Abstract
The utility model relates to a microscale blood sampling pen with a conveniently-dismountable needle and a conveniently-dismountable cap, which comprises a penholder (1), a pen cap (2), a spring (3), an elastic rod (4), a control key (5), an elastic lock catch (6), a lock hole (7), a needle stand sleeve (8), a needle stand (9), a needle rod (10), a needle head (11) and a needle hole (12), wherein the needle stand (9), the needle rod (10) and the needle head (11) are connected into a whole to form a blood sampling needle. The blood sampling pen is characterized in that the pen cap (2) is buckled on the penholder (1); the diameter of the needle hole (12) on the pen cap (2) is smaller than that of the needle rod (10) of the blood sampling needle; the needle head (11) extends out of the needle hole (12) to a length of 2 to 3 mm; a sliding chute (13) is formed at the bottom part of the needle stand sleeve (8); the end part of the elastic rod (4) is arranged in the sliding chute (13); and a push rod (14) is connected to the tail part of the elastic rod (4). By adopting the utility model, after one-time blood sampling, the pen cap and the blood sampling needle can be pushed out and discarded; and a new blood sampling needle and a new pen cap are replaced, thereby preventing cross infection and pollution to medical staff and being safe and reliable.
Description
Technical field
This utility model belongs to the medical apparatus technical field, relates in particular to the trace blood pen of a kind of pin for convenience detach and medicated cap.
Background technology
Traditional blood taking needle generally fixedly is made of syringe needle and needle handle, and often sterilization is reused, otherwise cost is increased; The present disposable blood taking needle that occurs, whenever adopted one after, back out the blood sampling cap for brush, change new blood taking needle, continue to use the former blood sampling cap for brush, speckle with patient's bloodstain on the cap for brush of taking a blood sample, easily cause cross infection, often bring bigger misery to the patient.In addition, when changing blood taking needle, medical personnel will screw on and back out with the hands cap for brush of will taking a blood sample, and also easily pollute at every turn.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of trace blood pen that does not have cross infection and pin for convenience detach and medicated cap is provided.The realization the technical solution of the utility model is: this utility model includes penholder, the cap for brush, spring, elastic rod, control key, elastic lock, keyhole, needle stand cover, needle stand, shank, syringe needle and pin hole, wherein needle stand, shank and syringe needle disjunctor constitute blood taking needle in one, it is characterized in that the cap for brush is not with a chain for binding criminals stricture of vagina, be buckled on the penholder.The diameter of pin hole is less than the diameter of blood taking needle shank on the cap for brush, and syringe needle ejects the outer length of pin hole between 2～3mm.The bottom of needle stand cover is provided with chute, and the end of elastic rod is located in the chute.The afterbody of elastic rod connects a push rod, and the tail end of push rod is provided with and pushes away handle.Said elastic rod and push rod constitute one, and spring housing is contained on the push rod.
After this utility model was once taken a blood sample, medical personnel needn't back out the cap for brush with hands, and the cap for brush and blood taking needle can be released discarded with push rod simultaneously, use the new blood taking needle and the cap for brush again instead, had prevented cross infection and to medical personnel's pollution, and are safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, penholder, 2, the cap for brush, 3, spring, 4, elastic rod, 5, control key, 6, elastic lock, 7, keyhole, 8, the needle stand cover, 9, needle stand, 10, shank, 11, syringe needle, 12, pin hole, 13, chute, 14, push rod, 15, push away handle.
The specific embodiment
With reference to accompanying drawing, this utility model includes penholder 1, the cap for brush 2, spring 3, elastic rod 4, control key 5, elastic lock 6, keyhole 7, needle stand cover 8, needle stand 9, shank 10, syringe needle 11 and pin hole 12, wherein needle stand 9, shank 10 and syringe needle 11 disjunctors constitute blood taking needle in one, it is characterized in that the cap for brush 2 is not with a chain for binding criminals stricture of vagina, be buckled on the penholder 1.The diameter of pin hole 12 is less than the diameter of blood taking needle shank 10 on the cap for brush 2, and syringe needle (11) ejects the outer length of pin hole (12) between 2～3mm.The bottom of needle stand cover 8 is provided with chute 13, and the end of elastic rod 4 is located in the chute 13.The afterbody of elastic rod 4 connects a push rod 14, and the tail end of push rod 14 is provided with and pushes away handle 15.Said elastic rod 4 and push rod 14 constitute one, and spring 3 is sleeved on the push rod 14.
Use of the present utility model is: blood sampling medicated cap 2 and blood taking needle are aseptic, and blood taking needle is placed in the needle stand cover 8, buckle blood sampling medicated cap 2, then push rod 14 is pulled back, drive elastic rod 4 and move backward, elastic rod 4 was lockable when elastic lock 6 fell into keyhole 7, spring 3 energy storage.When pressing control key 5, elastic rod 4 loses snap close power, and under the effect of spring 3, elastic rod 4 promotes blood taking needle forward and launches, and takes a blood sample.After the blood sampling, pin and push away handle 15 and push away forward, because the cap for brush 2 is buckled on the penholder 1, because the diameter of pin hole 12 is less than the diameter of blood taking needle shank 10 on the cap for brush 2, the cap for brush 2 and blood taking needle are pushed out discarded under the effect of push rod 14 simultaneously again.
