Description

A portable heart rate monitor for patients with heart failure

Technical field

The present invention relates to the field of medical equipment, specifically to the field of heart rate monitoring equipment, and in particular to a portable heart rate monitor for patients with heart failure.

Background technique

Heart rate monitors have played a significant role in the research, diagnosis and treatment of cardiovascular diseases. They record patients' heart activities, such as heart rate, respiration, pulse, etc. Some heart failure patients need to monitor themselves even at home due to their serious condition. For real-time monitoring, this requires miniaturization and portable improvement of the heart rate monitor so that patients can use it anytime and anywhere. In the current existing technology, common portable monitors are similar to sports bracelets and can be worn on the patient's arm. The patient's body is monitored in real time. However, these portable monitors are commonly worn similar to sports bracelets or watches, which can ensure that they do not fall off the patient's arm. However, the comfort is not good, such as watches, because different people's arms have different thicknesses. 1. Although it can be adjusted through the strap, the adjustment distance of the strap is an integral multiple of the distance between two adjacent strap holes each time. As a result, after the adjustment is completed, the strap is either a little loose and easy to slip off. , or a little too tight, making it uncomfortable to wear for a long time. In addition, this way of wearing has poor ventilation and breathability, and weather with higher temperatures can easily cause redness and swelling in the wearing area. In addition, there are other common ways of wearing on the market. There is also a cuff type. For example, in the patent document with authorization announcement number CN108714024B and the patent document with application publication number CN111839481A, the inflatable cuff method is used to wear the monitor. Although it can adapt to the thickness of the patient's arm and is comfortable to wear, it The entire arm of the patient is wrapped by the cuff, which can easily cause itching, redness, and swelling in the wearing area in the summer. In addition, poor ventilation and breathability can easily cause sweat stains to remain on related electronic components, affecting the accuracy of the monitoring structure.

Based on the above, the present invention proposes a portable heart rate monitor that is easy to wear, comfortable and has good ventilation and breathability.

Embodiment 1

Referring to Figures 1-9, a portable heart rate monitor for heart failure patients includes a wearing component 100 and a monitoring component. The wearing component 100 is used to adapt to the thickness of the patient's arm and be worn on the patient's arm, and has good ventilation and breathability. , the monitoring component is used to monitor the patient's body.

Referring to Figure 4, the wearing member 100 includes a mounting ring 101 and a clamping plate 109 slidably installed in the mounting ring 101 along the radial direction of the mounting ring 101. The clamping plate 109 is driven to move by the driving assembly 108, and the clamping plate 109 moves along the mounting ring. There are several circumferential arrays of 101, three of which are shown in the drawings of this plan.

The clamping plate 109 is in the shape of an arc plate with an axis parallel to the axis of the mounting ring 101. A rib 110 is provided on the inner circular surface of the clamping plate 109. The extending direction of the rib 110 is in line with the axis of the clamping plate 109. The lines are arranged at an included angle, and several ribs 110 are arranged in an array along the axis direction of the clamping plate 109 .

Referring to Figures 1 and 4, the outer circumferential surface of the mounting ring 101 is provided with a support 102. The monitoring component includes a monitor 200 installed on the support 102. The monitoring element of the monitor 200 is provided on the clamping plate 109 and located adjacent to it. Between two adjacent ribs 110, the battery, display screen and other structures of the monitor 200 are arranged on the support 102, and the monitoring method may be photoplethysmography.

The working principle of Embodiment 1 is:

First, the patient puts the arm through the mounting ring 101 and makes the monitoring position of the arm located in the mounting ring 101. Then, the driving assembly 108 drives the clamping plate 109 to move close to the arm, and finally completes the clamping of the arm. The clamping process Among them: 1. The patient adjusts the clamping plate 109 according to his or her own comfort to realize the purpose of adaptive arm thickness and wearing the present invention on the patient's arm and the patient's better wearing comfort, and it is relatively simple and convenient to put on or take off; 2. After wearing it, there is a blank area around the wearing part of the arm, so that the air can flow normally and the ventilation and breathability are good; 3. In hot weather such as summer, a large amount of sweat beads will inevitably be produced on the arm. It is easy to cause the present invention to slip, and the arrangement of the ribs 110 can not only prevent slipping and falling off, but also guide sweat beads to flow away, so as to prevent sweat beads from remaining on the clamping plate 109 , that is, it stays near the monitoring element, which affects the monitoring results. In the long run, the moisture of the sweat beads can easily penetrate into the monitoring element, affecting the use of the monitoring element. Furthermore, if the rib 110 is not at an angle with the clamping plate 109 arrangement, but parallel or perpendicular to the axis of the clamping plate 109, then when the patient's arm rests on the table or the patient lies flat, that is, when the patient's arm is placed in a horizontal position, the sweat beads are easily parallel to the clamping Intercepted by the ribs 110 of the axis line of the plate 109, it is difficult to flow and leave the area between two adjacent ribs 110 under the action of gravity. When the patient's arm is vertical, that is, the patient's arm is placed in a vertical position. When the sweat beads are inserted, the sweat beads are easily intercepted by the ribs 110 perpendicular to the axis of the clamping plate 109, and it is also difficult to leave the area between the two adjacent ribs 110. In contrast, in this solution, the extension direction of the ribs 110 is consistent with the direction of the ribs 110. The axis lines of the clamping plates 109 are arranged at an angle, so that the ribs 110 can be arranged at an angle during the patient's daily activities. Under the action of gravity, sweat beads can easily flow away along the ribs 110, which not only It will increase the ventilation and breathability performance of the present invention, and also prevent sweat beads from affecting the accuracy of the monitoring structure.
