The specific embodiment
Fig. 1～Fig. 4 illustrates a kind of Disposable Injection Analgesic Pump, same as the prior art is mainly to comprise medicine storage, filter, flow controller, several parts of conduit and tube for transfusion, described medicine storage connects filter successively by conduit, flow controller and tube for transfusion, and be connected in patient's body by the tube for transfusion liquid outlet of inserting human body, the Disposable Injection Analgesic Pump that this utility model provides is characterised in that above-mentioned medicine storage is to be made of with the elasticity transparent shell 4 that can be attached on the human body elasticity drug storage pipe 1 that can free harmomegathus, drug storage pipe 1 is fixed in the housing 4, the one end is communicated with medicinal liquid by housing feed liquor port 48, the other end is fixedlyed connected with conduit 3 by clip 31, and draws medicinal liquid by conduit 3 from housing 4 fluid ports 47.
Above-mentioned transparent shell 4 is to be made of base plate 44 that can be attached at human body and the transparent casing of fixing on it 43, and its feed liquor port 48 is provided with check valve 2, and above-mentioned drug storage pipe 1 is communicated with medical fluid injector 9 by check valve 2; Above-mentioned flow controller is a flow control tube 6, and the conduit 3 of drawing from housing fluid port 47 is connected with flow control tube 6 by above-mentioned filter 5, and connects tube for transfusion 8 by flow control tube 6.
In the present embodiment, the base plate 44 of above-mentioned transparent shell 4 is a strip, more specifically say and be Long Circle, above-mentioned transparent casing 43 is spiral-lock transparent arch tops on the Long Circle base plate, arch apical ring circumferential edges is provided with installs limit 42, limit 42 is installed to be fixed on the base plate 44 by heat seal or bonding way, be provided with feed liquor port 48 at transparent casing 43 corresponding housing one narrow end, another narrow end of corresponding housing is provided with fluid port 47, housing both sides and base plate 44 are integrally formed with flank 41, flank 41 is semicircle, and above-mentioned splicing tape 45 is fixed on base plate 44 back sides across two flanks 41.Only need take splicing tape surface coverage paper 46 during use off can be attached to housing 4 and dish anesthesia on the splicing tape 45 or analgesic fluid catheter 3 and be adhesively fixed on the human body skin.
Above-mentioned drug storage pipe 1 adopts material such as isoprene rubber or the organic silicon rubber making with superior elasticity, make the drug storage pipe 1 can free wxpansion when injecting medicinal liquid, after injection finishes, can rely on the elastic restoring force that produces after self dilatancy to shrink automatically, so that medicinal liquid is extruded from conduit 3; Shell 4 adopts the elasticity medical plastic, has pliability, is convenient to be installed on the human body.
As Fig. 1, shown in Figure 4, above-mentioned flow control tube is one section control valve 6, and can also be connected by the multistage control valve constitutes.Flow control tube is the trace stream buret of a kind of internal diameter less than 1mm, in the time need selecting different medicinal liquid flow velocitys according to different patient's situations, can reach flow speed control by the flow control tube of selecting different length for use, for ease of the speed adjustment, this utility model has adopted the combination type flow control tube.In the present embodiment, exemplified the applicable cases of one section or two sections flow control tube.Flow control tube 6 is threaded with the tube for transfusion joint 81 of the threaded female joint 62 of tube for transfusion 8 by the screw thread male joint 61 that its termination is provided with, second section flow control tube 7 two ends is respectively equipped with threaded female joint 62 and screw thread male joint 63, when needing, be connected between the joint 81 of flow control tube 6 and tube for transfusion 8 and get final product.By can realizing the control to the flow velocity that injects medicinal liquid being connected of flow control tube 6 and second section flow control tube 7, thereby satisfy the demand of different patients to different medicinal liquid flow velocitys, adjustment easy to use is rapid.
The end that tube for transfusion 8 is inserted human body is the liquid outlet that top seal and ring back down some side openings, in order to medicinal liquid is injected human body; Check valve 2 is commercially available medical devices.
The operation principle and the operating process of the Disposable Injection Analgesic Pump that this utility model provides are as follows:
As shown in Figure 4, during use, adopt syringe 9 by the individual event valve 2 medicinal liquid injection drug storage pipe 1 of will anaesthetizing or ease pain, drug storage this moment pipe 1 is along with the injection of medicinal liquid, can expand gradually, be can be not effusive from check valve owing to adopted check valve 2, the medicinal liquid in the drug storage pipe 1.Drug storage pipe 1 is because dilatancy can produce certain recovery contractility by its elasticity, under the effect of this contractility, in the conduit 3 that medicinal liquid is extruded into drug storage pipe 1 is connected, and by in conduit 3 inflow filters 5, medicinal liquid can filter out wherein micro-bubble by filter 5 and flow in the flow control tube 6.Flow control tube 6 is connecting tube for transfusion 8, and the liquid outlet that makes medicinal liquid pass through tube for transfusion 8 injects human body; Be connected with second section flow control tube 7 as flow control tube 6, then medicinal liquid enters tube for transfusion 8 again by second section flow control tube 7 earlier, injects human body by tube for transfusion 8 liquid outlets then.By can realizing control being connected of flow control tube 6 and second section flow control tube 7, thereby can select different medicinal liquid flow velocitys, reach better pain relieving purpose according to different patient's situations to the flow velocity that injects medicinal liquid.
As shown in Figure 6, the Disposable Injection Analgesic Pump is after injecting medicinal liquid, covering paper 46 on the splicing tape 45 at base plate 44 back sides can be torn, and conduit 3 dish is folded to appropriate length be pressed in below the splicing tape, then splicing tape is directly sticked on the skin of human body 10, after treating that medicinal liquid flows out normally from tube for transfusion 8 liquid outlets, tube for transfusion 8 liquid outlets are inserted in the human body, and fix with medical rubber cream.
The above only is a preferred embodiment of the present utility model, is not shape material of the present utility model and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
