Abstract
The utility model relates to a buffer push head of an intravenous injection booster, and belongs to the technical field of medical instruments. The buffer push head is composed of a clamping head, a buffer spring, a clamping head seat and a spring fixing seat. The clamping head is sleeved with the clamping head seat, the buffer spring is arranged at the position, on one side of the clamping head, of the clamping head seat through a fixedly-arranged spring fixing seat, and one end of the buffer spring is connected with the clamping head. When the buffer push head of the intravenous injection booster is used, the push force acting on an injector by the clamping head can be buffered through the buffer spring, the intravenous injection booster has a buffer process in the initial push and injection process, and the problem that an existing intravenous injection booster lacks a buffer process in the initial push and injection process, and pain is extremely prone to being caused to a patient is solved. The buffer push head of the intravenous injection booster has the advantages of being simple in structure, good in practicality and low in cost, and is especially suitable for being mounted and used by the intravenous injection booster.
Description
Technical field
This utility model relates to a kind of buffering of intravenous injection aid cuts somebody's hair, and belongs to technical field of medical instruments.
Background technology
In hygiene medical treatment unit, intravenous injection is one of conventional Therapeutic Method, and no matter internal medicine, surgery, department of pediatrics, oncology etc., all can relate to intravenous injection.At present when carrying out intravenous injection, be mainly by artificial slowly, inject to constant speed, because intravenous injection pharmaceutical quantities is large, injection process is for up to dozens of minutes, causes labor intensity of operating staff large, easily produce tired, and bad grasp of the time of injecting.For addressing this problem, in hygiene medical treatment unit, be all to complete intravenous injection process by intravenous injection aid at present.This intravenous injection aid has utilized screw rod transmission principle well, although can realize, automatically inject, but on intravenous injection aid push rod to cut somebody's hair with syringe be rigid connection, inject cut somebody's hair when initial and syringe between lack the process of a buffering, suddenly inject very easily and cause suffering to patient, the medicine that particularly the high-carbohydrate medicinal liquid coefficient of viscosity is large this situation when injecting is particularly outstanding.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practicality is good, take solve existing intravenous injection aid to cut somebody's hair with syringe be rigid connection, injecting the process that lacks a buffering when initial, very easily to the cause suffering buffering of the intravenous injection aid of cutting somebody's hair with buffering of problem of patient, cutting somebody's hair.
The technical solution of the utility model is:
A kind of buffering of intravenous injection aid is cut somebody's hair, it consists of dop, buffer spring, dop seat and spring fixed seat, it is characterized in that: in dop seat, be set with dop, in the dop seat of dop one side, by the spring fixed seat being fixedly installed, buffer spring is installed, one end of buffer spring is connected with dop; Described dop termination is provided with groove.
This utility model beneficial effect is compared with prior art:
The buffering of this intravenous injection aid is cut somebody's hair while using, by buffer spring available buffer dop, act on the thrust on syringe, make it inject the process that makes it have a buffering when initial, solve existing intravenous injection aid and injected the process that lacks a buffering when initial, the problem very easily causing suffering to patient.The buffering of this intravenous injection aid is cut somebody's hair and is had feature simple in structure, that practicality good and cost is low, is specially adapted to intravenous injection aid and installs and uses.
Accompanying drawing explanation
Fig. 1 is the perspective view that buffering of the present utility model is cut somebody's hair;
Fig. 2 is the sectional structure schematic diagram that buffering of the present utility model is cut somebody's hair.
In figure: 1, dop, 2, buffer spring, 3, dop seat, 4, spring fixed seat, 5, groove.
The specific embodiment
The buffering of this intravenous injection aid is cut somebody's hair and is consisted of dop 1, buffer spring 2, dop seat 3 and spring fixed seat 4.In dop seat 3, be set with dop 1, in the dop seat 3 of dop 1 one sides, by the spring fixed seat 4 being fixedly installed, buffer spring 2 be installed, one end of buffer spring 2 is connected with dop 1 contact; The termination of dop 1 is provided with groove 5.
The buffering of this intravenous injection aid is cut somebody's hair and is fixedly mounted on the push rod of intravenous injection aid by dop seat 3, during use, the bar of injecting of syringe is installed in the buffering groove 5 of cutting somebody's hair, to prevent slippage in bolus infusion processes.In bolus infusion processes, first the thrust of intravenous injection aid act on buffer spring 2 by dop seat 3, and then progressively act on dop 1.Due to the effect of buffer spring 2, the suffered thrust of dop 1 is progressively to become large by little, and buffer spring 2 progressively compressed, and when buffer spring 2 is compressed to limit, dop 1 is that the bar of injecting of pushing syringe advances, until constant speed has been injected.Thereby solved thus on its push rod of existing intravenous injection aid to cut somebody's hair with syringe be rigid connection, inject cut somebody's hair when initial and syringe between lack the process of a buffering, inject suddenly the problem very easily causing suffering to patient.The buffering of this intravenous injection aid is cut somebody's hair and is had feature simple in structure, that practicality good and cost is low, is specially adapted to intravenous injection aid and installs and uses.
