Description

Technical Field

[0001] The present invention relates to the technical field of anesthetics, in particular to an automatic quantitative anesthetic preparation device with adjustable concentration. Background Art

[0002] Anesthetics are drugs that induce temporary, reversible loss of sensation and pain in the body or a part of it, using either pharmaceutical or non-pharmaceutical methods. They are often used in surgery or to treat certain diseases. Anesthetics typically require preparation before use. During preparation, the dosage of different anesthetics or anesthetic adjuvants must be strictly controlled.

[0003] The existing operation method basically uses a burette to draw anesthetics through the burette, and then mix different types of anesthetics or anesthetic auxiliary agents. After mixing, the anesthetics are pipetted and injected. In this operation method, the burette cannot accurately quantify the anesthetics or anesthetic auxiliary agents after drawing them, resulting in uncontrolled modulation of the concentration of the mixed anesthetics, which can easily lead to excessive anesthesia time and even endanger the patient's health. In addition, the burette cannot easily achieve uniform mixing between the anesthetics and anesthetic auxiliary agents, which is not conducive to the full effectiveness of the anesthetics. Therefore, it is urgent to propose an automatic quantitative anesthetic preparation device with adjustable concentration to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and propose an automatic quantitative anesthetic preparation device with adjustable concentration, which can achieve the purpose of rapid anesthetic preparation and quantitative injection, improve the anesthetic preparation efficiency and rapid adjustment of anesthetic concentration, facilitate operation, save medical staff's operation time, and further improve surgical efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic quantitative anesthetic preparation device with adjustable concentration includes a quantitative liquid discharge device and a liquid storage mechanism. The quantitative liquid discharge device is used for quantitatively discharging anesthetics or anesthetic auxiliary agents, and the liquid storage mechanism is used for adding anesthetics or anesthetic auxiliary agents. The liquid collection end opening of the liquid storage mechanism is connected to the quantitative liquid discharge device, and after the anesthetics or anesthetic auxiliary agents are injected through the liquid storage mechanism, the quantitative injection is completed through the quantitative liquid discharge device.

The liquid inlet chamber is opened on the inner rear side of the U-shaped circular tube for temporarily storing anesthetics or anesthetic adjuvants. The plugging head is used to close the open end of the U-shaped circular tube. A holding soft rod is installed in the middle of the outer end of the plugging head. A piston seat is installed at the front end of the U-shaped circular tube. A liquid outlet is jointly opened in the middle of the inner side of the U-shaped circular tube and the middle of the piston seat for discharging anesthetics or anesthetic adjuvants.

[0010] Preferably, a holding ring is provided at the rear end of the outer ring surface of the outer shell, and the holding ring is a flat bucket-shaped body, and the outer shell is stably held by the holding ring.

[0016] The present invention proposes an automatic quantitative anesthetic preparation device with adjustable concentration, which has the following beneficial effects:

[0017] 1. According to the modulation standard, a fixed amount of the anesthetic or anesthetic auxiliary to be modulated is injected into the liquid inlet cavity, and then the needle is pointed downward, and the twisting ring is rotated to rotate the U-shaped tube into the interior of the outer shell, so that the anesthetic or anesthetic auxiliary inside the U-shaped tube approaches the needle, and stops after the anesthetic or anesthetic auxiliary inside the U-shaped tube is completely filled in the needle and ejected from the outer end of the needle. When the anesthetic or anesthetic auxiliary is modulated, the anesthetic or anesthetic auxiliary in the U-shaped tube collides with each other during the process of rotating the U-shaped tube into the interior of the outer shell, forming a uniform mixture, thereby saving additional shaking time and improving the modulation efficiency of the anesthetic;

The anesthetic or anesthetic auxiliary collides with each other in the U-shaped circular tube 17 to form a uniform mixture, thereby saving additional shaking time, improving the modulation efficiency of the anesthetic, and being able to obtain the discharge dose of the anesthetic. The medical staff can quickly modulate the anesthetic concentration according to the dose of the anesthetic to be injected, which is convenient for operation.

[0033] As a technical optimization solution of the present invention, a protective cover 3 is inserted and installed at the front end of the needle seat 14. The protective cover 3 is made of plastic material and is a sharp hollow cylinder. The setting of the protective cover 3 makes it easier for the needle 15 to be protected when the entire device is not in use.

[0034] Example 2

[0035] Reference Figure 1-5 An automatic quantitative anesthetic preparation device with adjustable concentration includes a quantitative liquid discharge device and a liquid storage mechanism. The quantitative liquid discharge device is used for quantitative discharge of anesthetics or anesthetic auxiliary agents, and the liquid storage mechanism is used for adding anesthetics or anesthetic auxiliary agents. The liquid collection end opening of the liquid storage mechanism is connected to the quantitative liquid discharge device, and after the anesthetics or anesthetic auxiliary agents are injected through the liquid storage mechanism, the quantitative injection is completed through the quantitative liquid discharge device.

[0036] The quantitative liquid dispensing device includes a transparent outer shell 1, a transparent tube 2, and a needle seat 14. The front end of the outer shell 1 is connected to the rear end of the transparent tube 2. The inner thread of the outer shell 1 is connected to a U-shaped circular tube 17. The front end of the transparent tube 2 is installed with the needle seat 14, and the needle 15 penetrates the needle seat 14.

[0037] A spiral ring tube 11 is provided at the outer end of the U-shaped circular tube 17 , and the U-shaped circular tube 17 is threadedly connected to the inner wall of the outer shell 1 through the spiral ring tube 11 .

[0038] As a technical optimization solution of the present invention, the front end of the needle seat 14 is provided with a protective sleeve 18, which is used to protect the exposed needle 15.

[0039] As a technical optimization solution of the present invention, the outer end of the U-shaped circular tube 17 extending to the rear side of the outer shell 1 is sleeved with a screwing ring 5, and the outside of the screwing ring 5 is provided with an anti-slip strip.
