Description

Multi-needle switching device

Technical Field

The utility model relates to the field of medical equipment, in particular to a multi-needle switching device.

Background

Intravenous infusion is a method of maintaining physiological balance, treating drug or supplementing nutrition by intravenous administration. In clinical medicine, multiple kinds of liquid medicine may need to be added into one infusion bag in the process of preparing intravenous infusion, and a nurse usually uses a syringe to inject different liquid medicines into the infusion bag.

However, in the process of blending and adding medicine, the needle head is repeatedly inserted into the rubber plug of the infusion bag, and the situation that the rubber plug is easy to fall off and enter into medicine liquid is caused by cutting the rubber plug. A large amount of data show that once the infusion rubber plug enters a human body, the particles can be stacked and accumulated at specific positions, and adverse effects such as inflammatory reaction, granuloma, vascular embolism, pyrogenic reaction and the like can be caused. Not only increases the pressure for the nurse's blending process, but also reduces the safety of the patient transfusion.

Therefore, how to design a multi-needle switching device which is inserted into a rubber plug of a medicine adding port of an infusion bag and does not need to be repeatedly pulled out for adding medicine is a technical problem to be solved.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide a multi-needle switching device, which solves the problem that in clinic, a medicine dispensing needle repeatedly penetrates through a rubber plug of an infusion bag in the medicine dispensing process to easily cause the rubber plug to drop scraps.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: comprises a cylindrical base and a needle head which is fixedly arranged on one end face of the base and communicated with the base; an opening communicated with the needle head is further formed in the other end face of the base, a rubber plug is arranged at the port of the opening, and a small hole for the needle head of the dosing needle to pass through is formed in the rubber plug; a sealing plug which is movably connected with the opening and is in a frustum shape is fixedly connected to the side wall of the base; the side wall of the base is also provided with a holding part which is convenient for pulling out the device.

Further, the needle is of a side opening type.

Further, the side walls on two sides of the base are provided with lug-shaped holding parts.

The utility model has the following beneficial effects:

according to the utility model, the needle head is penetrated into the medicine adding port, and the medicine adding injector needle head is inserted into the needle head of the device to add medicine to the infusion bag, and as the needle head of the device is of a side opening type, the generation of rubber plug scraps caused by cutting into the round opening tip of the normal opening type needle head can be avoided, the possibility of the rubber plug being repeatedly inserted into the medicine adding port of the original infusion bag to generate the rubber plug scraps can be reduced, and the safety of infusion is effectively improved.

Detailed Description

The utility model is described in further detail below with reference to the attached drawings and specific examples:

referring to fig. 1-4, the scheme comprises a cylindrical base 1 and a needle 2 fixedly arranged on one end face of the base 1 and communicated with the base 1. The diameter of the base 1 is consistent with that of a medicine feeding port of an existing standard infusion bag, so that the base 1 is prevented from shielding the infusion port of the infusion bag, and infusion of a patient is prevented from being influenced.

The other end face of the base 1 is also provided with an opening 14 communicated with the needle head 2. As shown in fig. 3, after the needle of the dosing syringe is inserted into the needle 2, the dosing syringe is pushed by external force, so that the liquid medicine in the dosing syringe enters the needle 2, and the liquid medicine entering the needle 2 flows into the infusion bag by gravity. In the process of adding medicine, the flow rate of the liquid medicine in the medicine adding injector entering the needle head 2 is slightly larger than the flow rate of the liquid medicine entering the needle head 2 and flowing into the infusion bag by gravity, so in order to avoid the overflow of the liquid medicine in the medicine adding process, the rubber plug 11 for preventing the overflow of the liquid medicine in the medicine adding process is arranged at the port of the opening 14, and the rubber plug 11 is provided with a small hole 111 only for the needle head of the medicine adding injector to pass through. On one hand, the possibility that the rubber plug 11 is repeatedly punctured by the medicine adding injector to generate rubber plug scraps is reduced, and on the other hand, the medicine liquid is prevented from overflowing.

A sealing plug 12 which is movably connected with the opening 14 and is in a frustum shape is fixedly connected on the side wall of the base 1; the sealing plug 12 mates with the aperture 111.

The side walls on two sides of the base 1 are also provided with the holding parts 13 which are convenient for pulling out the device, so that the hands of nurses are prevented from contacting with the infusion bag mouth when the nurses insert the device, the liquid medicine is polluted, and the nurses are convenient for pulling out the device after the infusion is finished. A space which can allow the finger to pass through is arranged between the ear-shaped holding part 13 and the side wall, thereby being more convenient for a nurse to apply force.

The needle head 2 is a side open hole type needle head, the tip end of the needle head is closed, compared with a positive hole type needle head, when the side open hole type needle head 2 is inserted into a rubber plug port of an infusion bag, the tip end part of the needle head is not provided with an opening, so that the rubber plug can be prevented from being cut into the rubber plug by the circular opening tip end of the positive hole type needle head to cause generation of rubber plug scraps.

The general application process is as follows: as shown in fig. 3-4, when the injector is used for injecting and preparing various liquid medicines into the infusion bag, the device is firstly used for penetrating into a medicine adding port of the infusion bag, and then the medicine adding injector is inserted into the needle head 2 to add medicine into the infusion bag. After the medicine dispensing is finished, the needle head 2 is blocked by using the sealing plug 12 on the side wall of the base 1, so that the liquid medicine in the infusion bag is prevented from leaking, the device does not need to be pulled out at the moment, and the needle head of the infusion catheter is directly penetrated into the infusion port of the infusion bag for direct use; alternatively, the infusion can be performed after the device is pulled out and the medicine feeding port of the infusion bag is closed.

The foregoing description is only specific embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the present utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present utility model.
