Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of disposable use retaining needle type infusion apparatus.
Background technology
We know that disposable infusion set is the medical apparatus and instruments of using always, and it generally comprises wears a bottle pin, dropping funnel, fluid flow regulator, liquid medicine filter, joint, by transfusion catheter they is chained together.Infusion flow is regulated control by fluid flow regulator, and liquid medicine filter generally is made up of upper and lower casing and microporous filter membrane purifying layer, and the microporous filter membrane purifying layer is clipped between the infundibulate upper and lower casing, and medicinal liquid is filtered, purifies.When manipulating, connect a puncture transfusion draw point by joint and connecting leg.Because tough and tensile puncture transfusion draw point is inserted in patient's vein blood vessel, has limited the activity at patient's contact pin position greatly; After the transfusion, extract transfusion needle pin mouth place misoperation, can cause the blood extravasation of blood vessel, cause inflammation.Continuous several times often causes the clinical complication of transfusion.Therefore, medical personnel's operation of being careful clinically is to guarantee transfusion safety.And venous detaining needle is extensive use of at present, venous detaining needle claims the trocar again, simple to operate with it, sleeve pipe is soft, sleeve pipe is long and be difficult for wearing out the blood vessel characteristics and be widely used at the intravenous indwelling time, when indwelling tube places vein, indwelling tube promptly can still can freely move the injection site with the vein complications, does not have the anxiety of thorn perforating veins, sense of discomfort when having more the safety of use and reducing use is especially being brought into play important function aspect rescue critical patient and the intravenous nutrition.Mainly include remaining needle sleeve pipe, casing seat, puncture needle, connecting leg, infusion connector etc. on the venous indwelling needle construction, sleeve pipe rear end adapter sleeve base, sealing-plug also is housed in the casing seat, puncture needle was inserted sealing-plug hermetically, in remaining needle sleeve pipe and casing seat, the casing seat side direction is connected with infusion connector by connecting leg.Indwelling casing tube places vein to use repeatedly.
And do not see disposable retaining needle type infusion apparatus in the market.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure is provided, operation, easy to use, traditional transfusion device and venous detaining needle reasonable combination, disposable use retaining needle type infusion apparatus with venous detaining needle characteristics.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of disposable use retaining needle type infusion apparatus, comprise wearing a bottle pin, dropping funnel, flow regulator, liquid medicine filter, they being chained together of band air filter by transfusion catheter, it is characterized in that: the liquid medicine filter lower end connects a dosing threeway assembly, and dosing threeway assembly connects a venous detaining needle by connecting leg.
Venous detaining needle of the present invention includes remaining needle sleeve pipe, casing seat, puncture needle tubing, connecting leg, sleeve pipe rear end adapter sleeve base, sealing-plug is housed in the casing seat, the puncture needle tubing was inserted sealing-plug hermetically, in remaining needle sleeve pipe and casing seat, the casing seat side direction is provided with hose coupler, is connected with dosing threeway assembly by connecting leg.
The present invention is owing to connect a venous detaining needle on traditional transfusion device, disposable use, against existing technologies, its simple structure, combination rationally connect reliable, operation, easy to use has the venous detaining needle characteristics, is a kind of ideal disposable use retaining needle type infusion apparatus.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention;
1. wear a bottle pin protective sleeve among the figure, 2. wear a bottle pin, 3. air filter; 4. conduit, 5. dropping funnel, 6. flow regulator; 7. liquid medicine filter, 8. calparine cap, 9. dosing threeway assembly; 10. connecting leg, 11. clips, 12. needle handles; 13. sealing-plug, 14. casing seats, 15. sleeve pipes; 16. the puncture needle tubing, 17. sheaths, 18. hose couplers.
The specific embodiment
As can be seen from Figure 1, a kind of disposable use retaining needle type infusion apparatus of the present invention, what comprise band air filter 3 wears bottle pin 2, dropping funnel 5, flow regulator 6, liquid medicine filter 7 etc., they is chained together the transmission of infusing by transfusion catheter 4.Wear bottle pin 1 and be provided with band air filter 3, can adopt split to mould the pin type, also can adopt integral body to mould the pin type, can also adopt two draw point structures, its effect is to insert in the infusion vessel, wears bottle pin 2 outsides and is provided with and wears a bottle pin protective sleeve 1.Dropping funnel 5 is used for observing medicinal liquid flow, and fluid flow regulator 6 is used for regulating, the control medicinal liquid flow.Liquid medicine filter 7 is used for the impurity in the filtering medicinal liquid.The structure of above-mentioned parts and effect and prior art are basic identical, do not describe in detail.
Characteristics of the present invention are: liquid medicine filter 7 lower ends connect a dosing threeway assembly 9, and dosing threeway assembly 9 connects a venous detaining needle by connecting leg 10.
Venous detaining needle of the present invention includes remaining needle sleeve pipe 15, casing seat 14, puncture needle tubing 16, connecting leg 10 etc.The sleeve pipe 15 outer sheaths 17 that are provided with, sleeve pipe 15 rear ends are connected on the casing seat 14, intracavity is equipped with sealing-plug 13 in casing seat 14 back segments, puncture needle tubing 16 was inserted sealing-plug 13 hermetically, in remaining needle sleeve pipe 15 and casing seat 14, casing seat 14 side direction are provided with hose coupler 18, and hose coupler 18 is connected with dosing threeway assembly 9 by connecting leg 10.That is to say that connecting leg 11 1 ends are communicated with remaining needle sleeve pipe 15 by casing seat 14, the other end connects transfusion device dosing threeway 9, like this, but with regard to normal infusion, the medicinal liquid connecting leg 11 of flowing through enters the casing seat ante-chamber through casing seat 14 side direction hose couplers 18 and flows to sleeve pipe 2, enters vein blood vessel at last.The dosing mouth of dosing threeway 9 is provided with nipple and is connected with calparine cap 8, and when carrying out the transfusion of two kinds of medicinal liquids or in addition dosing can enter dosing threeway 9 by calparine cap 8.
On the connecting leg 11 of the present invention clip 12 is housed, when the patient suspended transfusion because of needs, as long as clamp connecting leg 11 with clip 12, transfusion just can take time out to.Unclamp clip 12 when needing to recover transfusion and get final product, the operation simple and convenient.
When the present invention uses, get all the transfusion articles for use ready, the venipuncture of selecting high resilience and being difficult for sliding, thorough disinfection site of puncture skin is got remaining needle and is rotated puncture needle tubing 16 inclined-planes upwards, slowly thrust straightly blood vessel with 15～30 degree angles, see and reduce puncture angle behind the blood back, move back puncture needle tubing 16 in sleeve pipe 15, again sleeve pipe 15 is sent in the blood vessel again along the blood vessel 3～5mm that moves ahead, extract puncture needle tubing 16, just can carry out disposable normal infusion.
