Abstract
The utility model discloses a disposable fully-sealed blood collector which comprises a needle head 1, a nipple 2, a piston cylinder 3, a piston 4, a piston shaft 5, a piston shaft handle 6, an inflatable tube 7and an inflatable ball 8; the utility model is characterized in that the cylinder wall between the nipple 2 and the piston cylinder 3 is provided with a blood drawing one-way valve 9, the piston 4 is provided with a blood inlet one-way valve 10 and a blood outlet one-way valve 11, the piston shaft 5 is a column and provided with a hollow chamber 12, the center of the pistons shaft handle 6 is provided with a through hole 13, one end of the inflatable tube 7 is connected with the through hole 13 and its other end is connected with the inflatable ball 8. The disposable fully-sealed blood collector has the simple structure and convenient operation, and can avoid the pollution of blood sample and the cross infection.
Description
Technical field
This utility model relates to a kind of medical appliance, specifically a kind of disposable fully-sealed hemostix.
Background technology
Blood donor no matter at present, still healthy people haves a medical check-up, and hospitalize is cured the disease, and the chemical examination of generally all will taking a blood sample by blood test, is made a definite diagnosis blood donor's blood group and the compound condition of donating blood whether, and the people that other are taken a blood sample and chemically examine also is to make a definite diagnosis the cause of disease by blood test.Blood sampling is now mainly taken a blood sample with syringe, and then according to lab work, is divided in vitro, and the weak point of this blood-sampling method is after blood sampling, pollutes easily and cross infection in the blood sample transfer process; Secondly blood-sampling method is to take a blood sample with the disposal vacuum volumetric hemostix, this blood-sampling method, and also cumbersome because of operating, needle tubing is thick, and venipuncture is difficult to once success, is difficult to apply.
Summary of the invention
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and blood sampling is integrated with test tube, and blood sampling and shifting under the condition of sealing fully can avoid polluting the disposable fully-sealed hemostix with cross infection.
For reaching above purpose, technical solution adopted in the utility model is: this disposable fully-sealed hemostix, by syringe needle, nipple, piston cylinder, piston, the axis of the piston, the piston footstalk, gas tube, inflatable ball constitutes, it is characterized in that on the barrel between nipple and the piston cylinder, establishing the blood drawing check valve, on piston, establish into blood check valve and hemorrhage check valve, advance the spring strength of blood check valve, should be when the blood drawing check valve be opened, still keep closed state, the axis of the piston is cylinder and establishes cavity, through hole is established at piston footstalk center, and gas tube one end is connected with through hole, and the other end and inflatable ball are joined.This utility model is also implemented by following measure: described the axis of the piston is that transparent plastic is made, and establishes scale on outer wall, so that observe blood volume.When using this utility model, after medical personnel are thrust the human vein blood vessel with syringe needle, begin blood sampling, when the pulling the axis of the piston, the blood drawing one-way valve opens, blood enters in the piston cylinder, when reaching requirement, syringe needle is extracted out from the human vein blood vessel, promoted the axis of the piston, piston compression blood is opened into blood check valve, enter in the cavity of the axis of the piston, after blood sampling is finished, whole hemostix is transferred to the laboratory, when chemically examining, piston is extracted out, as long as inflate in the axis of the piston cavity, blood is opened hemorrhage check valve blood sample and is flowed out under the effect of air pressure.
The beneficial effects of the utility model are: compare with present blood-sampling method, have simple in structurely, easy to operate, can avoid blood sample to pollute and the advantage of cross infection.
Description of drawings
Fig. 1 looks sketch map for this utility model structure master.
Fig. 2 be this utility model along A-A to cross-sectional schematic.
The specific embodiment
Make this utility model with reference to accompanying drawing 1,2.This disposable fully-sealed hemostix, constitute by syringe needle 1, nipple 2, piston cylinder 3, piston 4, the axis of the piston 5, piston footstalk 6, gas tube 7, inflatable ball 8, it is characterized in that on the barrel between nipple 2 and the piston cylinder 3, establishing blood drawing check valve 9, on piston 4, establish into blood check valve 10 and hemorrhage check valve 11, the axis of the piston 5 is for cylinder and establish cavity 12, through hole 13 is established at piston footstalk 6 centers, and gas tube 7 one ends are connected with through hole 13, and the other end and inflatable ball 8 are joined.Described the axis of the piston 5 is made for transparent plastic, and establishes scale 14 on outer wall.
