Description

Technical Field

[0001] This utility model relates to a drug feeding device, belonging to the field of medical device technology. Background Technology

[0002] ICU stands for Intensive Care Unit. Intensive care is a medical organization and management form that integrates modern medical and nursing technologies, which has emerged with the development of medical and nursing professions, the emergence of new medical equipment, and the improvement of hospital management systems. ICU brings together critically ill patients and provides them with the best support in terms of manpower, material resources, and technology in order to achieve good treatment results. Currently, most patients in ICU are bedridden for a long time due to the severity of their condition, which makes it inconvenient for them to move around, and as a result, they need to be fed medication by medical staff.

[0003] Chinese patent document CN219208147U, published on June 20, 2023, discloses a medication feeder for ICU patients. It involves fitting a medication-fixing mask to the patient's face and attaching a feeding nozzle to the mask's surface. The nozzle is connected to a drainage tube at the top and positioned directly above the patient's mouth, allowing medication to enter the drainage tube and then through the nozzle into the patient's mouth. However, as shown in the accompanying drawings, when the tablets enter the dispensing chamber at the bottom via a tilting surface, and then purified water is poured into the inlet, it becomes difficult to clean the liquid adhering to the inner wall of the dispensing chamber after the stirring shaft rotates and dissolves the tablets in the water. This results in some waste. Summary of the Invention

[0004] The purpose of this invention is to provide a medication feeding device to solve the problems mentioned in the background art.

[0005] The present invention adopts the following technical solution:

[0006] A medication feeding device includes a medication storage cylinder 1. The top of the medication storage cylinder 1 is connected to a mixing tank 4 via a pipe 3. The mixing tank 4 is cylindrical, and an electric motor 56 is fixed to its upper part by a bracket. The drive shaft 57 of the electric motor 56 is coaxial with the central axis of the mixing tank 4 and extends into the mixing tank 4. At least one scraping component is connected to the drive shaft 57. The scraping component contacts the inner wall of the mixing tank 4 or leaves a small gap. The bracket is a pressing mechanism 5, which includes a pair of mounting plates 51. A horizontal plate 52 extends inward from the mounting plate 51. The horizontal plate 52 has a through hole for a guide rod 53 to pass through. The upper end of the guide rod 53 is connected to an adjusting plate 55. A spring 54 is sleeved on the outside of the guide rod 53. The upper end of the spring abuts against the adjusting plate 55, and the lower end abuts against the horizontal plate 52. The adjusting plate 55 serves as the fixed base for the electric motor 56.

[0007] Among them, the model of motor 56 is YE2.

[0008] The pressing mechanism 5 causes the spring 54 to undergo elastic deformation by continuously pressing the adjusting plate 55. This not only drives the rotating transmission shaft 57 to move up and down inside the mixing tank 4, which is beneficial for mixing the liquid medicine at different heights evenly, but also drives the rotating scraper 59 to move up and down inside the mixing tank 4, which is beneficial for scraping off the liquid medicine adhering to the inner wall of the mixing tank 4 in a timely manner, reducing the waste of liquid medicine.

[0009] Preferably, the scraping components are a pair, spaced 180° apart.

[0010] Preferably, one end of the medicine storage cylinder 1 is fixedly connected to a flexible tube 2, and a protective cover 21 is fitted over the outside of the flexible tube 2.

[0011] Preferably, the top of the mixing tank 4 is fixedly connected to a dosing port 41, and valves are installed in both the dosing port 41 and the pipe 3.

[0012] Preferably, the scraping component includes two stirring rods 58 and a scraper 59 connected to the end of the stirring rods 58.

[0013] Preferably, the mixing tank 4 has a groove 42 at the top center, and the diameter of the drive shaft 57 is smaller than the diameter of the groove 42.

[0014] Furthermore, an anti-detachment disc is fixed to the bottom end of the guide rod 53.

[0015] Preferably, a gripping mechanism 6 is installed on the medicine storage cylinder 1. The gripping mechanism 6 includes a placement plate 61 and a fastening frame 63. The fastening frame 63 is L-shaped, with one end fixed to the side end of the placement plate 61. A threaded hole that mates with a threaded rod 64 is opened on the other end of the fastening frame 63. One end of the threaded rod 64 extends into the inside of the medicine storage cylinder 1, and a piston 65 is fixed to the end. The placement plate 61 is fixedly connected to the bottom of the medicine storage cylinder 1.

[0016] Furthermore, the bottom of the placement plate 61 is provided with multiple sets of finger grooves 62, and the other end of the threaded rod 64 is fixedly connected to a handle.

[0017] The gripping mechanism 6 can play a certain anti-slip role when pushing the medicine in the medicine storage cylinder 1, preventing the entire medicine feeding device from accidentally falling and injuring the patient, and preventing the medicine from spilling on the patient. Moreover, the rotation of the threaded rod 64 is used to push the medicine, which can avoid pushing the medicine too fast and causing the patient to choke, thus reducing the patient's discomfort when taking medicine.

[0018] The beneficial effects of this invention are as follows:

[0019] 1) The pressing mechanism causes the spring to deform elastically by continuously pressing the adjusting plate. This not only drives the rotating drive shaft to move up and down in the mixing tank, which is beneficial for mixing the liquid medicine at different heights evenly, but also drives the rotating scraper to move up and down on the inner wall of the mixing tank, which is beneficial for timely scraping off the liquid medicine adhering to the inner wall of the mixing tank and reducing the waste of liquid medicine.

[0020] 2) The gripping mechanism can play a certain anti-slip role when pushing the liquid medicine in the medicine reservoir, preventing the entire medicine feeding device from accidentally falling and injuring the patient, and preventing the liquid medicine from spilling on the patient. Moreover, the use of the rotation of the threaded rod to push the liquid medicine can avoid pushing the liquid medicine too fast and causing the patient to choke, reducing the patient's discomfort when taking medicine.

[0031] Working principle: When using this device, the tablets are placed into the mixing tank 4 through the inlet 41, and then an appropriate amount of water is injected into the mixing tank 4 through the inlet 41. Next, the motor 56 is turned on. Once energized, the motor 56 drives the drive shaft 57, stirring rod 58, and scraper 59 to rotate. The user then presses the adjusting plate 55 up and down, which compresses and deforms the spring 54, causing the adjusting plate 55 and motor 56 to move up and down. This, in turn, moves the rotating drive shaft 57, stirring rod 58, and scraper 59 up and down within the mixing tank 4, facilitating the uniform mixing of the liquid at different heights. The mixing process is smooth and even, and at the same time, it can drive the rotating scraper 59 to move up and down on the inner wall of the mixing tank 4, which helps to scrape off the medicine attached to the inner wall of the mixing tank 4 in time and reduce the waste of medicine. After the mixing is completed, the pipe 3 is opened, and the medicine can flow into the medicine storage cylinder 1. Then, one end of the hose 2 is inserted into the patient's mouth, and the protective cover 21 is covered to prevent the medicine from spilling. Then, the fingers of one hand are placed into the multiple finger grooves 62, and the other hand holds the handle on the threaded rod 64 and rotates it. At this time, the piston 65 can be driven to move to the left continuously in the medicine storage cylinder 1, thereby injecting the medicine into the patient's mouth through the hose 2, thus completing the medication feeding process.

[0032] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
