Embodiment 1

[0049] like figure 1 and Figure 11 As shown, the embodiment is a combined sealing cap 1 for needle-free infusion. The combined sealing cap 1 includes an outer cover 2, an inner cover 3, a joint 4, an elastic sealing sheet 5 and an inner core 6, and the outer cover 2 includes a cover body 7 and The cover base 8 used to cooperate with the mouth of the liquid storage container, the seal connection between the cover base 8 and the cover body 7, the inner cover 3 is arranged in the cover base 8 and tightly matched with the cover base 8, and the inner cover 3 is provided with an outlet The liquid port 9 is provided with a positioning ring 10 around the top of the liquid outlet 9, and the positioning ring 10 is provided with a support 11 that allows the liquid to pass through. The bottom end of the joint 4 cooperates with the positioning ring 10, and the top of the support 11 Press on the bottom surface of the elastic sealing sheet 5, the outer edge of the upper surface of the elas...

Embodiment 2

[0063] The difference between Embodiment 2 and Embodiment 1 is that: the medicine feeding port 25 is arranged on the positioning ring 10 of the liquid outlet 9 .

Embodiment 3

[0065] The difference between embodiment 3 and embodiment 1 is that the drug-dosing sealing structure 26 is the same as the needle-free infusion structure composed of the joint 4 , the elastic sealing sheet 5 , the inner core 6 and the support member 11 .

Abstract

A combined seal cover (1) for needleless infusion. The combined seal cover (1) comprises an outer cover (2), an inner cover (3), a joint (4), an elastic seal piece (5), and an inner core (6). The outer cover (2) comprises a cover body (7) and a cover base (8) used for being fittingly connected to an opening of a liquid storage container. The cover base (8) and the cover body (7) are hermetically connected. The inner cover (3) is disposed in the cover base (8) and is in close fit with the cover base (8). A liquid outlet (9) is disposed on the inner cover (3). A positioning ring (10) is peripherally disposed above the liquid outlet (9). A support piece (11) allowing liquid to pass through is disposed in the positioning ring (10). The bottom end of the joint (4) is fitted to the positioning ring (10). The tip of the support piece (11) presses the bottom of the elastic seal piece (5). The outer edge of the upper surface of the elastic seal piece (5) is in contact fit with the lower surface of an inner step of the joint (4). The inner core (6) used for being fastened with a needleless infusion tube joint (33) and pushing the elastic seal piece (5) to enable liquid to flow out is disposed in the joint (4). The bottom surface of the inner core (6) is in contact fit with the upper surface of the elastic seal piece (5). The combined seal cover (1) avoids rubber chips in an infusion bottle, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to a combined sealing cap for needle-free infusion. Background technique [0002] Human intravenous injection has been widely used in the field of medicine and health in recent years because of its rapid drug effect. The sealing cap is used as the sealing accessory of the infusion bottle or the infusion bag, and its structure and material have also been continuously improved during actual use. In the clinical intravenous administration treatment, it is often necessary to combine multiple drugs, especially the extensive and large-scale application of antibiotics. Repeated puncture of the bottle stopper during the connection of the infusion tube and the process of dissolving and adding drugs will cause the cork particles to enter the drug solution. [0003] Studies have shown that the desquamation rate of rubber stoppers can reach 42.3% when punctured 2 times with a 16-gaug...
