Abstract
The utility model discloses a checking blood taking needle, which belongs to the medical treatment checking technology field. The technical proposal of the utility model is that a general injection needle head is included, the lower half of the general injection needle bevel is closed, the upper half is closely linked. The utility model has the advantages of that the structure is simple and the process is easy. Since the lower half of the bevel is closed, the taken blood is the middle blood of the blood flow, thereby the suction force produced during phlebotomizing does not cause damage to the blood vessel wall or to the blood vessel wall hollow in the needle head bevel. The utility model relieves the pain and damage of the patient.
Description
Technical field: this utility model belongs to medical detection technology, is a kind of check blood collection needles specifically.
Background technology: the present blood taking needle that uses of clinical laboratory, be common pumping needle, its needle slope is whole hollow.When this blood collection needles is taken a blood sample in blood vessel,, make patient feel pain, even can cause the damage of blood vessel wall because the effect of suction often causes the depression of needle slope place blood vessel wall.
Summary of the invention: for overcoming above-mentioned shortcoming, when the purpose of this utility model is a kind of blood sampling of design, can not cause that blood vessel wall caves in and the check blood collection needles of vascular damaged.
The technical solution of the utility model is: comprise common injection needle, with 1/2nd sealings under the common injection needle inclined-plane, last 1/2nd communicate.
The beneficial effects of the utility model are: this utility model is simple in structure, and is easy to manufacture.Owing to following 1/2nd sealings on inclined-plane, so the blood of taking out is the blood at blood flow middle part, the suction that is produced during blood drawing can not cause the depression of needle slope place blood vessel wall and the damage of blood vessel wall when drawing blood to patient.Patient's pain and damage have been alleviated.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1, the syringe needle enclosure portion, 2, the syringe needle part that communicates.
The specific embodiment: comprise common injection needle, will 1/2nd be designed to enclosure portion 1 under the common injection needle inclined-plane, last 1/2nd parts 2 that are designed to communicate.During use, using method is with common injection needle, and the blood of being taken out is the blood at blood flow middle part, can not cause the depression and the damage of blood vessel wall.
Claims (1)
1, the check blood collection needles comprises common injection needle, it is characterized in that: will be under the common injection needle inclined-plane 1/2nd be designed to enclosure portion (1), last 1/2nd be designed to communicate partly (2).
