Description

Technical Field

[0001] This utility model relates to the field of electronic drug delivery technology, specifically to an electronic drug delivery device with replaceable connectors for children. Background Technology

[0002] Most oral liquids and granules of traditional Chinese medicine have a relatively bitter taste to ensure efficacy and sufficient dosage of active ingredients, making them difficult to swallow. Children, in particular, are more sensitive to the taste of medicine but cannot overcome this urge like adults. They often cannot cooperate well and take the medicine quietly. Some children often experience vomiting or choking after being forced to take the medicine due to overreaction of their taste system and intestines. They cannot take the medicine on time and in the correct dosage, which hinders their treatment and leaves many parents helpless. In particular, many oral liquids and decoctions of traditional Chinese medicine have long treatment cycles and particularly unbearable tastes, making it even more difficult for patients to tolerate and take the medicine regularly and in the correct dosage. This is especially true for children. To solve this problem, some parents use electronic medicine dispensers to administer medicine to their children.

[0003] However, existing electronic drug delivery devices still have certain drawbacks in use. For example, the oral delivery connectors of existing drug delivery devices come in various styles, such as syringe, breast-nose, spoon, and dropper. The interface sizes of these connectors are different, and specific oral delivery connectors can only be installed on the main interface of a specific drug delivery device. It is not possible to select different styles of connectors according to the user's needs. In addition, the accompanying parents are often elderly people, and the dosage is often too high or too low, which may not achieve the desired effect. This also easily leads to potential safety hazards in oral medication. Utility Model Content

Furthermore, the inclusion of a voice component provides the user with a clear and intuitive signal indicating that the required dosage has been reached. The following provides a detailed description of this electronic drug delivery device with replaceable connectors for children. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figure 1-7This embodiment provides an electronic drug delivery device with replaceable connectors for children, comprising: a drug delivery device housing 1, a threaded cavity 104 at the bottom of the housing 1, a mounting box 5 on one side of the housing 1, an oral delivery connector 102 mounted below the housing 1, a device cavity 101 inside the housing 1, and a movable cavity 103 inside the housing 1; a replacement component located at the bottom of the housing 1 for easy replacement of the oral delivery connector 102, the replacement component including: an annular connecting block 3, an annular block a 301, an annular block b 302, an annular block c 303, and an elastic rubber ring 304; and a voice component located on one side of the housing 1 and the mounting box 5 for reminding the user that the required dosage of the medication has been reached, the voice component including: a recording module 502, a microcontroller 503, a speaker 504, an L-shaped connecting tube 402, a threaded rod 602, and a rectangular frame 6.

[0027] An electric push rod 2 is fixedly installed inside the device cavity 101. The bottom end of the electric push rod 2 extends into the moving cavity 103 and is fixedly connected to a piston 201. A drug delivery device main connector 105 is fixedly connected to the bottom of the inner wall of the moving cavity 103. An internal thread is formed inside the threaded cavity 104. An annular connecting block 3 is provided inside the threaded cavity 104. An external thread is provided on the outside of the annular connecting block 3, which mates with the internal thread inside the threaded cavity 104. The annular connecting block 3 is threadedly connected to the threaded cavity 104. The drug delivery device housing 1 and The oral administration connector 102 is provided with graduations on its outer side; the bottom of the annular connecting block 3 is fixedly connected to an annular block a301, the bottom of the annular block a301 is fixedly connected to an annular block b302, the annular block b302 is fixedly connected to an annular block c303, and the outer sides of the annular block a301, the annular block b302 and the annular block c303 are all fitted with elastic rubber rings 304, and the bottom end of the main tube 105 of the administration device protrudes from the bottom end of the annular block c303, and the oral administration connector 102 is movably installed on the outer side of the annular block c303.

[0028] In use, different specifications and styles of oral drug delivery connectors 102 can be selected according to needs. The annular block c303 is rotated, causing the annular block b302, annular block a301, and annular connecting block 3 to rotate inside the threaded cavity 104. This causes the annular connecting block 3 to move downwards, thereby causing the annular block b302 or annular block a301 to move downwards. Then, the bottom end of the main connector 105 of the drug delivery device is inserted into the oral drug delivery connector 102, and the oral drug delivery connector 102 is fitted onto the annular block c303 or annular block b302, or the bottom outer side of the annular block a301. Due to the elastic rubber... Both the rubber ring 304 and the oral administration connector 102 are made of elastic material. Therefore, when the oral administration connector 102 is fitted into the annular block c303 or the annular block b302, or the bottom outer side of the annular block a301, the elasticity of the rubber ring 304 can fix the oral administration connector 102 to the annular block c303 or the annular block b302, or the bottom outer side of the annular block a301, and can seal the gap between the oral administration connector 102 and the annular block c303 or the annular block b302, or the annular block a301, thereby completing the installation of the oral administration connector 102.

[0029] The movable cavity 103 is equipped with a mounting block 4. An L-shaped connecting pipe 402 is fixedly connected to the top of the mounting block 4. A limiting groove 106 is opened on one side of the equipment cavity 101. A through hole 107 is opened at the bottom of the inner wall of the equipment cavity 101. One end of the L-shaped connecting pipe 402 passes through the through hole 107 and the limiting groove 106 and is fixedly connected to the mounting box 5. A pressure sensor 401 is fixedly connected to the bottom of the mounting block 4. A rubber sleeve 403 is fitted on the outside of the L-shaped connecting pipe 402.

[0030] In use, the bottom end of the oral administration connector 102 can be inserted into the medication, and button 7 can be pressed. Button 7 controls the electric push rod 2 to retract, thereby driving the piston 201 to move upward along the inner wall of the moving cavity 103. Since the bottom end of the oral administration connector 102 is located inside the medication, and the piston 201 seals the main connector 105 of the medication dispenser, a sealed space is formed between the main connector 105 and the oral administration connector 102. Therefore, when the piston 201 moves upward, the sealed space increases. At this time, the liquid cannot be instantly replenished to fill the increased space, which results in low pressure inside the sealed space. The pressure from the external environment forces the medication into the oral delivery connector 102. When the piston 201 moves upward to the specified distance, it squeezes the pressure sensor 401, causing the pressure sensor 401 to generate an electrical signal. This signal is then transmitted to the microcontroller 503, which shuts off the electric push rod 2, stopping the piston 201 from moving upward. Simultaneously, the microcontroller 503 controls the speaker 504 to emit a pre-recorded sound from the recording module 502, reminding the user that the required dosage of medication has been reached inside the oral delivery connector 102.

[0031] Furthermore, when medication needs to be administered, the oral administration connector 102 can be held in the mouth, and button 7 can be pressed to control the electric push rod 2 to drive the piston 201 downward, thus pushing the medication out of the oral administration connector 102. After use, the oral administration connector 102 can be directly unplugged for cleaning or replacement.

[0032] Furthermore, the pressure sensor 401 is a piezoelectric pressure sensor, model number 8507C-1. When external pressure is applied to the sensor, the piezoelectric element inside the pressure sensor 401 deforms and generates a corresponding charge. These charges are detected and amplified by appropriate electronic circuitry, ultimately resulting in a voltage or current signal output proportional to the input pressure. This closes the electric push rod 2, stops the upward movement of the piston 201, and activates the speaker 504. This solution does not improve the circuitry or program of the pressure sensor 401, therefore, the circuitry and signal connection relationships of the pressure sensor 401 will not be described in detail.

[0033] The device housing 1 is fixedly connected to a positioning plate 603 on one side. A knob 604 is provided below the positioning plate 603. A threaded rod 602 is fixedly connected to the bottom of the knob 604. A threaded hole that mates with the threaded rod 602 is opened on the top of the positioning plate 603. A fixing plate 601 is connected to the top of the threaded rod 602 through a bearing. A rectangular frame 6 is fixedly installed on the top of the fixing plate 601, and the mounting box 5 is located inside the rectangular frame 6.

[0034] When it is necessary to adjust the dosage drawn by the oral administration connector 102, the knob 604 can be turned to rotate the threaded rod 602 in the threaded hole on the positioning plate 603. This causes the rectangular frame 6 and the mounting box 5 to move up or down on one side of the drug delivery device housing 1, and also causes the L-shaped connecting tube 402, the mounting block 4, and the pressure sensor 401 to move up or down in the moving cavity 103. The drug delivery device housing 1 has a scale on one side. The user can refer to the scale to move the mounting box 5 to a suitable position, and then adjust the position of the mounting block 4 in the moving cavity 103 so that the piston 201 can contact the pressure sensor 401 in a suitable position, and control the electric push rod 2 to close, thereby stopping the extraction of the drug and controlling the dosage of the drug drawn by the oral administration connector 102.

[0035] The installation box 5 contains a battery 501 and a recording module 502. A microcontroller 503 is installed on one side of the recording module 502, and a speaker 504 is installed on the top of the microcontroller 503. Two buttons 7 are installed on the top of the drug delivery device housing 1. The recording module 502 can record prompts, and the speaker 504 can play the recorded sounds.

[0036] The working principle is as follows:

[0037] In use, different specifications and styles of oral drug delivery connectors 102 can be selected according to needs. The annular block c303 is rotated, causing the annular block b302, annular block a301, and annular connecting block 3 to rotate inside the threaded cavity 104. This causes the annular connecting block 3 to move downwards, thereby causing the annular block b302 or annular block a301 to move downwards. Then, the bottom end of the main connector 105 of the drug delivery device is inserted into the oral drug delivery connector 102, and the oral drug delivery connector 102 is fitted onto the annular block c303 or annular block b302, or the bottom outer side of the annular block a301. Due to the elastic rubber... Both the rubber ring 304 and the oral administration connector 102 are made of elastic material. Therefore, when the oral administration connector 102 is fitted into the annular block c303 or the annular block b302, or the bottom outer side of the annular block a301, the elasticity of the rubber ring 304 can fix the oral administration connector 102 to the annular block c303 or the annular block b302, or the bottom outer side of the annular block a301, and can seal the gap between the oral administration connector 102 and the annular block c303 or the annular block b302, or the annular block a301, thereby completing the installation of the oral administration connector 102.

[0038] Furthermore, the bottom end of the oral administration connector 102 can be inserted into the medication, and button 7 can be pressed. Button 7 controls the electric push rod 2 to retract, thereby driving piston 201 to move upward along the inner wall of the moving cavity 103. Since the bottom end of the oral administration connector 102 is located inside the medication, and piston 201 seals the main connector 105 of the medication dispenser, a sealed space is formed between the main connector 105 and the oral administration connector 102. Therefore, when piston 201 moves upward, the sealed space increases. At this time, liquid cannot be instantly replenished to fill the increased space, which results in low pressure inside the sealed space. The pressure from the external environment forces the medication into the oral delivery connector 102. When the piston 201 moves upward to the specified distance, it squeezes the pressure sensor 401, causing the pressure sensor 401 to generate an electrical signal. This signal is then transmitted to the microcontroller 503, which shuts off the electric push rod 2, stopping the piston 201 from moving upward. Simultaneously, the microcontroller 503 controls the speaker 504 to emit a pre-recorded sound from the recording module 502, reminding the user that the required dosage of medication has been reached inside the oral delivery connector 102.

[0039] Furthermore, the recording module 502 can record the prompt sound, and the speaker 504 can play the recorded sound.

[0040] When medication needs to be administered, the oral administration connector 102 can be held in the mouth and the button 7 can be pressed to control the electric push rod 2 to move the piston 201 downward, and the medication can be pushed out of the oral administration connector 102 at a uniform speed. After use, the oral administration connector 102 can be directly unplugged to clean or replace it.

[0041] When it is necessary to adjust the dosage drawn by the oral administration connector 102, the knob 604 can be turned to rotate the threaded rod 602 in the threaded hole on the positioning plate 603. This causes the rectangular frame 6 and the mounting box 5 to move up or down on one side of the drug delivery device housing 1, and also causes the L-shaped connecting tube 402, the mounting block 4, and the pressure sensor 401 to move up or down in the moving cavity 103. The drug delivery device housing 1 has a scale on one side. The user can refer to the scale to move the mounting box 5 to a suitable position, and then adjust the position of the mounting block 4 in the moving cavity 103 so that the piston 201 can contact the pressure sensor 401 in a suitable position, and control the electric push rod 2 to close, thereby stopping the extraction of the drug and controlling the dosage of the drug drawn by the oral administration connector 102.

[0042] In addition, button 7 can control the power supply to the electric actuator 2, pressure sensor 401, recording module 502, microcontroller 503 and speaker 504.

[0043] The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art, and this part is not the innovation of this utility model.
