Abstract
The utility model discloses a negative pressure hemospast, which aims at overcoming the shortage of blood pollution and the manual operation difference of existing hemospast. The utility model comprises blood suction tube, a sealing cover on the blood suction tube and a needle seat with pinhead. The other end of the needle seat with pinhead penetrates the sealing cover; the pinhead is covered by a thin sealing sleeve that is easy to be penetrated to maintain certain vacuum within the blood suction tube. One end of the needle seat with pinhead is sleeved by a rigid protective coat. The utility model has the advantages of unibody structure in a whole, good sealability and can reduce results of hemolysis caused by blood pollution and malfunctions. The utility model is convenient to carry.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of negative pressure hemospast.
Background technology
The present hemospast that uses comprises the lid on bloodletting tube, the bloodletting tube and has the flexible pipe of needle point, will pierce through lid with hose end during use, and blood is stayed in the pipe.But when the blood venous pressure was low, blood was difficult for flowing out, and is prior because bloodletting tube separates with syringe needle, flexible pipe, causes the pollution and the manual operation error of blood easily.
Summary of the invention
In order to overcome the deficiency that existing hemospast causes blood contamination and manual operation error easily, this utility model provides a kind of integrated negative pressure hemospast of safety again simple to operate.
This utility model for the technical scheme that solves its technical problem and adopt is: this negative pressure hemospast comprises the seal cover that has on graduated bloodletting tube, the bloodletting tube, the needle stand that has syringe needle, the described seal cover of other end hermetic penetrant of this needle stand, described syringe needle is with a slim sealing shroud that easily pierces through, and keeps the certain vacuum degree in this bloodletting tube.
Needle stand one end of band syringe needle also is with the protection overcoat of a hard, protects syringe needle with this.
The beneficial effects of the utility model are: because described syringe needle is with a slim sealing shroud that easily pierces through, syringe needle slim sealing shroud when thrusting skin also is pierced when therefore drawing blood, again because existence, the blood of the interior negative pressure of bloodletting tube can enter bloodletting tube; Adding described protection overcoat is convenient to carry before and after the blood drawing.Therefore this utility model is one on overall structure, and good airproof performance has reduced the pollution of blood and the results such as haemolysis that maloperation causes; Simultaneously easy to carry.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: referring to Fig. 1; this utility model comprises the seal cover 2 that has on graduated bloodletting tube 1, this bloodletting tube, the needle stand 3 that has syringe needle 4; the other end hermetic penetrant seal cover 2 of this needle stand 3; needle stand 3 and bloodletting tube 1 are communicated; syringe needle 4 is with a slim sealing shroud 5 that easily pierces through, and needle stand 3 one ends that have syringe needle 4 also are with the protection overcoat 6 of a hard.Extract air in the bloodletting tube 1 out, keep in the bloodletting tube 1 certain vacuum being arranged, according to the negative-pressure vacuum degree in the concrete blood drawing amount decision bloodletting tube 1.Seal cover 2 can adopt gum elastic, and needle stand 3 and protection overcoat 6 can adopt rigid plastics, the slim natural rubber that sealing shroud 5 can adopt elasticity easily to pierce through preferably.When not using,, therefore strengthened sealing (promptly keeping the vacuum in the bloodletting tube 1) and be easy to carry again because sealing shroud 5 sealing syringe needles 4 add protection overcoat 6; During use; extract protection overcoat 6 from needle stand 3; the syringe needle 4 that has slim sealing shroud 5 thrust skin, simultaneously slim sealing shroud 5 also is pierced; blood is under the effect of negative pressure; be easy to just flow in the bloodletting tube 1; after using end, extract syringe needle 4, protect overcoat 6 to be sheathed on needle stand 3 again, safety again easy to carry like this.
Claims (2)
1, a kind of negative pressure hemospast, comprise the seal cover (2) that has on graduated bloodletting tube (1), the bloodletting tube (1), the needle stand (3) that has syringe needle (4), it is characterized in that: needle stand (3) other end hermetic penetrant seal cover (2) that has syringe needle (4), syringe needle (4) is with a slim sealing shroud (5) that easily pierces through, and keeps the certain vacuum degree in the bloodletting tube (1).
