Description

a syringe

technical field

The utility model belongs to the field of medical technology, in particular to a syringe.

Background technique

At present, two syringes are prepared to inject adenosine. After the injection of adenosine, the normal saline is injected. This operation is more troublesome, increases the pain of the patient, is inconvenient to the medical staff, and wastes a lot of cost. , there is a large syringe with a small syringe inside, the small syringe is filled with adenosine, the large syringe is filled with normal saline, two bolus injectors, and a one-way pressure valve can also be installed on the lowermost piston, and the uppermost bolus can be injected When the rod is pressed, the pressure at the saline increases, the valve opens, and the saline flows down and into the blood vessels.

Utility model content

In order to solve the problems raised in the above background art. The utility model provides a syringe, which has the characteristics of easy operation and cost saving.

In order to achieve the above purpose, the present invention provides the following technical solutions: a syringe, comprising a first sleeve, a surface of the first sleeve is fixedly connected with a syringe, and a second sleeve is pierced inside the first sleeve , the surface of the second sleeve is fixedly connected with a first gasket, and the surface of the first sleeve is fixedly connected with a third connection block.

Preferably, a one-way valve is embedded on the surface of the first sealing gasket, a push rod is passed through the inside of the second sleeve, and a second sealing gasket is fixedly connected to the surface of the push rod.

Preferably, a first connecting block is fixedly connected to the upper surface of the push rod, and a second connecting block is fixedly connected to the surface of the second sleeve.

Compared with the prior art, the beneficial effects of the present utility model are:

In the utility model, by arranging the first sleeve, the second sleeve and the one-way valve, when the device is used, people push the second connecting block to inject the adenosine in the first sleeve into the human body. Then people push the first connecting block, and then drive the push rod and the second sealing gasket to move, so as to inject the physiological saline in the second sleeve into the human body, the first sleeve, the second sleeve and the one-way Under the action of the valve, it is more convenient for people to inject into the patient, and the cost is saved at the same time.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example

1-2, the present invention provides the following technical solutions: a syringe, comprising a first sleeve 1, a syringe 2 is fixedly connected to the surface of the first sleeve 1, and the first sleeve 1 is pierced through the inside of the first sleeve 1. A second sleeve 3 is provided, the surface of the second sleeve 3 is fixedly connected with a first gasket 4 , and the surface of the first sleeve 1 is fixedly connected with a third connection block 10 .

Specifically, the surface of the first gasket 4 is embedded with a one-way valve 5. By setting the first sleeve 1, the second sleeve 3 and the one-way valve 5, when the device is used, people push the second sleeve Connect the block 9, and then inject the injected adenosine in the first sleeve 1 into the human body, and then people push the first connecting block 8, and then drive the push rod 6 and the second gasket 7 to move, so that the second sleeve is moved. The physiological saline in 3 is injected into the human body, under the action of the first sleeve 1, the second sleeve 3 and the one-way valve 5, it is more convenient for people to inject the patient, and the cost is saved at the same time, the second sleeve A push rod 6 is penetrated inside the barrel 3 , and a second sealing gasket 7 is fixedly connected to the surface of the push rod 6 .

Specifically, a first connecting block 8 is fixedly connected to the upper surface of the push rod 6 , and a second connecting block 9 is fixedly connected to the surface of the second sleeve 3 .

The working principle and use process of the present utility model: When using the present utility model, firstly, people connect the needle with the needle through the syringe 2, then the person injects the patient through the needle, and the person pushes the second connecting block 9 to drive the The second sleeve 3 moves and drives the first sealing gasket 4 to move at the same time. Under the action of the one-way valve 5, the mixing of adenosine and normal saline is avoided. After the injection of adenosine is completed, people push the push rod 6 to drive the The second sealing gasket 7 moves to inject the physiological saline in the second sleeve 3 into the patient's body. With the cooperation of various structures, it is more convenient for people to inject into the patient, and the cost is saved at the same time.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
