Abstract
The utility model relates to a hemostix and belongs to the technical field of medical instruments. The hemostix with adjustable depth comprises a screw cap, wherein a pressing block is arranged in the screw cap; a spring sleeve is in threaded connection with the lower end of the screw cap; a spring is arranged in the spring sleeve; the lower end of the spring is connected with a push rod; the push rod is connected with a blood taking needle; the push rod is sleeved in a blood taking cover; and a scale mark is arranged on the blood taking cover. According to the hemostix with adjustable depth provided by the utility model, the blood taking needle extends out of the blood taking cover under the action of an elastic force of the spring and the extending length can be directly observed through the scale mark, so that the length of the blood taking needle can be adjusted according to the skin and blood vessel conditions of different people; the operation is simple and convenient; and the hemostix with adjustable depth is easy to use.
Description
Technical field
This utility model relates to hemostix, belongs to technical field of medical instruments.
Background technology
At present, numerous disease all can be judged and formulates therapeutic scheme through detecting blood sample, so medical personnel will take a blood sample usually; But everyone physical ability situation and vascular condition all are different; This just has strict requirement to the degree of depth in when blood sampling, generally all needs empirical medical personnel and takes a blood sample, existing hemostix function singleness; The blood sampling degree of depth is not accurate, usually brings very big worry to medical personnel.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and the hemostix of a kind of reasonable in design, easy and simple to handle, depth-adjustment is provided.
This utility model is realized through following technical scheme:
A kind of hemostix of depth-adjustment, its special character is to comprise screw-cap 1, is provided with briquetting 2 in the screw-cap 1; Screw-cap 1 lower end screw thread is connected with spring housing 3; Be provided with spring 4 in the spring housing 3, spring 4 lower ends are connected with push rod 6, and push rod 6 is connected with blood taking needle 7; Push rod 6 is enclosed within the blood sampling cover 5, and blood sampling cover 5 is provided with graduation mark 8.
The hemostix of this utility model depth-adjustment; The elastic force that produces through spring stretches out blood taking needle outside the blood sampling cover, and the length of stretching out all the scaleover line can observe directly the length that so just can regulate blood taking needle according to the skin and the vascular condition of different people; Easy and simple to handle, be easy to use.
