Description
Technical field
This utility model relates to transfusion bag, particularly two-tube pair of diaphragm PP transfusion bag.
Background technology
In clinical treating disease, often give patient infusion or pass through intravenous drip directly by infusion of medicine body.Transfusion bag or infusion bottle are suspended on support, air inlet needle connects trachea, be power by liquid gravity at ambient pressure, air is made to enter infusion bottle from air inlet pipe, air inlet needle, but such structure as power, utilizes atmospheric pressure by liquid gravity, liquid is extruded in transfusion needle, its power is little, can not accurately control transfusion speed and amount of infusion.In transfusion bag or infusion bottle, air enters from air inlet needle from outside, and medicinal liquid is easily polluted.
Existing transfusion bag, except above-mentioned defect, also has following defect: (1), the dosing mouth of pipe are too thin, when dosing, may, due to misoperation, cause chemical feed pipe to break, cause infusing unsuccessfully, if chemical feed pipe is too thick, then increase cost; (2), dosing base and transfusion base adopt integral structure be arranged at transfusion bag inside, easily the phenomenon of leakage occurs, reliability is poor; (3), chemical feed pipe and tube for transfusion before use, the mouth of pipe exposes with air, and bag inner liquid medicine is easily polluted; (4), infusion tube structure is unreasonable, causes medicinal liquid to flow out thorough, or needs by external pressure so that medicinal liquid is extruded bag.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of leakage rate is low, safe and reliable, cost is low, can prevent chemical feed pipe from breaking and medicinal liquid flows out two-tube pair of diaphragm PP transfusion bag thoroughly.
The purpose of this utility model is achieved through the following technical solutions: two-tube pair of diaphragm PP transfusion bag, it comprises body and is arranged at the hanging hole of bodies top, it also comprises dosing interface block, infusion connector seat, chemical feed pipe and tube for transfusion, described dosing interface block and infusion connector seat are divided into the two bottom sides of body, chemical feed pipe and dosing interface block integrally welded, tube for transfusion and infusion connector seat integrally welded, the lower surface of chemical feed pipe and tube for transfusion is all pasted with seal membrane.
Described dosing interface block and the outside of infusion connector seat are provided with reinforcement.
Described chemical feed pipe is divided into the heavy wall section, changeover portion and the thin segment that are connected successively, and the lower end wall thickness of changeover portion is identical with the wall thickness of heavy wall section, and the upper end wall thickness of changeover portion is identical with the wall thickness of thin segment.
The nozzle diameter of described tube for transfusion near tube for transfusion interface block side is greater than the nozzle diameter away from tube for transfusion interface block side.
This utility model has the following advantages:
1, dosing interface block and infusion connector seat are divided into the two bottom sides of body, reduce leakage rate, the outside of dosing interface block and infusion connector seat is provided with reinforcement, increase the intensity of dosing interface block and infusion connector seat, prevent in dosing or infusion process, dosing interface block and infusion connector seat break or damage phenomenon, improve infusion safety.
2, chemical feed pipe adopts the pipe structure of upper-thin-lower-thick, both can reduce waste of material, thus reduce costs, and can prevent again the chemical feed pipe caused when dosing from breaking, the thickness structure of chemical feed pipe science, rationally more.
3, tube for transfusion adopts up big and down small structure, serves pressurization when infusing, and is convenient to transfusion and normally carries out, medicinal liquid is flowed out more thorough.
4, be all pasted with seal membrane at the lower surface of chemical feed pipe and tube for transfusion, can effectively prevent the impurity in extraneous air from entering chemical feed pipe and tube for transfusion, during use, seal membrane of only need tearing, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of chemical feed pipe;
In figure: 1-body, 2-hanging hole, 3-chemical feed pipe, 4-tube for transfusion, 5-seal membrane, 6-dosing interface block, 7-infusion connector seat, 8-reinforcement, 9-heavy wall section, 10-thin segment, 11-changeover portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, two-tube pair of diaphragm PP transfusion bag, it comprises body 1 and is arranged at the hanging hole 2 at body 1 top, it also comprises dosing interface block 6, infusion connector seat 7, chemical feed pipe 3 and tube for transfusion 4, described dosing interface block 6 and infusion connector seat 7 are divided into the two bottom sides of body 1, chemical feed pipe 3 is integrally welded with dosing interface block 6, tube for transfusion 4 is integrally welded with infusion connector seat 7, the lower surface of chemical feed pipe 3 and tube for transfusion 4 is all pasted with seal membrane 5, can effectively prevent the impurity in extraneous air from entering chemical feed pipe 3 and tube for transfusion 4, during use, only need to tear seal membrane 5, simple to operate.
Further, described dosing interface block 6 and the outside of infusion connector seat 7 are provided with reinforcement 8, increase the intensity of dosing interface block 6 and infusion connector seat 7, prevent in dosing or infusion process, dosing interface block 6 and infusion connector seat 7 break or damage phenomenon, improve infusion safety.
Further, as shown in Figure 2, described chemical feed pipe 3 is divided into the heavy wall section 9, changeover portion 10 and the thin segment 11 that are connected successively, the lower end wall thickness of changeover portion 10 is identical with the wall thickness of heavy wall section 9, and the upper end wall thickness of changeover portion 10 is identical with the wall thickness of thin segment 11, and dosing needle tubing coordinates with heavy wall section 9, both can effectively prevent in dosing process, there is fracture phenomena in chemical feed pipe 3, can reduce waste of material again, reduces production cost.
Further, the nozzle diameter of described tube for transfusion 4 near tube for transfusion interface block 7 side is greater than the nozzle diameter away from tube for transfusion interface block 7 side, when medicinal liquid flows out from tube for transfusion 4, adopt up big and down small structure to serve pressurization, be convenient to transfusion and normally carry out.
