In order to solve the technical problem, the utility model provides a following technical scheme: a medicine grinding injector comprises a medicine charging hollow cylinder, a grinding hollow cylinder and a grinding shaft, wherein the medicine charging hollow cylinder is sleeved outside the grinding hollow cylinder; the grinding hollow cylinder is fixedly connected with a first piston, the outer wall of the first piston is in sliding connection with the inner wall of the charging hollow cylinder, the grinding shaft is fixedly connected with a second piston, and the outer wall of the second piston is in sliding connection with the inner wall of the grinding hollow cylinder; the end part of one end of the grinding hollow cylinder, which is positioned in the charging hollow cylinder, is provided with a grinding disc, the grinding disc is provided with a plurality of through holes, one end of the charging hollow cylinder, which is close to the grinding disc, is provided with a suction head, and the suction head is communicated with the charging hollow cylinder.
The utility model discloses a theory of operation and beneficial effect thereof:
when the medicine grinding injector in the scheme is used, the second piston is fixedly connected to the grinding shaft, the outer wall of the second piston is in sliding connection with the inner wall of the grinding hollow cylinder, the length of the grinding shaft is larger than that of the grinding hollow cylinder, one end, located outside the grinding hollow cylinder, of the grinding shaft is held by a hand, the grinding shaft is pulled out, then medicine to be ground is placed on a grinding disc on the grinding hollow cylinder, the grinding shaft is placed in the grinding hollow cylinder, the grinding shaft is rotated, the medicine is ground through friction and extrusion between the grinding shaft and the grinding disc, through holes are formed in the grinding disc, the ground medicine enters the medicine containing hollow cylinder through the through holes in the grinding disc, after the medicine is completely ground, when the medicine liquid needs to be configured, a suction head on the medicine containing hollow cylinder is in contact with the liquid needed by the configuration of the medicine liquid, and the first piston is fixedly connected to the grinding hollow cylinder, the outer wall of the first piston is connected with the inner wall of the medicine charging hollow cylinder in a sliding mode, so that when the grinding hollow cylinder is pulled, liquid required by medicine liquid preparation enters the medicine charging hollow cylinder through the suction head and is mixed with ground medicines.
At the moment, the grinding disc and the grinding shaft are provided with a plurality of residual medicines, then the grinding shaft is pulled, so that the liquid medicine in the medicine containing hollow cylinder enters the grinding hollow cylinder, after the liquid medicine is mixed with the medicines on the grinding disc and the grinding shaft, the grinding shaft is pushed, the liquid medicine in the grinding hollow cylinder is pushed into the medicine containing hollow cylinder together, and the configuration of the medicines can be completed. When this scheme of adoption carries out medicine grinding and liquid medicine configuration, compare prior art, the effectual waste that reduces the medicine, this syringe is disposable moreover, and then has avoided the medicine to mix and has caused the influence to the patient, need not change the apparatus simultaneously for operation process is simpler, has improved work efficiency.
Furthermore, a plurality of protrusions are arranged at the end part of one end, close to the grinding disc, of the grinding shaft. The friction force is increased, and the grinding speed of the medicine is improved.
Furthermore, a sealing cover is arranged on the suction head. Effectively preventing the medicine from leaking out of the sucker in the grinding process.
Furthermore, a plurality of anti-skid grains are arranged on the grinding shaft. The effectual in-process hand that has prevented to pull grinding shaft removal and the grinding shaft between appear skidding.
Drawings
Fig. 1 is a schematic structural view of the drug grinding syringe of the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: grinding shaft 1, anti-skidding line 2, grinding empty cylinder 3, powder charging empty cylinder 4, first piston 5, second piston 6, protrusion 7, through-hole 8, suction head 9, sealed lid 10.
The embodiment example is shown in the attached figure 1:
a medicine grinding injector comprises a medicine charging hollow cylinder 4, a grinding hollow cylinder 3 and a grinding shaft 1, wherein the medicine charging hollow cylinder 4 is made of transparent materials, the grinding hollow cylinder 3 is sleeved outside the grinding hollow cylinder 3, the grinding hollow cylinder 3 is sleeved outside the grinding shaft 1, the length of the grinding hollow cylinder 3 is greater than that of the medicine charging hollow cylinder 4, and the length of the grinding shaft 1 is greater than that of the grinding hollow cylinder 3; a first piston 5 is bonded or glued on the grinding hollow cylinder 3, the first piston 5 is annularly arranged on the outer wall of the grinding hollow cylinder 3, the outer wall of the first piston 5 is slidably connected with the inner wall of the charging hollow cylinder 4, a second piston 6 is bonded or glued on the grinding shaft 1, the second piston 6 is annularly arranged on the side wall of the grinding shaft 1, and the outer wall of the second piston 6 is slidably connected with the inner wall of the grinding hollow cylinder 3; the tip that grinds the one end that empty section of thick bamboo 3 is located the empty section of thick bamboo of powder charge 4 bonds or is glued there is the abrasive disc, is equipped with a plurality of through-holes 8 on the abrasive disc, and the one end that the empty section of thick bamboo of powder charge 4 is close to the abrasive disc bonds or is glued there is suction head 9, and suction head 9 and the empty section of thick bamboo of powder charge 4 intercommunication, and the tip that grinding shaft 1 is close to the one end of abrasive disc bonds or is glued there are a plurality of archs 7, and threaded connection has sealed lid 10 on the suction head 9, bonds or is glued.
