Abstract
The utility model discloses a negative pressure hemospast, which comprises a hemospasia induced tube, a cover on the hemospasia induced tube, a hose with a pinhead, and a puncture head at the terminal of the hose, and is characterized in that: the hemospasia induced tube internally has a sealing structure so as to retain a certain vacuum degree, the sealing structure has a relative thinner round part at the center; an elastic supporting rack is also arranged on the sealing structure and is slightly higher than the tube mouth of the mouth of the hemospasia induced tube; the hose and the cover of the hemospasia induced tube are integrated, the length of the puncture head at the terminal of the hose is slightly less than the height of the supporting rack, but slightly more than the distance between the sealing structure and the tube mouth. The utility model has the advantages of integral structure on the whole, good sealing performance, reduces the results of hemolysis, etc. caused by blood pollution and error operation; under negative pressure condition, the hemospast is propitious to blood flowing and is convenient to be taken along with.
Description
This utility model relates to a kind of medical apparatus and instruments, specifically relates to a kind of negative pressure hemospast.
The present hemospast that uses comprises the lid on bloodletting tube, the bloodletting tube and has the flexible pipe of syringe needle, will pierce through lid with hose end during use, makes in the blood inflow pipe.But when the blood venous pressure was low, blood was difficult for flowing out, because bloodletting tube separates with syringe needle, flexible pipe, causes the pollution of blood easily in addition.
At the problems referred to above, the purpose of this utility model provides a kind of negative pressure hemospast easy and simple to handle, incorporate.
In order to achieve the above object, the technical solution of the utility model is such: it comprises lid on bloodletting tube, the bloodletting tube, has the flexible pipe of syringe needle, the puncturing head of hose end, it is characterized in that a hermetically-sealed construction is arranged in the described bloodletting tube, certain vacuum is arranged in the holding tube, and the center of sealing structure has a circular portion thinner; On hermetically-sealed construction, also has a flexible supporting frames, a little more than the mouth of pipe of bloodletting tube; The lid of described flexible pipe and bloodletting tube is connected as a single entity, and the length of the puncturing head of hose end is slightly less than the height of bracing frame but is slightly larger than hermetically-sealed construction and the distance of the mouth of pipe.
The utility model has the advantages that on the whole to be structure as a whole that good airproof performance has reduced the pollution of blood and the results such as haemolysis that maloperation causes; Under the negative pressure state, help blood and flow out, be more convenient for carrying.
Further specify this utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, this utility model comprises lid 2 on bloodletting tube 1, the bloodletting tube, has the flexible pipe 3 of syringe needle, the puncturing head 4 of hose end, it is characterized in that a hermetically-sealed construction 5 is arranged in the described bloodletting tube 1, extract inner air tube out, certain vacuum is arranged in the holding tube, require the pipe internal pressure usually less than 0.588KPa.The center of sealing structure 5 has a circular portion thinner; On hermetically-sealed construction 5, also has a flexible supporting frames 6, a little more than the mouth of pipe of bloodletting tube 1; Described flexible pipe 3 is connected as a single entity with the lid 2 of bloodletting tube, and the length of the puncturing head 4 of hose end is slightly less than the height of bracing frame 6 but is slightly larger than the distance of hermetically-sealed construction 5 and the mouth of pipe.When not using, because the supporting role of bracing frame 6, puncturing head 4 can not sting hermetically-sealed construction 5; During use, firmly press down the lid 2, puncturing head 4 will puncture the thin part of hermetically-sealed construction 5, and blood is easy to just flow in the bloodletting tube 1 under negative pressure.
