Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an intelligent liquid preparation table with a medicine identification function. Background Art

[0002] In the field of medical dispensing, the traditional dispensing method has many problems, which provides an urgent need for the emergence of intelligent dispensing platforms with drug identification functions;

[0003] In the past, the work of dispensing liquids mainly relied on manual operation by medical staff. When dispensing liquids manually, medical staff need to check the information of the dispensing bottle and the infusion bottle one by one, and then transfer the medicine from the dispensing bottle to the infusion bottle. This process is not only time-consuming and labor-intensive, but also prone to human errors. For example, in a busy working environment, medical staff may take the wrong medicine due to fatigue or negligence, resulting in dispensing errors, which may have serious adverse effects on the patient's treatment. In addition, manual dispensing is inefficient and it is difficult to meet the dispensing needs of a large number of patients in the hospital, especially in the case of emergency treatment or concentrated inpatients. The slow dispensing speed will delay the patient's treatment time;

[0004] In terms of health and safety, the disinfection process of the traditional liquid preparation method also has shortcomings. Manual disinfection usually relies on medical staff to wipe with disinfectants, etc., which makes it difficult to ensure the comprehensiveness and standardization of disinfection. In addition, due to the presence of various microorganisms in the liquid preparation environment, bacteria, viruses and other pathogens are easily introduced during manual operation, increasing the risk of drug contamination, thereby affecting the safety of patients' medication.

[0005] With the continuous development of medical technology and people's increasing requirements for medical quality, the traditional manual liquid preparation method can no longer meet the needs of modern medical care. Therefore, it is urgent to develop an intelligent liquid preparation station that can automatically prepare and disinfect liquid preparation bottles and infusion bottles. It is expected to solve the problems of low efficiency, poor accuracy and health and safety hazards of manual liquid preparation, and provide patients with more efficient and safer medical services.

[0006] Chinese patent (publication number CN102973377B), which discloses a medical clinical infusion aseptic automatic dispensing workbench, the main working area includes a vial opening system, an ampoule opening system, and an automatic dispensing system. There are at least a group of vial and ampoule placement holes on the sliding platform, and cylinders with openings of various specifications are connected below. There is a rotatable shaft in the same direction next to each group of cylinders, and a group of torsion springs are fixed on the shaft. The steel wire at the other end of the torsion spring is placed in the cylinder opening. A connecting rod is fixed on each rotating shaft and then connected to a cross bar. A motor is connected to one of the rotating shafts to form a group of linked bottle disposal devices. The upper part is a canopy, and the purified air outlet is connected to the air purification system. The invention is used for air disinfection in the dispensing room and local air purification to meet the requirements of Class 100 purification, and automatically opens the vials and ampoule bottles, disinfects the main surface of the medicine bottle, and can automatically dispense medicine.

[0007] According to the above scheme, it can be known that in actual application, the above scheme can automatically complete a series of operations such as opening, disinfecting and dispensing medicine bottles, without manual intervention throughout the process. However, when dispensing medicines for infusion bottles and preparation bottles, if conventional disinfection methods are used, incomplete disinfection will occur, and it is difficult to ensure the hygienic safety of medicines during the preparation process. In order to solve the problem of incomplete disinfection when dispensing medicines for infusion bottles and preparation bottles, if conventional disinfection methods are used, we propose an intelligent preparation station with drug recognition function.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1 to 5As shown, in an embodiment of the present invention, an intelligent dispensing table with a drug identification function includes a table 1, two electric telescopic legs 4 are fixedly connected to the bottom of the table 1, and the electric telescopic legs 4 can facilitate personnel to adjust the height of the table 1, and the upper end of the table 1 is fixedly connected to a shelf 3, and the shelf 3 is fixedly connected to a display screen 5 inside. The upper end of the table 1 is also fixedly connected to a plurality of display boxes 6 for storing infusion bottles, and the plurality of display boxes 6 are distributed in an array from left to right at the upper end of the table 1. The front end of each display box 6 is fixedly connected to a display sub-screen 7 for displaying a label name, and the upper end of the table 1 is also fixedly connected to a scanner 2, which can scan the QR code on the outer surface of the infusion bottle. , and then the bed number, name, infusion type, etc. are displayed on the display screen 5. The upper end of the table 1 is also fixedly connected to two bases 11, and the upper end of the base 11 is fixedly connected to a fixing mechanism 101 for fixing the medicine bottle. The upper end of the base 11 is also fixedly installed with a liquid preparation mechanism 201 for preparing liquid for the medicine bottle and the infusion bottle. The upper end of the base 11 is fixedly connected to a casing 13, and an observation window 12 is provided on the outer wall of the casing 13. The lower end of the table 1 is slidably connected to an extended table board 8. Through this design, the use area of ​​the table 1 can be effectively increased, thereby providing a larger operating space. At the same time, when the staff takes the infusion bottle, it can prevent the infusion bottle from accidentally falling to the ground.

[0038] Example 2: Please refer to Figures 4 to 9 , Fig.12As shown, the liquid dispensing mechanism 201 includes a connecting frame 19, which is fixedly connected to the upper end of the base 11, and a gas tank 15 is fixedly connected to the upper end of the connecting frame 19. The gas tank 15 is filled with nitrogen. Nitrogen is an inert gas with extremely inactive chemical properties. At normal temperature and pressure, it hardly reacts chemically with any drug ingredients. In the infusion bottle, if nitrogen is filled, it will not react with the drug such as oxidation-reduction, acid-base neutralization, etc., and can well maintain the chemical stability of the drug. The upper end of the connecting frame 19 is also fixedly connected to an electric telescopic arm 22, and the output end of the electric telescopic arm 22 is fixedly connected to a mobile frame 21. The upper end of the inner wall of the mobile frame 21 is fixedly connected to a ventilation pipe 30, and one end of the mobile frame 21 away from the electric telescopic arm 22 is fixedly connected to two corrugated sleeves 27, and the two corrugated sleeves 27 are symmetrically distributed on the outer wall of the mobile frame 21. The corrugated sleeve 27 is made of rubber material, which has good corrosion resistance and high temperature resistance, and also has good elasticity. It can be reset faster after being compressed. The left end of the inner wall of each corrugated sleeve 27 is fixedly connected to a second needle tube 29, and the two second needle tubes 29 are fixedly connected through a matching tube 28, and the matching tube 28 is "U" shaped. The matching tube 28 is located inside the movable frame 21. The left end of the inner wall of a corrugated sleeve 27 adjacent to the ventilation pipe 30 is also fixedly connected to a first needle tube 25. The first needle tube 25 is located directly above the adjacent second needle tube 29. The first needle tube 25 is connected to the ventilation pipe 30. The upper end of the movable frame 21 is also slidably connected to a first abutment plate 34 with a reset function. A second elastic telescopic arm 35 is connected between the first abutment plate 34 and the movable frame 21. The second elastic telescopic arm 35 can drive the first abutment plate 34 to be quickly reset.

[0039] An abutment tube 18 is fixedly connected to the upper end of the first abutment plate 34, and the abutment tube 18 is adapted to the vent pipe 30. The abutment tube 18 is fixedly connected to the gas tank 15 via a connecting tube 17, and the connecting tube 17 is also made of rubber material, which has good ductility and smaller elastic force than the second elastic telescopic arm 35. A heating box 31 is fixedly connected to the inner wall of the mobile frame 21, and the corrugated sleeve 27 located above the mobile frame 21 is connected to the heating box 31. A plurality of heating copper tubes 32 are fixedly connected to the inside of the heating box 31. The inside of the heating box 31 is filled with a hydrogen peroxide solution. After the hydrogen peroxide solution is heated, its decomposition speed is accelerated, and new ecological oxygen with strong oxidizing properties will be generated. This new ecological oxygen can destroy the cell walls, cell membranes and various biologically active components in cells of microorganisms such as bacteria and viruses, such as proteins and nucleic acids. A number of heating copper tubes 32 are arranged in a row from front to back in the inner wall of the heating box 31. The heating copper tubes 32 are made of copper. The copper material has good corrosion resistance, high temperature resistance and strong thermal conductivity. The outer wall of the mobile frame 21 and the gas tank 15 are fixedly installed with a barometer 16 for detecting the internal pressure. The bottom of the table 1 is fixedly connected to a water tank. The bottom of the corrugated sleeve 27 located below the first needle tube 25 is fixedly connected to the water tank through a corrugated tube 33. The corrugated tube 33 is also made of rubber material, which will not be described in detail here.

[0040] The end of each corrugated sleeve 27 away from the movable frame 21 is fixedly connected to the third abutment plate 26, and the end of the third abutment plate 26 located above the movable frame 21 away from the corrugated sleeve 27 is fixedly connected to the ventilation box 37. The third abutment plate 26 and the ventilation box 37 are fixedly connected with a rubber sealing ring 36. The rubber sealing ring 36 is made of fluorosilicone. Fluorosilicone has stronger heat resistance and can usually withstand higher temperatures even above 300°C. It also has stronger corrosion resistance to chemical substances. Four first elastic telescopic arms 23 are also fixedly connected to the upper end of the connecting frame 19. The outer wall of the first elastic telescopic arm 23 is rotatably connected to the abutment wheel 24 through a rotating shaft. The upper end of the connecting frame 19 is fixedly connected to the fourth elastic telescopic arm 48. The upper end of the fourth elastic telescopic arm 48 is fixedly connected to the third elastic telescopic arm 47. The upper end of the third elastic telescopic arm 47 is provided with a curved surface. The third elastic telescopic arm 47 is located directly below two adjacent abutment wheels 24.

[0041] See also Figure 10-11As shown, the fixing mechanism 101 includes a sliding plate 44 with a reset function, and the sliding plate 44 is slidably connected to the upper end of the connecting frame 19. Specifically, a slide bar is fixedly connected to the upper end of the connecting frame 19, and a slide groove is provided at the bottom of the sliding plate 44. The inner wall of the slide groove is slidably connected to the outer wall of the slide bar. When the sliding plate 44 moves on the outer wall of the slide bar through the slide groove, the slide bar can limit the sliding plate 44 through the slide groove, and also has a guiding function, thereby improving the stability of the sliding plate 44 when moving. The outer wall of the slide bar and the inner wall of the slide groove are both coated with lubricating oil, which can effectively reduce the friction between the slide bar and the slide groove, thereby extending the service life of the slide groove and the slide bar. A reset spring 46 is fixedly connected between the sliding plate 44 and the connecting frame 19; the upper end of the connecting frame 19 is also rotatably connected to a second abutting plate 40 Two swing arms 41 are rotatably connected between the second abutment plate 40 and the sliding plate 44, and the two swing arms 41 are symmetrically distributed front to back between the sliding plate 44 and the second abutment plate 40. Two abutment arms 42 are rotatably connected to the inner wall of the second abutment plate 40, and the two abutment arms 42 are symmetrically distributed front to back inside the second abutment plate 40. A clamping curved block 38 is fixedly connected to the upper end of each abutment arm 42, and a rubber pad is fixedly connected to the opposite ends of the two clamping curved blocks 38. The rubber pad can enhance the friction force on the outer wall of the medicine bottle, and the clamping curved block 38 is curved. An abutment ball 43 is also fixedly connected to the bottom of the abutment arm 42, and the abutment ball 43 can effectively reduce the friction force between the matching plate 45 and the abutment arm 42, thereby extending the service life of the matching plate 45 and the abutment arm 42.

[0042] The upper end of the second abutting plate 40 is fixedly connected with an abutting block 39, which is matched with the abutting tube 18. When the abutting tube 18 abuts against the abutting block 39, the abutting tube 18 is pushed, and the abutting tube 18 drives the first abutting plate 34 to move on the upper end of the moving frame 21, and the abutting tube 18 is connected with the ventilation pipe 30.

[0043] See also Figure 3 to Figure 5 As shown, a placement box 10 is fixedly connected to the upper end of the base 11, and an abutting curved block 20 is fixedly connected to the left end of the inner wall of the placement box 10. The placement box 10 assembly can effectively limit the bottle body of the infusion bottle, thereby ensuring the stability of the bottle body during use. At the same time, the abutting curved block 20 assembly can limit the bottleneck part of the infusion bottle and provide a lifting function to ensure the fixation and support of the bottleneck, thereby ensuring the safety and stability of the entire infusion bottle during operation.

[0044] The working principle of the present invention is:

[0045] When the present invention is used, the infusion bottles that need to be prepared are placed in the display box 6 for arrangement, and when the infusion bottles need to be prepared, the infusion bottles only need to be placed at the bottom of the scanner 2, and the scanner 2 scans the QR code, stripe code or serial number on the outer wall of the infusion bottle, and then displays it on the display screen 5;

[0046] After the scanning is completed, it is only necessary to place the infusion bottle inside the placement box 10. At this time, the infusion bottle has been limited, and then the infusion bottle that needs to be prepared is placed between the two clamping curved blocks 38. The bottom of the preparation bottle abuts against the upper end of the second abutment plate 40. At this time, the electric telescopic arm 22 is started, and the electric telescopic arm 22 will drive the movable frame 21 to move in the direction of the second abutment plate 40. Before starting the electric telescopic arm 22, it is necessary to heat the heating box 31 and the hydrogen peroxide solution inside the corrugated sleeve 27 through the heating copper tube 32. In the process of the electric telescopic arm 22 extending and driving the movable frame 21 to move, the movable frame 21 will drive the abutment tube 18 to move. When the outer wall of the abutment tube 18 abuts against the outer walls of the two nearest abutment wheels 24, the abutment tube 18 is blocked from moving, and the abutment tube 18 will be connected to the ventilation pipe 30, and the gas tank 15 The internal gas will enter the vent pipe 30 through the connecting pipe 17 and the abutting pipe 18. Since there is a hydrogen peroxide solution inside the bellows 27 located above the mobile frame 21, the gas will also enter 25 and the bellows 27 from the inside of the vent pipe 30. The bellows 27 and the heating box 31 are connected. When the gas enters the bellows 27, the pressure inside the bellows 27 and the heating box 31 increases, and the hydrogen peroxide solution will flow to the inside of the bellows 27 at the bottom through the second needle tube 29 and the matching tube 28, and then be discharged from the bellows 33 to the inside of the water tank, completing the disinfection of all the matching tubes 28, the first needle tube 25 and the second needle tube 29. It is worth noting that the time required for hot water to pass through the matching tube 28 is kept at eight to ten seconds, which is enough to achieve a better disinfection effect on all the first needle tubes 25 and the second needle tubes 29;

[0047] When the outer wall of the abutment tube 18 is out of contact with the two nearest abutment wheels 24, the movable frame 21 continues to move, and the ventilation box 37 will abut against the curved surface at the upper end of the third elastic telescopic arm 47, and the corresponding corrugated sleeve 27 will shrink. At this time, the first needle tube 25 and the second needle tube 29 will pass through the rubber sealing ring 36 inside the third abutment plate 26 and enter the ventilation box 37. At the same time, the outer wall of the abutment tube 18 will abut against the outer walls of the other two abutment wheels 24, and the gas will be discharged from the first needle tube 25. When the gas is inside the ventilation box 37, it will be discharged from the second needle tube 29 into the matching tube 28, and then discharged from the matching tube 28 to the other second needle tube 29. The gas enters the bottom of the bellows sleeve 27, and then returns to the water tank through the bellows 33. In this way, the water in all the matching tubes 28, the first needle tube 25 and the second needle tube 29 is drained. Note that when the air box 37 is full of gas, the gas in the air box 37 cannot pass through the rubber sealing ring 36. The rubber sealing ring 36 has good sealing performance. At this time, the electric telescopic arm 22 continues to push the moving frame 21 to move, and the abutment tube 18 will be separated from the abutment with the first elastic telescopic arm 23. The first abutment plate 34 will drive the abutment tube 18 to reset, and the third elastic telescopic arm 47 will shrink downward and be separated from the abutment with the bottom of the air box 37.

[0048] The moving frame 21 continues to move and pushes the third elastic telescopic arm 47 to abut against and push the fourth elastic telescopic arm 48. The fourth elastic telescopic arm 48 will shrink. When the outer wall of the third elastic telescopic arm 47 abuts and pushes the sliding plate 44 and the matching plate 45, the matching plate 45 will abut against the outer walls of the two abutting balls 43. The two abutting arms 42 will drive the clamping curved arc block 38 to clamp the outer wall of the liquid preparation bottle. The sliding plate 44 continues to be pushed. The sliding plate 44 will drive the second abutting plate 40 and the fixed liquid preparation bottle to tilt through the swing arm 41. The liquid medicine inside the liquid preparation bottle will accumulate in the bottle mouth. Then the ventilation box 37 located at the upper end of the moving frame 21 will abut against the bottle mouth of the liquid preparation bottle, and the third abutting plate 26 located at the bottom of the moving frame 21 will abut against the bottle mouth of the infusion bottle. The moving frame 21 will drive the first needle tube 25 and the second needle tube 29 to penetrate through all the rubber sealing rings 36 and pierce into the infusion bottle and the liquid preparation bottle. The first needle tube 25 and the second needle tube 29 pierce the rubber sleeves at the mouths of the preparation bottle and the infusion bottle, and the distance between one end passing through the rubber sleeve and the rubber sleeve is about three to five millimeters. At the same time, the abutment tube 18 will also abut against the abutment block 39. Note that the abutment tube 18 abuts against the abutment block 39 only after the first needle tube 25 and the second needle tube 29 pierce the rubber sleeve. The abutment tube 18 abuts against the abutment block 39, and the abutment tube 18 is pushed. According to the above working principle, nitrogen enters the preparation bottle. Due to the increase in the air pressure inside the preparation bottle, the medicine inside the preparation bottle will be squeezed into the second needle tube 29, and then flow to the other second needle tube 29 through the matching tube 28, and then flow from the second needle tube 29 to the inside of the infusion bottle. When the infusion bottle and the preparation bottle are preparing liquid, a pressure difference will be generated due to the suction action. Under normal circumstances, a small amount of air is easily mixed in, thereby causing air pollution. However, this device, with its unique design, completely avoids the problem of air contact during the liquid preparation process, effectively ensures the cleanliness of the liquid preparation environment, minimizes the risk of drugs being contaminated by air, and provides patients with safer and more reliable medication protection;

[0049] After the liquid preparation is completed, the electric telescopic arm 22 drives the moving frame 21 to reset, and the moving frame 21 will drive all the first needle tubes 25 and the second needle tubes 29 to be pulled out from the rubber sleeves of the infusion bottle and the liquid preparation bottle. At this time, during the resetting process of the moving frame 21, the third abutment plate 26 and the corrugated sleeve 27 will both be separated from the abutment with the bottle mouths of the infusion bottle and the liquid preparation bottle, and the corrugated sleeve 27 will be reset, and the first needle tube 25 and the second needle tube 29 will return to the inside of the corrugated sleeve 27. When the moving frame 21 is reset, the outer wall of the abutment tube 18 is still in abutment with the first elastic telescopic arm 23, but it will not push the abutment tube 18. When the electric telescopic arm 22 drives the moving frame 21 to reset, the next liquid preparation can be carried out. During the whole process, the first needle tube 25 and the third abutment plate 26 are not exposed to the air, and they will be sterilized and air-dried at high temperature before use.
