Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection, and particularly to an intelligent device for monitoring limb ischemia after IABP and a using method thereof. Background Art

[0002] IABP (Intra Aortic Balloon Pump) is an important cardiac assist device, and the most serious complication of IABP is lower limb ischemia. The reasons for limb ischemia during or after counterpulsation may be: thrombosis, arterial tear or dissection, and blockage of blood flow by the sheath or balloon catheter. If detected in time, the further development of ischemia can be prevented. If not detected in time, it may face decompression by incising the ischemic lower limb, amputation of the lower limb, or toxic shock, and even serious consequences such as patient death. Some patients still have severe limb ischemia after the balloon catheter is removed, and surgical treatment should be considered to save the patient's life.

[0003] In the prior art, to determine whether lower limb ischemia occurs, the lower limbs generally need to be observed. Closely observe the color, temperature, sensation of the skin of the operative limb and the pulsation of the dorsalis pedis artery. Among them, the change in skin temperature is one of the most conventional observation indicators. Under certain room temperature (15 - 25°C), if the temperature of the operative limb drops by more than 2°C compared with the corresponding part of the contralateral limb, it indicates insufficient blood supply to that limb. Generally, nurses judge through the skin changes of the lower limbs at the bedside, especially by perceiving the skin temperature, which lacks accuracy and timeliness. However, arranging nurses to observe the skin changes of the patient's two legs for a long time, perceive the skin temperature, and judge whether ischemia occurs requires a large amount of work. At the same time, it is easy for nurses to observe untimely, resulting in the accidental situation that the patient's leg ischemia is not detected and treated in time. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] In the related art, to determine whether lower limb ischemia occurs, it is generally necessary to observe the lower limbs. Closely observe the color, temperature, sensation of the skin of the operative lower limb and the pulsation of the dorsal artery of the foot. Among them, the change in skin temperature is one of the most conventional observation indicators. Under certain room temperature (15-25 °C), if the temperature of the operative limb drops by more than 2 °C compared with the corresponding part of the contralateral side, it indicates insufficient blood supply to the limb on that side. Generally, nurses perceive the skin temperature through the changes in the skin of the lower limb beside the bed, lacking accuracy and timeliness. However, arranging nurses to observe the skin changes of the patient's two legs for a long time, especially to perceive the skin temperature and judge whether ischemia occurs, has a large workload. At the same time, it is easy for nurses to observe untimely, resulting in the accidental situation that the patient's leg ischemia is not detected in time.

[0036] In view of this, as Figures 1 to 4 shown, some embodiments of the present invention provide an intelligent device for monitoring limb ischemia after IABP, including a detection unit 1, a fixing mechanism 2, an elastic member 3, and a memory; the detection unit 1, the elastic member 3, and the memory are all connected to the fixing mechanism 2, the detection unit 1 is electrically connected to the memory, the detection unit 1 contacts the patient, the detection unit 1 is used to detect the temperature of the patient's leg, the memory is used to store the detection result of the detection unit 1, and the elastic member 3 has a movement tendency to press the fixing mechanism 2 against the patient's leg.

[0037] In the above embodiments, the detection unit 1 can be made of a metal material. The detection unit 1 can be a rectangular sheet of metal. The detection unit 1 can be fixed to the fixing mechanism 2 by means of gluing, bolts or clamping. The fixing mechanism 2 is arranged on the patient's leg or other positions where the temperature change needs to be monitored after surgery. The elastic member 3 can be a spring or an elastic cord. The elastic member 3 can also be a torsion spring or a spring plate. The elastic member 3 is connected to the fixing mechanism 2, so that the fixing mechanism 2 can closely adhere to the patient's leg. The memory can be fixed to the fixing mechanism 2. The memory can be a hard disk. The memory is used to store the temperature information detected by the detection unit 1. Thus, under the action of the elastic member 3 and the fixing mechanism 2, the detection unit 1 can be fixed to the patient's leg, enabling the detection unit 1 to obtain the temperature information of the patient's leg in real time and then transmit it to the memory for storage. The detection is more timely, comprehensive and scientific, solving the technical problem of the existing method relying on manual observation of skin changes, especially perceiving skin temperature changes, resulting in untimely treatment of leg ischemia, achieving the technical effect of no need for long-term manual monitoring, saving manpower and timely detecting unexpected leg ischemia situations of patients.

[0038] An intelligent device for monitoring limb ischemia after IABP provided by some embodiments of the present invention includes a detection unit 1, a fixing mechanism 2, an elastic member 3 and a memory; the detection unit 1, the elastic member 3 and the memory are all connected to the fixing mechanism 2. The detection unit 1 is electrically connected to the memory. The detection unit 1 contacts the patient. The detection unit 1 is used to detect the temperature of the patient's leg. The memory is used to store the detection result of the detection unit 1. The elastic member 3 has a tendency of movement to press the fixing mechanism 2 against the patient's leg. By continuously monitoring the temperature of the leg through the detection unit 1, and fixing the detection unit 1 through the elastic member 3 and the fixing mechanism 2, and at the same time storing the detected result through the memory for convenient observation of the temperature change, the technical problem of the existing method relying on manual observation of skin changes, especially perceiving skin temperature changes, resulting in untimely treatment of leg ischemia is solved, achieving the technical effect of no need for long-term manual monitoring, saving manpower and timely detecting unexpected leg ischemia situations of patients.

[0039] In an alternative embodiment, the fixing mechanism 2 includes a first clamping portion 201 and a second clamping portion 202. One end of the first clamping portion 201 is hinged to one end of the second clamping portion 202. The other end of the first clamping portion 201 and the other end of the second clamping portion 202 are in contact with the patient's leg. Two ends of the elastic member 3 are respectively connected to the first clamping portion 201 and the second clamping portion 202. The elastic member 3 has a tendency of movement to make the other end of the first clamping portion 201 and the other end of the second clamping portion 202 approach each other.

[0040] In an alternative embodiment, a detection unit 1 is respectively connected to the other end of the first clamping portion 201 and the other end of the second clamping portion 202.

[0041] In the above embodiments, the first clamping portion 201 and the second clamping portion 202 are arranged at an angle. The first clamping portion 201 and the second clamping portion 202 are hinged by a hinge post. The first clamping portion 201 and the second clamping portion 202 can both be rod-shaped. After one end of the first clamping portion 201 and one end of the second clamping portion 202 are hinged together, a detection portion 1 can be respectively installed at the other end. The elastic member 3 can be arranged at the middle position between the first clamping portion 201 and the second clamping portion 202. Through the pulling of the elastic member 3, the two detection portions 1 on the first clamping portion 201 and the second clamping portion 202 have a tendency to move closer to each other. Thus, when the first clamping portion 201 and the second clamping portion 202 move closer to each other, the two detection portions 1 can be tightly attached to the patient's leg, so that the temperatures detected by the two detection portions 1 are more accurate. At the same time, different positions of the leg can be detected by multiple detection portions 1, which is convenient for observing the temperature information of each position of the patient's leg.

[0042] Optionally, the first clamping portion 201 and the second clamping portion 202 can be connected to the same leg of the patient. Whether it is the patient's contralateral leg or the postoperative leg to be measured, useful temperature information can be obtained for comparison. By judging whether the temperature of the postoperative leg to be measured is more than 2° lower than the temperature of the patient's contralateral leg, it can be determined whether there is a problem with the postoperative leg to be measured. At the same time, the first clamping portion 201 and the second clamping portion 202 can be respectively connected to one leg of the patient. That is, the first clamping portion 201 can be connected to the postoperative leg to be measured of the patient, and the second clamping portion 202 can be connected to the patient's contralateral leg. By comparing the temperatures measured by the first clamping portion 201 and the second clamping portion 202 in real time, the temperature changes of the two legs of the patient can be judged, so that whether the patient's leg is ischemic can be detected more timely.

The first connecting rod 2011 and the first bent rod 2012 are arranged at an angle, and the second connecting rod 2021 and the second bent rod 2022 are arranged at an angle. The extending directions of the first bent rod 2012 and the second bent rod 2022 are arranged to be closer to each other.

[0044] In the above embodiments, the first connecting rod 2011 and the first bent rod 2012 can both be cylindrical, the second connecting rod 2021 and the second bent rod 2022 can also be cylindrical, the first connecting rod 2011 and the first bent rod 2012 can be integrally formed, the second connecting rod 2021 and the second bent rod 2022 can also be integrally formed, the first connecting rod 2011 and the second connecting rod 2021 can both be made of metal material, and in order to facilitate clamping the leg, the first bent rod 2012 and the second bent rod 2022 both extend towards the leg direction, so as to conveniently press the first bent rod 2012 and the second bent rod 2022 against the patient's leg, avoiding interference between the first connecting rod 2011 and the second connecting rod 2021 and the patient's leg, and making it more convenient to use.

The display can pass through the housing 203 and display the measured temperature outward. The processor can be a PLC or a computer. The processor can be electrically connected to the display, the alarm, the detection unit 1, and the memory by wired or wireless means, so that the temperature information detected by the detection unit 1 can be transmitted to the processor. The processor stores the temperature information in the memory. Then, the detection unit 1 transmits the newly detected temperature to the processor. The processor compares the newly detected temperature with the temperature stored in the memory to judge the temperature difference. The processor transmits the previously detected temperature, the newly detected temperature, and the temperature difference to the display for display, which is convenient for the operator to view.
