Abstract
The utility model relates to a medical dosage needle, comprising a needle and a connecting base at the back end of the needle, wherein the front end of the needle is a conical sealing structure and a side needle hole is disposed on the back end of the needle close to the connecting base. The needle is equally provided with two to four side needle holes on the circumferential direction and two to five layers of side needle holes on the axial direction. The utility mode has the advantages that the front end of the needle is conical sealing structure and the needle passes through a rubber plug in the manner of wedge so the generated rubber scraps are efficiently decreased and the use is safe. The back end of the needle is disposed with a plurality layer of side needle holes so the liquid medicine in an infusion bottle can be absorbed completely without drawing out the pinhead, the use is convenient and the wastage is efficiently avoided.
Description
Technical field:
This utility model relates to the medical apparatus and instruments of clinical use, particularly a kind of medical syringe needle that makes up a prescription.
Background technology:
When the nursing staff makes up a prescription at present, the suction of liquid when using the injection needles head to carry out the dissolved solid medicine.But when the medicine bottle of pumping liquid or past solid drugs injected, container was to seal with rubber stopper basically, so syringe needle must pass sealing rubber plug.Existing syringe needle seals often scrap gum under regular meeting's thorn passing rubber stopper, and these scrap gums may enter the clarity that can influence medicinal liquid in the medicinal liquid, thereby and the health that might enter harmful to human in the human body by injection; Or retain in the needle tubing and result in blockage, make that medicine is contaminated and waste.
Simultaneously, during the medicinal liquid of existing various powder syringe needles after draw dissolved,, when being inverted medicine bottle and extracting, often can't be drawn into the medicine of bottom, cause the waste of medicine because the position of pin hole is positioned at the forefront of syringe needle; In order to extract this part medicinal liquid, medical personnel generally need extract syringe needle out, the position of pin hole is flushed with the bottleneck of being inverted the back medicine bottle, so just can reach its intended purposes, but operate as easy as rolling off a logly being withdrawn into syringe needle in the rubber stopper or directly extracting medicine bottle out like this, so just caused the secondary pollution of syringe needle also to increase the difficulty of drawing medicinal liquid.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, and a kind of medical syringe needle that makes up a prescription easy to use and safe in utilization is provided.
To achieve these goals, this utility model provides a kind of medical syringe needle that makes up a prescription, and comprises the Connection Block of needle body and needle rear end, and wherein, the front end of described needle body is conical hermetically-sealed construction, and described needle body is provided with the side pin hole near the rearward end of described Connection Block.
Described side pin hole evenly is provided with 2-4 on the circumferencial direction of described needle body, the axial direction of described needle body is provided with the 2-5 layer.
The outstanding advantage of this utility model is: the front end of needle body is conical hermetically-sealed construction, and needle body passes rubber stopper in the mode of wedging, effectively avoids or reduce the generation of scrap gum, and is safe in utilization; The rear end of needle body is provided with the side pin hole, and is provided with multilamellar, and not needing to extract outward syringe needle can be clean, easy to use with the suction of the medicinal liquid in the infusion bottle, effectively avoids waste.
Description of drawings;
Fig. 1 is the overall structure front view of this utility model embodiment.
The specific embodiment:
Design agents mechanism comprised needle body 1, side pin hole 2 and Connection Block 3 when embodiment of the present utility model implemented, wherein, the rear end of needle body 1 is provided with Connection Block 3, and the front end of needle body 1 is conical hermetically-sealed construction, and needle body 1 is provided with side pin hole 2 near the rearward end of Connection Block 3; Side pin hole 2 evenly is provided with two on the circumferencial direction of needle body 1, the axial direction of needle body 1 is provided with two-layer.
