Abstract
The utility model discloses the jack rod sleeve of a kind of band 3 reinforcements.Jack rod sleeve is provided with 3 reinforcements, bottle base is provided with corresponding draw-in groove simultaneously.Reinforcement on jack rod sleeve can insert the draw-in groove on bottle base, then coordinates medical apparatus and instruments glue special, and jack rod sleeve is fixed on bottle base.This fixing means is easy, by the engagement between reinforcement and draw-in groove, effectively prevents the loosening of jack rod sleeve, swing even slippage.
Description
Technical field
This utility model relates to clinical transfusion field, particularly relates to the jack rod sleeve that single use infusion pump is applied.
Background technology
Single use infusion pump Major Clinical is applied to postoperative injection analgesic, the tension force adopting silica gel reservoir is energy and power, flow is controlled by microporous pipe, select suitable specification and analgesic by doctor thus reach releasing or lenitive single use medical apparatus and instruments, being applicable to vein epidural space and subcutaneous micro-administered by infusion function.Single use infusion pump reservoir assembly comprises silica gel reservoir, silica gel ring, jack rod sleeve and slide bar composition.During assembling, slide bar is inserted litter cover, then put silica gel reservoir, recycle silicon rubber sealing, thus form the sealing silica gel reservoir of a silica gel reservoir parcel.Silica gel reservoir assembly is fixed on bottle base by jack rod sleeve.When injecting analgesic in reservoir assembly, silicon capsule expands, and band moving slide-bar skids off.
The fixing of jack rod sleeve generally adopts the way fastened with glue, but firm pasting degree usually can not meet the demands, and easily cause jack rod sleeve to loosen when injection of medicine, swing even slippage, thus affects the use of infusion pump.
Utility model content
Technical problem to be solved in the utility model is to provide the jack rod sleeve of a kind of band 3 reinforcements, makes the fixing more firm of jack rod sleeve, thus ensures the normal use of infusion pump.
This utility model is that to solve the problems of the technologies described above the technical scheme of employing as follows:
The bonding site of the jack rod sleeve of single use infusion pump is designed with three reinforcements, and these three reinforcements and jack rod sleeve form an entirety by injection moulding.Meanwhile, have three draw-in grooves in the bonded part respective design of infusion pump bottle base and jack rod sleeve, these three draw-in groove sizes are corresponding with the reinforcement size of three on jack rod sleeve, ensure that jack rod sleeve can insert bottle base completely and coordinate closely.
When the jack rod sleeve of said structure and bottle base are fixed, first the bonding site of jack rod sleeve is comprised three reinforcements and evenly coat medical apparatus and instruments glue special, then, jack rod sleeve is inserted bottle base.During insertion, the reinforcement correspondence on jack rod sleeve is inserted the draw-in groove of bottle base, coordinate closely, then make glue curing by correlation method, namely complete the fixing of jack rod sleeve.
The jack rod sleeve of above-mentioned band 3 reinforcements effectively prevent swinging of jack rod sleeve, also can increase the cooperation firmness of jack rod sleeve and bottle base, coordinates medical apparatus and instruments glue special, and what effectively can prevent jack rod sleeve loosens even slippage.This fixing means is simple, rationally, easily manufactured, and serviceability is high, is a kind of single use infusion pump jack rod sleeve of novelty.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the design diagram of the jack rod sleeve of this utility model band 3 reinforcements.
In figure: 1: reinforcement
2: jack rod sleeve
Detailed description of the invention
Fig. 1, Fig. 2 give the jack rod sleeve of band 3 reinforcements, comprise reinforcement 1, jack rod sleeve 2.Time fixing, the bonding end of the jack rod sleeve 2 shown in Fig. 1 is comprised reinforcement 1 and coats medical apparatus and instruments glue special, then, jack rod sleeve 2 with medical apparatus and instruments glue special is inserted the draw-in groove of bottle base, press down make jack rod sleeve 2 and bottle base engagement tight, make glue curing by correlation method again, namely complete the fixing of jack rod sleeve.This fixing means is easy, by the engagement between reinforcement 1 and draw-in groove, effectively prevents the loosening of jack rod sleeve, swing even slippage.
During use, analgesic injects silica gel reservoir by the jack rod sleeve be fixed on bottle base, the analgesic injected makes silica gel reservoir expand, promote sliding bar, now, because jack rod sleeve is fixed on bottle base, thus effectively secure silica gel reservoir assembly, ensure that the infusion of drug function of infusion pump.
Claims (1)
1. be with a jack rod sleeve for 3 reinforcements, the bonding end of jack rod sleeve is provided with 3 reinforcements, it is characterized in that:
The reinforcement that jack rod sleeve designs can insert on bottle base in corresponding draw-in groove, and closely cooperates, and by the engagement between reinforcement and draw-in groove, effectively prevents the loosening of jack rod sleeve, swing even slippage, play the effect of fixed slip bar cover.
