[0017] The following is a combination of the appended examples of the present invention Figure 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0018] like Figure 1 The first embodiment is shown, which provides an ultrasonic medicine grinding device, mainly comprising:

[0019] A water bath tub 1 made of a transparent material is filled with warm water 102. The top of the water bath tub 1 is open and provided with a movable cover 4 for opening and closing the top opening of the water bath tub 1. The movable cover 4 can be separated up and down and can also be set as a flip cover.

[0020] The packaging bag 2 is a sealed structure, which contains a number of tablets 3 that need to be crushed. When in use, the packaging bag 2 is immersed in warm water 102 in the water bath 1;

[0021] The ultrasonic generator 6 is provided with an ultrasonic vibration base 5, the ultrasonic vibration base 5 is electrically connected to the ultrasonic generator 6 and is used to generate vibration, and the ultrasonic vibration base 5 is fixedly plugged into the movable cover 4, such as Figure 4 、 5As shown, when in use, the ultrasonic vibration seat 5 is in the water bath 1 and presses the packaging bag 2 against the bottom wall of the water bath 1. The bottom of the ultrasonic vibration seat 5 is set as the widest part and has a bottom plane in contact with the packaging bag 2;

[0022] Heater 7, the upper side of the heater 7 is set as the heating side, the water bath 1 can be detachably placed on the upper side of the heater 7 (that is, the water bath 1 is directly placed on the heater 7, which is very convenient), the water bath 1 can be used alone, and a temperature adjustment knob 7b and a temperature display screen 7a are provided on one side of the heater 7 (this is the conventional setting of the heater 7, and all water heaters on the market have a temperature control function). The temperature adjustment knob 7b is used to control the heating temperature of the heater 7, and the warm water 102 is appropriately heated, thereby changing the temperature of the warm water 102 in the water bath 1. The temperature display screen 7a can display the heating temperature value, and the water temperature is increased for crushing insoluble drugs with polymer coatings, and also avoids overheating of the tablets 3 caused by long-term processing.

[0023] The bottom of the water bath 1 is provided with a heat-conducting base plate 101 made of a heat-conducting material, so that the heater 7 can transfer heat to the warm water 102 in the water bath 1 to increase the temperature of the warm water 102. The temperature of the warm water 102 can be measured by a thermometer.

[0024] like Figure 2 The second embodiment is shown. Compared with the first embodiment, the second embodiment adds a movable base 8 based on the technical requirements of portable transportation, and the ultrasonic generator 6 and the heater 7 are placed in the base 8.

[0025] The base 8 is provided with a first receiving groove 8a for accommodating the ultrasonic generator 6, and a second receiving groove 8b for accommodating the heater 7. The first receiving groove 8a and the second receiving groove 8b can be made into a groove structure that is continuous from front to back, so that the ultrasonic generator 6 and the heater 7 can be placed therein for transportation and use together.

[0026] In order to facilitate the doctor to hold the transfer device, two handles 8c for hand-holding are connected to the outer side wall of the base 8.

[0027] like Figure 3 The third embodiment is shown. Compared with the first embodiment, the third embodiment eliminates the heater 7. The warm water 102 can be preheated to a specified temperature before being poured into the water bath 1. The third embodiment is a solution based on cost reduction considerations.

[0028] Taking the first embodiment as an application example, the operating principle of the medicine grinding device is described in detail.

[0029] First, we will categorize tablets by size. Currently, we do not have unified regulations for tablet sizes. Based on the data from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), and in combination with the applicant's actual tablet diameter (referring to the width or longest part of the tablet), oral tablets can be divided into the following three categories:

[0030] Small tablets: 3-5mm in diameter;

[0031] Medium-sized tablets: 5-10 mm in diameter;

[0032] Large tablets: larger than 10 mm in diameter (FDA recommends a maximum tablet diameter of no more than 22 mm).

[0033] Research has also examined the thermal stability of drugs, finding that if a drug is susceptible to decomposition or loss of efficacy at high temperatures, high-temperature treatment should be avoided. Appropriately increasing the temperature can enhance the solubility and softening of coating materials (such as polymers and sucrose), making them easier to crush. Generally speaking, a temperature between 40°C and 60°C is suitable.

[0034] The temperature range of 40-50°C is suitable for initial testing of most drugs and coating materials. Most coating materials soften within this range, making ultrasonic pulverization more suitable.

[0035] Targeting the temperature range of 50℃-60℃, it is suitable for coating materials that require higher temperatures to soften.

[0036] When using the medicine grinding device, put the tablets 3 to be ground into the packaging bag 2 (a sealed plastic bag can use the medicine washing device in the patent publication number CN219630162U of the applicant) to ensure that the packaging bag 2 is leak-free and sealed;

[0037] Add an appropriate amount of water to the water bath 1. The amount of water should be enough to immerse the packaging bag 2 so that the tablets 3 can be heated in the warm water 102.

[0038] Cover the top opening of the water bath 1 with the movable cover 4 with the ultrasonic vibrator 5, making sure that the ultrasonic vibrator 5 does not touch the bottom and side walls of the inner wall of the water bath 1, place the packaging bag 2 containing tablets 3 into the water bath 1, the ultrasonic vibrator 5 is in the water bath 1 and presses the packaging bag 2 against the inner bottom wall of the water bath 1 to shatter the tablets 3 in the packaging bag 2, adjust the output power and frequency of the ultrasonic generator 6, and select appropriate power and frequency settings according to the hardness and size of the tablets 3.

[0039] For small tablets (3-5 mm in diameter), it is recommended to use an output power of 200 watts and an output frequency of 26-30 kHz of the ultrasonic generator 6.

[0040] For medium-sized tablets (5-10 mm in diameter), it is recommended to use an output power of 300 W and an output frequency of 20-26 kHz of the ultrasonic generator 6.

[0041] For large tablets (diameter greater than 10 mm and not more than 22 mm), it is recommended to use an output power of 500 watts and an output frequency of 20 kHz of the ultrasonic generator 6.

[0042] Set the processing time of ultrasonic generator 6 according to the tablet's hardness and crushing requirements. An initial processing time of 1-3 minutes is recommended. Then, check the tablet crushing results and extend the processing time if necessary. You can also increase the water temperature in water bath 1. Initially crush the tablets at a low temperature of 40°C, then gradually increase the temperature (for example, 50°C, 60°C). After processing is complete, open the removable cover 4, remove the packaging bag 2, and inspect the tablet crushing status. If tablet 3 is not completely crushed, repeat the processing steps and extend the processing time.

[0043] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "front", "back", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention; in the present invention, it should also be noted that the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an integrally formed connection, a mechanical connection, or an indirect connection through an intermediate connecting component, and the specific meaning of the terms in this utility model can be understood based on the specific circumstances.
