Abstract

The utility model discloses a dual-cavity medicine delivery device, provides two injectors which can go without silin bottle and matching liquid, and is characterized in less operation steps, negligible misoperation, short operation time, no pollution when in use, convenience and safe and a little volume integrative dual-cavity medicine delivery device. The utility model comprises two injectors, a fixed support and a sprinkler device, the two injectors arranged on the fixed support in parallel, a three-way valve is arranged among the two injectors and the sprinkler device, a port of the shell of the three-way valve is connected with the cone-head of the injector, the second port is connected with an end of the sprinkler device, the third port is connected with the container.

Description

Integrated two-chamber administrator

Technical field

This utility model relates to a kind of medical apparatus and instruments, and more particularly, this utility model relates to a kind of administrator.

Background technology

Existing administrator is the duplex syringe, this duplex syringe can not mix at the preceding two kinds of solution of ejection if will pack in two syringes two kinds, after the ejection just under the situation of blendable solution, need before this with two other tool syringes two kinds of solution to be prepared, the syringe that uses in the solution reuse process for preparation after the preparation injects the duplex syringe respectively.Such duplex syringe shortcoming in use is: 1, except that the duplex syringe, also need other two tool syringes, and four cillin bottles, packaging volume is excessive, stores transportation and uses inconvenience; 2, how operating procedure is and numerous and diverse, and clinical use is very inconvenient, increased the possibility of maloperation simultaneously; 3, the operating time long, need in advance above preparation half an hour; Easily pollute when 4, operating.

Summary of the invention

This utility model has overcome the deficiency of existing duplex syringe, a kind of cillin bottle and two required tool syringes of dosing of in use need not are provided, operating procedure is few, be difficult for to produce maloperation, pollution-free, the operating time short, simple in structure, convenient and safe, integrated two-chamber administrator that volume is little.

This utility model is realized by following proposal, this utility model comprises two tool syringes, a fixed support and an ejecting device, two tool syringes are parallel to be placed on the fixed support, between an end of two tool syringe coneheads and ejecting device, three-way valve is arranged, a port on the three-way valve housing is connected with the syringe conehead, and second port is connected with an end of ejecting device, and the 3rd port connects container.

Compare with existing duplex syringe, the beneficial effects of the utility model are: when it no longer is to use the duplex syringe owing to there is not corresponding mechanism that various steps such as lysate, medicine, syringe, course of dissolution, powder charge process are organically combined, make operation from dilution, be dissolved into each step of administration and all separate respectively and carry out.This utility model makes duplex syringe, container and ejecting device organically connect by three-way valve, and the diverse location of regulating spool is realized corresponding step.The lysate owing to when producing or use, in two syringes, packed into, having packed in two containers needs dilution or dissolved drug, according to the diverse location of operation sequence conversion spool, this utility model just can be realized from diluting, be dissolved into the overall process of administration during use.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail: among the described embodiment of Fig. 1, integrated two-chamber administrator is by syringe 1 and fixed support 2 that two syringes are coupled together, one end has the container 4 of removable seal member, support 7 is fixing with container 4 with two syringes 1, and two isolating three-way valve 3 constitute, wherein first port of three-way valve links to each other with a syringe conehead, second port links to each other with a container, and the 3rd port links to each other with ejecting device.

Fig. 2 is three kinds of ejecting devices.

Fig. 4 is another embodiment of three-way valve, is made up of valve housing and a spool of three ports two separate each.

Fig. 5 is made up of a housing and a spool of having six ports for the another embodiment of three-way valve.

During use with the spool of three-way valve from home position Fig. 6, be rotated into dosing state diagram 7 positions, at this moment syringe communicates with container but does not communicate with shower nozzle, lysate in the syringe is pushed in the container, behind the mixed dissolution, solution suction syringe, rotary spool becomes user mode Fig. 8 position in container for medicine, lysate, this position makes syringe communicate with shower nozzle but does not communicate with container, and the medicinal liquid release is got final product.
