Description

Renal dialysis patient bleeding detection warning device

The invention relates to a hemorrhage detection and warning device for a renal dialysis patient, and more particularly to a hemorrhage detection and warning device for a renal dialysis patient for detecting whether blood leakage occurs in the injection area of the patient.

The kidney (Kidney) is an organ in the vertebrate body, which is part of the urinary system. It is responsible for filtering impurities in the blood, maintaining the balance of body fluids and electrolytes, and finally producing urine to be discharged from the body through subsequent channels. The kidney also has endocrine functions to regulate blood pressure.

Physiologically, the kidney mainly affects blood flow, blood composition, blood pressure regulation, bone development, and has some important metabolic functions. Therefore, if there are related diseases, it can cause abnormal development, edema or dehydration, damage to the immune system, and even Cause death.

Renal failure refers to the failure of the kidney to effectively remove impurities in the blood caused by kidney problems caused by kidney disease, which in turn affects the body's metabolism, and can be fatal in severe cases.

The two main causes of renal failure are acute kidney injury and chronic kidney disease. Acute kidney injury can be cured under normal conditions with proper treatment, while chronic kidney disease is usually irreversible.

When there is a problem with the kidneys and the impurities in the blood cannot be eliminated, it is necessary to eliminate the impurities in the blood by "dialysis", which is currently commonly used The methods are hemodialysis and peritoneal dialysis.

Hemodialysis is a treatment method that uses a hemodialysis machine to extract the patient's blood out of the body, filter waste and excess water from it, and then send clean blood back to the body. Generally, patients need to go to a hospital or a professional dialysis center, and the nursing staff will perform the dialysis work, and the schedule is less flexible. The use of hemodialysis to remove impurities from the blood must be performed three times a week to maintain the health of the patient's blood.

The peritoneal dialysis method does not need to draw blood, but uses the patient's peritoneum as a medium, injects dialysate to absorb excess water and waste in the body, and then discharges them out of the body. Peritoneal dialysis can be performed by the patient or caregiver at home or a place suitable for dialysis after the guidance of medical personnel. The use of peritoneal dialysis to exclude impurities in the blood must be performed three times a day to maintain the health of the patient's blood. Compared with hemodialysis, the time elasticity of peritoneal dialysis is higher, and it will not damage the patient's residual renal function.

Both hemodialysis and peritoneal dialysis must invade the patient's body with a pinhole or fistula, so there is a risk of blood leakage during dialysis, that is, the patient's blood will leak from the outside of the pinhole or fistula Or the missed detection caused a large amount of blood to flow from the wound. If the patient is taking anticoagulant drugs, it may cause a large amount of blood loss because the wound cannot be coagulated, especially using peritoneal dialysis can be performed at home. When a large amount of blood loss occurs It is safe to have no medical staff to assist the patient. In addition, no matter whether the hemodialysis method or the peritoneal dialysis method draws blood from the patient's body to the kidney dialysis machine for filtering treatment, and then drains back to the body, If bleeding or leakage occurs during this process, and the nurse does not If found, it can lead to coma due to a large amount of blood leakage, and eventually loss of life.

Human body bleeding is difficult to avoid due to needle insertion, but blood flow will not only cause danger to life after needle insertion. Refer to Figure 1. Taiwan Patent I569845, a needle removal and blood leakage detection device, including a sensor with a flexible sensor. A component 11 and a warning device 12 for mounting the sensing component 11. The flexible sensor 11 is provided with two blood leakage sensing electrodes for surrounding the needle puncture area of the patient's arm. The two blood leakage sensing electrodes can be bridged by a needle to be short-circuited, or exposed by the needle puncture area. The blood contact is turned on and short-circuited. The warning device 12 is similar to a wristwatch and can be installed on the patient's wrist, can be electrically connected to the two blood leakage sensing electrodes, and sends a warning message when the two blood leakage sensing electrodes are short-circuited.

It can be known from the above description that although the conventional method discloses the warning device for needle removal and blood leakage detection, so as to avoid the situation of continuous blood loss, there are still the following disadvantages in actual use:

First, the procedure is tedious and difficult to set up: the scratch sensor must be attached to the patient's injection area before the needle sticking procedure. The alarm device is first attached to the patient's wrist, and then the alarm device and the scratch sensor are performed It is necessary to connect the electric bank before the needle is inserted. For the medical staff, the procedure is complicated and difficult to set.

2. The alarm device is easy to fall off when it is connected to the sensor: The alarm device that is conventionally set on the wrist is connected to the sensor in a straight line. Because the length of the sensor is fixed, you must estimate the appropriate distance in advance to set the sensor. Sensor, and the flex sensor uses a tablet The plugging method of the shaped end portion is apt to cause the warning device to be separated from the flexible sensor due to the muscle movement of the patient's wrist and the plastic restoring force of the flexible sensor itself, thereby losing the warning function.

3. It cannot be installed on other parts of the human body: The conventional leak detection device can only be applied to the arm, and it is not applicable to the detection of leaks in other parts, let alone a dialysis patient using peritoneal dialysis, so the scope of application is affected by limit.

Therefore, how to correctly detect blood leakage and provide it to dialysis patients without affecting the patient and the medical staff can detect the situation of the blood leakage at the first time, and it is convenient for the medical staff to operate and use, is a related technology People urgently need to work towards the goal.

In view of this, an object of the present invention is to provide a hemorrhage detection and warning device for a dialysis patient, which is suitable for covering an injection area, including a covering absorber, two detection modules, a control module, and an alarm. Module.

The two detection modules are spaced from the cover absorber.

The control module is electrically connected to the two detection modules to determine whether the covering absorber absorbs blood.

The alarm module is electrically connected to the control module. When the covering absorber absorbs blood, the alarm module issues an alarm.

When it is not necessary to perform the blood leakage, the switch element 332 turns off the dialysis patient's hemorrhage detection warning device. When the dialysis patient's hemorrhage detection and warning device is turned on, the operation display light 333 displays a green light to indicate that the dialysis patient's hemorrhage detection and warning device has begun to perform a leak. When the dialysis patient's hemorrhage detection and warning device is turned off At this time, the operation display lamp 333 goes out.

The memory element 334 can store basic data of relevant personnel who contact the injection area, such as basic data of nursing operators, patients, and family members of the patients. In the first preferred embodiment, the memory element 334 stores the emergency contact information of the patient (such as a caregiver or family member). When the control module 33 determines that the person has a blood leak, the transmission module is used to notify the emergency The mobile device A carried by the contact person prevents the person (dialysis patient) from coma due to excessive blood loss, and no one comes to the rescue. In addition, the memory element 334 can record the time of the patient's injection. To provide a reference for the patient or medical staff.

The alarm module 34 is electrically connected to the control module 33.
