Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an infusion catheter for medical treatment, including pjncture needle 1, pipe 3 and syringe needle 13, the one end intercommunication of pjncture needle 1 has first connecting pipe 2, and communicate between first connecting pipe 2 and the pipe 3, and the one end intercommunication of pipe 3 has drip chamber 4, communicate between drip chamber 4 and the syringe needle 13, fixedly connected with first sleeve 5 on the first connecting pipe 2, and sliding connection has second sleeve 6, and first sleeve 5 is close to the port position department of pjncture needle 1, be close to that pjncture needle 1 can be better carry out the position restriction to pjncture needle 1, increase stability, divide equally on first sleeve 5 and the second sleeve 6 and do not fixedly connected with a first sticky tape 7 and a second sticky tape 8.
Specifically, as shown in fig. 1 and 2, first sticky tape 7 fixed connection is in the intermediate position department of first sleeve 5 and second sleeve 6, second sticky tape 8 and the both ends fixed connection of first sleeve 5 and second sleeve 6, and first sleeve 5 and second sleeve 6 are the stereoplasm material and make, prevent that the sticky tape from causing the influence to the passageway of first connecting pipe 2, first sticky tape 7 and second sticky tape 8 are located the horizontal both sides of first connecting pipe 2 respectively, form the power to both sides, be convenient for more fixed, and the one side of first sticky tape 7 and second sticky tape 8 all glues and has barrier paper 11, barrier paper 11 directly glues with the sticky face of sticky tape.
Specifically, as shown in fig. 1 and 3, the bottom fixedly connected with of dropping funnel 4 contacts piece 9, and the inside of dropping funnel 4 is provided with floating block 10, floating block 10 adopts the rubber material, and its bottom central point department of putting is provided with the balancing weight, and the top diameter of floating block 10 is greater than two-thirds of dropping funnel 4 internal diameter, prevent that floating block 10 from at the inside upset of dropping funnel 4, ensure simultaneously can not causing the influence to the circulation of liquid medicine, the bottom of floating block 10 is the circular cone structure, the bell jar has been seted up to the inboard of contacting block 9, communicate between the bottom of bell jar and the pipe 3, and transition fit between bell jar and the 10 bottom of floating block, remaining liquid medicine can increase mutual adsorptivity, leakproofness when guaranteeing the contact, the intercommunication has second connecting pipe 12 between dropping funnel 4 and the syringe needle 13, and second connecting pipe 12 is the stereoplasm material.
The working principle is as follows: when the puncture needle is used, after a nurse pierces the puncture needle 1 into a patient, the separation paper 11 on the first adhesive tape 7 and the second adhesive tape 8 on the first sleeve 5 at the tail part of the puncture needle 1 is removed, the puncture needle 1 is fixed by pulling the two adhesive tapes in different directions, then the position of the second sleeve 6 on the first connecting pipe 2 is moved, the state of the first connecting pipe 2 is adjusted, the influence of the first connecting pipe 2 on the puncture needle 1 is reduced, and then the position of the second sleeve 6 is fixed through the first adhesive tape 7 and the second adhesive tape 8, so that the stability during infusion is improved, and the convenience in use of the infusion catheter is improved; when the infusion is finished, the liquid level of the dropping funnel 4 descends, so that the floating block 10 floating in the dropping funnel moves downwards, and under the condition that the liquid medicine in the dropping funnel 4 is completely absent, the floating block 10 can be attached to the inner side of the contact block 9, so that the air circulation in the dropping funnel 4 is blocked, the internal pressure of the dropping funnel is not changed easily, the liquid medicine in the lower catheter 3 stops flowing, and the possibility of air flowing into a human body under the condition that the liquid medicine is suspended is effectively reduced.
