Problems solved by technology

However, there are a lot of gaps inside the existing needle injection connector, and the airtight effect is not good, resulting in a large amount of air or medicine remaining in it, and medicine and blood are not properly flowed back and remain in the other inside, when the next injection When injecting medicine, air or residual medicine will be pumped into the patient's body in a positive pressure manner, resulting in improper expansion of blood vessels and causing pain to the patient. When the injection is completed and the syringe is withdrawn, the blood and medicine will also flow back in a negative pressure manner. Back into the injection connector, such reciprocating operation will generate air backflow pressure, causing the patient to bear the pain caused by the positive pressure expansion of the blood vessel when injecting the medicine for no reason. possible superinfection

Embodiment Construction

[0056] see Figure 1 to Figure 5 , the present invention provides a needle-free connector module 100 for connecting an injection syringe (such as Image 6 ) and a guide tube (such as Image 6 ), the needle-free connector module 100 includes a needle-free nut 10 , an elastic valve 20 , an elastic bracket 30 assembled on the elastic valve 20 and a dosing cap 40 . like figure 1 and Figure 5 As shown, the needle-free nut 10 and the dosing cap 40 are assembled with each other, and the elastic valve 20 and the elastic bracket 30 are both accommodated between the needle-free nut 10 and the dosing cap 40; wherein, the elastic valve 20 has a The upper valve body 201 and a hollow lower valve body 202, because the upper valve body 201 has a longitudinal slit SL, and the slit SL has a closed state and a stretched state, when the elastic valve 20 is not subjected to external force and maintains the preset When shaped, the slit SL can be in an airtight closed state, so it can effective...

Abstract

The invention provides a pin-free connector module and a system thereof. The pin-free connector module mainly comprises a pin-free screw cap, an elastic valve, an elastic support assembled on the elastic valve and a medicine adding cap. The medicine adding cap is provided with a hollow cavity and is connected with the pin-free screw cap, and the elastic valve and the elastic support are held in the hollow cavity; the elastic valve is provided with an upper valve body and a hollow lower valve body, and a longitudinal narrow seam is formed in the upper valve body; and the elastic support is provided with a support body and a plurality of elastic supporting ribs. According to the pin-free connector module and the system thereof, when the elastic valve is free of external force and maintains a prearranged shape, the narrow seam in the upper valve body is under an airtight seal state, and external air or drugs can be effectively prevented from entering the module and the system; and additionally, the elastic valve is provided with the elastic support, deformation and restoration positioning of the elastic valve can be effectively controlled.

Description

technical field [0001] The invention relates to a needle-free connector module and a system thereof, in particular to a needle-free connector module and a system for medical tools, blood transfusion or infusion. Background technique [0002] Existing syringes and syringes are common medicament administration devices. However, syringes and syringes are dangerous, so they need to be recycled, resulting in increased medical costs. In addition, because the needle is a sharp structure, when the medical personnel use the existing needle syringe, they may accidentally be stabbed by the needle, and if the needle is not clean, it will cause infection. The dosing tube that can be filled with medicine can avoid the chance of medical staff being infected and increase the safety of use, and the used needle must be discarded, which increases the cost burden. Later, a needle-free injection connector and a needle-free syringe were developed to administer medicine. This kind of device has l...
