Description

Technical Field

[0002] Treatment and prevention of deep vein thrombosis (DVT) typically involve the sequential and rhythmic inflation and deflation of a multi-chambered inflatable balloon using a pressure-inflating device. This creates circulatory pressure on the limb tissues, compressing the muscles of the lower extremities and simultaneously massaging the muscle tissue at the treatment site. During intermittent inflation, the venous blood flow velocity is increased, thus helping to prevent DVT and achieving the goal of preventing this condition.

However, heating directly with heating wires inside the pressure leg sleeves may result in uneven heating, and the constant proximity of the heating wires to the patient's limbs can easily cause discomfort or burns.

[0040] The gas delivery pipe is equipped with a heating wire, which is electrically connected to the control system.

[0041] The following will further describe a thrombosis prevention device according to an exemplary embodiment.

[0042] In some implementations, refer to Figures 1-3 as well as Figure 7The aforementioned host is equipped with an air pump body and a control system electrically connected to the air pump body. The air pump body is connected to the pressure leg sleeve through a gas delivery pipe for delivering pressurized gas to the pressure leg sleeve. The aforementioned control system is used to control the opening and closing of the air pump body and the interval time of air inflation and pressurization, thereby realizing intermittent air inflation and pressurization of the pressure leg sleeve.

[0043] Reference Figure 4 The gas delivery pipe is equipped with a heating wire, which is electrically connected to the control system. The control system controls the heating wire to heat up, thereby heating the pressurized gas delivered in the gas delivery pipe. The heated gas is then delivered to the pressure leg sleeve, which is heated evenly. This achieves uniform heating of the patient's limbs, preventing hypothermia or burns and improving the safety of the equipment.

[0044] As a preferred implementation method, refer to Figure 2 The aforementioned pressure leg sleeve is equipped with an air temperature sensor and a body temperature sensor. The air temperature sensor detects the temperature of the heating gas, and the body temperature sensor detects the patient's body temperature. Both temperature sensors can be NTC temperature sensors, which can calculate the temperature by measuring the resistance value. The air temperature sensor and the body temperature sensor are electrically connected to the control system, sending the detected temperature data to the control system for processing and display on the host's touchscreen display. Preferably, the air temperature sensor is located inside the pressure leg sleeve and can contact the pressurized gas, ensuring accurate gas temperature detection; the body temperature sensor is located on the side of the pressure leg sleeve that contacts the patient, enabling accurate detection of the patient's body temperature, thus allowing medical personnel to accurately obtain patient information.

[0045] As a preferred implementation method, refer to Figure 1 and Figure 4 The aforementioned host unit has a first magnetic connector embedded in its side wall.

The first gas channel is connected to the air pump body; the first conductive contact is electrically connected to the control system. (Refer to...) Figure 4 and Figure 6One end of the gas delivery pipe is provided with a second magnetic connector adapted to mate with the first magnetic connector. The second magnetic connector has a second gas channel and a second conductive contact. The second gas channel matches the first gas channel so that when the first magnetic connector mates with the second magnetic connector, the inflation pump body is connected to the gas delivery pipe, allowing gas to be delivered to the gas delivery pipe. The second conductive contact is connected to the heating wire and matches the first conductive contact, so that when the first magnetic connector mates with the second magnetic connector, the first and second conductive contacts make contact and conduction, forming a current loop between the heating wire and the control system, thereby controlling the heating wire to heat the gas in the gas delivery pipe.

[0046] Reference Figure 4 The other end of the aforementioned gas delivery pipe is equipped with a third magnetic connector, which has a third gas channel. (Refer to...) Figure 3 The pressure leg sleeve is provided with a fourth magnetic connector adapted to be connected to the third magnetic connector. The fourth magnetic connector is provided with a fourth gas channel, which matches the third gas channel so that after the third magnetic connector and the fourth magnetic connector are connected, the gas delivery pipe is connected to the pressure leg sleeve, and the heated gas can be delivered to the pressure leg sleeve.
