Description

A multi-needle switching device for use

technical field

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

Background technique

Intravenous infusion is a method of intravenous administration to maintain physiological balance, drug treatment or nutritional supplementation. In clinical medicine, multiple medicinal solutions may need to be added to an infusion bag during the preparation of intravenous infusion, and nurses usually use syringes to inject different medicinal solutions into the infusion bag.

However, in the process of compounding and dosing, the needle repeatedly penetrates the rubber stopper of the infusion bag, and cutting the rubber stopper may easily lead to chipping of the rubber stopper and entering the drug solution. A large amount of data shows that once the infusion rubber plug enters the human body, these particles will accumulate in specific parts, which can cause adverse consequences such as inflammatory reactions, granulomas, vascular embolism, and pyrogenic reactions. It not only increases the pressure on the nurse deployment process, but also reduces the safety of the patient's infusion.

Therefore how to design a kind of multi-needle switching device that inserts the rubber plug of the infusion bag medicine filling port without repeatedly pulling out medicine dosing is a technical problem that needs to be solved.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a multi-needle switching device, which solves the problem that the dispensing needles repeatedly penetrate the rubber stopper of the infusion bag during the dispensing process, which may easily cause the rubber stopper to fall off.

In order to achieve the above purpose, the utility model adopts the following technical solutions: it includes a cylindrical base and a needle fixed on one end surface of the base and communicated with the base; the other end surface of the base is also provided with an opening communicating with the needle, A rubber plug is provided at the port of the opening, and a small hole for the needle of the dosing needle is opened on the rubber plug; a frustum-shaped sealing plug that is movably connected with the opening is fixedly connected to the side wall of the base; The side wall of the base is also provided with a grip portion for easy pulling out of the device.

Further, the needle is a side opening type.

Further, the side walls on both sides of the base are provided with ear-shaped gripping parts.

The utility model has the following beneficial effects:

In the utility model, the needle is pierced into the dosing port, and the needle of the dosing syringe is inserted into the needle of the device to add medicine to the infusion bag. Since the needle of the device is a side-opening type, it can prevent the rubber plug from being damaged by the needle of the positive hole type. The cutting of the tip of the round opening leads to the generation of rubber stopper scraps. The use of this device can reduce the possibility of repeated insertion of the original infusion bag filling port rubber stopper, resulting in repeated cutting of the rubber stopper and the generation of rubber stopper scraps, which effectively improves the safety of infusion. sex.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Referring to FIGS. 1-4 , this solution includes a cylindrical base 1 and a needle 2 fixed on one end surface of the base 1 and communicating with the base 1 . The diameter of the base 1 is consistent with the diameter of the dosing port of the existing standard infusion bag, which prevents the base 1 from blocking the infusion port of the infusion bag and affecting the patient's infusion.

An opening 14 communicating with the needle 2 is also provided on the other end surface of the base 1 . As shown in Figure 3, after the needle of the dosing syringe is inserted into the needle 2, the dosing syringe is pushed by an external force, so that the medicine liquid in the dosing syringe enters the needle 2, and the medicine liquid entering the needle 2 flows into the infusion bag by gravity. During the dosing process, the flow rate of the liquid medicine entering the needle 2 in the dosing syringe driven by external force is slightly greater than the flow rate at which the liquid medicine flows into the infusion bag by gravity after entering the needle 2. Therefore, in order to avoid the liquid medicine overflowing during the dosing process, this embodiment A rubber stopper 11 is provided at the port of the opening 14 to prevent the liquid medicine from overflowing during the dosing process, and a small hole 111 is opened on the rubber stopper 11 for only the needle of the dosing syringe to pass through. On the one hand, it reduces the possibility of repeated puncturing of the rubber stopper 11 by the dosing syringe to produce rubber stopper debris, and on the other hand, it prevents the spillage of the medicinal solution.

A frustum-shaped sealing plug 12 movably connected to the opening 14 is fixedly connected to the side wall of the base 1 ; the sealing plug 12 matches the small hole 111 .

The sidewalls on both sides of the base 1 are also provided with grips 13 for conveniently pulling out the device, so as to prevent the nurse from contacting the mouth of the infusion bag when inserting the device, polluting the liquid medicine and being convenient for the nurse to pull out the device after the infusion is finished. There is a space between the ear-shaped gripping portion 13 and the side wall to allow fingers to pass through, which is more convenient for nurses to apply force.

The needle 2 is a side-opening type, and its tip is closed. Compared with the positive-hole needle, when the side-opening needle 2 is inserted into the rubber stopper of the infusion bag, since the tip part has no opening, the rubber stopper can be prevented from being damaged by the positive-hole type. The rounded open tip of the needle cuts in causing cork scraps.

The general use process is as follows: as shown in Figure 3-4, when using a syringe to inject and prepare various medicinal liquids in the infusion bag, first use this device to puncture the medicine filling port of the infusion bag, and then insert the medicine adding syringe into the needle 2 to add medicine to the infusion bag. medicine. After dispensing, use the sealing plug 12 on the side wall of the base 1 to block the needle 2 to avoid leakage of the liquid medicine in the infusion bag. At this time, it is not necessary to pull out the device, and directly puncture the needle of the infusion catheter into the infusion port of the infusion bag. It can be used directly; you can also choose to pull out the device and close the medicine filling port of the infusion bag for infusion.

The above is only the specific implementation of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made by using the utility model specification and accompanying drawings, or directly or indirectly used in other related technologies Fields are all included in the scope of patent protection of the utility model in the same way.
