Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a combinable dorsalis pedis artery pulsation monitoring device. Background Art

[0002] The dorsalis pedis artery is located in front of the ankle joint of the human foot, at the connection end of the medial malleolus and the lateral malleolus, and on the outside of the extensor hallucis longus tendon. Usually, as long as we touch this place, we can feel the pulsation of the dorsalis pedis artery.

[0003] The pulsation of the dorsalis pedis artery has very important significance in medicine. The blood supply of the distal limb can be judged through the pulsation of the dorsalis pedis artery. If the pulsation of the dorsalis pedis artery weakens, it often indicates the following blood circulation system diseases. Weakening of the pulsation on both sides indicates heart failure or insufficient blood volume; weakening of the pulsation on one side indicates abnormal blood circulation in the lower limb, such as arteriosclerosis of the lower limb, vasculitis, or even acute arterial embolism of the lower limb.

[0004] Clinically, patients undergoing interventional treatment or patients with fractures need to monitor the pulsation of the dorsalis pedis artery. In order to facilitate the monitoring of the pulsation of the dorsalis pedis artery, a dorsalis pedis artery pulsation measuring instrument has emerged on the market. The dorsalis pedis artery pulsation measuring instrument includes a dorsalis pedis artery monitoring module for collecting the pulsation times of the dorsalis pedis artery. Straps made of nylon are respectively connected to both ends of the dorsalis pedis artery monitoring module, and the two straps are bonded by Velcro. Clinically, a small number of patients need to continuously monitor the pulsation of the dorsalis pedis artery. Wearing the straps made of nylon for a long time results in poor comfort. Moreover, when monitoring the pulsation of the dorsalis pedis artery, the dorsalis pedis artery monitoring module is fixed at the high point of the instep. The straps made of nylon have a low friction coefficient. When continuously monitoring the pulsation of the dorsalis pedis artery for a long time, even if the patient remains still, the dorsalis pedis artery monitoring module is likely to slide towards the side close to the toes, affecting the monitoring results. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a combinable dorsalis pedis artery pulsation monitoring device, which not only has a reasonable structure, but also can improve the comfort of patients and prevent the dorsalis pedis artery monitoring module from sliding towards the toes.

[0006] To solve the above technical problems, the technical solution of the present utility model is: a combinable dorsalis pedis artery pulsation monitoring device, including a pulsation monitoring module. Both lateral sides of the pulsation monitoring module are hinged with straps. One longitudinal side of the pulsation monitoring module is fixedly connected with a connecting seat, on which an anti - detachment buckle is fixedly provided and connected to a longitudinal strap through the anti - detachment buckle. A plurality of buckling holes for cooperating with the anti - detachment buckle are formed along the length direction of the longitudinal strap. The other ends of the two lateral sides of the longitudinal strap are respectively connected with transverse straps, and the two transverse straps are buckled with each other to be wound around the ankle in a ring shape; a semiconductor piezoresistive sensor and a temperature sensor are arranged at the bottom end of the pulsation monitoring module.

[0007] Further, the two straps are respectively a first strap and a second strap. A plurality of second buckling holes are spaced along the length direction of the first strap. A second anti - detachment buckle for buckling and cooperating with the second buckling holes is fixedly provided at one end of the second strap away from the pulsation monitoring module. The length of the first strap is longer than that of the second strap.

[0008] Further, a plurality of third buckling holes are spaced along the length direction of one of the transverse straps, and a third anti - detachment buckle for buckling and cooperating with the third buckling holes is arranged at the end of the other transverse strap.

[0009] Further, the anti - detachment buckle, the second anti - detachment buckle, and the third anti - detachment buckle have the same structure, and each is composed of a fixing part, a supporting part, and an anti - detachment part. The supporting part is fixedly arranged between the fixing part and the anti - detachment part, and the end face diameter of the supporting part is smaller than the diameter of the buckling hole. The anti - detachment part is conical, and the diameter of the bottom connecting end with the supporting part is larger than the diameter of the buckling hole.

[0010] Further, the pulsation monitoring module includes a housing and a power module, a single - chip microcomputer, a storage module, a data transmission module, a display module, a semiconductor piezoresistive sensor, and a temperature sensor embedded in the housing. The display module is embedded in the top of the housing, and the semiconductor piezoresistive sensor and the temperature sensor are embedded in the bottom of the housing, that is, the detection parts of the semiconductor piezoresistive sensor and the temperature sensor both extend outside the housing. The semiconductor piezoresistive sensor, the temperature sensor, the display module, the storage module, and the data transmission module are respectively electrically connected to the single - chip microcomputer.

[0011] Further, the straps, the transverse straps, and the longitudinal strap are all made of silica gel material.

[0012] Compared with the prior art, the present utility model has the following beneficial effects: The first strap and the second strap made of silica gel material can improve the friction coefficient between the strap and the foot compared with the strap made of nylon material, making the dorsalis pedis artery monitoring module not easy to slide towards the toe side. Moreover, the first strap and the second strap made of silica gel material can also improve the wearing comfort of the patient. By buckling the first strap around the sole of the foot and then buckling with the second anti - detachment buckle on the side of the foot, it is avoided that buckling at the sole of the foot affects the comfort.

[0022] To make the above - mentioned features and advantages of the present utility model more obvious and understandable, specific embodiments are given below and described in detail in conjunction with the accompanying drawings as follows.

[0023] As Figures 1 - 7As shown in the figure, a combinable dorsalis pedis artery pulsation monitoring device includes a pulsation monitoring module 1. Both lateral sides of the pulsation monitoring module are hinged with straps. One longitudinal side of the pulsation monitoring module is fixedly connected with a connecting seat 22. An anti-release buckle 8 is fixedly arranged on the connecting seat and is connected with a longitudinal strap 72 through the anti-release buckle. A plurality of buckling holes 73 that cooperate with the anti-release buckle are formed along the length direction of the longitudinal strap. Both lateral sides of the other end of the longitudinal strap are connected with transverse straps 71. The transverse straps and the longitudinal strap form a connecting strap 7, which can further prevent the dorsalis pedis artery monitoring module from sliding towards the toe side. It can meet the needs of patients to get out of bed and move when monitoring the pulsation of the dorsalis pedis artery. The two transverse straps are buckled with each other to form a ring around the ankle; a semiconductor piezoresistive sensor 16 and a temperature sensor 17 are arranged at the bottom of the pulsation monitoring module. The setting of the buckling holes can adjust the position of the dorsalis pedis artery monitoring module connected to the longitudinal strap 72 according to the foot lengths of different patients, and adjust the dorsalis pedis artery monitoring module to a suitable monitoring position.

[0024] In an embodiment of the present invention, the connecting strap 7 is made of silica gel material. The connecting strap 7 made of silica gel material can improve the comfort of patients.

[0025] In an embodiment of the present invention, the two straps are respectively a first strap 2 and a second strap 3. A plurality of second buckling holes 5 are formed at intervals along the length direction of the first strap. A second anti-release buckle 4 that is buckled and matched with the second buckling holes is fixedly arranged at one end of the second strap away from the pulsation monitoring module. The length of the first strap is longer than that of the second strap, that is, the first strap bypasses the sole of the foot and then buckles with the second anti-release buckle at the side of the foot to avoid buckling at the sole of the foot. After the first strap 2 and the second strap 3 are connected, a ring structure matching the patient's foot sole is formed. The first strap 2 and the second strap 3 made of silica gel material can improve the friction coefficient between the strap and the foot compared with the strap made of nylon material, so that the dorsalis pedis artery monitoring module is not easy to slide towards the toe side. Moreover, the first strap 2 and the second strap 3 made of silica gel material can also improve the comfort of the patient's wearing. Through the setting of the second buckling holes, it can adapt to the foot widths of different patients.

[0026] In an embodiment of the present invention, a plurality of third buckling holes 10 are formed at intervals along the length direction of one of the transverse straps. A third anti-release buckle 9 that is buckled and matched with the third buckling holes is arranged at the end of the other transverse strap. The above setting can meet the thickness of the ankles of different patients, especially for patients with plaster covering the foot surface from the calf.

[0027] In the embodiment of the present utility model, the first anti-disengagement, second anti-disengagement, and third anti-disengagement structures are identical, and each is composed of a fixing part 11, a supporting part 12, and an anti-disengagement part 13. The supporting part is fixedly arranged between the fixing part and the anti-disengagement part, and the diameter of the end face of the supporting part is smaller than the diameter of the buckling hole. The anti-disengagement part is conical, and the diameter of the connection end of the bottom with the supporting part is larger than the diameter of the buckling hole.

[0028] In the embodiment of the present utility model, the pulsation monitoring module includes a housing 14, and a power module 15, a single-chip microcomputer 18, a storage module 20, a data transmission module 21, a display module 19, a semiconductor piezoresistive sensor 16, and a temperature sensor 17 embedded in the housing. The display module is embedded in the top of the housing, and the semiconductor piezoresistive sensor and the temperature sensor are embedded in the bottom of the housing, that is, the detection parts of the semiconductor piezoresistive sensor and the temperature sensor both extend outside the housing. The semiconductor piezoresistive sensor, the temperature sensor, the display module, the storage module, and the data transmission module are respectively electrically connected to the single-chip microcomputer. The data transmission module 21 is a USB module or a Bluetooth module. The bottom of the housing is in an arc shape arched upward to adapt to the instep. After the pulsation monitoring module 1 is fixed on the foot, the detection parts of the semiconductor piezoresistive sensor 16 and the temperature sensor 17 face the patient's foot. The semiconductor piezoresistive sensor 16 is used to monitor the dorsalis pedis artery pulsation condition of the patient, and the temperature sensor 17 is used to measure the temperature of the patient's foot. The dorsalis pedis artery pulsation data and the temperature data of the patient's foot monitored by the semiconductor piezoresistive sensor 16 and the temperature sensor 17 are transmitted to the single-chip microcomputer 18, and the single-chip microcomputer 18 displays the dorsalis pedis artery pulsation data and the temperature data in the display module 19. Moreover, the single-chip microcomputer 18 also stores the dorsalis pedis artery pulsation data and the temperature data in the storage module 20.

[0029] Clinically, most patients only need to monitor the dorsalis pedis artery pulsation once an hour, and each time is 30s. For this part of patients, medical staff can directly obtain the monitored data by viewing the data on the display module 19.

[0030] A small number of patients need to continuously monitor the dorsalis pedis artery pulsation of the patient for 24 hours in order to analyze the dorsalis pedis artery pulsation condition of the patient during the day and night, in the sleep state and the awake state, or in the static state or the active state. For this part of patients, medical staff can regularly transmit the dorsalis pedis artery pulsation data and the temperature data stored in the storage module 20 to the computer through the data transmission module 21 for doctors to view and analyze.

[0031] In the embodiment of the present utility model, anti-slip lines 6 are alternately arranged on the surface of the strap. The anti-slip lines 6 further increase the friction coefficient between the first strap 2, the second strap 3, and the foot.

[0032] In the embodiment of the present utility model, the strap, the transverse band, and the longitudinal band are all made of silica gel material. Compared with the strap made of nylon material, the strap made of silica gel material can increase the friction coefficient between the strap and the foot, making it difficult for the dorsalis pedis artery monitoring module to slide towards the toe side. Moreover, the first strap and the second strap made of silica gel material can also improve the wearing comfort of the patient. In addition, the connecting band made of silica gel material can further prevent the dorsalis pedis artery monitoring module from sliding towards the toe side. It can meet the needs of the patient to get out of bed and move around when monitoring the dorsalis pedis artery pulsation.

[0033] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can obtain other various forms of combinable dorsalis pedis artery pulsation monitoring devices under the inspiration of the present utility model. All equal changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
