Description

Technical Field

[0001] The present invention belongs to the technical field of medical infusion, and in particular relates to an infusion device for neurosurgical nursing. Background Art

[0002] As an important tool for clinical treatment, the infusion device plays an indispensable role in neurosurgical nursing. For example, the publication number: CN115990300B discloses an infusion device for neurosurgical nursing.

[0003] Currently, in the neurosurgical nursing scenario, in most cases, ordinary infusion tubes are used for patients during infusion. However, during the infusion process, according to the principle of fluid mechanics, as the liquid medicine in the medicine bottle gradually decreases, the liquid level in the bottle drops, and the hydrostatic pressure decreases accordingly. The hydrostatic pressure is the main driving force for the liquid medicine to flow in the infusion tube, and its decrease will cause the infusion speed to gradually slow down. Taking a 250ml glass infusion bottle as an example, initially the liquid level height in the bottle is about 20cm. When the liquid medicine in the bottle is consumed and the liquid level drops to 5cm, the infusion speed will drop significantly from the original stable 50 drops per minute to 25 drops per minute. An overly slow infusion speed will delay the exertion of the drug efficacy and greatly increase the risk of the patient's condition worsening, which is extremely unfavorable for the patient's recovery; in addition, neurosurgical patients usually need to infuse multiple drugs, and the number of medicine bottles is relatively large. In the busy nursing work, medical staff are prone to taking the wrong medicine bottle, resulting in the inability to match the medicine and the patient information. Medication errors will not only delay the treatment but may also lead to serious medical accidents. The existing infusion device lacks an effective anti-error mechanism and is difficult to perform real-time and accurate verification of the medicine and patient information, further exacerbating the infusion safety risk.

[0004] Therefore, an infusion device for neurosurgical nursing is proposed. Summary of the Invention

[0016] Preferably, the label recognition mechanism includes a mounting plate fixedly arranged on the side wall of the mounting bracket, an RFID label reader is fixedly arranged on the side surface of the mounting plate, and the RFID label reader is located on one side below the weighing hook.

[0017] Preferably, the automatic speed reduction mechanism includes a box body fixedly arranged on the side wall of the mounting bracket, through openings are arranged at the top and bottom of the box body, two moving plates are symmetrically arranged inside the box body, a sliding rod horizontally fixed inside the box body and slidably connected to the two moving plates, clamping plates are fixedly arranged on the opposite sides of the two moving plates, a second motor is fixedly arranged on the inner side wall of the box body, a gear is fixedly arranged at the output shaft of the second motor, racks are meshed with the upper and lower sides of the gear, and one ends of the two racks are respectively fixedly connected to the side surfaces of the two moving plates.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0032] As Figures 1-6 shown, an infusion device for neurosurgical care includes a base 1, a support rod 2, and a support plate 3. The base 1 is fixedly arranged at the lower end of the support rod 2, and the support plate 3 is fixedly arranged at the upper end of the support rod 2. The support rod 2 is a hollow rod, and the inside of the support rod 2 is used for arranging circuits to ensure that the devices at the upper end of the support rod 2 can be powered on and the circuits are not exposed. It further includes:

[0033] A weighing hook 4, which is arranged below the support plate 3, and the weighing hook 4 is used to lift the medicine bottle. The weighing hook 4 can not only hang the medicine bottle for infusion, but also weigh the medicine bottle and the infusion tube.

[0034] The electromagnetic lifting mechanism 5 is arranged at the upper end of the weighing hook 4, and the electromagnetic lifting mechanism 5 is used to drive the weighing hook 4 to rise. The electromagnetic lifting mechanism 5 includes a cylinder body 51. A through electromagnetic block 52 is fixedly arranged on the inner wall of the top of the cylinder body 51. A spring 53 is fixedly arranged at the bottom of the through electromagnetic block 52. The lower end of the spring 53 is fixedly provided with a permanent magnetic block 54, and the permanent magnetic block 54 is slidably connected with the inner wall of the cylinder body 51. A weighing sensor 55 is fixedly arranged at the bottom of the permanent magnetic block 54. The upper end of the weighing hook 4 extends into the interior of the cylinder body 51 and is fixedly connected with the bottom of the weighing sensor 55. After the through electromagnetic block 52 is powered on, the internal current gradually increases. As the current increases, the magnetic adsorption force of the through electromagnetic block 52 on the permanent magnetic block 54 gradually increases. Under the action of the adsorption force, the permanent magnetic block 54, the weighing sensor 55 and the weighing hook 4 overcome the elastic force of the spring 53 and slowly move upward, thereby driving the medicine bottle to rise. When the through electromagnetic block 52 is not powered on, under the action of the elastic force of the spring 53, the permanent magnetic block 54 and the weighing sensor 55 always move downward and are closely attached to the inner wall of the cylinder body 51; Limiting blocks 56 are fixedly arranged on both sides of the permanent magnetic block 54. Limiting grooves matched with the limiting blocks 56 are arranged on the inner side wall of the cylinder body 51. The cooperation between the limiting blocks 56 and the limiting grooves can prevent the permanent magnetic block 54 from rotating inside the cylinder body 51 and improve the stability of the up and down movement of the permanent magnetic block 54.

[0035] The rotating mechanism 6 is arranged on the lower surface of the support plate 3, and the bottom of the rotating mechanism 6 is connected with the top of the electromagnetic lifting mechanism 5. The rotating mechanism 6 includes a first motor 61 fixedly arranged on the lower surface of the support plate 3. The output end of the first motor 61 is fixedly provided with a rotating shaft 62. The lower end of the rotating shaft 62 is fixedly connected with the top of the cylinder body 51. A fixed rod 63 is fixedly arranged on the rod wall of the support rod 2. An electromagnetic brake 64 is fixedly arranged at one end of the fixed rod 63 away from the support rod 2. When the electromagnetic brake 64 is powered on, the brake pads inside the electromagnetic brake 64 will contact and lock the rotating shaft 62 under the action of electromagnetic force. When the electromagnetic brake 64 is powered off, the brake pads inside the electromagnetic brake 64 will separate from the rotating shaft 62. Then, starting the first motor 61 can drive the rotating shaft 62, the weighing hook 4 and the magnetic lifting mechanism to rotate 360° together and then reset. This process is completed through programming design inside the PLC controller 10.

[0036] The mounting bracket 7 is fixedly arranged on the rod wall of the support rod 2. A label recognition mechanism 8 is arranged on the side wall of the mounting bracket 7. The label recognition mechanism 8 includes a mounting plate 81 fixedly arranged on the side wall of the mounting bracket 7. An RFID label reader 82 is fixedly arranged on the side of the mounting plate 81, and the RFID label reader 82 is located on the lower side of the weighing hook 4. The RFID label reader 82 can quickly scan the drug information label on the side wall of the medicine bottle (when medical staff configure drugs, stick the drug label with an RFID chip on the medicine bottle), so as to realize the accurate matching and verification of drug and patient information.

[0037] An automatic speed reduction mechanism 9 is arranged on the side wall of the mounting frame 7. The inside of the automatic speed reduction mechanism 9 is used to pass through the infusion tube and can reduce the infusion speed. The automatic speed reduction mechanism 9 includes a box body 91 fixedly arranged on the side wall of the mounting frame 7. Through openings 92 are provided at both the top and the bottom of the box body 91. Two moving plates 93 are symmetrically arranged inside the box body 91. A slide bar 94 that is horizontally fixed inside the box body 91 and is slidably connected to the two moving plates 93 is provided. Clamping plates 95 are fixedly arranged on one side of the two moving plates 93 facing each other. A second motor 96 is fixedly arranged on the inner side wall of the box body 91. A gear 97 is fixedly arranged on the output shaft of the second motor 96. A rack 98 is meshed with both the upper and lower sides of the gear 97. One end of each of the two racks 98 is fixedly connected to the side surface of one of the two moving plates 93. After the second motor 96 starts to operate, its output shaft drives the gear 97 to rotate. By virtue of the meshing relationship with the rack 98, the gear 97 synchronously pushes the two racks 98 to move towards each other. The movement of the racks 98 drives the two moving plates 93 connected thereto to relatively approach. The moving plates 93 further push the two clamping plates 95 to gradually approach the infusion tube, so that the infusion speed is automatically reduced; arc-shaped openings are provided on one side of the two clamping plates 95 facing each other, and heat conducting plates 99 are fixedly arranged inside the arc-shaped openings. The two clamping plates 95 both adopt a hollow structure, and heating blocks 910 are fixedly arranged inside the two clamping plates 95. By starting the heating blocks 910, the gas inside the clamping plates 95 can be quickly heated. The generated heat is quickly and evenly transferred to the tube wall of the infusion tube through the heat conducting plates 99 with high heat conductivity, and then the pharmaceutical liquid flowing inside the tube is heated.

[0038] A PLC controller 10 is fixedly arranged on the rod wall of the support rod 2. The weighing hook 4, the electromagnetic lifting mechanism 5, the rotating mechanism 6, the label recognition mechanism 8, and the automatic speed reduction mechanism 9 are all electrically connected to the PLC controller 10.

[0039] The operating principle of the present invention is described as follows: medical staff complete the preparation of the liquid medicine according to the specific condition of the neurosurgical patient. Subsequently, a medicine label with an RFID chip is flatly attached to the side wall of the medicine bottle. The chip stores rich medicine information, including key data such as medicine name, specification, dosage form, production batch number, expiration date, dosage, etc. Some chips are also associated with the patient identity information and medication order (the medicine label can be recycled and the medicine information can be re-entered for continued use). After the liquid medicine is prepared, the medical staff turn on the power of the device and stably hang the medicine bottle on the weighing hook 4. The gravity of the medicine bottle is transmitted to the weighing sensor 55 through the weighing hook 4, triggering the sensor to weigh the weighing hook 4 and the medicine bottle. When the weighing sensor 55 detects the medicine bottle hanging signal, it immediately feeds back an electrical signal to the PLC controller 10. After receiving the signal, the PLC controller 10 quickly starts the RFID label reader 82, which can quickly scan the medicine information label on the side wall of the medicine bottle. The internal radio frequency transmitting circuit of the RFID label reader 82 generates a radio frequency signal with a specific frequency and radiates it into the surrounding space through the antenna. When the medicine label with an RFID chip enters the radiation range of the antenna of the RFID label reader 82, the label antenna senses the radio frequency signal, converts it into electrical energy to power the chip, activates the chip, and the chip then modulates the stored data onto the high-frequency carrier signal in ways such as ASK, FSK or PSK, and then sends the reflected signal in a backscattering manner through the label antenna. The antenna of the RFID label reader 82 receives the reflected signal, amplifies and filters it through the radio frequency receiving circuit, demodulates and restores the data, and finally, the data is transmitted to the microprocessor and decoded into readable medicine information. If the medicine label on the medicine bottle is not in the correct position relative to the RFID label reader 82 and the RFID label reader 82 cannot scan the medicine information label on the side wall of the medicine bottle (for 3 seconds continuously), the PLC controller 10 will immediately start the first motor 61 and cut off the power supply of the electromagnetic brake 64. After the power is cut off, the electromagnetic brake 64 releases the locking of the rotating shaft 62, enabling the first motor 61 to drive the rotating shaft 62, the weighing hook 4 and the magnetic elevation mechanism to rotate 360° and then reset, and at the same time, driving the medicine bottle to rotate 360° and then reset (by programming and designing in the PLC controller 10 to control the first motor 61 to rotate 360°, and then rotate 360° in the reverse direction. The first motor 61 is a reduction motor, which can drive the medicine bottle to rotate slowly without causing violent shaking of the medicine bottle, improving the accuracy of the RFID label reader 82 in identifying the medicine label). After resetting, the PLC controller 10 automatically turns on the power supply of the electromagnetic brake 64 through the control circuit, enabling the rotating shaft 62 to be locked and increasing the stability of the medicine bottle hanging. During the rotation, it can ensure that the RFID label reader 82 accurately reads the medicine label. The RFID label reader 82 then feeds back the read information to the PLC controller 10. By comparing it with the patient information preset in the PLC controller 10 system, if the information does not match successfully,The alarm built into the PLC controller 10 will run automatically to alert medical staff that the medicine does not match the patient, and verification and adjustment are required, thus achieving accurate matching and verification of medicine and patient information, greatly reducing the incidence of medication errors, and significantly improving the safety and work efficiency of medical services;

[0040] When the medicine information and the information of the neurosurgery patient are successfully matched automatically by the system and confirmed to be correct, the medical staff first pass the infusion tube through the tube insertion openings 92 at the top and bottom of the box body 91 in sequence. Subsequently, one end of the infusion tube is accurately inserted into the medicine bottle interface to ensure a tight connection. At the same time, the medical staff disinfect the venipuncture site of the patient, and accurately insert the other end of the infusion tube into the patient's vein. After completing the above operations, the medical staff adjust the initial infusion speed by operating the infusion speed regulator on the infusion tube according to the patient's condition, physique, and drug characteristics;

[0041] During the infusion process, as the liquid medicine in the medicine bottle continues to be infused into the patient's body, the liquid level in the bottle gradually decreases. At this time, the value detected by the weighing sensor 55 connected to the weighing hook 4 also decreases synchronously. The weighing sensor 55 transmits the real-time detected weight value to the PLC controller 10 (the gravity of the medicine bottle, infusion tube, and weighing hook 4 all act on the weighing sensor 55). After receiving the feedback signal, the PLC controller 10 quickly and accurately regulates the power supply to the electromagnet 52 through the control circuit, so that the current inside the electromagnet 52 gradually increases. As the current increases, the magnetic adsorption force of the electromagnet 52 on the permanent magnet 54 gradually increases. Under the action of the adsorption force, the permanent magnet 54, weighing sensor 55, and weighing hook 4 overcome the elastic force of the spring 53 and slowly move upward, thereby driving the medicine bottle to rise, compensating for the decrease in the infusion speed caused by the decrease in the liquid level in the bottle (when the liquid level in the medicine bottle decreases, it means that the weight of the medicine decreases, resulting in a decrease in the infusion speed, and the height of the medicine bottle from the ground is increased to make up for it), ensuring that neurosurgery patients can always receive infusion treatment at a stable speed. Taking a 250 mL glass infusion bottle as an example, when the liquid level in the bottle drops by 5 cm due to the consumption of the liquid medicine, the system starts the adjustment mechanism, and the medicine bottle is lifted upward by 3 cm (since the liquid level drops slowly, the medicine bottle also rises slowly during the upward lift process, and it will not affect the infusion effect), which can better maintain the stability of the infusion speed. Through such dynamic adjustment, the potential risks brought to neurosurgery patients by the fluctuation of the infusion speed are effectively reduced (when the medicine bottle is lifted upward, it will pull up a part of the infusion tube, but the common infusion tube usually has enough length when infusing the patient, leaving enough space for the patient's hand, and the height that the medicine bottle is lifted upward does not exceed 6 cm, and this distance will not pull the infusion needle of the infusion tube);

[0042] When the weight of the liquid medicine in the medicine bottle gradually decreases and reaches the threshold preset inside the PLC controller 10, the PLC controller 10 will quickly issue an instruction (at the same time, the PLC controller 10 cuts off the power supply to the solenoid magnet 52 through the control circuit, so that the permanent magnet block 54 and the weighing sensor 55 move down to the bottom of the cylinder body 51 under the action of gravity and the elastic force of the spring 53, and the height of the medicine bottle returns to the initial position for reuse). Then, the second motor 96 is started. After the second motor 96 starts running, its output shaft drives the gear 97 to rotate. By virtue of the meshing relationship with the rack 98, the gear 97 synchronously pushes the two racks 98 to move towards each other. The movement of the rack 98 drives the two moving plates 93 connected thereto to move relatively closer. The moving plates 93 then push the two clamping plates 95 gradually closer to the infusion tube. When the clamping plates 95 apply an appropriate external force to the infusion tube, the inner diameter of the infusion tube becomes smaller and the infusion speed automatically decreases (10 drops per minute), effectively avoiding the entry of air into the infusion tube after the liquid medicine in the medicine bottle is emptied, reducing the risk of air embolism, and preventing damage to the fragile physiological functions of neurosurgical patients due to out-of-control infusion speed, thus improving the safety and stability of the infusion process;

[0043] In cold seasons, the low infusion temperature will cause discomfort to patients. The medical staff operate the PLC controller 10 to issue an instruction through the PLC controller 10 to control the rotation of the second motor 96. The operation of the second motor 96 drives the gear 97 and the two racks 98 to move, so that the two clamping plates 95 gently wrap around the tube wall of the infusion tube. During this process, the clamping plates 95 will not cause extrusion deformation to the tube wall of the infusion tube, ensuring the smoothness of the infusion (the medical staff can judge whether the infusion tube is extruded by observation, and the two clamping plates 95 are in sliding contact with the infusion tube, which can ensure the upward lifting action of the medicine bottle. After the two clamping plates 95 wrap around the tube wall of the infusion tube, the medical staff can pull the infusion tube upward by hand to judge whether the infusion tube is completely clamped). Subsequently, the medical staff operate the PLC controller 10 again to start the heating block 910. After the heating block 910 is powered on, it quickly heats the gas inside the clamping plates 95. The generated heat is quickly and evenly transferred to the tube wall of the infusion tube through the highly thermally conductive heat conducting plate 99, and then heats the liquid medicine flowing in the tube, so that the infusion temperature can be effectively increased. This not only greatly improves the comfort of neurosurgical patients during infusion, but also avoids adverse reactions such as vasospasm caused by the input of low-temperature liquid, creating a safer and more comfortable treatment experience for patients.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
