Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to an electrocardiograph limb clamp and a chest suction ball heating device. Background Art

[0002] When patients seek medical treatment, electrocardiogram (ECG) is a routine examination item, and it accounts for a large proportion of the number of examinations. The ECG examination process begins with the patient lying flat on the examination bed to ensure that the body is relaxed and the heart is functioning smoothly. Next, the doctor will place limb clamps on the patient's limbs and chest suction bulbs (hereinafter referred to as ECG leads). ECG leads are in contact with the human body through metal parts, and the wires are connected to the ECG machine.

[0003] The metal part of the ECG lead has a low specific heat capacity. In most parts of northern my country in winter, when the ECG lead is placed for the patient, the cold metal will stimulate the patient's muscles and make the patient very uncomfortable. When performing an ECG examination, the patient needs to remain still to avoid muscle shaking or body movement. These movements will cause irregular clutter on the ECG machine or irregular, wide and deformed wave groups in the QRS wave group, which can easily be misdiagnosed as arrhythmias such as premature beats. By counting the proportion of ECG examinations and outpatient visits in a tertiary hospital, it was found that the number of ECG examinations accounted for about one-tenth of the number of outpatient visits. Hundreds of people are examined every day, and complaints and disputes also occur due to the discomfort of cold stimulation. In order to improve the comfort of ECG examinations and reduce the misdiagnosis rate of ECG examinations, an ECG lead heating device is needed to keep the ECG lead at a suitable temperature when on standby to avoid cold stimulation when in contact with the human body.

[0004] To this end, the utility model provides an electrocardiograph limb clamp and a chest suction ball heating device. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-4 A limb clamp and chest suction ball heating device for an electrocardiograph comprises a treatment cart 1, an electrocardiograph 2 is installed on the treatment cart 1, and a lead harness 3 is inserted into the electrocardiograph 2, and a plurality of limb clamps 4 and a chest suction ball 5 are respectively installed on the outer ends of the lead harness 3, a plurality of fences 6 are fixedly connected to the upper end of the treatment cart 1, and a cylindrical heating silicone plate 8 is bonded to the fence 6 on the left side, a rectangular heating silicone plate 9 is bonded to the upper end of the treatment cart 1, a temperature control and adjustment device 7 is installed on the upper end of the treatment cart 1, and the temperature control and adjustment device 7 is electrically connected to the cylindrical heating silicone plate 8 and the rectangular heating silicone plate 9 respectively, a plurality of limb clamps 4 are clamped on the cylindrical heating silicone plate 8, and a plurality of chest suction balls 5 are placed on the rectangular heating silicone plate 9.

[0027] During use of the present solution, take out the power plug 11 and insert it into the socket to turn on the power, so that the temperature control device 7 drives the first heating resistor 801 and the second heating resistor 901 to heat respectively, so that the temperature of the cylindrical heating silicone plate 8 and the rectangular heating silicone plate 9 increases. The cylindrical heating silicone plate 8 and the rectangular heating silicone plate 9 made of silicone material have the characteristics of heat resistance, easy molding, easy cleaning, environmental protection, etc., are easy to use, and their flexibility is not available in other heating sheets or heating plates, so that they can fit tightly with the treatment vehicle 1 to prevent falling off. The heated cylindrical heating silicone plate 8 and the rectangular heating silicone plate 9 respectively conduct heat to multiple limb clamps 4 and the chest suction ball 5 by heat conduction, so that when the metal part contacts the human body, it is not easy to stimulate the patient's muscles due to the cold, thereby improving the comfort of the electrocardiogram examination and reducing the misdiagnosis rate of the electrocardiogram examination. At the same time, the first temperature sensor 802 and the second temperature sensor 902 will also detect the temperature of the cylindrical heating silicone plate 8 and the rectangular heating silicone plate in real time. The temperature of the hot silicone plate 9, the first temperature sensor 802 and the second temperature sensor 902 select the thermistor NTCB4537, which is a resistance value variable temperature sensor. For nonlinear changes in temperature, the nonlinearity of the NTC thermistor is very serious. Therefore, in practical applications, the nonlinear processing of the NTC thermistor is very critical. This type of thermistor has a nominal resistance of 230kΩ at 25°C, a B value of 4537, and an allowable deviation accuracy of ±3%. The power supply part, after AC-DC conversion, is powered by ±15V and a constant current drives the thermistor, and then the temperature is transmitted to the temperature control and adjustment device 7. The temperature control and adjustment device 7 is provided with a three-digit digital diode for displaying the temperature, and the third digit is a decimal, which is simple and intuitive. When the temperature of the cylindrical heating silicone plate 8 and the rectangular heating silicone plate 9 exceeds 50°C, the high temperature protection device is activated, the power supply is disconnected and the heating is stopped, and the temperature control and adjustment device 7 is designed to be more compact than similar products, only 75*35*80mm in size.

[0029] During use of this solution, the first heating resistor wire 801 is heated after the temperature control and adjustment device 7 is powered on, and the heat is transferred to the limb clamp 4 by heat conduction for heating. The first temperature sensor 802 detects the temperature on the cylindrical heating silicone plate 8 in real time and transfers it to the temperature control and adjustment device 7, so that when the temperature exceeds 50°C, the high temperature protection device is activated, the power is disconnected and the heating is stopped. The cylindrical heating silicone plate 8 is rolled into a cylinder with a circumference of 150mm by adopting a 150*150mm rectangle.

[0031] During use of this solution, the second heating resistor wire 901 is heated after the temperature control and adjustment device 7 is powered on, and the heat is transferred to the chest suction ball 5 by heat conduction for heating. The second temperature sensor 902 detects the temperature on the rectangular heating silicone plate 9 in real time and transfers it to the temperature control and adjustment device 7, so that when the temperature exceeds 50°C, the high temperature protection device is activated, the power is disconnected and the heating is stopped. The rectangular heating silicone plate 9 is a 300*200mm rectangle.

[0032] See also Figure 1 The cylindrical heating silicone plate 8 is bonded to the fence 6 on the left side through Velcro, and the rectangular heating silicone plate 9 is bonded to the upper end of the treatment vehicle 1 through 3M glue.

[0033] During use of this solution, the cylindrical heating silicone plate 8 can be fixed to the fence 6 through the bonding method of Velcro, and the silicone material has the characteristics of flexibility, so it can fit tightly with the treatment vehicle 1 to prevent falling off, and the rectangular heating silicone plate 9 can be fixed to the upper end of the treatment vehicle 1 through the bonding method of 3M glue.

[0034] See also Figure 1 A power cord 10 is installed at the rear end of the temperature control and adjustment device 7, and a power plug 11 is installed at the outer end of the power cord 10.

[0035] During use of the present solution, the power cord 10 and the power plug 11 can be used to drive the temperature control and adjustment device 7 to be connected to the power supply and to perform power-on operation.
