Abstract
The utility model relates to a medical device and particularly relates to a disposable blood collection device. The disposable blood collection device comprises a syringe needle, a syringe cylinder, a piston, a push rod, a push handle and a syringe-needle protection cap; the syringe needle is arranged on a syringe needle holder through a syringe pin, wherein the syringe needle holder is arranged on the front end of the syringe cylinder; the piston is arranged in the syringe cylinder; and one end of the push rod is connected with the piston, and the other end is provided with the push handle. The disposable blood collection device is characterized by being at least provided with two check spring sheets, wherein the check spring sheets are uniformly distributed on the push rod, one ends of the check spring sheets are vertically connected with the push rod, and the other ends face to the syringe needle. When the disposable blood collection device is in use, the syringe needle pierces into the blood vessel of a patient, the push handle is pulled, the piston is pulled through the push rod to move towards the rear part of the syringe cylinder, the syringe cylinder in front of the piston is vacuumized internally, and the blood in the body of the patient is drawn into the syringe cylinder. In the operation process, along with the backward movement of the push rod, the check spring sheets are pulled out of the syringe cylinder continuously, and the piston can only move backwards. The disposable blood collection device is novel in structure, is easy to operate and is safe to use, and due to the adoption of the disposable blood collection device, the cross infection in the hospital is avoided effectively.
Description
Technical field
This utility model relates to a kind of medical appliance, particularly a kind of disposable blood taking device that can effectively avoid cross infection in hospital.
Background technology
As everyone knows, blood testing is the important means that diagnoses the illness, employed hemostix was traditional syringe when blood sampling was chemically examined for the patient by hospital now, syringe is by syringe needle, syringe, piston, push rod, pushing away handle and syringe needle helmet forms, the syringe needle rear end is provided with pintle, the syringe front end is provided with needle stand, syringe needle is installed on the needle stand of syringe front end through pintle, piston is located in the syringe, push rod one end is connected with piston, the push rod other end is provided with and pushes away handle, during use, syringe needle is thrust in patient's the blood vessel, pulling pushes away handle, haul piston to the syringe rear to movement through push rod, be formed into vacuum in the syringe before the piston and with in the blood suction syringe in the patient body, in the aforesaid operations process, not the blood extracted out of brigadier or air push away with patient body in, namely require piston to move backward, must not move forward, this has the maximum deficiency of syringe-type hemostix can not realize self-destruction, this provides opportunity for indivedual poor doctors of moral qualities, reuse, frequent pin Reusability repeatedly, in addition, some illegal retailers can banish market again with used syringe, do not guarantee the harm that the patient is not infected by antibacterial, more easily cause cross infection in hospital, cause the malpractice that should not occur to occur.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of easy to operate, use safety, can effectively avoid the disposable blood taking device of cross infection in hospital.
This utility model can reach by following measure:
A kind of disposable blood taking device, by syringe needle, syringe, piston, push rod, push away handle and the syringe needle helmet forms, the syringe needle rear end is provided with pintle, the syringe front end is provided with needle stand, syringe needle is installed on the needle stand of syringe front end through pintle, piston is located in the syringe, push rod one end is connected with piston, the other end of push rod is provided with and pushes away handle, it is characterized in that being provided with at least two check spring sheets, the check spring sheet is distributed on the push rod, and check spring sheet one end is connected with push rod is vertical, and the check spring sheet other end is towards the syringe needle direction.
When this utility model uses, syringe needle is thrust in patient's the blood vessel, pulling pushes away handle, haul piston to the syringe rear to movement through push rod, be formed into vacuum in the syringe before the piston and with in the blood suction syringe in the patient body, in the aforesaid operations process, along with moving backward of push rod, the check spring sheet constantly is drawn out syringe so that piston can only move backward, have novel structure, simple to operate, use safety, can effectively prevent the advantage such as cross infection in hospital.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of disposable blood taking device, by syringe needle, syringe 2, piston 3, push rod 4, push away handle 5 and syringe needle helmet 1 composition, the syringe needle rear end is provided with pintle, the syringe front end is provided with needle stand, syringe needle is installed on the needle stand of syringe 2 front ends through pintle, piston 3 is located in the syringe 1, push rod 4 one ends are connected with piston 3, push rod 4 other ends are provided with and push away handle 5, the structure of above-mentioned each ingredient and the interconnected relationship between them are same as the prior art, this does not give unnecessary details, of the present utility model being characterised in that is provided with two check spring sheets 6 at least, check spring sheet 6 is distributed on the push rod 4, check spring sheet 6 one ends and 4 vertical being connected of push rod, check spring sheet 6 other ends are towards the syringe needle direction, when this utility model uses, syringe needle is thrust in patient's the blood vessel, pulling pushes away handle, haul piston to the syringe rear to movement through push rod, be formed into vacuum in the syringe before the piston and with in the blood suction syringe in the patient body, in the aforesaid operations process, along with moving backward of push rod, the check spring sheet constantly is drawn out syringe, so that piston can only move backward, if there is the lawless person that hemostix is reused, then the check spring sheet towards then being to push away the handle direction, be easy to be it is found that, the lawless person can not be, have novel structure, simple to operate, use safety, can effectively prevent the advantages such as cross infection in hospital.
