Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a vacuum blood collection tube.
Background
The blood drawing is an important link for physical examination, the blood drawing examination generally adopts a vein blood drawing mode, and a nurse in a hospital has a large workload during physical examination, particularly during physical examination of a centralized person, because one end of a blood taking needle which penetrates into a vein needs to be fixed by one hand after one end of the blood taking needle penetrates into the vein during the blood drawing, and then the other end of the blood taking needle penetrates into a vacuum blood taking tube by the other hand; if the blood is collected from multiple tubes, the needle inserted into the vacuum blood collection tube is pulled out, and then inserted into another vacuum blood collection tube, and the steps are repeated until the blood collection is finished.
As a result of the above-mentioned prior art analysis, there are roughly two disadvantages: 1. because the blood taking needle for puncturing the vein needs to be pressed by one hand, when the other end of the blood taking needle punctures the vacuum blood taking tube, only one free hand is left, the operation difficulty is increased by one hand, and the puncture is easy to deviate, the finger is punctured and the cross infection is caused. 2. When multi-tube blood sampling is needed, the blood sampling needle left in the blood sampling tube is pulled out, and the operation is also needed by one hand, so that the operation difficulty is increased, and the possibility of introducing pollutants is increased.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the vacuum blood collection tube capable of being operated by one hand, which can effectively reduce the operation difficulty of medical staff in the blood collection process, increase the safety of the medical staff and reduce the possibility of introducing pollutants.
The technical scheme adopted by the invention has two forms, which are respectively as follows:
the first scheme comprises the following steps: a vacuum blood collection tube capable of being operated by one hand comprises a blood collection needle and a vacuum blood collection bottle; the vacuum blood collection tube capable of being operated by one hand further comprises an outer cover, a propeller, a positioning platform and a guiding platform; positioning platform and enclosing cover inner wall body coupling, positioning platform separate into an inclosed enclosing cover cavity with the enclosing cover, blood taking needle and propeller all set up in the enclosing cover cavity, and the pjncture needle of blood taking needle inserts the positioning platform after passing propeller and guide platform's centre bore in proper order in, enclosing cover inside wall lower extreme is equipped with the internal thread, vacuum test bottle lateral wall upper end is equipped with the external screw thread, vacuum test bottle and enclosing cover threaded connection.
Scheme II: a vacuum blood collection tube capable of being operated by one hand comprises a blood collection needle and two or more vacuum blood collection bottles; the vacuum blood collection tube capable of being operated by one hand further comprises an outer cover, a positioning platform and two or more than two propellers; location platform and enclosing cover inner wall body coupling, location platform separate into an inclosed enclosing cover cavity with the enclosing cover, and the circular slot of two or two above vertical settings is all seted up to the location platform upper surface, blood taking needle and two or two above propulsors all set up in the enclosing cover cavity, the blood taking needle includes vein end needle protective cap, vein end needle, handheld handle, hose and two or more than two pjncture needles, vein end needle protective cap cover is established at the syringe needle end of vein end needle, the needle handle intercommunication of handheld handle one end and vein end needle, the handheld handle other end and hose one end intercommunication, the hose other end is equipped with two or more than two branch hoses, two or more than two branch hose end respectively with the needle handle intercommunication of a pjncture needle, two or more than two pjncture needles of blood taking needle all pass in proper order corresponding propeller and the location platform circular slot insert in the location platform, two or more than two screw holes have been seted up to the location platform bottom surface, two or more than two screw hole centers and corresponding the circular slot center is on same vertical straight line, two or more than two vacuum bottle upper ends all are equipped with the external screw thread connection screw thread on the blood taking bottle and the location platform.
The invention has the beneficial effects that:
1. the blood taking needle is completely sealed in the cavity of the outer cover, and is not required to be packaged separately, so that the operation flow in the use process is reduced, and the risk of pollution to the blood taking needle is reduced.
2. When the puncture needle is used, particularly when the puncture needle is inserted into the rubber plug, the operation can be independently carried out by one hand by using the propeller, so that the working difficulty and the risk of cross infection caused by accidental injury of medical personnel are reduced.
3. In the second scheme of the invention, in the blood sampling process, particularly when multi-tube blood samples need to be collected, because each blood sampling bottle is provided with the puncture needle, after the first tube blood collection is finished, the puncture needle does not need to be pulled out, and only the puncture needle at the upper part of the other tube needs to be inserted.
4. The first scheme of the invention is mainly used for the condition that only one tube of blood needs to be collected, and the second scheme of the invention is used for the condition that multi-tube blood needs to be collected.
