Description

Chemical Liquid Supply Control Device}

The present invention relates to a device for controlling the supply amount of a chemical solution, and more specifically, to a device that integrates a configuration for controlling the supply amount of the chemical solution and a configuration for injecting additional chemical solution, thereby reducing the manufacturing cost, blocking mutual backflow, and controlling the initial stage by operation. It relates to a chemical supply volume control device that improves supply efficiency by increasing the chemical injection amount, improves stability by allowing the supply and injection amounts of the chemical solution to be adjusted with simple operations, and improves supply efficiency by effectively supplying the chemical solution in a fixed amount. .

Generally, patients have a reduced ability to ingest and digest food through the stomach, so necessary nutrients such as glucose are injected into the patient's blood vessels. In addition, various medicinal solutions such as anticancer drugs, antibiotics, and painkillers for the treatment of diseases are also injected into the patient's blood vessels. At this time, it is important to consistently inject the exact amount of nutrients or medicine injected into the patient's blood vessels according to the patient's condition.

For this purpose, a device for controlling the supply amount of fine chemicals, such as an infusion pump, has been developed and used, but it is expensive, is a rechargeable electric device, has the potential to malfunction, and is difficult to move due to its volume and weight. There are many difficult problems.

Recently, devices that physically control the amount of chemical solution supplied by user manipulation have been developed and used instead of infusion pumps.

Accordingly, Registered Patent Publication No. 10-0468222 discloses a technology that can replace the infusion pump with low-cost consumables, but this is a method of controlling the amount of chemical solution by gradually changing the length, width, or depth of the flow path through which the chemical solution flows. Subsequently, it is difficult to know the exact change in chemical volume due to changes in the flow path. Even if the scale is displayed using data acquired through experimentation, the accuracy is low.

In addition, a typical additional drug supply device, such as a painkiller, which supplies additional drug solution directly operated by the patient when the patient suddenly feels pain, is used by being connected to the drug supply volume control device.

The additional chemical solution supply device of the prior art is provided in the form of a tube where the chemical solution is temporarily stored and then injected by the patient's push operation. Since the added chemical solution is limited to the capacity of the tube, it is necessary to increase or decrease the additional amount. There was a problem that the tube had to be replaced.

In addition, the additional chemical solution supply device of the prior art had a problem in that it was difficult to control the additional amount of chemical solution added by the pressing operation as the stored amount had to be adjusted to the speed and time at which the chemical solution was supplied, and the additional amount changed when time was delayed.

As described above, since a device for controlling the supply amount of the chemical solution and a device for injecting additional chemical solution are installed, each device must be visited and adjusted as needed during operation, which causes inconvenience in use.

In addition, when a device for controlling the supply of chemical solution and a device for injecting additional chemical solution are installed, a lot of time is required to store the chemical solution added when first connected and to remove the internal air by performing an operation to control the chemical solution speed. There was this.

The present invention was devised to solve the above-mentioned problems. The purpose of the present invention is to reduce manufacturing costs and block backflow by integrating a configuration for controlling the supply amount of the chemical solution and a configuration for additionally injecting the chemical solution. Supply efficiency is improved by increasing the initial chemical injection amount by operation, and the supply amount of multiple stages can be adjusted by selectively combining different chemical liquid amounts by the user's rotation operation. Additional chemical injection amount can also be adjusted to match the supply amount and addition. The purpose of the present invention is to provide a chemical solution supply volume control device that improves the efficiency of controlling the injection amount and improves supply efficiency by effectively supplying the chemical solution in a fixed amount.
