The technical problem to be solved by the utility model is as follows: the indwelling needle type infusion apparatus is provided, the venous indwelling needle can be directly sealed after infusion is finished, saline and an injector do not need to be temporarily prepared, and the working efficiency of medical personnel is improved.
In order to solve the technical problems, the utility model adopts the following technical scheme:
an indwelling needle type infusion apparatus comprises an intravenous indwelling infusion needle, a flow rate regulator, a dropping funnel and a bottle stopper puncture outfit which are sequentially connected in series through an infusion hose; be equipped with the salt solution device on the dropping funnel, the salt solution device includes the salt solution bag, installs the connection hard tube at salt solution bag top and connects hard tube free end cartridge and have and be used for carrying out sealed lid sealed to connecting the hard tube, connects the hard tube pipe diameter and reduces gradually from its link toward its free end, and sealed lid is connected with the dropping funnel.
As a further improvement of the above technical solution:
the saline bag is made of plastic into a gourd shape, is elastic and can be extruded.
Furthermore, a fixed cylinder is communicated between the saline bag and the connecting hard tube, and the sealing cover is arranged on the connecting hard tube and is in threaded connection with the fixed cylinder. The saline bag can be stably fixed with the sealing cover through the fixed cylinder, and when the saline bag needs to be taken down for use, the fixed cylinder is screwed out of the sealing cover, so that the saline bag is very convenient.
Furthermore, the suspended end of the connecting hard tube is provided with an inclined plane, so that the opening of the connecting hard tube is enlarged, saline in the saline bag is extruded out more easily, and the connecting hard tube punctures the heparin cap more easily to seal the venous indwelling infusion needle.
Furthermore, a film covering the inclined plane opening is arranged at the inclined plane opening. The saline bag is squeezed, and the reserved air in the saline bag is squeezed to generate pressure to force the film to open. When the saline bag is not extruded, the saline in the saline bag can not leak out even the sealing cover is separated from the saline bag, thereby meeting the sanitary standard.
The intravenous indwelling infusion needle comprises an indwelling needle sleeve, a sleeve seat, a connecting pipe and a puncture needle tube, the rear end of the indwelling needle sleeve is connected with the sleeve seat, a sealing plug is arranged in the sleeve seat, the puncture needle tube is hermetically inserted through the sealing plug and runs through the indwelling needle sleeve and the sleeve seat, and the sleeve seat is laterally provided with a connecting pipe joint which is connected with a dosing three-way joint through the connecting pipe. When two kinds of liquid medicine are infused or other medicine can enter the medicine adding three-way joint through the heparin cap, and the subsequent hard tube is conveniently connected and punctured into the heparin cap to seal the vein indwelling infusion needle.
Furthermore, the dosing port of the dosing three-way joint is connected with the heparin cap through a threaded joint.
The bottle stopper puncture outfit is provided with an exhaust pipe, and an air filter is arranged in the exhaust pipe. The exhaust pipe can exhaust the air entering the infusion hose from the infusion bottle, so that the liquid medicine flowing out of the infusion hose is always free of air, and the infusion safety is guaranteed. The air filter is used for preventing outside air from entering the transfusion hose to pollute the liquid medicine.
The utility model has the beneficial effects that:
through set up the salt solution device on the dropping funnel, take off the salt solution bag from sealed lid after convenient infusion, make and connect the hard tube and keep somewhere the transfusion needle with the vein and be connected, then extrude the salt solution bag, make the salt solution in the salt solution bag enter into the vein through connecting the hard tube and keep somewhere in the transfusion needle to its pipe sealing, the process of having left out interim outfit salt solution and syringe has improved medical staff's work efficiency.
