Description
Technical field
The present invention relates to a kind of dosing needle set, specifically, relate to that a kind of structure is simple, easy to operate, pharmaceutical quantities control accuracy is higher, avoid the intravenous administration dosing needle set of dropping liquid phenomenon completely.
Background technology
When intravenous administration dosing, medical personnel often need the operation carried out carrying out injecting medical liquid in sealed container (cillin bottle or mother liquor vessel) He take out medicinal liquid, when injecting medical liquid operation, because the space inside sealed container has been hermetic, malleation can be formed in sealed container, and along with inject medicinal liquid more, its pressure is larger, medical personnel are needed to use more strength just can complete injecting medical liquid operation, not only significantly increase the labor intensity of medical personnel, and, also can because of the malleation in sealed container, when causing injecting medical liquid complete, still having a small amount of medicinal liquid stays in the liquid-conveying ducts of piercing needle, in time extracting piercing needle, medicinal liquid in liquid-conveying ducts will water clock, not only cause the waste of medicine, simultaneously, also to make dirty sealed container, during operation, finger coordinates bad, the medicinal liquid injected in sealed vial oppositely can push back syringe, cause waste and configure medicament precision not high, when taking out medicinal liquid operation, because the space inside sealed container has been hermetic, negative pressure can be formed in sealed container, and along with the medicinal liquid extracted out more, its pressure is larger, needs medical personnel to use more strength just can complete to take out medicinal liquid to operate, not only significantly increase the labor intensity of medical personnel, during operation, finger coordinates bad, and the medicinal liquid in suction syringe oppositely can push back ampoule, causes waste and configure medicament precision not high.
Further, along with the develop rapidly of present automatic technology, intravenous administration dosing operation can realize full-automatic realization, but when sealed container forms malleation or negative pressure, its dose control accuracy will become and more be difficult to control.
Summary of the invention
For above deficiency, the invention provides a kind of structure simple, easy to operate, pharmaceutical quantities control accuracy is higher, avoid the intravenous administration dosing needle set of dropping liquid phenomenon completely, it comprises piercing needle and needle stand, the left end of described piercing needle is provided with the first fluid apertures, its right-hand member is provided with the second fluid apertures, described needle stand is also provided with trocar sheath, described piercing needle is arranged in the pipeline of described trocar sheath, the pipeline of trocar sheath is stretched out at the two ends of piercing needle respectively, first fluid apertures is positioned at extension on the left of it, air guide channel is formed between the outer wall of piercing needle and trocar sheath, the left end of trocar sheath is also provided with and can stretches in sealed container and the first pore be connected with described air guide channel, the right-hand member of trocar sheath is provided with and exposes outside sealed container and the second pore be connected with described air guide channel.
In order to realize the present invention further, the left end of described piercing needle arranges sharp-pointed portion, and the left end sidewall of piercing needle is provided with described first fluid apertures.
In order to realize the present invention further, the left end end of described trocar sheath is formed with the introduction part of truncated cone-shaped, and the left end of introduction part is small end.
In order to realize the present invention further, the installing hole that the intermediate formation of described needle stand has left and right through, the right-hand member of described trocar sheath is fixedly mounted in the installing hole of needle stand, and the position corresponding to the second pore of needle stand is provided with the passage with its conducting.
In order to realize the present invention further, the right-hand member of described needle stand is provided with the union joint facilitating catheter to connect fast.
Beneficial effect of the present invention:
1, intravenous administration dosing needle set of the present invention utilizes the structure of double-jacket tube to form separate liquid-conveying ducts and air guide channel respectively, when carrying out injecting medical liquid to sealed container and take out the operation of medicinal liquid, utilize air guide channel can pressure automatically in Fast-Balance sealed container, make at injecting medical liquid with when taking out medicinal liquid, pressure in sealed container is consistent all the time with its external pressure, greatly reduces the labor intensity of medical personnel or power-equipment; In addition, because the pressure in sealed container is balanced, at stopping injecting medical liquid with when taking out medicinal liquid, the infusion channel of piercing needle can not leave over medicinal liquid, can not cause waste, more can not water clock to surrounding place, avoid dropping liquid phenomenon completely.
2, the left end end of trocar sheath of the present invention is formed with the introduction part of truncated cone-shaped, facilitates it to penetrate serum cap.
