Description

Hemorrhage detection warning device for kidney dialysis patients

The present invention relates to a blood dialysis patient hemorrhage detection warning device, in particular to a kidney dialysis patient hemorrhage detection warning device for detecting whether blood leakage occurs in the injection area of the patient.

Kidney is an organ in the body of vertebrates. It is part of the urinary system. It is responsible for filtering impurities in the blood and maintaining the balance of body fluids and electrolytes. Finally, urine is produced and discharged from the body through subsequent pipelines. At the same time, 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, so if there are related diseases, it can cause abnormal development, edema or dehydration, damage to the immune system, and even Cause death.

Renal failure (renal failure) refers to the failure of the kidney due to kidney disease, which leads to failure to effectively remove impurities in the blood, which in turn affects the metabolism of the body. In severe cases, it can be fatal.

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

When there is a kidney problem and the impurities in the blood cannot be eliminated, the impurities in the blood must be eliminated by "dialysis". Currently, the commonly used methods include hemodialysis and peritoneal dialysis.

Hemodialysis is a treatment method that uses a hemodialysis machine to draw the patient's blood out of the body, filter waste and excess water in it, and then send clean blood back to the body. Generally speaking, patients need to go to a hospital or a professional dialysis center, and nurses perform dialysis work, and the schedule is relatively inflexible. The use of hemodialysis to remove impurities in 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, injecting dialysate to absorb excess water and waste in the body, and then expel them out of the body. Peritoneal dialysis can be operated by the patient or caregiver at home or in a place suitable for dialysis after being directed by medical staff. The use of peritoneal dialysis to remove 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 residual renal function of the patient.

Both hemodialysis and peritoneal dialysis must penetrate the patient's body through a pinhole or fistula, so there is a risk of blood leakage during kidney dialysis, that is, the patient's blood will leak from the outside of the pinhole or fistula Or, the omission of detection leads to a large amount of blood pouring from the wound. If the patient is taking anticoagulant drugs, there may be a risk of a large amount of blood loss due to the wound not being able to coagulate, especially when using peritoneal dialysis can be performed at home. When a large amount of blood loss occurs There is no medical staff to assist the patient's safety. In addition, whether it is hemodialysis or peritoneal dialysis, blood is drawn from the patient to the kidney dialysis machine for filtration, and then drained back to the body. During this process, if bleeding or blood leakage occurs, and the nurse does not find it in the first place, it will lead to the patient's coma due to a large amount of blood leakage, and ultimately the loss of life.

Bleeding is difficult to avoid because of needle sticking, but blood flow will cause danger to life after needle sticking. Refer to Figure 1 for Taiwan patent I569845, a needle removal and blood leakage detection device, including a sensor with a flexible sensor The component 11 and a warning device 12 for installing the sensing component 11. The flexible sensor 11 is provided with two blood-leakage sensing electrodes for surrounding the needle-insertion area of the patient's arm. The two blood-leakage-sensing electrodes can be short-circuited by a needle, or exposed by the needle-insertion area. The blood contacts and conducts short circuit. The warning device 12 can be installed on the patient's wrist like a wristwatch, can be electrically connected to the two blood leakage sensing electrodes, and can issue a warning message when the two blood leakage sensing electrodes are short-circuited.

From the above description, it can be seen that although the conventional disclosure discloses a warning device for needle removal and blood leakage detection, so as to avoid continuous blood loss, the actual use still has the following disadvantages:

1. The procedure is cumbersome and difficult to set up: the flex sensor must be attached to the patient's injection area before the needle insertion procedure, first attach the warning device to the patient's wrist, and then perform the warning device with the flex sensor After the electric bank is connected, the needle insertion operation can be carried out at the end. For medical personnel, the procedure is cumbersome and difficult to set up.

2. The connection between the warning device and the flexible sensor is easy to fall off: the conventional warning device and the flexible sensor are connected in a straight line. Because the length of the flexible sensor is fixed, the appropriate distance must be estimated in advance to set the flexible sensor. Sensor, and the flexible sensor uses a patch-shaped end connection, which is easy to separate the warning device from the flexible sensor due to the patient's wrist muscle activity and the plastic restoring force of the flexible sensor itself. Then lose the warning function.

3. Cannot be installed in other parts of the human body: the conventional blood leakage detection device can only be applied to the arm, and it is not suitable for the detection of blood leakage in other parts, not to mention the kidney dialysis patients using peritoneal dialysis, so the scope of application is subject to limit.

Therefore, how to correctly detect blood leakage and provide it to patients with kidney dialysis without affecting it, so that patients and medical staff can detect the blood leakage at the first time, and at the same time, it is convenient for medical staff to operate and use, which is related technology The goal of the urgent need of personnel.

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

The two detection modules are spaced apart from the covering absorber.

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

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

Another technical means of the present invention is that the above-mentioned kidney dialysis patient hemorrhage detection warning device further includes two assemblies, which are respectively disposed between the two detection modules and the control module, so that the Two detection modules and the control module can be combined separately.

Another technical means of the present invention is that the above two detection modules respectively include a plurality of conductive fibers, and the plurality of conductive fibers are spaced apart from each other.

When the cover absorber 31 is electrically connected to the control module 32 and the cover absorber 31 covers the injection area, the switch element is passed 332 turns on the dialysis patient's hemorrhage detection warning device and executes the blood leakage detection. When it is not necessary to perform the blood leakage detection, the switch 332 turns off the dialysis patient's bleeding detection warning device. When the renal dialysis patient's hemorrhage detection warning device is turned on, the operation display lamp 333 indicates with green light that the renal dialysis patient's hemorrhage detection warning device has started to perform blood leakage, and when the renal dialysis patient's hemorrhage detection warning device is turned off At this time, the operation indicator 333 goes out.

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

The alarm module 34 is electrically connected to the control module 33. When the control module 33 recognizes that the covered absorber 31 absorbs blood, the control module 33 controls the alarm module 34 to issue an alarm. Preferably, the alarm module includes an alarm display light 341 and a sound transmitter 342, the alarm display light 341 emits a light alarm, and the sound transmitter 342 emits an audio alarm.
