Abstract
The invention discloses a preparation method of a disposable infusion pump flow-limiting tube. The preparation method comprises the processes of pellet material heating, melting, extrusion, cutting, drawing, classification and pairing, wherein the extrusion process comprises extruding the molten materials together with a steel wire with an external diameter of 8, extracting the steel wire after an extruded tube is formed and performing the classification and the pairing; the classification and pairing process is characterized in that, according to indicating marks, flow-limiting tubes of different pressures are classified into five grades, according to different measured pressures, reservoirs are classified into five grades, and then the flow-limiting tubes of different grades are paired with the reservoirs of the corresponding grades, accordingly preparation of the flow-limiting tubes can be completed.
Description
Technical field
The present invention relates to clinical transfusion field, particularly relate to the preparation method of the current limiting tube 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 with micropore current limiting tube, 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.
The flow of single use infusion pump is controlled by micropore current limiting tube.Current limiting tube to be dammed principle by micropore, makes analgesic by evenly, slowly entering in patient body in the current limiting tube of the aperture of 6 ~ 8.But the tension force produced when injecting analgesic due to each silica gel reservoir there are differences, and causes the flow of infusion pump not reach the requirement of product standard, thus affects the use of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method of single use infusion pump current limiting tube, makes infusion pump flow meet the requirement of product standard, ensures the dosage safety of analgesic, thus ensures the normal use of infusion pump.
The present invention is that to solve the problems of the technologies described above the technical scheme of employing as follows:
Current limiting tube preparation technology flow process: material grain heat → melt → extrude → cut → reel off raw silk from cocoons → classify → match, wherein extruding operation is jointly extrude with the steel wire of an external diameter 8.After squeezing pipe, the current limiting tube extruded is cut into 5 kinds of length, extract steel wire wherein out, then carry out classifying and matching.The method of current limiting tube classification is: current limiting tube is inserted current limiting tube classifying instrument, setting pressure, starts current limiting tube classifying instrument, waits after automatically closing, observes indicating graduation, then according to indicating graduation, the current limiting tube of different pressures value is divided into 5 grades.The method of current limiting tube pairing is: the instrument that reservoir assembly pvc pipe and current limiting tube matched is connected, and gas injection 150mL, records pressure according to capsule and reservoir is divided into 5 grades.During pairing, the reservoir of the current limiting tube of different shelves and corresponding shelves is matched, namely completes the preparation of current limiting tube.
Accompanying drawing explanation
Fig. 1 is the current limiting tube schematic diagram of single use infusion pump current limiting tube preparation method of the present invention.
In figure: 1: current limiting tube
2: micropore
Specifically buy the mode of executing
PVC is expected grain heating makes it melt, with the elongated wire coextrusion of external diameter 8, then cut into 5 kinds of length, be respectively 70mm, 75mm, 80mm, 85mm, 90mm, extract the steel wire in every root current limiting tube respectively out, just define the current limiting tube that an internal diameter is 8.Again current limiting tube classified and match.Current limiting tube classifying instrument value of pressure: 0.067Mpa during classification, definite value time 20S, is divided into 5 grades by current limiting tube according to classifying instrument indicating graduation.Gas injection instrument definite value gas injection 3 times during pairing, amount to 150mL gas, gas injection instrument definite value time 29S, records pressure and is divided into 5 grades by capsule, and the capsule pairing of the 5 grades of current limiting tubes then determined classifying and corresponding shelves, namely completes the making of current limiting tube, in table 1.
Table 1 current limiting tube matches
During use, analgesic injects reservoir by dosing mouth, and the pressure that reservoir expansion produces makes medicine flow to patient by current limiting tube.The principle that current limiting tube is dammed by micropore, and by the pairing with reservoir, make medicine at the uniform velocity, slowly can flow to patient, reach the object of dosage safety.
Claims (1)
1. the preparation method of a single use infusion pump current limiting tube, preparation technology's flow process: material grain heat → melt → extrude → cut → reel off raw silk from cocoons → classify → match, wherein extruding operation is jointly extrude with the steel wire of an external diameter 8, steel wire is wherein extracted out after squeezing pipe, then carry out classifying and matching, classification and pairing are characterised in that: according to indicating graduation, the current limiting tube of different pressures value is divided into 5 grades, record pressure according to capsule and reservoir is divided into 5 grades, then the reservoir of the current limiting tube of different shelves and corresponding shelves is matched, namely complete the preparation of current limiting tube.
