Abstract
The utility model relates to a manual medical pressure-increasing injection booster, which comprises a rapidly replacing bracket composed of a support bracket, a needle head fixing hole arranged at the front end of the support bracket, and a tightly fixing clamp positioned on the support bracket, and a booster body composed of a support connection bracket, a fixing spanner positioned on the back part of the support connection bracket, a pressure increasing spanner hinged with the fixing spanner and a push rod penetrated on the support connection bracket and the fixing spanner. A return spring and a pushing plate are orderly sheathed on a push rod section between the support connection bracket and the fixing spanner. The lower end of the pushing plate is positioned on the front side of a toggling pin arranged on the pressure increasing spanner. An anti-extraction spring and an anti-withdrawal plate are in turn sheathed on the push rod positioned on the back part of the fixing spanner.
Description
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of manual medical supercharging injection booster specifically.
In clinical position, there is the treatment of numerous disease need use syringe.For example, occur keloid easily after patient's wound of scar diathesis, very easily recurrence behind the excision is so need the bound drug therapy that medicine is injected in the cicatrix sometimes; Large-area burns need the Intradermal water filling when the head bark fetching; And for example serious cerebral edema patient sometimes need be with injecting 50% glucose or 20% mannitol dehydration therapy.In these cases, when adopting the normal pressure injecting method, because of resistance is difficult for the pushing syringe piston more greatly, not only easily make medical worker's fatigue when adopting vasopressing injection, pressure is wayward, and injection needle comes off easily, causes overflow of drug fluid, the waste medicine, this problem is perplexing clinical boundary for a long time always.Also there was the scholar to report the development of high hydraulic injector in recent years, but still had undesirable part, as complex structure, inconvenient operation.So the even more ideal manual medical supercharging syringe of development has its practical significance.
The purpose of this utility model provides a kind of simple and reasonable with regard to being to overcome above-mentioned weak point of the prior art, can freely control injection pressure, and volume is small and exquisite, portable manual medical supercharging injection booster.
The purpose of this utility model can adopt following measure to realize:
Manual medical supercharging injection booster of the present utility model comprises quick change support and booster body, and wherein said quick change support is by carriage, is arranged on the syringe needle fixing hole of carriage front end, and the tightening folder that is positioned at the carriage middle part is formed; Described booster body comprises the support and connection frame that is connected with the quick change support by joint bolt and coupling nut, be positioned at the fixed wrench at support and connection frame rear portion, by rotating pin and the hinged supercharging spanner of fixed wrench, and be installed on push rod on support and connection frame and the fixed wrench; Be positioned on the push rod section between support and connection frame and fixed wrench and be set with return spring and pushing plate successively, the lower end of pushing plate be positioned at be provided with on the supercharging spanner stir the pin front side; Be positioned at and be set with anti-extractor and anti-back plate on the push rod at fixed wrench rear portion successively.
The support of quick change described in this utility model comprises three quick change supports that are applicable to 10ml, 20ml, 50ml syringe respectively.
Advantage of the present utility model is:
1, simple in structure, volume is small and exquisite, be easy to carry;
2, the supercharging spanner adopts lever power to learn principle, and convenient manual operation can freely be controlled syringe pressure and injection volume;
3, of many uses, adaptability is strong, is applicable to the syringe of plurality of specifications.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is this utility model user mode axonometric chart.
1 is the syringe needle fixing hole among the figure, the 2nd, and carriage, the 3rd, tightening folder, the 4th, joint bolt and coupling nut, the 5th, preceding push jack, the 6th, return spring, the 7th, pushing plate, the 8th, anti-extractor, the 9th, anti-back plate, the 10th, push rod, the 11st, backboard, the 12nd, stir pin, the 13rd, fixed wrench, the 14th, rotating pin, the 15th, supercharging spanner, the 16th, support and connection frame, the 17th, syringe.
This utility model is done with detailed description below with reference to embodiment (accompanying drawing):
Manual medical supercharging injection booster of the present utility model comprises quick change support and booster body, and wherein said quick change support is by carriage (2), is arranged on the syringe needle fixing hole (1) of carriage front end, and the tightening folder (3) that is positioned at the carriage middle part is formed; Described booster body comprises the support and connection frame (16) that is connected with the quick change support by joint bolt and coupling nut (4), be positioned at the fixed wrench (13) at support and connection frame (16) rear portion, by rotating pin (14) and the hinged supercharging spanner (15) of fixed wrench (13), and be installed on push rod (10) on support and connection frame (16) and the fixed wrench (13); Be positioned on push rod (10) section between support and connection frame (16) and fixed wrench (13) and be set with return spring (6) and pushing plate (7) successively, the lower end of pushing plate (7) be positioned at supercharging spanner (15) go up be provided with stir pin (12) front side; Be positioned on the push rod (10) at fixed wrench (13) rear portion and be set with anti-extractor (8) and anti-back plate (9) successively.Quick change support described in this utility model comprises three quick change supports that are applicable to 10ml, 20ml, 50ml syringe respectively, so range of application is wider.
Operation principle of the present utility model is as follows:
This booster utilizes lever supercharging and friction self-locking principle to carry out.The anti-back plate clamps push rod under the natural situation under the effect of anti-extractor, because the self-locking action push rod of frictional force can only advance, can not retreat.When plate moved the supercharging spanner, slurcam clamped push rod and pushes ahead under the effect of spanner pin and return spring, realized the supercharging injection.Loosen spanner, return spring retreats pushing plate, advances in order to prepare next time, and push rod is because the effect of anti-back plate keeps original position.Injection is pushed anti-back plate bottom after finishing, and push rod is drawn back, and can take out syringe, and prepares next time and use.
The technical problem underlying that this utility model solves is: must implement the supercharging injection, but can use this booster when being inconvenient to use the execute-in-place of large-scale, continuous, electronic supercharging equipment.
