Abstract
The utility model discloses a heatable syringe, include: the liquid storage container is provided with a first liquid outlet, a second liquid outlet and a liquid inlet; the first liquid pump is communicated with a first liquid outlet and a liquid inlet of the liquid storage container through pipelines to form a circulation loop; the heating device is arranged on a pipeline between the first liquid pump and the liquid storage container; one end of the second liquid pump is communicated with a second liquid outlet of the liquid storage container through a pipeline; and the temperature sensor is arranged in the liquid storage container. Liquid passes through circulation heating in the stock solution container, and the temperature is more even in the liquid, and the temperature value that temperature sensor measured and obtained is more accurate, and then has guaranteed the accuracy of liquid output temperature. The second liquid pump is used as liquid injection power, and the two powers are independently arranged. When the temperature of the liquid does not reach the standard, the second liquid pump can be independently controlled to stop working, so that the injector is controlled to stop injection when uniform heating is realized, and the injection device is flexible and convenient.
Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a heatable injector.
Background
In order to heat the liquid injected into the human body, a heating device is generally provided in the injector. However, the existing heating device has the following disadvantages: the even heating of liquid can not be realized, and the temperature information that temperature sensor gathered can not comprehensive accurate reflection inject to the temperature of human body, and then accomplish the temperature of accurate control injection to the liquid in the human body hardly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a heatable syringe to solve the problem that proposes among the above-mentioned background art.
The technical scheme adopted for solving the technical problems is as follows: a heatable syringe comprising:
the liquid storage container is provided with a first liquid outlet, a second liquid outlet and a liquid inlet;
the first liquid pump is communicated with a first liquid outlet and a liquid inlet of the liquid storage container through pipelines to form a circulation loop;
the heating device is arranged on a pipeline between the first liquid pump and the liquid storage container;
one end of the second liquid pump is communicated with a second liquid outlet of the liquid storage container through a pipeline; and
and the temperature sensor is arranged in the liquid storage container.
As an improvement of the scheme, the heating device is arranged on a pipeline between the first liquid pump and the liquid inlet of the liquid storage container.
As an improvement of the scheme, the other end of the second liquid pump is communicated with a syringe needle.
As an improvement of the scheme, the pipeline is a silicone tube.
As a modification of the above scheme, the second liquid pump is a peristaltic pump.
Has the advantages that: the utility model discloses in, be provided with two drawing liquid pumps, wherein first drawing liquid pump, heating device and liquid storage container constitute a circulation circuit jointly, and liquid passes through circulation heating in the liquid storage container, and the temperature is more even in the liquid, and the temperature value that temperature sensor measured and obtained is more accurate, and then has guaranteed liquid output temperature's accuracy. Meanwhile, the second liquid pump is used as liquid injection power, and the two powers are independently arranged. When the temperature of the liquid does not reach the standard, the second liquid pump can be independently controlled to stop working, so that the injector is controlled to stop injection when uniform heating is realized, and the injection device is flexible and convenient.
Drawings
The invention is further described with reference to the following figures and examples:
fig. 1 is a schematic view illustrating an operation principle of a heatable syringe according to an embodiment of the present invention.
Detailed Description
Referring to fig. 1, a heatable syringe according to an embodiment of the present invention mainly includes a liquid storage container 2, a first liquid pump 4, a second liquid pump 5, a heating device 3, and a syringe needle (not shown in the figure). Wherein, the liquid storage container 2 is provided with a first liquid outlet, a second liquid outlet and a liquid inlet. The first liquid pump 4 is communicated with the first liquid outlet and the liquid inlet of the liquid storage container 2 through pipelines to form a circulation loop. The heating device 3 is arranged on a pipeline between the first liquid pump 4 and the liquid inlet of the liquid storage container 2 to realize the heating of the liquid. One end of the second liquid pump 5 is communicated with a second liquid outlet of the liquid storage container 2 through a pipeline, so that liquid in the liquid storage container 2 is pumped out; the other end is communicated to the syringe needle through a pipeline, and the liquid is injected into the human body through the syringe needle. The temperature sensor 1 is installed inside the liquid storage container 2 to collect the temperature of the liquid.
Wherein, the heating device 3 can also be arranged on a pipeline between the first liquid pump 4 and the first liquid outlet of the liquid storage container 2, and is also used for heating liquid in a circulating loop.
In comparison, the heating device 3 is disposed on the pipeline between the first liquid pump 4 and the liquid inlet of the liquid storage container 2, and the heated liquid can flow through the temperature sensor 1 more quickly, so that the temperature sensor 1 can obtain real-time accurate temperature information.
Through setting up two drawing liquid pumps, wherein first drawing liquid pump 4, heating device 3 and liquid storage container 2 constitute a circulation circuit jointly, and liquid passes through circulation heating in the liquid storage container 2, and the temperature is more even in the liquid, and the temperature value that temperature sensor 1 measured and obtained is more accurate, and then has guaranteed liquid output temperature's accuracy. Meanwhile, the second liquid pump 5 is used as a liquid injection power, and the two powers are independently arranged. When the temperature of the liquid does not reach the standard, the second liquid pump 5 can be independently controlled to stop working, so that the injector is controlled to stop injection when uniform heating is realized, and the injection device is flexible and convenient.
In the above embodiment, the tube is a silicone tube, the second liquid pump 5 is a peristaltic pump, and the heating device 3 may be a heating wire.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
