Problems solved by technology

However, the current arm exercise methods require the patient to massage and exercise the arm regularly. However, the patient cannot complete the arm exercise at night when sleeping, and it is easy to appear that the improper sleeping posture compresses the operated limb and slows down the blood flow. In this case, it is precisely the internal fistula thrombosis that is most likely to occur. Many patients often wake up and the internal fistula is blocked and discarded.
At this time, the patient needs to undergo arteriovenous fistula operation again, delaying the dialysis time, thus spending a lot of manpower and material resources, and also increasing the hospitalization time and cost, and making the patient suffer more physical pain and psychological torture

Embodiment 1

[0038] The bracelet for arteriovenous fistula care includes a bracelet body 1, which is worn by medical personnel on the patient's arm during use. In this embodiment, the bracelet body 1 is made of rubber. as attached figure 1 , attached figure 2 As shown, a three-way pipe 2 is placed inside the bracelet body 1, and the three-way pipe 2 includes a first section, a second section, and a third section that communicate with each other. The port of the first section communicates with the inner wall of the bracelet body 1, and the second section The port of the section communicates with the outer wall of the bracelet body 1, the second section is equipped with a solenoid valve 22, the port of the third section is bonded with a connecting pipe 3, and the end of the connecting pipe 3 away from the third section extends out of the bracelet body 1.

[0039] One end of the connecting pipe 3 protruding from the wristband body 1 is a connecting part 61, which is used to connect with the...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that: Figure 4 As shown, the high-pressure gas is charged through the micro-air pump, and the port of the third section of the tee pipe 2 is bonded to the air outlet of the micro-air pump. The micro-air pump can be placed inside the bracelet body 1 or placed on the bracelet body 1 In this embodiment, the micro air pump is placed on the outer wall of the bracelet body 1, and the micro air pump is bonded with a strap, which is used to fix the micro air pump on the patient's arm.

[0050] The inner wall of the wristband body 1 is also bonded with a heart rate detection module 53, the heart rate detection module 53 is located between the two rubber bladders 4, and when the rubber bladders 4 shrink, the heart rate detection module 53 is against the patient's arm without pressure. The control module is in signal connection with the heart rate detection module 53, the heart rate detection module 53 is used to collect ...

Embodiment 3

[0054] The difference between this embodiment and Embodiment 1 is that: Figure 5 , 6 As shown, the high-pressure gas is charged through the micro-air pump, and the port of the third section of the tee pipe 2 is bonded to the air outlet of the micro-air pump. The micro-air pump can be placed inside the bracelet body 1 or placed on the bracelet body 1 In this embodiment, the micro air pump is placed on the outer wall of the bracelet body 1, and the micro air pump is bonded with a strap, which is used to fix the micro air pump on the patient's arm.

[0055] The inner wall of the wristband body 1 is bonded with a massage airbag. The massage airbag is a circular airbag made of rubber. The surface of the massage airbag is provided with a number of rubber protrusions for massaging the patient's arm. The rubber protrusions are hemispherical. The air bag is provided with a first sucker 6 on the side away from the inner wall of the bracelet body 1, as attached Figure 7 As shown, the...

Abstract

The invention relates to the technical field of medical appliances for passive exercise and particularly relates to a wristband for nursing internal arteriovenous fistula. The wristband for nursing the internal arteriovenous fistula comprises a wristband body used by a patient, wherein a three-way pipe is arranged inside the wristband body. three ends of the three-way pipe are separately connectedwith a connecting pipe, a massage airbag and an electromagnetic valve, the connecting pipe, the three-way pipe and the massage airbag communicate with one another, one end, far away from the three-way pipe, of the connecting pipe is used for inflating high-pressure gas, the massage airbag is located on the internal wall of the wristband body and is in contact with an arm of the patient, and a control module is further arranged inside the wristband body, is in signal connection with the electromagnetic valve and is used for controlling the make and break of the electromagnetic valve. By adopting the scheme, massage exercise on the arm of the patient subjected to an internal arteriovenous fistula surgery can be carried out to prevent angiemphraxis.

Description

technical field [0001] The invention relates to the technical field of medical devices for passive exercise, in particular to a bracelet for arteriovenous fistula care. Background technique [0002] Arteriovenous fistula is one of arteriovenous surgery, mainly used for hemodialysis treatment, it is the lifeline of hemodialysis patients, responsible for leading the blood out of the extracorporeal circulation device and back into the channel of the patient's blood vessels. The commonly used fistula operation in the prior art comprises two kinds, one is to suture the artery and the adjacent vein of the forearm near the arm through arteriovenous fistula, so that arterial blood flows in the vein after the anastomosis, forming an arteriovenous fistula. Venous fistula, the second is to suture the two ends of the artificial blood vessel to the artery and vein respectively through the arteriovenous fistula, so that the arterial blood flows into the venous blood through the artificial...
