Description

Technical Field

[0001] The invention relates to the technical field of remote monitoring, and in particular to a peritoneal dialysis fluid exchange error operation alarm management system. Background Art

[0002] Peritoneal dialysis is one of the main treatments for patients with chronic renal failure. Most peritoneal dialysis operations are performed at home. After the hospital completes the operation training for patients, patients return home to perform peritoneal dialysis treatment on their own. Improper operation may cause infection at the dialysis site and lead to complications such as peritonitis, which seriously affects the continuation of peritoneal dialysis treatment.

[0003] Medical staff cannot tell whether home peritoneal dialysis patients can follow standard procedures when they are out of their supervision. Therefore, it is necessary to design a system that can effectively monitor whether the patient's peritoneal dialysis process at home is standardized and provide alarm intervention for incorrect operations or dangerous conditions. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a peritoneal dialysis fluid exchange error operation alarm management system to improve the operation standardization.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A peritoneal dialysis fluid exchange error operation alarm management system, comprising:

[0007] Camera: captures the fluid changing action video of the fluid changing personnel and sends the fluid changing action video to the server in real time;

[0008] Server: Determine the current stage of fluid exchange based on the fluid exchange action video, and determine whether the fluid exchange action is correct based on the current stage of fluid exchange. If the fluid exchange action is wrong, send a fluid exchange action error alarm message and correct operation instructions to the client, and send the number of fluid exchange action errors to the medical terminal;

[0009] Medical and nursing end: Count the number of fluid replacement errors. When the number of fluid replacement errors reaches the threshold, send training request information to the client.

[0010] Client: Receive and display error alarm information, correct operation instructions and training requirements for fluid replacement action.

[0011] Furthermore, the camera is equipped with a multi-color light source with adjustable brightness. When the camera shoots the dialysate, the light source is adjusted to obtain dialysate images under multiple colors and brightnesses. The server obtains the liquid turbidity information and liquid level position information by analyzing the color of the dialysate and the position of the liquid surface edge in multiple dialysate images to determine whether there is dialysis abnormality.

[0012] Furthermore, the server includes an image recognition module and a timing module. The image recognition module recognizes the content of the fluid exchange action video through a contour recognition method and a gesture recognition method to distinguish the current fluid exchange stage. The timing module records the duration of the current fluid exchange stage. When the duration of the same stage is greater than the corresponding threshold, an alarm is issued.

[0013] Furthermore, the current fluid exchange phase includes a preparation phase, a connection phase, a drainage phase, an exhaust phase, a perfusion phase, and a separation phase.

[0014] Furthermore, when the content of the fluid exchange action video is the patient's face and the peritoneal dialysis fluid bag, the current fluid exchange stage is the preparation stage. The server determines whether the fluid exchange action is correct based on whether there is a mask on the patient's face, whether the information on the peritoneal dialysis fluid bag is valid, and whether there is liquid in the peritoneal dialysis fluid bag.

[0015] Furthermore, the content of the fluid exchange action video is when the fluid exchange personnel holds the peritoneal dialysis fluid bag catheter and the patient's peritoneal dialysis catheter, or when the fluid exchange personnel holds the drainage bag catheter and the patient's peritoneal dialysis catheter, the current fluid exchange stage is the connection stage, and the server judges whether the fluid exchange action is correct based on the contact position of the fluid exchange personnel's hand with the peritoneal dialysis fluid bag catheter, the drainage bag catheter or the patient's peritoneal dialysis catheter.

[0016] Furthermore, when the content of the fluid exchange action video is the connection between the drainage bag catheter and the patient's peritoneal dialysis catheter and the peritoneal dialysis bag catheter clamp, the current fluid exchange stage is the drainage stage. The server determines whether the fluid exchange action is correct based on the closure status of the patient's peritoneal dialysis catheter connection and the peritoneal dialysis bag catheter switch status.

[0017] Furthermore, when the content of the fluid exchange action video is the drainage tube, the peritoneal dialysis fluid bag catheter and the patient-end switch, the current fluid exchange stage is the exhaust stage, and the server determines whether the fluid exchange action is correct based on whether the drainage tube and the peritoneal dialysis fluid bag catheter are connected and whether the patient-end switch is closed.

[0018] Furthermore, when the content of the fluid exchange action video is the drainage tube clamp and the peritoneal dialysis catheter, the current fluid exchange stage is the perfusion stage, and the server determines whether the fluid exchange action is correct based on the switch state of the abdominal drainage tube clamp and whether the peritoneal dialysis catheter is connected.

[0019] Furthermore, the content of the fluid exchange action video is when the fluid exchange personnel holds the peritoneal dialysis bag catheter and the iodine cap, the current fluid exchange stage is the separation stage, and the server determines whether the fluid exchange action is correct based on the contact position of the fluid exchange personnel's hand with the peritoneal dialysis bag catheter or the iodine cap.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1) The present invention uses an image recognition method to identify the fluid replacement action according to the camera's shooting content, and sets a judgment basis based on possible erroneous operations related to the action to identify abnormalities in the operation. It can be well applied to patients undergoing home dialysis to provide them with guidance services, improve the professionalism of the operation, and reduce infections or injuries caused by lack of professionalism and hygiene awareness.

[0022] 2) The camera of the present invention is equipped with a multi-color light source with adjustable brightness. It can identify the color, turbidity, liquid level position and other information of the dialysate through the color images of the dialysate under different colors and intensities of light, analyze whether the patient has suffered secondary injuries during the dialysis process, and issue a re-examination alarm in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Example 1

[0026] The present invention is a peritoneal dialysis fluid replacement error operation alarm management system, comprising:

[0027] Camera: captures the fluid changing action video of the fluid changing personnel and sends the fluid changing action video to the server in real time;

[0028] Preferably, the camera has a multi-color light source with adjustable brightness. When the camera shoots the dialysate, the light source is adjusted to obtain dialysate images under multiple colors and multiple brightnesses. The server obtains the liquid turbidity information and liquid level position information by analyzing the color of the dialysate and the position of the liquid surface edge in multiple dialysate images to determine whether there is dialysis abnormality.

[0029] The multi-color light source with adjustable brightness includes red, green, blue, white and other light sources with adjustable brightness. In clinical practice, the common dialysate color is colorless to light yellow (normal state), and there are also dialysates of different colors such as milky white (possible infection), red (intraperitoneal bleeding), and orange (using the drug rifampicin). Most abnormal dialysates are mainly red. After turning off other lights in the room and isolating other light sources, use a multi-color light source with adjustable brightness to illuminate the drainage tube, peritoneal dialysis bag, etc. to see the location of the dialysate. By analyzing the difference between the performance of the dialysate under red light and other colored lights, as well as the difference in transmittance under white light, it is possible to better distinguish the difference between abnormal dialysate and normal dialysate, thereby judging abnormal conditions during the dialysis process and promptly reminding patients to recheck. It can also be used at night to avoid using indoor lights to affect patients' rest.

[0030] Due to the small inner diameter of the drainage tube, the lack of standardization in the setting angle of the camera at home may lead to insufficient clarity of the liquid level boundary line in the video. By illuminating with light sources of different brightness or different colors, the exact position of the liquid level boundary line can be identified from the differences in image brightness and color refractive index.

[0031] Server: Determine the current stage of fluid exchange based on the fluid exchange action video, and determine whether the fluid exchange action is correct based on the current stage of fluid exchange. If the fluid exchange action is wrong, send a fluid exchange action error alarm message and correct operation instructions to the client, and send the number of fluid exchange action errors to the medical terminal;

[0032] The current fluid exchange stage is identified by image recognition, which usually includes a preparation stage, a connection stage, a drainage stage, a venting stage, a perfusion stage, and a separation stage.

[0033] in:

[0034] When the content of the fluid exchange video is the patient's face and the peritoneal dialysis fluid bag, the current fluid exchange stage is the preparation stage. The server determines whether the fluid exchange action is correct based on whether the patient has a mask on his face, whether the information on the peritoneal dialysis fluid bag is valid, and whether there is liquid in the peritoneal dialysis fluid bag. Valid information includes the expiration date on the peritoneal dialysis fluid bag. If there is liquid in the peritoneal dialysis fluid outer packaging bag, it means that the sealing is insufficient.

[0035] The content of the fluid exchange action video is that when the fluid exchange personnel hold the peritoneal dialysis bag catheter and the patient's peritoneal dialysis catheter, the current fluid exchange stage is the connection stage. The server determines whether the fluid exchange action is correct based on the contact position between the fluid exchange personnel's hands and the peritoneal dialysis bag catheter or the patient's peritoneal dialysis catheter. Avoid contamination caused by hand contact with the pipe connection.

[0036] When the content of the fluid exchange video is the connection between the drainage bag catheter and the patient's peritoneal dialysis catheter and the peritoneal dialysis bag catheter clamp, the current fluid exchange stage is the drainage stage. The server determines whether the fluid exchange action is correct based on the closure of the patient's peritoneal dialysis catheter connection and the switch status of the peritoneal dialysis bag catheter. During the drainage stage, it is necessary to ensure that the dialysis fluid does not leak out and does not affect indoor hygiene. The unobstructed drainage tube can ensure the normal discharge of the fluid. A timeout alarm is issued when the drainage stage lasts for more than 30 minutes.

[0037] When the content of the fluid exchange action video is the drainage tube and the peritoneal dialysis fluid bag catheter, the current fluid exchange stage is the exhaust stage. The server determines whether the fluid exchange action is correct based on whether the drainage tube and the peritoneal dialysis fluid bag catheter are connected and the switch on the patient end is turned off.

[0038] When the content of the fluid exchange action video is the drainage tube clamp and the peritoneal dialysis catheter, the current fluid exchange stage is the perfusion stage. The server determines whether the fluid exchange action is correct based on the switch status of the drainage tube clamp and whether the peritoneal dialysis catheter is connected. A timeout alarm is issued when the perfusion stage lasts for more than 15 minutes.

[0039] The content of the fluid exchange action video is that when the fluid exchange personnel holds the peritoneal dialysis bag catheter and the iodine-containing cap, the current fluid exchange stage is the separation stage. The server determines whether the fluid exchange action is correct based on the contact position between the fluid exchange personnel's hand and the peritoneal dialysis bag catheter or the iodine-containing cap.

[0040] Medical and nursing end: Count the number of fluid replacement errors. When the number of fluid replacement errors reaches the threshold, send training request information to the client.

[0041] If there are many errors, it means that the operator's professionalism and health and safety awareness are not up to standard, and it is difficult for him to continue to perform the responsibility of changing fluids for home dialysis. It is necessary to conduct unified training on relevant knowledge, improve operational standardization, or replace operators.

[0042] Client: Receive and display error alarm information, correct operation instructions and training requirements for fluid replacement action.

[0043] The client is used to prompt the patient and related personnel to intervene in the operator's actions and provide timely feedback to avoid infection risks to the patient. When the server detects an error in the fluid exchange action, the client receives and displays the correct operating instructions for easy correction. At the same time, if the number of fluid exchange action error alarms is too high, the client receives training requirement information to notify the operator to come to the hospital for operation training.

[0044] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
