Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to blood taking needle for medical science inspection.
Background
The collection of the venous blood specimen is one of clinical commonly used diagnosis and treatment methods, a commonly used venous blood taking needle and a negative pressure collection container are matched with each other to complete the establishment of a venous channel, and the negative pressure collection container provides preset collection capacity (negative pressure) and pretreatment (different additives) for the specimen so as to meet and ensure the safety, effectiveness, reliability and accuracy of the collection of the venous blood specimen. At present, the split (flexible tube) venous blood taking needle which is used in China mostly consists of a protective cap, a puncture needle, a needle seat (also used as a single-wing piece handle), a flexible tube, a connecting seat, a blood collecting needle and a blood blocking sleeve. Because it does not contain a needle holder, the following risks exist in the operation: the blood collection needle and the negative pressure collection container are inserted by two hands to realize collection without or without installing a needle holder, so that the fingers are polluted by bloodstain; after the venipuncture is successful, a fixed handle is not required to be applied, and the fixed handle is shaken freely, so that the acquisition speed is influenced, the hemolysis and the blood coagulation of a sample are caused, and even the adverse event that the puncture needle is pulled out occurs; when the needle is pulled out, the hose is pulled and dragged by one hand, the pain of the patient is increased, and the risk of injury caused by the needle is increased by throwing the puncture needle and the catheter; the naked needle tip increases the chance that others are stabbed in the waste disposal process, also increases the risk of infection and transmission of blood-borne diseases.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects and providing a blood taking needle for medical examination.
The utility model aims at realizing through the following technical scheme:
a blood taking needle for medical examination comprises a puncture needle, a needle seat, a compression spring, a handle, a protective device, a catheter, a connecting seat, a luer, a blood collecting needle seat and a blood collecting needle.
A protective cap is arranged outside the needle base.
The left end of the blood collection needle is provided with a blood blocking sleeve.
A needle holder is arranged outside the blood collection needle base.
The utility model discloses following profitable effect has:
the utility model has reasonable design and convenient use, realizes the one-hand collection operation, avoids the needle point deviation in the process of inserting the two hands, lightens the resistance of inserting the two hands, and avoids the blood stain leakage and pollution caused by the rupture of the blood blocking sleeve due to the deviation; compared with the common blood taking needle, the safety protection device is added, the spring is released to drive the puncture needle to retract, shield and limit when the collection is finished, the needle tip exposure phenomenon is eliminated, medical personnel are protected from being injured by the needle, and the device needle is damaged to avoid repeated use.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1, a blood collection needle for medical examination comprises a puncture needle 2, a needle seat 3, a compression spring 4, a handle and protection device 5, a catheter 6, a connecting seat 7, a luer 8, a blood collection needle seat 9 and a blood collection needle 10, wherein the puncture needle 2 is installed on the needle seat 3, the compression spring 4 is further installed on the needle seat 3, the handle and protection device 5 is installed behind the needle seat 3, one end of the catheter 6 is connected with the puncture needle 2, the other end of the catheter is connected with the luer 8, the connecting seat 7 is installed on the right side of the luer 8, the blood collection needle seat 9 is installed on the left side of the luer 8, and the blood collection needle.
The outside of the needle stand 3 is provided with a protective cap 1.
The left end of the blood collection needle is provided with a blood blocking sleeve 11.
A needle holder 12 is arranged outside the blood collection needle seat.
The exact requirement of the lancet structure for triggering the safety protection device is that the lancet structure can be triggered by a pressure greater than 20N, so as to prevent false triggering caused by common touch. After the puncture is successful (blood returns), the puncture handle is fixed with the limb skin by using the adhesive plaster to prevent the puncture needle from swinging; the in-vivo triggering is emphasized when the collection is finished, so that the puncture needle is prevented from being exposed outside the body, and the risk of puncture injury is eliminated; the collection action is completed by a single hand in a mode that the curled edge of the needle holder and the bottom of the negative pressure blood collection tube are pressed mutually (the action is carried out with an injector), the blood collection tube is inserted and the rubber plug is punctured (single-hand operation), and the possibility that fingers are polluted by bloodstain is avoided in the closed environment of the needle holder.
