Background
Syringe barrels are common subcutaneous injection use devices that medical personnel insert through the needle portion of the syringe barrel into a patient to administer a medicament.
But the syringe used at the present stage has the syringe part directly exposed, is easy to hurt medical staff, and meanwhile, the present subcutaneous injection process requires the use of a cotton swab to dip in disinfectant for disinfecting the injection part, and the subcutaneous injection process is complicated.
Accordingly, there is a need to provide a telescopic protective injection structure to solve the above-mentioned problems.
Disclosure of utility model
The utility model aims to provide a telescopic protective injection structure.
The utility model realizes the aim through the following technical scheme:
The telescopic protective injection structure comprises an injection needle module, wherein the injection needle module comprises an injection needle main body, a protective sleeve module is arranged corresponding to the injection needle main body, the protective sleeve module comprises a fixed sleeve, and a telescopic protective sleeve is arranged corresponding to the fixed sleeve;
An elastic body arranged in the fixing sleeve supports against the telescopic protective sleeve, the end part of the telescopic protective sleeve is sleeved on the needle tip, and the needle tip is prevented from being exposed to form a protective type needle tip protective sleeve structure;
During injection, the telescopic protective sleeve contacts the skin of a patient, and is inserted into the patient along with the injection needle body to compress the elastomer and retract the telescopic protective sleeve, so that a compressed protective sleeve type injection structure is formed.
Further, a disinfection cushion block is arranged on the telescopic protective sleeve.
Further, the disinfection cushion block is attached to the injection needle main body and is used as a telescopic guide piece of the telescopic protective sleeve.
Further, the elastic body is constituted by a spring.
Furthermore, the disinfection cushion block is composed of disinfection cotton sheets soaked in alcohol, and the disinfection cushion block is used for carrying out uninterrupted disinfection on the extension of the injection needle main body, so that an injection structure for ensuring the disinfection of the injection part is formed.
Furthermore, when injection is not performed, the end part of the telescopic protective sleeve and the needle point part have a protective distance, and the end part of the telescopic protective sleeve is also provided with a sealing isolating film, so that a protective isolating area which is not contacted with external air is formed in the inner area of the protective sleeve module.
Further, a comfortable contact slope for contacting the skin of the patient is also arranged on the end part of the telescopic protective sleeve.
Compared with the prior art, the utility model covers the needle point by the telescopic protective sleeve which is arranged in a telescopic way when the injector is not used, thereby avoiding puncture.
Drawings
Fig. 1 is a schematic diagram of the structure of the present utility model.
FIG. 2 is a second schematic structural view of the present utility model.
Detailed Description
Examples:
Referring to fig. 1-2, the present embodiment shows a telescopic protection type injection structure, which comprises an injection needle module 1, wherein the injection needle module 1 comprises an injection needle main body 11, a protection sleeve module 2 is arranged corresponding to the injection needle main body 11, the protection sleeve module 2 comprises a fixing sleeve 21, and a telescopic protection sleeve 22 is arranged corresponding to the fixing sleeve 21;
The elastic body 3 arranged in the fixed sleeve 21 supports against the telescopic protective sleeve 22, the end part of the telescopic protective sleeve 22 is sleeved on the needle tip 12, and the needle tip is prevented from being exposed to form a protective type needle tip protective sleeve structure;
During injection, the telescopic protective sleeve 22 contacts the skin of a patient, and as the injection needle body 11 is inserted into the patient, the elastic body 3 is compressed, and the telescopic protective sleeve 22 is retracted, so that a compressed protective sleeve injection structure is formed.
The telescopic protective sleeve 22 is provided with a disinfection cushion block 4.
The sterilizing pad 4 is attached to the needle body 11 and serves as a telescopic guide for the telescopic guard 22.
The elastic body 3 is constituted by a spring.
The disinfection cushion block 4 is composed of disinfection cotton sheets soaked in alcohol, and the disinfection cushion block 4 performs uninterrupted disinfection of the extension of the injection needle main body 11 to form an injection structure for ensuring disinfection of injection parts.
When injection is not performed, the end part of the telescopic protective sleeve 22 and the needle tip part 12 have a protective distance 5, and the end part of the telescopic protective sleeve 22 is also provided with a sealing isolating film 6, so that a protective isolating area which is not contacted with external air is formed in the inner area of the protective sleeve module 1.
A comfort contact ramp 23 for contacting the patient's skin is also provided on the end of the telescoping shield 22.
Compared with the prior art, the utility model covers the needle point by the telescopic protective sleeve which is arranged in a telescopic way when the injector is not used, thereby avoiding puncture.
