Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent detection device for regularly detecting the change in the amount of a drug solution in a chemotherapy pump. Background Art

[0002] Chemotherapy is the abbreviation of chemical drug therapy, which achieves the purpose of treatment by using chemotherapeutic drugs to kill cancer cells. Chemotherapy is one of the most effective means of treating cancer at present. It is one of the three major treatments for cancer together with surgery and radiotherapy. Chemotherapy is a systemic treatment method. No matter what route is used for administration, chemotherapy drugs will be distributed throughout the body's organs and tissues through blood circulation. Therefore, for some patients who are not convenient for surgery, chemotherapy is the main treatment method.

[0003] When medical staff perform chemotherapy on patients, they will inject the liquid medicine used to treat patients into the chemotherapy pump used for chemotherapy, and then connect it to the PICC or PORT or indwelling needle on the patient's hand through the catheter, and put the white sensing device at the connection close to the patient's skin, so that the liquid medicine in the bottle enters the body by temperature sensing. The liquid medicine in the chemotherapy pump will be added to the latex bag wrapped on the outside through the injection rod, so that the soft plastic bag will expand. As the liquid medicine is injected, the outer diameter of the expanded latex bag will slowly decrease until it is finally wrapped on the outside of the injection rod again. The chemotherapy pump is usually about 240ml and needs to be maintained for 46 hours, which means that only 5ml of medicine is injected into the patient's body every hour. Therefore, it is difficult for medical staff to observe with the naked eye that the expanded soft plastic bag has shrunk compared to the previous time period.

[0004] When patients receive chemotherapy in the hospital, medical staff will observe the changes in the soft plastic bag before handing over, and make relevant records. Since most medical staff work in three shifts, that is, they change shifts every 8 hours, the changes in the soft plastic bag are large, so medical staff can still see it with the naked eye. However, many patients will take the chemotherapy pump home and carry out relevant chemotherapy at home. The liquid medicine in the chemotherapy pump is injected into the patient's body within 2 days. After the chemotherapy pump is free of medicine, the patient returns to the hospital and the medical staff unplugs it. During the chemotherapy at home, it is difficult for the patient to carefully observe the changes in the soft plastic bag. Sometimes, after carrying it too many times, they will be careless and not observe it. Or the connection is not tightly connected, the clamp clamps the catheter so that the liquid medicine does not change, or the sensor device is not close and the speed is too slow, etc., which will affect the effect of the patient's chemotherapy, and it is impossible for medical staff and patients to discover and deal with it, which brings great inconvenience to the patient's chemotherapy.

A U-shaped clearance groove for making way for the catheter is opened on one side of the upper cover 120.

[0028] The intelligent detection system 200 is used to periodically detect the change in the maximum outer diameter of the soft plastic bag 320 after expansion in the chemotherapy pump 300. The intelligent detection system 200 is arranged on the transparent box body 100. The intelligent detection system 200 includes an infrared ranging sensor 220 symmetrically arranged on both sides of the transparent box body 100 and located at the maximum outer diameter of the soft plastic bag after expansion, a control module 210, a power module 230 and a display 240 for displaying the change in the outer diameter of the soft plastic bag 320 detected by the infrared ranging sensor 220. The display 240 is arranged on one side of the transparent box body 100, the control module 210 is respectively communicated with the infrared ranging sensor 220 and the display 240, and the power module 230 is respectively electrically connected to the infrared ranging sensor 220, the control module 210 and the display 240.

[0029] The intelligent detection system 200 also includes an alarm module 260 that sends an alarm signal when the infrared ranging sensor 220 detects that the change in the maximum outer diameter of the expanded soft plastic bag 320 is greater than or less than the change range value. The alarm module 260 is communicatively connected to the control module 210.

[0030] The intelligent detection system 200 also includes a pressure sensor 250 for periodically detecting the weight of the drug solution in the chemotherapy pump. The pressure sensor 250 is arranged on a placement seat and is communicatively connected to the control module 210. By effectively combining the pressure sensor 250 with the infrared ranging sensor 220, it is possible to perform dual detection on the change in the amount of drug solution in the chemotherapy pump 300, thereby further improving the detection accuracy of the intelligent detection device.

[0031] The infrared ranging sensor 220 is arranged on both sides of the transparent box body 100 through the height adjustment device 600. The height adjustment device 600 includes a push rod 610, an up and down driving mechanism 620 and a control button. When the operator manually presses the control button once, the up and down driving mechanism 620 drives the push rod 610 to move upward. When the operator presses the control button again, the up and down driving mechanism 620 stops working. When the operator presses the control button for the third time, the up and down driving mechanism 620 drives the push rod 610 to move downward.

[0032] A mounting seat 611 for mounting the infrared ranging sensor 220 is provided at the upper end of the push rod 610, and a fine-tuning device for fine-tuning the upper and lower heights of the infrared ranging sensor 220 is provided on the mounting seat 611. The upper and lower driving mechanism 620 is used to drive the push rod 610 to move up and down. The output shaft of the upper and lower driving mechanism 620 is connected to the lower end of the push rod 610. The control button is used to control the upper and lower driving mechanism to work.

[0033] The intelligent detection device for timed detection of changes in the amount of liquid medicine in a chemotherapy pump is also provided with a shoulder strap 110 which is carried on the patient's shoulders when the patient gets up and exercises. One end of the shoulder strap 110 is arranged on one side of the upper end of the transparent box body 100, and the other end is arranged on the other side of the upper end of the transparent box body 100. This structure is convenient for patients to carry.

[0034] The display 240 displays the time and distance, and is set to measure once every 2 hours. If the change in the maximum outer diameter of the inflated soft plastic bag detected twice is greater than or less than the change range value, the control module 210 controls the alarm module 260 to send an alarm signal, that is, the red alarm light 500 lights up and the alarm bell rings at the same time, to prompt medical staff or patients to take corresponding measures.

[0035] The display 240 can display the time of 6 times at the same time, so that the patient can compare with the previous times. If the amount of liquid medicine has not changed, the patient can check in time or contact the medical staff for adjustment.

[0036] The specific operation of the present invention is as follows:

[0037] The medical staff connects the chemotherapy pump to the infusion needle on the patient, secures it properly, then opens the upper cover on the transparent box, puts the chemotherapy pump in steadily, and then closes the upper cover to secure it. Then press the start button 400 to control the intelligent detection system to work. The infrared distance sensor measures the maximum outer diameter of the soft plastic bag after internal expansion and displays it on the display. The system is set to automatically measure every 2 hours, and no other operation is required. When the patient is observed at home, he can observe the distance number on the screen every 2 hours to see if there is any change. When the change in the maximum outer diameter of the soft plastic bag after expansion is greater than or less than the change range value, the control module will control the alarm module to send an alarm signal to prompt the medical staff or the patient to carry out follow-up treatment in time.

[0038] In summary, the present invention includes an intelligent detection system for regularly detecting the change in the maximum outer diameter of the soft plastic bag after expansion in the chemotherapy pump. The intelligent detection system can regularly detect the amount of liquid medicine in the chemotherapy pump to ensure that the chemotherapy liquid used to treat the patient can be smoothly input into the patient's body within the specified time, which brings great convenience to the patient's chemotherapy work.
