[0002] The internal arteriovenous fistula is a common blood vessel access for maintenance hemodialysis patients, which has the advantages of safety, sufficient blood flow and less infection opportunity. The use of general internal fistula can be maintained for 4-5 years. Generally, the patient needs to be pressed for 15-30 minutes after hemodialysis treatment, and most of the maintenance hemodialysis patients are old patients, and most of the patients are alone in the hospital for hemodialysis treatment. After the operation, the patient is weak, and the finger pressure hemostasis force is not enough or even cannot be taken, which leads to repeated bleeding of the internal fistula.

[0003] The patent with publication number CN217244631U discloses an internal fistula bleeding protection alarm for hemodialysis patients, which comprises a fixing seat, a charging and air pump, an alarm, a protective sleeve, a hemostatic air cushion, a pressure sensor, a connecting rope and a liquid sensor. When in use, the patient's internal fistula arm can be inserted into the protective sleeve, and the liquid sensor is placed on the gauze in the internal fistula area. When the liquid sensor detects internal fistula bleeding, it can trigger a high level to the alarm, which is conducive to the sound alarm of the alarm, so as to achieve the purpose of reminding the patient and medical staff. At the same time, when the liquid sensor detects internal fistula bleeding, it can also trigger a high level to the charging and air pump, which is conducive to the inflation of the hemostatic air cushion after the charging and air pump is started, and the inflation of the hemostatic air cushion to the protective sleeve inside, which can stop the work of the charging and air pump when the pressure value exceeds the original setting value, so as to realize the purpose of controlling the expansion size of the hemostatic air cushion.

[0049] In order to prevent the internal fistula from bleeding too much and staining the humidity sensor 3, affecting the service life of the humidity sensor 3, a water absorption layer is arranged in the limiting through hole 21, wherein the water absorption layer is detachably connected with the connecting cloth 1, and when the internal fistula bleeds, the water absorption layer is in contact with the hemostatic cotton ball, so that the excess blood can be absorbed. Embodiment 2

[0050] Based on embodiment 1, different from embodiment 1, the portable hemodialysis nursing hemostatic device with an alarm function provided by the embodiment of the utility model further comprises a vibration sensor 11. The vibration sensor 11 is connected with the controller 7.

[0051] The vibration sensor 11 is arranged on one side of the humidity sensor 3, and the vibration sensor 11 is arranged in the axial direction of the patient's arm, so as to monitor the tremor of the internal fistula.

[0052] Similar to the humidity sensor 3, the vibration sensor 11 is fixedly connected with the connecting cloth 1 through the limiting box 8, and the vibration sensor 11 is located at the side of the humidity sensor 3 and above the arteriovenous vessel; in this way, in the process of wearing the portable hemodialysis nursing hemostasis device, after the vibration sensor 11 monitors the vibration, the medical staff or the patient is reminded to manually close the air pump 9, to stop inflating the compression air bag 5, to prevent the compression air bag 5 from being too large in compression strength on the internal fistula, and to cause the patient to be uncomfortable.

[0053] It should be noted that the vibration sensor 11 provided in the embodiments of the present application is a prior art, and the structure of the vibration sensor 11 is not improved in the embodiments of the present application. For example, the model of the vibration sensor 11 is MEAS CM-01B, YT-JB3.

[0054] Application case:

[0055] A patient surnamed Yao has been treated with regular hemodialysis through a left forearm arteriovenous fistula for 12 years. In recent days, the blood flow of the arteriovenous fistula is poor during dialysis, and the anastomotic stoma is painful and uncomfortable. It is determined that the patient has arteriovenous fistula stenosis, and after arteriovenous fistula balloon dilatation, the internal fistula needs to be pressed for hemostasis.

[0056] Step one: place the hemostatic cotton ball above the internal fistula;

[0057] Step two: align the limiting through hole 21 of the adhesive piece 2 with the hemostatic cotton ball, and then paste the adhesive piece 2 on the surface of the patient's skin, at this time, the humidity sensor 3 is located above the internal fistula;

[0058] Step three: adjust the tightness of the alarm compression band 4, so that the alarm compression band 4 is fixed after winding around the patient's left forearm once;

[0059] Step four: inflate the compression air bag 5 through the air pump 9 in the alarm hemostasis combined assembly to achieve hemostatic compression of the internal fistula;

[0060] In this step, if the vibration sensor 11 monitors the vibration of the internal fistula, the medical staff or the patient is reminded to manually close the air pump 9 to prevent the compression air bag 5 from being too large in pressure, and to avoid excessive compression. At this time, the portable hemodialysis nursing hemostasis device with an alarm function is worn.

[0061] In the subsequent use process, if the humidity sensor 3 detects bleeding of the internal fistula, the air pump 9 in the alarm hemostasis combined assembly inflates the compression air bag 5, and at the same time, the medical staff manually closes the air pump 9 according to the vibration value monitored by the vibration sensor 11 to prevent the compression air bag 5 from being too large in pressure. After the hemostatic compression is completed, the medical staff can take off the portable hemodialysis nursing hemostasis device with an alarm function, and then replace the new hemostatic cotton ball and wear the alarm compression band 4 again to prevent the internal fistula of the patient from bleeding again subsequently.

[0062] That which is not described in detail in the specification is considered to be of prior art by those skilled in the art.
