Abstract
The invention relates to a blood collector, belongs to the technical field of medical equipment and relates to a length-adjustable medical blood collection device convenient to mount and demount. The medical blood collection device comprises a screw cap. A pressure block is disposed in the screw cap. A spring sleeve is connected to the lower end of the screw cap in a threaded manner. A spring is disposed in the spring sleeve. The lower end of the spring is connected with a push rod which is connected with a collection needle. The push rod is nested in a collection sleeve which is provided with graduation marks. The collection needle of the medical blood collection device is extended out of the collection sleeve through elasticity of the spring, each extension length exceeding the graduation marks is directly observable, and accordingly, the length of the collection needle can be adjusted according to skin and vessel conditions of different people. The length-adjustable medical blood collection device is simple to operate and easy to use.
Description
Technical field
The present invention relates to blood-taking device, belong to technical field of medical instruments.
Background technology
At present, numerous disease all can be judged and be formulated therapeutic scheme by detecting blood sample, so medical personnel will be taken a blood sample usually, but everyone physical ability situation and vascular condition are different, this just has strict requirement to the degree of depth in when blood sampling, generally all needs experienced medical personnel to be taken a blood sample, existing hemostix function singleness, the blood sampling degree of depth is not accurate, usually to medical personnel, brings very large worry.
Summary of the invention
The object of the invention is to solve the weak point that above-mentioned prior art exists, provide a kind of reasonable in design, easy and simple to handle, be convenient to remove and install, length-adjustable Medical blood sampling equipment.
The present invention is achieved by the following technical solutions:
A kind ofly be convenient to remove and install, length-adjustable Medical blood sampling equipment, its special character is to comprise screw-cap 1, be provided with briquetting 2 in screw-cap 1, the screw-cap 1 lower end spring housing 3 that has been threaded, be provided with spring 4 in 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 blood sampling cover 5, and blood sampling cover 5 is provided with graduation mark 8.
The present invention is convenient to remove and install, length-adjustable Medical blood sampling equipment, the elastic force produced by 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 skin and the vascular condition of different people, easy and simple to handle, be easy to use.
The accompanying drawing explanation
Fig. 1: the present invention is convenient to remove and install, length-adjustable Medical blood sampling equipment structural representation;
In figure: 1: screw-cap; 2: briquetting; 3: spring; 4: spring housing; 5: the blood sampling cover; 6: push rod; 7: blood taking needle; 8, graduation mark.
The specific embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for formation of the present invention is described in further detail.
Being convenient to of the present embodiment removes and installs, length-adjustable Medical blood sampling equipment, comprise screw-cap 1, be provided with briquetting 2 in screw-cap 1, the screw-cap 1 lower end spring housing 3 that has been threaded, be provided with spring 4 in 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 blood sampling cover 5, and blood sampling cover 5 is provided with graduation mark 8.
The present embodiment is convenient to remove and install, length-adjustable Medical blood sampling equipment, the elastic force produced by 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 skin and the vascular condition of different people, easy and simple to handle, be easy to use.
