Description

Technical Field

[0001] The utility model relates to the technical field of proportioning, in particular to a quantitative proportioning device for anesthetic agents. Background Art

[0002] Now, when preparing anesthetic drugs, multiple raw materials need to be mixed according to strict ratios, so as to produce anesthetic drugs that can ensure that patients receive proper anesthesia during surgery without complications due to overdose or underdose of drugs.

[0003] Patent No. CN220443615U in the prior art is a device for quantitatively proportioning anesthetic drugs. Anesthetic drug ingredients can be pre-stored through multiple storage bottles. A feed valve is installed at the bottom of the storage bottle, and the feed valve is connected to the inside of the proportioning tank through a feed pipe. Therefore, the anesthetic proportioning raw materials stored in the storage bottle can be injected into the proportioning tank by controlling the opening and closing state of the feed valve. A scale groove is installed on the outside of the storage bottle. When the drug in the storage bottle is continuously injected into the proportioning tank, the specific content of the anesthetic drug added to the proportioning tank can be clearly seen through the scale groove. When the amount of anesthetic ingredients injected into the proportioning tank reaches a suitable value, the injection of the anesthetic ingredients can be stopped by closing the feed valve, thereby ensuring the quantitative amount of each raw material in the anesthetic drug.

[0004] However, when using this quantitative proportioning device, it is necessary to observe the drug liquid content inside the storage bottle in real time through the scale groove located on the outer surface of the storage bottle. When the specified content is reached, the feed valve is closed, but it takes a certain amount of time to close the feed valve. In the process of closing the feed valve, some drug liquid will pass through the feed valve into the interior of the proportioning tank. This situation will cause an error in the drug liquid ratio, and it is easy to make observation errors by visual observation. If there is less, the feed valve needs to be opened again. If there is more, the equipment needs to be opened to take out the excess raw materials. The accuracy of this quantitative proportioning device is low; therefore, it does not meet the existing needs. In this regard, we propose an anesthetic quantitative proportioning device. Utility Model Content

However, it takes a certain amount of time to close the feed valve. During the process of closing the feed valve, some drug liquid will enter the interior of the proportioning tank through the feed valve. This situation will cause an error in the drug liquid ratio, and it is easy to make mistakes in observation by eyes. If there is less, the feed valve needs to be opened again.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The transparent pre-container tube 2 (model: PMMA), the external thread sealing rod 18 (model: M16) and the stepping motor 11 (model: HB860) mentioned in the utility model can be purchased from the market or obtained through private customization.

[0026] See also Figures 1 to 4 The utility model provides an embodiment: an anesthetic agent quantitative proportioning device, comprising a proportioning tank 1, a plurality of circular plates A4 are arranged above the proportioning tank 1, a raw material storage barrel 8 is fixedly mounted on the upper end surface of the circular plate A4, and the raw material storage barrel 8 contains liquid medicine raw materials;

[0027] A transparent pre-receiving tube 2 is provided below the circular plate A4 and is fixedly mounted on the upper end surface of the proportioning tank 1. A graduated groove 3 is provided on the outer surface of the transparent pre-receiving tube 2.

[0028] The upper side of the transparent pre-containment tube 2 is provided with a capacity adjustment sleeve 6 that fits with its inner wall, and both sides above the capacity adjustment sleeve 6 are provided with a single-bar cylinder 7 that is fixedly mounted on the upper end surface of the circular plate A4, and the piston rod of the single-bar cylinder 7 is fixed to the capacity adjustment sleeve 6;

[0029] An internal thread sealing port 14 penetrating the capacity adjustment sleeve 6 is provided at the middle position of the lower end surface of the capacity adjustment sleeve 6, and an external thread sealing rod 18 matching its internal thread is provided inside the internal thread sealing port 14, and a lifting sealing mechanism is connected to the upper end surface of the external thread sealing rod 18, through which the lifting sealing mechanism can drive the external thread sealing rod 18 to rotate and simultaneously drive it to move up and down.

[0030] The lifting and sealing mechanism includes a cylindrical metal shell 10, and a fixing rod 13 is fixedly provided on the front and rear end faces of the cylindrical metal shell 10, and the other end of the fixing rod 13 is fixed to the inner wall of the capacity adjustment sleeve 6; a stepper motor 11 is fixedly installed on the upper side of the inner wall of the cylindrical metal shell 10, and the output shaft of the stepper motor 11 is connected to a square rotating shaft 12 through a coupling; when it is necessary to inject 200 grams of liquid medicine raw materials located in the raw material storage barrel 8 into the interior of the proportioning tank 1, the stepper motor 11 is started first, and the stepper motor 11 can drive the square rotating shaft 12 connected thereto to rotate.

[0031] A cylindrical groove 15 is provided below the stepper motor 11 and is located inside the cylindrical metal housing 10. An internal threaded through hole 17 is provided in the middle of the inner wall at the lower end of the cylindrical groove 15. The top end of the external threaded sealing rod 18 is located inside the internal threaded through hole 17, and the external thread of the external threaded sealing rod 18 matches the internal thread of the internal threaded through hole 17. A circular plate B16 is fixedly connected to the upper end surface of the external threaded sealing rod 18, and the lower end surface of the circular plate B16 fits the inner wall of the cylindrical groove 15.

[0032] The upper end surface of the circular plate B16 is provided with a square slot 19 which passes through the circular plate B16 and extends to the inside of the external thread sealing rod 18, and the square shaft 12 is inserted into the inside of the square slot 19. The cross-sectional shape of the inner wall of the square slot 19 is a square. The outer surface of the square shaft 12 fits with the inner wall of the square slot 19, and the square shaft 12 and the square slot 19 are slidably connected. Since the outer surface of the square shaft 12 fits with the inner wall of the square slot 19 located on the upper end surface of the circular plate B16 and the inside of the external thread sealing rod 18, when the square shaft 12 rotates, it will synchronously drive the circular plate B16 and the external thread sealing rod 18. The threaded sealing rod 18 rotates. When the external threaded sealing rod 18 rotates, the internal thread of the internal threaded through hole 17 is transmitted, so that the rotating external threaded sealing rod 18 can move up and down while rotating. At this time, the external threaded sealing rod 18 is moved upward until the external threaded sealing rod 18 completely leaves the inside of the internal threaded sealing port 14. When the external threaded sealing rod 18 completely leaves the inside of the internal threaded sealing port 14, the single-bar cylinder 7 is started, and the capacity adjustment sleeve 6 can be pushed downward as a whole through the single-bar cylinder 7. At this time, the lower end surface of the capacity adjustment sleeve 6 is moved to the 200-gram mark on the scale groove 3 on the outer surface of the transparent pre-containment tube 2;

[0033] The reason why the internal thread sealing port 14 is opened first before moving the capacity adjustment sleeve 6 is that when the external thread sealing rod 18 is inside the capacity adjustment sleeve 6, the inside of the transparent pre-containment tube 2 is in a sealed state. If the capacity adjustment sleeve 6 is pushed downward while the transparent pre-containment tube 2 is sealed, the transparent pre-containment tube 2 may be cracked due to the pressure.

[0034] The lower end surface of the transparent pre-containment tube 2 is fixedly installed with an electric valve tube 9 located inside the proportioning tank 1, and the interior of the transparent pre-containment tube 2 is communicated with the interior of the electric valve tube 9; when the height adjustment of the capacity adjustment sleeve 6 is completed, the raw material storage barrel 8 is opened, and under the action of gravity, the liquid medicine raw material located inside the raw material storage barrel 8 will enter the interior of the capacity adjustment sleeve 6, and enter the interior of the transparent pre-containment tube 2 through the internal thread sealing port 14 located on the lower end surface of the capacity adjustment sleeve 6. When the horizontal line of the liquid medicine raw material is higher than the internal thread sealing port 14, the stepper motor 11 is started again to drive the external thread sealing port 14 to rotate. The external threaded sealing rod 18 rotates and moves downward, and the external threaded sealing rod 18 rotating and moving downward will eventually enter the interior of the internal threaded sealing port 14, thereby sealing the internal threaded sealing port 14. When the internal threaded sealing port 14 is sealed, the liquid medicine raw material below the capacity adjustment sleeve 6 will be divided, and at this time, the content of the liquid medicine raw material below the capacity adjustment sleeve 6 is exactly 200 grams. After that, the electric valve tube 9 can be opened to inject 200 grams of liquid medicine raw material into the proportioning tank 1. Through the above technical solution, the quantitative amount of each liquid medicine raw material can be ensured, thereby ensuring the quality of the anesthetic agent.

[0035] An L-shaped support rod 5 is fixedly provided in the middle position of the front and rear end surfaces of the circular plate A4, and the other end of the L-shaped support rod 5 is fixed to the upper end surface of the proportioning tank 1; the circular plate A4 can be supported by the L-shaped support rod 5 to reinforce it.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
