Abstract
The utility model discloses a needle-free dosing device of infusion apparatus. The needle-free dosing device of the infusion apparatus comprises a screw cap, a rubber plug and a Y-shaped pipe, wherein the Y-shaped pipe is provided with a dosing port, the rubber plug is cylindrical, an opening of the rubber plug is communicated with the dosing port, and a through hole is formed in the bottom of the rubber plug. When no external force acts, the through hole is in a closed state. When external force is applied to the position of the through hole, the through hole is opened. The screw cap is arranged at the outer side of the rubber plug, one end of the screw cap is fixedly connected with the Y-shaped pipe, and a thread is arranged at the outer side of the screw cap. The needle-free dosing device of the infusion apparatus adopts the dosing method that an injector with a screw port is tightly screwed with the screw cap of the dosing device, the force generated when the screw port is screwed with the screw cap pushes the through hole in the bottom of the rubber plug open, and accordingly liquid medicine needing to be dosed is added to the dosing device through an infusion hole. Through the adoption of the dosing method, not only can the pollution to the dosing device by the external environment be effectively avoided, but also repeated operation can be carried out at the same time, and therefore resources are effectively saved.
Description
Technical field
This utility model relates to the chemicals dosing plant in the transfusion device, belongs to medical instruments field.
Background technology
The kind of transfusion device is a lot of in the market, yet the Needleless dosing device of most of transfusion devices all is to adopt traditional dosing pattern, namely utilizing draw point to puncture the plug top joins the medicinal liquid of required adding in the chemicals dosing plant, such operation not only causes the pollution to chemicals dosing plant easily, and each used needle tubing of dosing all must discard after dosing is finished, and has so also caused the waste of resource.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can not be subjected to outside contamination and can save the chemicals dosing plant of resource in the dosing process.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is as follows:
A kind of Needleless dosing device of transfusion device comprises screw lid, plug and Y-pipe, and described Y-pipe has dosing mouth, described plug is drum shape, the described dosing mouth of the open communication of described plug, and the bottom of described plug is provided with through hole, when no external force is done the time spent, described through hole is closed state; When applying external force in described through hole, described through hole is opened, and the arranged outside of described plug has described screw lid, the fixedly connected described Y-pipe of an end of described screw lid, and the arranged outside of described screw lid has screw thread.
Further, described through hole is round taper hole.
Further, the arranged outside of described plug has first step trough, and the inboard of described screw lid is provided with second step trough corresponding with described first step trough.
Further, described first step trough comprises two grooves.
Further, the thickness bottom the described plug is 4-5mm.
Beneficial effect: this utility model compared with prior art, have the following advantages: and the dosing method that this utility model chemicals dosing plant adopts is that the syringe of band screw socket and the screw lid in this chemicals dosing plant are screwed tight, the power that they produce in screwing tight process is squeezed the through hole of plug bottom and is opened, thereby the medicinal liquid of required adding just joins in the chemicals dosing plant by infusion hole, adopt such dosing method not only can effectively avoid external environment to the pollution of chemicals dosing plant, can also operate repeatedly simultaneously, therefore effectively save resource.
Description of drawings
The structural representation of chemicals dosing plant in the transfusion device that Fig. 1 provides for this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further explanation.
As shown in Figure 1, transfusion device chemicals dosing plant of the present utility model comprises screw lid 1, plug 2 and Y-pipe 3, and Y-pipe 3 has dosing mouth 31, and plug 2 is drum shape, the open communication dosing mouth 31 of plug 2, and the bottom of plug 2 is provided with through hole 4.The thickness of plug 2 bottoms is 4-5mm.When no external force is done the time spent, through hole 4 is closed state, not with external environment connect, thereby plays the effect of protection chemicals dosing plant internal medium; When applying external force at through hole 4 places, through hole 4 is opened.Wherein, through hole is round taper hole.The arranged outside of plug 2 has screw lid 1, the fixedly connected Y-pipe 3 of an end of screw lid 1, and the arranged outside of screw lid 1 has screw thread.Wherein, the arranged outside of plug 2 has first step trough, and the inboard of screw lid is provided with second step trough corresponding with first step trough.Preferably, first step trough comprises two grooves.
When in infusion process, needing in transfusion device, to add medicinal liquid, to have the screw socket syringe of required medicinal liquid or screw socket and screw lid 1 rotation of other infusion products screws tight, screw socket and screw lid 1 can apply an active force to through hole 4 in screwing tight process, through hole 4 is squeezed under the effect of this power and is opened, required medicinal liquid just joins in the transfusion device by through hole 4, after dosing is finished, screw socket syringe or other infusion products are taken off from screw lid 1, through hole 4 just returns to closure state again, plug 2 is made by the silicone rubber material, has good contractility and elasticity.
This utility model compared with prior art, have the following advantages: and the dosing method that this utility model chemicals dosing plant adopts is that the syringe of band screw socket and the screw lid in this chemicals dosing plant are screwed tight, the power that they produce in screwing tight process is squeezed the infusion hole at plug top and is opened, thereby the medicinal liquid of required adding just joins in the chemicals dosing plant by infusion hole, adopt such dosing method not only can effectively avoid external environment to the pollution of chemicals dosing plant, can also operate repeatedly simultaneously, therefore effectively save resource.
