Description

Technical Field

[0001] This utility model relates to the field of medical nursing technology, and in particular to a nursing medication delivery device. Background Technology

[0002] In the healthcare field, medication administration facilities are critical for ensuring accurate and safe medication delivery to patients, especially those requiring special care, such as children, the elderly, critically ill patients, and those with dysphagia. They typically rely on a variety of technologies and components to function.

[0003] 1. Medicine container or medicine cup: Used to store medicines to be fed. The material must be chemically stable to ensure that the medicines do not deteriorate. Common materials include plastic and glass, and there are various sizes available to suit the storage needs of different dosages of medicines.

[0004] 2. Medication delivery tubing: This tubing is used to deliver medication. It generally requires a certain degree of flexibility so that the angle and position can be easily adjusted in different medication delivery scenarios. At the same time, its inner wall should be smooth to prevent drug residue from clogging the tubing. It is often made of medical-grade silicone or similar materials.

[0005] 3. Control device: Responsible for regulating the drug delivery process, such as setting the dosage and controlling the delivery speed. Some use a simple mechanical knob structure, which adjusts the output of the drug precisely by rotating it; others are equipped with an electronic control panel, which uses a microcomputer chip to process data and achieve more intelligent control.

[0006] Currently, to meet the medication delivery needs of caregivers and patients, various manufacturers have developed a variety of medication delivery mechanisms. Some manufacturers have introduced traditional syringe-type medication delivery devices, which utilize the principle of a syringe to achieve rapid medication delivery through a push-pull piston. This method is simple and direct to operate, and can quickly inject medication into the patient's mouth in emergencies. However, its disadvantage is that it is difficult to accurately control the medication dosage, making it unsuitable for some medications with strict dosage requirements. Other manufacturers have designed dropper-based medication delivery devices, which use squeezing the dropper to make the medication flow out drop by drop. This can control the dosage to some extent, but the delivery speed is too slow and the efficiency is low, making it inadequate for scenarios where large amounts of medication need to be administered urgently.

[0007] However, the existing medication delivery mechanisms still have the following problems: In terms of precise medication delivery, although some devices attempt to control the dosage through mechanical structures or electronic components, they are either not precise enough or cumbersome to operate, and cannot meet the precise requirements of clinical use for some special drugs (such as cardiotonics, antiepileptic drugs, and other drugs with extremely high dose sensitivity). Moreover, a single medication delivery method is difficult to take into account the diverse needs of patients with different conditions and age groups. In response to this problem, this application proposes a solution: designing a nursing medication delivery mechanism that combines rotary precision delivery and rapid delivery. This mechanism can achieve high-precision control of drug dosage through rotational operation, and can also quickly complete the medication delivery task in emergency situations. It is easy to operate, highly adaptable, and can meet the medication delivery needs of different patient groups. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model provides a nursing medication feeding mechanism, which solves the problem that it cannot meet the precise requirements of clinical practice for some special drugs in terms of accurate medication feeding, and that a single medication feeding method is difficult to take into account the diverse needs of patients with different conditions and different age groups.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A medication delivery mechanism for nursing care includes a medication cartridge. A dispensing head for dispensing liquid is fixedly connected to the lower surface of the medication cartridge. A piston for squeezing out medication is movably sleeved inside the medication cartridge. A connecting post is fixedly connected to the upper surface of the piston. A knob is provided above the medication cartridge. A screw for driving is fixedly connected to the lower surface of the knob. A set of scales is provided on the annular side of the medication cartridge. Two limiting blocks are fixedly connected to the lower surface of the knob for limiting its movement. Two connecting blocks are fixedly connected to the annular side of the connecting post to ensure its fixed position when moving inside the medication cartridge. A rubber cover for maintaining stability during medication delivery is fixedly connected to the lower end of the medication cartridge. The rubber cover will fit against the patient's cheek to ensure stability during medication delivery.

[0011] Preferably, the cartridge has two pull rings fixedly connected to its annular side. The upper surfaces of the connecting column and the piston are both provided with threaded holes, and the two threaded holes are connected to each other. Both threaded holes are threadedly connected to the screw. The inner wall of the cartridge has two slots, which are respectively engaged with two connecting blocks. By hooking the two pull rings and pressing the knob to move downward, the connecting column and the piston move together, thus meeting the need for rapid drug delivery.

[0012] Preferably, the upper surface of the cartridge has two limiting grooves, which are respectively engaged with two limiting blocks. The annular side of the cartridge has an annular groove that communicates with the two limiting grooves and is movably connected to the two limiting blocks. The annular side of the knob has a set of grooves to improve friction. By slowly rotating the knob and observing the scale, the flow rate and dosage of the medicine can be precisely controlled, thereby ensuring the effectiveness of its therapeutic effect.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. As the piston moves, it will squeeze the liquid medicine in the cartridge out of the dispensing head. At this time, the dispensing head is placed into the patient's mouth. The rubber cover will also fit against the patient's cheek to ensure stability during the medication administration process. By slowly turning the knob and observing the scale, the flow rate and dosage of the liquid medicine can be precisely controlled, thereby ensuring the effectiveness of the treatment and meeting the usage requirements.

[0015] 2. Pour the prepared appropriate amount of medicine into the cartridge. Then, rotate the connecting column and piston downwards to position them at the lower end of the screw. Place the piston into the cartridge and move it downwards by hooking the two pull rings and pressing the knob. This will move the connecting column and piston together, thus meeting the need for rapid medication. The whole system combines precise rotational medication feeding with rapid medication feeding, improving overall flexibility. Attached Figure Description

[0022] This application provides a nursing medication feeding mechanism that effectively solves the problem of inaccurate medication feeding, which cannot meet the precise requirements of clinical practice for some special drugs. A single medication feeding method is difficult to take into account the diverse needs of patients with different conditions and age groups. The nursing medication feeding mechanism is designed to combine rotary precision feeding and rapid medication feeding. This mechanism can achieve high-precision control of drug dosage through rotation operation, and can quickly complete the medication feeding task in emergency situations. It is easy to operate, highly adaptable, and can meet the medication feeding needs of different patient groups.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that precise medication administration cannot meet the clinical requirements for some special drugs, and that a single medication administration method cannot meet the diverse needs of patients with different conditions and age groups. The overall approach is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a nursing medication feeding mechanism, including a medicine cartridge 1. A dispensing head 3 is fixedly connected to the lower surface of the medicine cartridge 1 for dispensing liquid. A piston 10 for squeezing out liquid medication is movably sleeved inside the medicine cartridge 1. A connecting post 9 is fixedly connected to the upper surface of the piston 10. A knob 6 is located above the medicine cartridge 1. A screw 8 for driving is fixedly connected to the lower surface of the knob 6. A set of scales 4 is provided on the annular side of the medicine cartridge 1. Two limiting blocks 7 are fixedly connected to the lower surface of the knob 6 for limiting its movement. Two connecting blocks 15 are fixedly connected to the annular side of the connecting post 9 to ensure its position is fixed when moving inside the medicine cartridge 1. A rubber cover 2 for maintaining stability during medication feeding is fixedly connected to the lower end of the medicine cartridge 1. During medication feeding, liquid medication is added to the medicine cartridge 1. At this time, the connecting post 9 and the piston 10 fixed thereon are sleeved onto the screw 8. By rotating them upwards, they are positioned at the screw 8. At the upper position, the piston 10 is aligned with the opening on the upper surface of the cartridge 1 for connection. The two connecting blocks 15 fixed on the connecting column 9 are then engaged with the two slots 13 on the inner wall of the cartridge 1. The adjusting knob 6 is then rotated to align the two limiting blocks 7 fixed on its surface with the two limiting slots 12 for engagement. Once engaged, the knob 6 is rotated to drive the fixed screw 8 to rotate together. The connecting column 9 and piston 10, under the action of the threads and limited by the two connecting blocks 15, will move downwards inside the cartridge 1. As the piston 10 moves, it will squeeze the liquid in the cartridge 1 out from the dispensing head 3. The dispensing head 3 is then placed into the patient's mouth. The rubber cover 2 will also fit against the patient's cheek to ensure stability during medication administration. By slowly rotating the knob 6 and observing the scale 4, the flow rate and dosage of the liquid can be precisely controlled, thereby ensuring the effectiveness of the treatment and meeting the usage requirements.

[0026] Two pull rings 5 ​​are fixedly connected to the annular side of the cartridge 1. Threaded holes 14 are opened on the upper surfaces of the connecting post 9 and the piston 10, and these two threaded holes 14 are interconnected. Both threaded holes 14 are threadedly engaged with the screw 8. Two retaining grooves 13 are opened on the inner wall of the cartridge 1, and these two retaining grooves 13 are respectively engaged with two connecting blocks 15. Two limiting grooves 12 are opened on the upper surface of the cartridge 1, and these two limiting grooves 12 are respectively engaged with two limiting blocks 7. An annular groove 11 is opened on the annular side of the cartridge 1, and the annular groove 11 is connected to the two limiting grooves 12 and is movably connected to the two limiting blocks 7. A set of grooves for improving friction is opened on the annular side of the knob 6. Once the appropriate amount of medicine solution has been prepared, rotate knob 6 to align the two fixed limit blocks 7 with the two limit grooves 12 and remove them upwards. At this time, remove the connecting post 9 and piston 10 that are sleeved on the surface of the driving screw 8. After cleaning them, pour the prepared appropriate amount of medicine solution into the medicine cartridge 1. Then, rotate the connecting post 9 and piston 10 downwards so that they are at the lower end of the screw 8. Place the piston 10 into the medicine cartridge 1, hook the two pull rings 5, and press knob 6 to move downwards, thereby moving the connecting post 9 and piston 10 together. This satisfies the need for rapid medicine feeding. The whole system combines precise rotational medicine feeding with rapid medicine feeding, improving overall flexibility.

[0027] Among them, medicine cartridge 1 is used to store the medicine to be fed. Its material has chemical stability and comes in various sizes. It is the main part of the medicine feeding mechanism and provides space for other components to install and hold medicine.

[0028] Rubber cover 2: It is fixedly connected to the lower end of the medicine cartridge 1 and fits against the patient's cheek when administering the medicine, so as to keep the medicine administration process stable;

[0029] Dispensing head 3: Fixedly connected to the lower surface of the medicine cartridge 1, used to discharge the medicine squeezed out of the medicine cartridge 1, so that the medicine can smoothly enter the patient's mouth;

[0030] Scale 4: Located on the annular side of the medicine cartridge 1, when the flow rate and dosage of the medicine are controlled by rotating the knob 6, fine control can be achieved by observing the scale 4 to ensure accurate dosage.

[0031] Pull ring 5: It is fixedly connected to the annular side of the cartridge 1. When rapid feeding is required, hooking the pull ring 5 and pressing the knob 6 can drive the connecting column 9 and piston 10 to move rapidly to meet the needs of rapid feeding.

[0032] Knob 6: Located above the medicine cartridge 1, it rotates to drive the screw 8 to rotate, thereby controlling the movement of the connecting column 9 and the piston 10, so as to adjust the flow rate and dosage of the medicine and enable precise drug delivery.

[0033] Limiting block 7: It is fixedly connected to the lower surface of the knob 6 and cooperates with the limiting groove 12 and the annular groove 11 on the medicine cartridge 1 to limit the rotation of the knob 6, ensuring that it rotates accurately within a certain range and ensuring the stability and accuracy of the medicine feeding operation.

[0034] Screw 8: It is fixedly connected to the lower surface of the knob 6 and threadedly connected to the threaded hole 14 on the connecting post 9 and the piston 10. When the knob 6 is rotated, the screw 8 drives the connecting post 9 and the piston 10 to move inside the cartridge 1 through the thread action, thereby squeezing the medicine liquid.

[0035] Connecting column 9: The upper surface is fixedly connected to the piston 10, and the annular side is fixedly connected to the connecting block 15. The connecting block 15 is movably engaged with the groove 13 on the inner wall of the cartridge 1 to ensure that its position is fixed when it moves inside the cartridge 1. At the same time, it cooperates with the screw 8 to drive the piston 10 to move when the knob 6 is turned, so as to realize the extrusion of the liquid medicine.

[0036] Piston 10: It is movably sleeved inside the medicine cartridge 1, and its upper surface is fixedly connected to the connecting column 9. Driven by the screw 8 and the connecting column 9, it moves and squeezes the medicine liquid in the medicine cartridge 1, so that it is discharged from the liquid outlet 3. It is one of the key components for realizing medicine feeding.

[0037] Annular groove 11: It is formed on the annular side of the cartridge 1 and communicates with the limiting groove 12. It provides a space for the limiting block 7 to move within a certain range, ensuring the smooth rotation of the knob 6, and at the same time playing an auxiliary limiting role.

[0038] Limiting groove 12: It is formed on the upper surface of the medicine cartridge 1 and is movably engaged with the limiting block 7 to limit the initial installation position and rotation range of the knob 6, ensuring that the knob 6 rotates in the correct position, thereby ensuring the accuracy of the medicine feeding operation.

[0039] Slot 13: It is formed on the inner wall of the cartridge 1 and is movably engaged with the connecting block 15 to restrict the rotation of the connecting column 9 in the cartridge 1, so that the connecting column 9 can only move up and down in the cartridge 1, ensuring the accuracy of the movement direction of the piston 10, thereby stably squeezing the liquid medicine.

[0040] Threaded hole 14: It is opened on the upper surface of the connecting column 9 and the piston 10 respectively and is connected to the screw 8. When the screw 8 rotates, it can drive the connecting column 9 and the piston 10 to move in the cartridge 1 to realize the delivery of medicine liquid.

[0041] Connecting block 15: It is fixedly connected to the annular side of the connecting column 9 and is movably engaged with the groove 13 on the inner wall of the cartridge 1 to ensure that the connecting column 9 is fixed in position when it moves inside the cartridge 1, preventing it from rotating, and ensuring that the piston 10 moves linearly inside the cartridge 1 to accurately squeeze the liquid medicine.

[0042] Working principle:

[0043] During medication administration, liquid medicine is added to the cartridge 1. The connecting column 9 and its fixed piston 10 are then fitted onto the screw 8. By rotating them upwards, they are positioned at the upper end of the screw 8. The piston 10 is then aligned with the opening on the upper surface of the cartridge 1, allowing the two connecting blocks 15 fixed on the connecting column 9 to engage with the two slots 13 on the inner wall of the cartridge 1. The adjusting knob 6 is then rotated to align the two limiting blocks 7 fixed on its surface with the two limiting slots 12. Once engaged, the knob 6 is rotated to rotate the fixed screw 8. The connecting column 9 and piston 10, driven by the threads and limited by the two connecting blocks 15, will move downwards within the cartridge 1. As the piston 10 moves, it will compress the liquid medicine within the cartridge 1, expelling it from the dispensing head 3. The dispensing head 3 is then placed into the patient's mouth, and the rubber cover 2 will press against the patient's cheek. To ensure stability during medication administration, the flow rate and dosage of the medication are precisely controlled by slowly rotating knob 6 and observing the scale 4, thereby ensuring the effectiveness of the treatment and meeting the usage requirements. When the appropriate amount of medication has been prepared, rotate knob 6 to align the two fixed limit blocks 7 with the two limit grooves 12 and remove them upwards. Then, remove the connecting post 9 and piston 10 that are sleeved on the surface of the driving screw 8, clean them, and pour the prepared appropriate amount of medication into the medicine cartridge 1. Then, rotate the connecting post 9 and piston 10 downwards to position them at the lower end of the screw 8, put the piston 10 into the medicine cartridge 1, and move it downwards by hooking the two pull rings 5 ​​and pressing knob 6, thereby moving the connecting post 9 and piston 10 together. This meets the need for rapid medication administration. The whole system combines precise rotational medication administration with rapid medication administration, improving the overall flexibility.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
