When hospital carried out blood collection to the patient, the medical worker directly entered pipe close puncture needle (containing haemostatic sheath) puncture with hands in the plug (containing safety helmet in case of necessity) of blood taking tube and takes a blood sample; After finishing, blood sampling directly body is extracted from the pipe close puncture needle with hands again.The potential safety hazard that this operation exists is: blood sampling finishes, and the frictional force when pulling out pin between needle body and plug causes pipe close to separate greater than the frictional force between plug and the test tube easily, and consequence is: 1, cause the blood collection failure; 2, make the interior blood of blood taking tube trickle out and pollute medical worker, patient and operating environment.
The utility model content
At above-mentioned defective; the technical problem that this utility model solves is to provide a kind of safe blood sampling tube needle sleeve of taking off; be intended to solve the pipe close that blood collection finishes to exist when directly extract in the pipe close puncture needle with body the back and separate collection of specimens failure and the pollution problem that causes, protection medical worker, patient's safety and blood preparation safely, prevent from polluting, sampling quantity is accurate.
In order to solve above technical problem, the safety that this utility model provides take off the blood sampling tube needle sleeve, comprise sleeve body, one end of described sleeve body is opening, and the other end is the seat board end, and the seat board end of described sleeve body is provided with seat board, the inside of described seat board end is connected with push pedal by the push pedal spring, described push pedal is provided with buckle, and described seat board is provided with first through hole and block button hole, and described buckle and described block button hole cooperate; Described seat board end be externally connected to support cap, the middle part of described support cap is provided with second through hole, described first through hole and described second through hole communicate, be provided with button in the described support cap, described button promotes described buckle and breaks away from the conveying block button hole when described buckle is fastened on the described block button hole, described button extends to the outside of described support cap.
Preferably, described push pedal is provided with plural pillar, described seat board is provided with pillar hole, and the head that described pillar passes described pillar hole and described pillar is provided with back-off, and described push pedal spring housing is connected on the described pillar and is positioned at the inside of described seat board end.
Preferably, described push pedal is provided with three pillars, and described pillar is triangle arrangement in described push pedal.
Preferably, described button comprises by portion and push rod, describedly is connected with described push rod one by portion, and described push rod is arc and promotes described buckle under by the promotion of portion and break away from the conveying block button hole described.
Preferably, described button also comprises the button secondary spring, and described button secondary spring one end is connected the middle part of described support cap, and the other end is connected described by portion or described push rod.
Preferably, the internal diameter of described sleeve body is greater than the external diameter of blood taking tube.
Compared with prior art; the safety that this utility model provides take off the blood sampling tube needle sleeve; push pedal promotes blood taking tube and separates with blood taking needle; in blood taking tube and blood taking needle separation process; push pedal is because next directes reach and stays in blood taking tube cock cap surface in the effect of push pedal spring; so pipe close can not occur separates; more can not occur separating the collection of specimens failure cause and to the pollution of medical worker, patient and operating environment because of pipe close, thus protection medical worker, patient's safety and blood preparation safely, prevent from polluting, sampling quantity is accurate.

The specific embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.
See also Fig. 1-Fig. 4, Fig. 1 is the use structure chart that takes off the blood sampling tube needle sleeve of safety among this utility model embodiment; Fig. 2 is the use decomposition chart that takes off the blood sampling tube needle sleeve of safety among this utility model embodiment; Fig. 3 is the structure chart that takes off the blood sampling tube needle sleeve of safety among this utility model embodiment; Fig. 4 is the decomposition chart that takes off the blood sampling tube needle sleeve of safety among this utility model embodiment.
The safety that this utility model embodiment provides take off the blood sampling tube needle sleeve, comprise sleeve body 6, one end of sleeve body 6 is opening, the other end is the seat board end, and the internal diameter of sleeve body 6 is greater than the external diameter of blood taking tube 8, and the seat board end of sleeve body 6 is provided with seat board, the inside of seat board end is connected with push pedal 5 by push pedal spring 2, push pedal 5 is provided with buckle, and seat board is provided with first through hole and block button hole, and buckle and block button hole cooperate; The seat board end be externally connected to support cap 1, the middle part of support cap 1 is provided with second through hole, and first through hole and second through hole communicate, and are provided with button 3 in the support cap 1, button 3 promotes buckle and breaks away from the conveying block button hole when buckle is fastened on the block button hole, button 3 extends to the outside of support cap 1.
