it cannot The needle is sealed and protected, and the needle is easily contaminated by bacteria
[0008]If the above U-shaped frame is used together with a rubber sleeve, although the functions are comprehensive, the opening steps of the syringe need to be rotated to open the U-shaped frame first, and then pull out It is very troublesome to take out the rubber sleeve, and in the emergency medical rescue, this increase in waste of time is very fatal

Embodiment

[0032] Example: as attached Figure 1-4 As shown, a sealing cover used on a syringe includes a protective tube unit 1 whose end is hingedly arranged on the shaft body a of the needle installation tube, and which is arranged in the protective tube unit 1 and sleeved on the needle installation tube b The sealing sleeve unit 2 on the top, the end of the protective tube unit 1 away from the cylinder c is rotated toward the side of the cylinder c to expose the needle d, and the protective tube unit 1 is used to push outward when rotating The sealing sleeve unit 2.

[0033] In the prior art, one end of the needle installation tube b is thick and the other end is thin, the needle head and the common rubber needle sleeve are arranged at the thin end, and the two needle installation tube shafts a form a complete rotating cylinder, ensuring The improved rotary needle cover in the prior art can be effectively rotated to open and close.

[0034] In this embodiment, while the sealing sle...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a sealing cover body used on a needle cylinder. The protective tube unit is hinged to the shaft body of the needle mounting tube, and the sealing sleeve unit sleeving the needle mounting tube is arranged in the protective tube unit, so that the needle head can be protected in a sealed manner and can also be protected from the outside. The invention has the following advantages: firstly, the protective tube unit is hard and is used for blocking and protecting external impact force on the needle head, and the inner side of the sealing sleeve unit is soft and is used for sealing and protecting the needle head, so that the needle head is intact and clean before being used; secondly, the protective tube unit is rotationally opened to expose the needle head, and the sealing sleeve unit can be jacked and bounced off in the early stage of the rotation action, so that the needle head opening operation is completed in one step, and the operation is very fast and efficient; and thirdly, when the sealing cover body is used later, the structural stability is high, the sealing sleeve unit is not prone to falling off accidentally, and the protection pipe unit is not prone to rotating accidentally.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a sealing cover used on a syringe. Background technique [0002] The structure of the syringe part of the syringe mainly includes a cylinder body, a needle installation tube and a needle head, and the needle cover is set on the needle installation tube to protect the needle head. [0003] The most simple type of the existing needle cover is a soft rubber tube with a closed end, which is set on the needle installation tube by the elastic force of its own opening. However, in this way, the needle sleeve is easy to fall off, and even if it does not fall off, the needle head cannot be prevented from being bent or even broken when a relatively large bending force is encountered. [0004] For example, the Chinese utility model patent with the patent announcement number CN 213374427U and the announcement date of 2021.06.08 discloses a new type of anti-infection hyaluronic ac...
