Abstract
The utility model discloses a micro flow infusion controller, which comprises a plastic main body and a metal wire, wherein the medal wire passes through the plastic main body, and a micro flow channel is arranged between the plastic main body and the metal wire. After adopting the technical scheme, the micro flow infusion controller has the beneficial effects that the micro flow infusion controller forms the micro flow channel between the plastic main body and the metal wire, produces by adopting an injection molding mode, and forms the needed micro flow channel by utilizing different contractibility rate of plastics and metal wires, thereby greatly reducing production difficulty, and increasing rate of finished products.
Description
Technical field:
This utility model relates to a kind of micrometeor transfusion controller.
Background technology:
In the modern medicine, when patient was implemented infusion treatment, some injection was that requirement carries out carrying out constantly for a long time the trace transfusion to patient; The trace transfusion is to utilize micrometeor transfusion controller to carry out the control of injection flow; Traditional micrometeor transfusion controller is a body that runner is very little, produces this body and carries out through expressing technique, because the micrometeor channel size is very thin; Requirement to the die size precision is very high; Cause manufacturing cost high, yield rate is very low, and the mount difficulty.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, provides a kind of and is easy to make, yield rate is high, the micrometeor transfusion controller little to technological requirement, and the production technology of producing this controller.
The purpose of this utility model can realize through following technical scheme: a kind of micrometeor transfusion controller, include plastic body and tinsel, and tinsel passes plastic body, between plastic body and tinsel, is provided with the micrometeor duct.
Produce the production technology of micrometeor transfusion controller; Its step is following: a. is at the unsettled placement tinsel of dies cavity; B. toward the interior injection of plastic molding of die cavity, c. cools off mould, and the plastic cool in the die cavity is shunk; The tinsel constancy of volume forms the micrometeor duct between plastic body and the tinsel.
After adopting the present technique scheme; The beneficial effect of this utility model is: through forming the micrometeor duct between plastic body and the tinsel; Adopt injection molding mode to produce, utilize plastics and different shrinkage factors wiry, form required micrometeor duct; Can reduce the difficulty of production greatly, improve yield rate.
Description of drawings:
Fig. 1 is the structural representation of this utility model micrometeor transfusion controller;
Fig. 2 is for producing the structural representation of this micrometeor transfusion controller first step;
Fig. 3 is for producing this micrometeor transfusion structural representation in second step of controller;
Fig. 4 is for producing this micrometeor transfusion structural representation in the 3rd step of controller;
Fig. 5 is for producing this micrometeor transfusion structural representation in the 4th step of controller;
Fig. 6 is the structural representation of disposable sterilized pressure transducer;
The specific embodiment:
Below in conjunction with accompanying drawing present technique is described further.
The micrometeor transfusion controller (structure is as shown in Figure 1) of present embodiment includes plastic body 1 and tinsel 2, and tinsel 2 passes plastic body 1, between plastic body 1 and tinsel 2, is provided with micrometeor duct 3.
Produce the production technology of micrometeor transfusion controller, its step is following: a. places tinsel 2 on the counterdie 4 of mould, as shown in Figure 2; B. close patrix 5 and counterdie 4, patrix 5 forms die cavity 6, the tinsel 2 unsettled die cavitys 6 that pass together with counterdie 4; As shown in Figure 6, c. is toward die cavity 6 interior injection of plastic molding, and is as shown in Figure 4; D. mould is cooled off, tinsel 2 constancies of volume are shunk in plastic body 1 cooling in the die cavity 6; Form micrometeor duct 3 between plastic body 1 and the tinsel 2, as shown in Figure 5.
The existing structure that is equipped with the disposable sterilized pressure transducer of this micrometeor transfusion controller for example; As shown in Figure 6; Include joint 7, flushing valve (being above-mentioned plastic body) 1, stainless steel silk 2, sealing silica gel 8 and pick off 9, sealing silica gel 8 is connected between joint 7 and the pick off 9, and flushing valve 1 is fixed on the sealing silica gel 8; Stainless steel silk 2 passes flushing valve 1, is formed with micrometeor duct 3 between flushing valve 1 and the stainless steel silk 2.Reach from the purpose of joint 7 to pick off 9 inner micrometeor input medicinal liquids.
The above only is the preferred embodiment of this utility model, is not this utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under this utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to this utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from this utility model technical scheme, the equivalence of doing according to shape, structure and the principle of this utility model changes, and all should be covered by in the protection domain of this utility model.
