Description

Medical transfer device

technical field

The utility model relates to a liquid transfer device, in particular to a medical liquid transfer device.

Background technique

In the long-term clinical work in pediatrics, it is found that the amount of bottled liquid medicine is generally 50ml or 100ml. During the treatment process, most of the time children do not use the complete amount of 50ml or 100ml. At this time, the job of the medical staff is to Use a 60ml syringe to suck out the required amount, and then put it into another empty bottle for use. This method of liquid transfer requires the use of a syringe to first suck and then push out the liquid. The operation is relatively cumbersome, which not only increases the workload of medical staff, but also consumes a long time and has low work efficiency. In addition, the use of a syringe for liquid transfer, in order to avoid contamination, the syringe will be thrown away after use, which does not reflect its value for injection, resulting in a waste of resources.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a medical liquid transfer device with low cost, easy operation and fast liquid transfer speed, which can reduce the workload of medical staff, improve work efficiency, and solve the problems in the above-mentioned prior art. The problem.

The technical solution to solve the above technical problems is: a medical liquid transfer device, including a hollow liquid transfer device body, a control rod and a sealing head. The liquid transfer device body consists of an upper tapered plug, a jacket, The inner sleeve, the middle liquid storage section and the lower conical plug, the upper conical plug has a liquid inlet, the lower conical plug has a liquid outlet, the upper conical plug is connected with the jacket, and the inner wall of the jacket The lower sealing ring is connected, and the outer wall of the inner sleeve is connected with the upper sealing ring located above the lower sealing ring. Connection, the middle liquid storage section is connected with the lower conical plug, the control rod is connected with the sealing head and located in the body of the liquid transfer device, the control rod is connected to the top inner wall of the outer sleeve through the connecting rod, when the bottom of the outer sleeve is located at the lower part of the inner sleeve When the sealing head is in contact with the inner wall of the lower tapered plug to seal the liquid outlet, when the bottom end of the outer sleeve is located at the upper part of the inner sleeve, there is a gap for liquid to pass between the sealing head and the inner wall of the lower tapered plug.

There are 2 to 6 liquid inlets and liquid outlets respectively.

The sealing head is hollow or solid conical. When the bottom end of the outer sleeve is located at the lower part of the inner sleeve, the outer edge of the sealing head closely fits the inner wall of the bottom end of the lower conical plug to seal the liquid outlet.

Due to the adoption of the above structure, the utility model has the following beneficial effects:

1. When using the utility model to transfer liquid, insert the upper conical plug into the bottled liquid medicine, insert the lower conical plug into another empty bottle, and then push the jacket upwards, and the liquid can be transferred from the bottled liquid medicine to another empty bottle. Compared with the existing liquid transfer method, the liquid transfer speed is fast and the operation is easy, thereby reducing working time, greatly improving work efficiency, and reducing the workload of medical staff.

2. The utility model is a device specially used for the transfer of medicinal liquid. Using the utility model for the transfer of medicinal liquid embodies the value of making the best use of everything. Moreover, the utility model has simple structure and lower cost of mass production, and is suitable for promotion and use in hospitals and other places where medicinal liquids are frequently transferred.

Below, the technical features of the medical liquid transfer device of the present utility model will be further described in conjunction with the accompanying drawings and embodiments.

Detailed ways

Embodiment 1: A medical liquid transfer device, as shown in Figures 1-5, includes a hollow liquid transfer device body 1, a control rod 5 and a sealing head 6, and the liquid transfer device body 1 is sequentially arranged from top to bottom It is an upper tapered plug 11, an outer jacket 12, an inner sleeve 13, a middle liquid storage section 14 and a lower tapered plug 15, and the upper tapered plug 11 and the lower tapered plug 15 can be inserted into the rubber stopper of a liquid medicine bottle. The upper conical plug 11 is provided with a liquid inlet 111, and the lower conical plug 15 is provided with a liquid outlet 151. The upper conical plug 11 is connected with the outer cover 12, and the inner wall of the outer cover is connected with a lower sealing ring 4, and the inner cover The outer wall is connected with an upper sealing ring 3 located above the lower sealing ring. The outer sleeve is set on the inner sleeve. The upper sealing ring and the lower sealing ring are located between the inner sleeve and the outer sleeve. The effect of the gap between the inner sleeves, on the other hand, plays the role of a limit, which can prevent the outer sleeve from breaking away from the inner sleeve when it moves upwards. The inner sleeve 13 is connected to the middle liquid storage section 14, and the middle liquid storage section is connected to the lower conical plug 15. The control rod 5 is connected to the sealing head 6 and is located in the body of the liquid transfer device. The control rod 5 is connected through the connecting rod 2 On the top inner wall of the outer cover, the connecting rod 2 does not pass through the inner cover. When the bottom of the jacket is at the bottom of the inner jacket, the sealing head 6 contacts the inner wall of the lower tapered plug to seal the liquid outlet; when the bottom of the jacket is at the upper part of the inner jacket, there is space between the sealing head and the inner wall of the lower tapered plug for liquid to pass through. gap.

In this embodiment, from a cross-sectional view, the cross-sectional shape of the middle liquid storage section 14 is similar to a rhombus. As an alternative, the middle liquid storage section 14 can also have other structural shapes, as long as its internal capacity is large enough to store a certain amount of liquid.

In this embodiment, there are two liquid inlets and two liquid outlets respectively. As a conversion, the number of liquid inlets and liquid outlets can be determined according to actual needs, which can be one, three or four. or more.

In the utility model, the sealing head 6 is hollow or solid conical. When the bottom of the outer sleeve is located at the lower part of the inner sleeve, the outer edge of the sealing head 6 closely fits the inner wall of the bottom end of the lower conical plug to seal the liquid outlet. As a change, the sealing head 6 can also adopt other shapes, as long as it can conveniently seal and open the liquid outlet.

The utility model is a disposable product, which can meet the aseptic requirements. When leaving the factory, the bottom of the outer sleeve is located at the lower part of the inner sleeve, and the sealing head 6 is in contact with the inner wall of the lower tapered plug to seal the liquid outlet, and the liquid cannot flow out from the liquid outlet (as shown in Figure 3 shown).

Use process: Insert the upper tapered plug 11 into the bottle containing the liquid medicine, the lower tapered plug 15 into another empty bottle, the bottle containing the liquid medicine is located above the empty bottle, then move the jacket 12 upwards, and pass the control rod 5 Drive the sealing head 6 to move upwards, open the liquid outlet (as shown in Figure 4), the liquid flows from the bottle containing the liquid medicine into the empty bottle, and the medicine transferred in is measured through the scale on the empty bottle, when the medicine in the original empty bottle When the liquid volume reaches the required amount, the overcoat 12 is moved downward so that the sealing head 6 seals the liquid outlet, and then the upper tapered plug 11 and the lower tapered plug 15 are pulled out to complete the liquid transfer process.
