Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a non-gravity portable speed-controlled infusion device. Background Art

[0002] A disposable infusion set is generally composed of an intravenous needle, an infusion hose, a drug filter, a flow rate regulator, a drip pot, a bottle stopper puncture device, an air filter, etc. When in use, insert the bottle stopper puncture device into the infusion bag, hang the infusion bag on the infusion pole, drain the drug to about 1 / 2 of the drip pot, empty the gas in the infusion hose, close the regulator, and after successfully puncturing the vein, connect the infusion set, adjust the appropriate drip rate, and use gravity to inject the drug into the patient's body.

[0003] Traditional infusion devices have defects such as limited patient activities and the need for special personnel to accompany patients to hold liquids when going out for examinations or surgeries. For example, a non-gravity portable constant-rate infusion device with authorization announcement number CN208481807U solves the problem of traditional infusion devices relying on gravity for infusion.

[0004] Existing non-gravity infusion devices compress the infusion tube by alternating displacement of the infusion tube, causing the liquid to displace forward, thereby delivering the drug solution to the patient at a constant speed. However, in clinical practice, patients have different requirements for the dosage, speed, and tolerance of drug infusion due to different severity of their condition, age, weight, and heart function. Infants, elderly patients, and patients with light weight have relatively weak drug metabolism. If the infusion speed is too fast, it will increase the burden on the heart. Elderly patients and critically ill patients have more comorbidities and multiple organ functions are affected. Even for the same patient, the drug infusion speed requirements are completely different as vital signs change at different stages of the disease. Therefore, it is necessary to accurately control the infusion speed according to the changes in the patient's condition and age and weight to ensure that the patient receives accurate and safe fluid therapy.

[0005] In addition, when the patient has an allergic reaction to the infused medicine or the circulatory load is excessive due to excessive infusion speed, the patient will experience symptoms such as rapid heart rate, rapid breathing, rash, nausea, vomiting, difficulty breathing, sweating, etc. If these symptoms are not discovered in time and the infusion of the medicine is not stopped immediately, it will pose a great threat to the patient's life.

[0006] Therefore, a non-gravity portable rate-controlled infusion device is proposed to solve the above problems. Summary of the invention

When the liquid medicine in the infusion bag 2 is almost used up, an alarm can be sounded to remind medical staff to change the medicine in time.

[0039] The operating principle of the present invention is now described as follows: pull the pull rod 14, the pull rod 14 drives the positioning plate 11 to move, so that the positioning plate 11 and the pin 12 move to the right together, then insert the fixing part 9 into the clamping frame 52, and then press the pull rod 14, the pull rod 14 drives the positioning plate 11 and the pin 12 to be inserted into the fixing part 9 together, and the infusion bag 2 is fixed, and then the slot 8 and the sliding groove 6 are inserted into the clamping frame 52 into the conical seat 51, so that the infusion bag 2 and the conical seat 51 can be relatively fixed, and then the rotating rod 362 and the age indication plate 41 are rotated according to the patient's age, so that the pointer plate 43 is aligned with the age indication area 42 on the age indication plate 41. At this time, the rotating rod 362 drives the conductive rod 37 to contact the corresponding resistor block 40, and then the medical staff will sense The induction ring 281 is sleeved on the outside of the patient's arm where no needle is inserted, and then the small electric push rod 33 is controlled to work through an external switch. The small electric push rod 33 drives the piston plate 34 to move upward, and the gas in the air inlet cylinder 32 is transported to the induction ring 281, and then transported to the air bag ring 282 through the air outlet 30, so that the air bag ring 282 expands and contacts the patient's arm. The air bag ring 282 drives the heart rate sensing module 29 to contact the patient's arm (the heart rate sensing module 29 is an existing mature technology, and the working principle does not need to be repeated in the text). When the air bag ring 282 contacts the patient's arm, the air pressure in the air bag ring 282, the air inlet pipe 31 and the induction ring 281 increases. When the air pressure sensor 35 detects that the air pressure in the air inlet pipe 31 increases to the set value When the pressure reaches a certain level, the air pressure sensor 35 will control the small electric push rod 33 to stop working through the PLC controller. At this time, the piston plate 34 will drive the power block 39 to move upward to a certain position. When the patient is fat, the patient's arm will be relatively thick. The piston plate 34 only needs to drive the power block 39 to move upward a short distance before it stops moving. At this time, the power block 39 will contact the resistor plate 38 near the bottom. The resistance of the resistor plate 38 connected to the circuit is small. The power block 39 is electrically connected to the external power supply. The lower end of the resistor plate 38 is in contact with the conductive rod 37. When the power block 39 is in contact with the resistor plate 38, the current will be transmitted to the conductive block 26, and the conductive block 26 will contact the resistor block 40 in the area corresponding to the patient's age. The resistor block 40 is electrically connected to the micro motor 21 through an external button. When the medical staff presses the external button, the circuit between the resistor block 40 and the micro motor 21 is connected, so that the external current is transmitted to the micro motor 21 to make the micro motor 21 work (the resistance value of the resistor block 40 corresponding to the patient's age gradually decreases from 16 to 35 years old, and the resistance value of the resistor block 40 increases from 36 to 70 years old, and according to the obesity of the patients in an age group, the resistance value of the patients is further fine-tuned, so that the infusion speed of the patients in an age group is slightly different. The infusion speed of obese patients in the same age group is faster than that of thin patients). The micro motor 21 drives the threaded rod 202 to rotate.The threaded barrel 22 is driven to move through the threaded cooperation, and the threaded barrel 22 drives the guide frame 24 and the squeezing roller 25 to move downward at a certain speed through the guide plate 23, so that the infusion bag 2 can be squeezed, so that the medicine in the infusion bag 2 is delivered to the patient's body at a certain speed (the medicine in the infusion bag 2 cannot be an irritating medicine, and will not stimulate the patient's blood vessels and gastrointestinal function). In the process of the threaded barrel 22 driving the squeezing roller 25 to move downward, the conductive block 26 will be driven to move downward together. When the medicine in the infusion bag 2 is almost used up, the conductive block 26 will contact the electric contact block 47, and the conductive block 26 is electrically connected to the external power supply, and the electric contact block 47 is electrically connected to the buzzer 48. When the conductive block 26 and the electric contact block 47 are in contact, the external current will be transmitted to the buzzer 48, so that the buzzer 48 will work, reminding the medical staff that the next bag of medicine needs to be prepared. When the medicine in the infusion bag 2 is used up, the conductive block 26 will contact the conductive plate 27, and the conductive plate 27 is electrically connected to the micro electric push rod 152 through the PLC controller. When the conductive block 26 and the conductive plate 27 are in contact, the micro electric push rod 152 will be controlled by the PLC controller to work. The micro electric push rod 152 drives the squeezing plate 16 to move in the direction close to the infusion tube 4. The infusion tube 4 is blocked by squeezing between the squeezing plate 16 and the squeezing block 17. When the medical staff replaces the infusion bag 2 later, the infusion tube 4 is pulled out from the previous infusion bag 2 and inserted into the next infusion bag 2 to avoid the patient's blood returning. When the patient is allergic to the drug, the patient's heart rate will rise rapidly. When the heart rate sensing module 29 detects that the patient's heart rate rises rapidly, the heart rate sensing module 29 will control the micro electric push rod 152 to work through the PLC controller to block the infusion tube 4, and the PLC controller will control the buzzer 48 to work all the time and emit a sound different from the sound of the drug running out, reminding the medical staff to check the situation as soon as possible.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
