Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

Referring to Figures 1-2, the present invention provides an intravenous infusion set for pediatric nursing and teaching, comprising an infusion hose 5 and a liquid storage bottle 2, and a drip bucket 4 is fixedly connected to the middle of the infusion hose 5. , the bottom end of the infusion hose 5 is tightly connected with the puncture needle 7, preferably the top end of the puncture needle 7 and the bottom end of the infusion hose 5 are in an interference fit, and the top end of the infusion hose 5 is connected with the lower part of the connecting needle 3. The pipe joint 301 is tightly fixed and communicated. Preferably, the bottom end of the pipe joint 301 is in an interference fit with the top of the infusion hose 5, and the connecting needle 3 is made of hard medical plastic. The outer end of the air intake pipe 302 is open. The bottom of the liquid storage bottle body 2 is vertically and fixedly connected with a connecting sleeve 202, and the connecting sleeve 202 is in close and fixed communication with the connecting needle 3. Preferably, the connecting sleeve 202 and the connecting needle 3 are in an interference fit. The top of the bottle body 2 is fixedly connected with a cover 201 for closing the top opening. The top side of the cover 201 is vertically fixed and communicated with a connecting pipe 101. Preferably, the connecting pipe 101 and the cover 201 are connected by interference fit. The top end of the connecting pipe 101 is fixedly connected with the negative pressure airbag 1 .

As a preferred solution in this case, the infusion hose 5 and the liquid storage bottle body 2 are made of transparent materials, so that the nursing staff can easily observe the liquid flow of the intravenous infusion and the liquid remaining in the liquid storage bottle body 2 during teaching. , the lower outer side of the infusion hose 5 is set with a flow rate regulator 6, so that the liquid flow rate of the infusion hose 5 can be adjusted by the flow rate regulator 6, and then the precise infusion rate can be adjusted.

The top of the puncture needle 7 and the outer end of the air inlet pipe 302 are fixed with a multi-layer filter 8. Preferably, the puncture needle 7 is made of medical grade stainless steel, so as to prevent impurities in the indicated liquid and impurities in the air from passing through the puncture needle 7. Entering into the demonstration carrier, the cover 201 and the liquid storage bottle body 2 are fixedly connected by threads, so that the cover 201 can be quickly screwed on the top of the liquid storage bottle body 2 or removed from the top of the liquid storage bottle body 2, The middle of the top surface of the cover 201 is vertically fixed with a ring-shaped hanging ring 203, which is arranged in this way to facilitate the suspension of the liquid storage bottle 2 at a high position during demonstration and teaching, thereby ensuring a smooth intravenous infusion demonstration.

The scale marks 204 are printed on the surface of the liquid storage bottle body 2, and the scale marks 204 are evenly distributed along the vertical direction. This arrangement facilitates accurate control of the addition amount when adding liquid to the liquid storage bottle body 2, so The negative pressure airbag 1 is an ellipsoid structure, and the negative pressure airbag 1 is made of rubber material, so that the negative pressure airbag 1 can inject air into the infusion hose 5 through the liquid storage bottle body 2 by reciprocating flattening and restoring. , so that the remaining liquid in the infusion tube 5 is discharged through the tail end of the puncture needle 7 .

With the above structure, when in use, unscrew the cover 201 to fill the liquid storage bottle 2 with an indication liquid, which is just medical saline.
