Abstract
The utility model discloses a surgical injector. The surgical injector comprises an injection barrel and a pushing rod which is inserted in the injection barrel by a sealing plug in a sliding manner, wherein a turn plate is fixedly arranged at the outer end of the pushing rod; anti-sliding slots are uniformly distributed in the periphery of the turn plate; an elastic ring, which is matched with the inner wall of the injection barrel in a sliding manner, is fixedly arranged on the middle part of the pushing rod; and threads are formed on the outer ring wall of the elastic ring. The turn plate has two actions of pushing and pulling the pushing rod and rotating the pushing rod. Spiral grains, which have the same in rotary direction as that of the threads, are formed on the middle part of the periphery of the sealing plug. The spiral grains are formed on the middle part of the sealing plug, so that two ends of the sealing plug have a sealing effect, and the middle section of the sealing plug has a feeding function. The surgical injector adopting the structure is reasonable in structure and convenient to use; liquid medicine waste can be avoided; and precise dosing is realized.
Description
Technical field
This utility model relates to a kind of surgery syringe.
Background technology
Syringe is to be used for the utensil of in body injecting fluid.Medically, syringe is the medical appliance that points to injectable drug in the animal body.Traditional syringe mainly comprises injection tube and slides by sealing-plug and is inserted into push rod in the injection tube.In use, the sealing-plug that drives in the injection tube by the push-and-pull push rod moves axially, thereby realizes the function of imbibition and injection, operates very simple.
In order to guarantee that the medicinal liquid in the medicine bottle is sucked in the injection tube fully, generally all can when sucking last medicinal liquid, suck some air in the injection tube, before liquid medicine injection, must again these air be discharged.Because traditional syringe has only the action that advances and pull out push rod, therefore can only the air in the injection tube be extruded by in injection tube, advancing push rod.Because sealing-plug is the sealing that keeps sealing-plug and injection tube inwall by self elasticity, thus sealing-plug when static and the frictional force of injection tube inwall be bigger.When medical personnel increase thrust gradually, and make the power that advances push rod during greater than this frictional force, can not cancel this thrust immediately, just overexert, so not only air can be discharged, also the medicinal liquid in the injection tube can be released, cause liquid waste, also just can not realize accurate administration, be unfavorable for the treatment of the state of an illness.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure at above-mentioned deficiency, can avoid liquid waste, realizes accurate administration, and surgery syringe easy to use.
For solving the problems of the technologies described above, this surgery syringe comprises injection tube and slides by sealing-plug and is inserted into push rod in the injection tube, its construction features is: the push rod outer end is installed with rotating disk, be evenly equipped with anti-slip tank on the rotating disk periphery, the push rod middle part is installed with the elastic ring that is slidingly matched with the injection tube inwall, and the elastic ring external annulus is provided with screw thread.
This surgery syringe is to realize avoiding liquid waste by the swivel feeding structure, realizes accurate administration, and easy to use.
The swivel feeding structure mainly comprises the rotating disk that is installed in the push rod outer end and is installed in the elastic ring at push rod middle part.Rotating disk has two effects, and one is the effect of push-and-pull push rod, and one is the effect of rotation push rod.When rotating rotating disk, rotating disk will drive sealing-plug by push rod and rotate together.Because sealing-plug and the frictional force of injection tube inwall on the sealing-plug tangential direction are very little, so rotary seal plug, the not situation that can occur overexerting very easily.The push rod middle part is installed with elastic ring, and the elastic ring periphery cooperates with injection tube inwall Elastic Sliding.The elastic ring external annulus is provided with screw thread, so does not have sealing relationship between elastic ring external annulus and the injection tube inwall.When rotating disk drove the push rod rotation, push rod also can drive elastic ring and rotate together.At this moment, the screw thread on the elastic ring external annulus applies an axial force that adapts with the screw thread rotation direction will for the injection tube inwall, that is to say or precession, or screws out.Therefore, rotation just can realize promoting sealing-plug axially precession slowly to correct direction, also just can at leisure air be released, and has guaranteed dose, has avoided waste, helps to realize accurate administration.
As improvement, sealing-plug periphery middle part is provided with and the spiral lamination of screw thread with rotation direction.
Because spiral lamination is arranged on sealing-plug middle part, so the sealing-plug two ends still have sealing function, and the sealing-plug stage casing then has feed function.Be provided with to such an extent that rotation direction identical with screw thread on the elastic ring spiral lamination on the sealing-plug, can guarantee both direction of feed unanimities, guaranteed feeding efficient.
In sum, adopt the surgery syringe of this structure, rational in infrastructure, can avoid liquid waste, realize accurate administration, and easy to use.
Description of drawings
In conjunction with the accompanying drawings this utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is injection tube, and 2 is push rod, and 3 is rotating disk, and 4 is anti-slip tank, and 5 is elastic ring, and 6 is screw thread, and 7 is sealing-plug, and 8 is spiral lamination.
The specific embodiment
As shown in the figure, this surgery syringe comprises injection tube 1 and the push rod 2 that is inserted in the injection tube 1, and push rod 2 the inners are installed with the sealing-plug 7 that cooperates with injection tube 1 inwall slipper seal.Push rod 2 outer ends are installed with rotating disk 3, and rotating disk 3 has two effects, and one is the effect of push-and-pull push rod 2, and one is the effect of rotation push rod 2.When rotating rotating disk 3, rotating disk 3 will drive sealing-plug 7 by push rod 2 and rotate together.Because sealing-plug 7 is very little with the frictional force of injection tube 1 inwall on sealing-plug 7 tangential directions, therefore rotary seal plug 7, the not situation that can occur overexerting very easily.Push rod 2 middle parts are installed with elastic ring 5, and elastic ring 5 peripheries cooperate with injection tube 1 inwall Elastic Sliding.Elastic ring 5 external annulus are provided with screw thread 6, so do not have sealing relationship between elastic ring 5 external annulus and injection tube 1 inwall.
When rotating disk 3 drove push rod 2 rotations, push rod 2 also can drive elastic ring 5 and rotate together.At this moment, the screw thread 6 on elastic ring 5 external annulus applies an axial force that adapts with screw thread 6 direction of rotation will for injection tube 1 inwall, that is to say or precession, or screws out.Therefore, rotation just can realize promoting sealing-plug 7 axially precession slowly to correct direction, also just can at leisure air be released, and has guaranteed dose, has avoided waste, helps to realize accurate administration.Rotating disk 3 peripheries are provided with anti-slip tank 4, skid in the time of can avoiding rotating rotating disk, help to realize accurate feeding.
In the present embodiment, sealing-plug 7 peripheries middle part is provided with and the spiral lamination 8 of screw thread 6 with rotation direction.Because spiral lamination 8 is arranged on sealing-plug 7 middle parts, so sealing-plug 7 two ends still have sealing function, and sealing-plug 7 stage casings then have feed function.Be provided with to such an extent that rotation direction identical with screw thread 6 on the elastic ring 5 spiral lamination 8 on the sealing-plug 7, can guarantee both direction of feed unanimities, guaranteed feeding efficient.
