Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a portable peritoneal dialysis catheter function monitoring and alarm device. Background Technology

[0002] Peritoneal dialysis is a treatment technique that uses the peritoneum as a semipermeable membrane and the abdominal cavity as an exchange space to remove excess water, metabolic products and toxins from the body through diffusion and convection, thereby purifying the blood and replacing kidney function.

[0003] There are many causes of catheter drainage obstruction, such as constipation, catheter displacement, fibrin or blood clot blockage, and omentum entrapment. The main manifestation is a slowed or blocked inflow / outflow of drainage fluid. Many patients and healthcare workers are unable to recognize the decline in catheter flow in the early stages due to a lack of objective data. Elderly patients often have poor eyesight, making small amounts of fibrin or blood clots difficult to spot visually. Timing the flow themselves is both inconvenient and inaccurate. Patients often only seek medical attention when the obstruction becomes severe or complete, leading to many peritoneal dialysis catheter failures, increased patient burden, and negatively impacted prognosis.

[0016] Beneficial effects:

[0017] This utility model provides a portable peritoneal dialysis catheter function monitoring and alarm device. When it is necessary to monitor the flow rate and turbidity within the peritoneal dialysis catheter, the patient holds the clamping area of ​​the clamping device onto the catheter. The flow rate sensor and turbidity sensor in the clamping area monitor the flow rate and turbidity of the peritoneal dialysis catheter. The flow rate sensor is an ultrasonic flow meter, which can measure the flow rate through the tubing. The turbidity sensor is photoelectric; since the peritoneal dialysis catheter is a transparent tube, light can pass through, thus measuring turbidity. When the flow rate or turbidity of the peritoneal dialysis catheter exceeds a pre-set threshold, an alarm will be triggered. The signal is transmitted to the buzzer, which sounds an alarm. Simultaneously, an indicator light will also sound an alarm if the peritoneal dialysis catheter flow rate is abnormal. If the buzzer alone sounds an alarm, it indicates a turbidity problem. If both the buzzer and indicator light illuminate simultaneously, it indicates a problem with either the flow rate alone or both flow rate and turbidity, promptly alerting medical staff to address the situation. This clamping device is small and easy to use; the patient can simply hold the peritoneal dialysis catheter for monitoring. It also provides timely alarms for abnormal conditions, alerting medical staff and preventing medical accidents caused by abnormal peritoneal dialysis flow rate and turbidity.

[0028] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the protection scope of this utility model.

[0029] Furthermore, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intervening component present.

[0030] Please see Figure 1-2 This embodiment provides a portable peritoneal dialysis catheter function monitoring and alarm device, which includes: a clamping component 1; a monitoring component 2, which includes a flow rate sensor 21 and a turbidity sensor 22, the sensing ends of the flow rate sensor 21 and the turbidity sensor 22 being disposed in the clamping area 15 of the clamping component 1; and an alarm component 3, which includes an indicator light 31 and a buzzer 32, the flow rate sensor 21 being signal-connected to the indicator light 31, and both the flow rate sensor 21 and the turbidity sensor 22 being signal-connected to the buzzer 32.

[0031] Specifically, when monitoring the flow rate and turbidity within the peritoneal dialysis catheter is required, the patient holds the clamp 1 and clamps the clamping area 15 of the clamp 1 onto the peritoneal dialysis catheter. The flow rate sensor 21 and turbidity sensor 22 in the clamping area 15 monitor the flow rate and turbidity of the peritoneal dialysis catheter. The flow rate sensor 21 is an ultrasonic flow meter that can measure the flow rate through the tubing. The turbidity sensor 22 is photoelectric; since the peritoneal dialysis catheter is a transparent tube, light can pass through, thus measuring the turbidity. When the flow rate or turbidity of the peritoneal dialysis catheter exceeds a pre-set threshold, a signal is transmitted to the buzzer 32. The buzzer 32 sounds an alarm, and the indicator light 31 also sounds an alarm when the peritoneal dialysis catheter flow rate is abnormal. If the buzzer 32 sounds alone, it indicates a turbidity problem. If the buzzer 32 and the indicator light 31 light up at the same time, it indicates a problem with either the flow rate alone or both the flow rate and turbidity. This promptly alerts medical staff to address the situation. The clamp 1 is small in size, easy to carry, and convenient to use. The patient can hold the peritoneal dialysis catheter for monitoring. At the same time, it can promptly alarm for abnormal conditions, alerting medical staff and preventing medical accidents caused by abnormal peritoneal dialysis flow rate and turbidity.

[0032] In some possible embodiments, the clamping member 1 includes a left clamping rod 11, a right clamping rod 12, a shaft 13, and a clamping spring 14. The shaft 13 is rotatably connected to the left clamping rod 11 and the right clamping rod 12, respectively. The clamping spring 14 is sleeved on the shaft 13, and the two ends of the clamping spring 14 abut against the left clamping rod 11 and the right clamping rod 12, respectively. The front part of the left clamping rod 11 and the right clamping rod 12 that are in contact with each other is the clamping area 15. The rear part of the left clamping rod 11 is the left holding part 111, and the rear part of the right clamping rod 12 is the right holding part 121.

[0033] Specifically, the left clamp 11 and the right clamp 12 are connected together by a shaft 13 that rotates together. The clamping spring 14 supports the rear sections of the left clamp 11 and the right clamp 12. The shaft 13 acts as the fulcrum for the left clamp 11 and the right clamp 12. The front sections of the left clamp 11 and the right clamp 12 are clamped to form a clamping area 15. When needed, the patient pinches the left holding part 111 and the right holding part 121 of the left clamp 11 and the right holding part 121 to close them together. The clamping area 15 opens at the same time. The peritoneal dialysis catheter is then placed into the clamping area 15 and the patient releases their hand to complete the clamping.

[0034] In some possible implementations, the clamping area 15 has a pre-reserved arc-shaped groove 151, and the sensing ends of the flow rate sensor 21 and the turbidity sensor 22 are respectively arranged on both sides of the arc-shaped groove 151. An arc-shaped rubber pad 16 is provided on one side of the front section of the left clamping rod 11 and the right clamping rod 12, and a groove adapted to the peritoneal dialysis catheter is provided between the two arc-shaped rubber pads 16.

[0035] Specifically, the peritoneal dialysis catheter is a flexible tube. If the clamping area 15 clamps too tightly, it will deform the catheter, leading to blockage or slowing the flow rate. The arc-shaped groove 151 of the clamping area 15 provides space for the peritoneal dialysis catheter, preventing the sensing ends of the flow rate sensor 21 and turbidity sensor 22 from clamping the catheter too tightly. Two arc-shaped rubber pads 16 at the edge of the clamping area 15 further clamp the peritoneal dialysis catheter. The rubber material and the grooves adapted to the peritoneal dialysis catheter also serve to prevent deformation of the catheter.

[0036] In some possible implementations, both indicator light 31 and buzzer 32 are mounted on the side of the left holding part 111. A storage battery is installed inside the left holding part 111, and both the buzzer 32 and indicator light 31 are electrically connected to the storage battery. Both the flow rate sensor 21 and the turbidity sensor 22 are electrically connected to the storage battery. A charging interface 4 is mounted on the side of the left holding part 111 and is electrically connected to the storage battery.

[0037] Specifically, the indicator light 31 and buzzer 32 are located on the side of the left holding part 111, which will not affect the patient's handhold, and at the same time, the indication is obvious and the signal is easier to receive; the battery in the left holding part 111 provides power to the buzzer 32, indicator light 31, flow rate sensor 21 and turbidity sensor 22, without the need for an external power supply, increasing the portability of the device, and the charging port 4 charges the battery; the right holding part 121 facilitates the patient's control of the two sensors and makes it easy to open the sensors when using them.

[0038] In some possible implementations, both the left clamp 11 and the right clamp 12 are made of plastic.

[0039] Specifically, the plastic material is lighter and easier for patients to hold.

[0040] In some possible implementations, both the flow rate sensor 21 and the turbidity sensor 22 are connected to the terminal signal.

[0041] Specifically, the flow rate sensor 21 and the turbidity sensor 22 are connected to the nurse station terminal or mobile terminal. The nurse station terminal or mobile terminal can record the flow rate and turbidity of the fluid in the peritoneal dialysis catheter for each dialysis session, which is convenient for medical staff to assess the patient's condition.

[0042] In some possible implementations, indicator light 31 is a single-lamp tri-color signal light.

[0043] Specifically, the single-lamp three-color indicator light has three colors: green, yellow, and red. Two thresholds can be set for the flow rate of the flow rate sensor 21. Under normal circumstances, the single-lamp three-color indicator light is green. The first threshold is when the flow rate is relatively fast, and the single-lamp three-color indicator light flashes a yellow signal. The second threshold is when the flow rate is too fast, and the single-lamp three-color indicator light flashes a red signal. Medical staff can more intuitively observe the flow rate of the fluid in the patient's peritoneal dialysis catheter.
