[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 3 The utility model discloses an adjustable cuff, comprising a cuff body 1, and also comprising: a locking shell 2 arranged on the cuff body 1, one side of the locking shell 2 is provided with a mounting assembly for mounting one end of the cuff body 1; a splint 3 for fixing the other end of the cuff body 1, the splint 3 is telescopically arranged on the other side of the locking shell 2, and is fixed by a fixing assembly, and is used to adjust the tightness of the cuff body 1.
[0022] Specifically, the fixing component includes a magnetic block 4 and an electromagnet 5. A placement groove 6 is opened on the side of the locking shell 2, and the electromagnet 5 is installed in the placement groove 6.

[0023] In this embodiment, the other end of the cuff body 1 passes through between the splint 3 and the locking shell 2 to be tightened on the patient's wrist, and then the splint 3 is pressed toward the locking shell 2, and the splint 3 will drive the guide rod 7 to move toward the hole on the surface of the locking shell 2, so that the splint 3 clamps the cuff body 1, and at the same time, the splint 3 drives the magnetic block 4 to be inserted into the placement slot 6 and contact the electromagnet 5, and then the control switch is turned on to allow the battery to energize the electromagnet 5, so that the electromagnet 5 is magnetically connected to the magnetic block 4 to fix the splint 3, and the splint 3 clamps the cuff body 1.
[0024] Specifically, the surface of the clamping plate 3 and the side surface of the locking shell 2 are fixedly provided with corrugated plates 8, the two corrugated plates 8 are meshed with each other, and the two corrugated plates 8 are respectively connected to the two sides of the compression cuff body 1.
[0025] In this embodiment, when the clamp 3 clamps the cuff body 1, the two corrugated plates 8 engage to clamp the cuff body 1, deforming the cuff body 1 into a corrugated shape, thereby increasing the friction with the cuff body 1 and clamping the cuff body 1 more firmly.
[0026] Specifically, a timer 9 is installed on the surface of the locking shell 2 through a groove. The timer 9 is used to remind the blood sampling medical staff to control the pulse pressure time. The timer 9 is electrically connected to the electromagnet 5 through a controller.
[0027] In this embodiment, the timer 9 is started by controlling the switch, and the timer 9 measures the pulse duration. When the duration is exceeded and the compression cuff body 1 is not removed, the timer 9 will sound an alarm to remind the medical staff. At the same time, the controller can control the electromagnet 5 to cut off the power, thereby automatically unlocking the compression cuff body 1 to prevent long-term compression from being harmful to the patient.
[0028] Specifically, the installation assembly includes a cam portion 10 and a toggle plate 11. The toggle plate 11 is integrally formed on the side of the cam portion 10. A through groove 12 is opened on the side of the locking shell 2. The cam portion 10 is hinged to the inner wall of the through groove 12. One end of the compression cuff body 1 is inserted into the through groove 12, and the cam portion 10 fits tightly against the compression cuff body 1.
[0029] In the present embodiment, when installing one end of the cuff body 1 with the locking shell 2, first insert one end of the cuff body 1 into the through groove 12, and then drive the cam portion 10 to rotate around the hinge axis by turning the toggle plate 11, so that the cam portion 10 squeezes the cuff body 1 until it fits tightly, thereby installing the cuff body 1. When disassembling, the cam portion 10 is driven to reverse by the toggle plate 11, so that the cam portion 10 is separated from the cuff body 1, and the cuff body 1 can be disassembled, thereby facilitating the installation and disassembly of the cuff body 1.
[0030] Specifically, a clamping claw 13 is fixedly provided on the surface of the toggle plate 11 . The clamping claw 13 is arranged in an arc shape and is inserted into the surface of the cuff body 1 .
[0031] In this embodiment, the cam portion 10 is driven to rotate around the hinge axis by bending the toggle plate 11, so that the cam portion 10 squeezes the compression cuff body 1. At the same time, the toggle plate 11 will drive the surface claws 13 to be inserted into the surface of the compression cuff body 1 to reinforce the compression cuff body 1.
[0032] Specifically, scale lines 14 are fixedly arranged on the surface of the cuff body 1 , and the scale lines 14 are used to check the tightness of the cuff body 1 .
[0033] In this embodiment, by setting scale lines 14 on the cuff body 1, it is convenient to accurately adjust the tightness of the cuff when drawing blood. For example, if the arm circumference is 40 cm, the appropriate length of the tightened cuff is 35 cm.
[0034] Specifically, a silicone pad 15 is fixedly disposed on the bottom of the locking shell 2 , and the bottom end of the silicone pad 15 is arranged in an arc shape.
[0035] In this embodiment, when the locking shell 2 is placed on the wrist, the silicone pad 15 will contact the wrist, so that the wrist is in the arc groove of the silicone pad 15. The silicone pad 15 can increase the comfort of the wrist when the locking shell 2 is placed.
[0036] The working principle and use process of the utility model are as follows: when in use, one end of the cuff body 1 is installed with the locking shell 2 through the installation component. When the cuff body 1 is used, the cuff body 1 is sleeved on the patient's wrist, so that the other end of the cuff body 1 passes through between the splint 3 and the locking shell 2, and then the other end of the cuff body 1 is pulled to tighten it on the patient's wrist, and then the splint 3 is pressed in the direction of the locking shell 2, and the splint 3 will drive the guide rod 7 to move toward the hole on the surface of the locking shell 2, guide the splint 3, so that the splint 3 clamps the cuff body 1, and at the same time the splint 3 will drive the magnetic block 4 to be inserted into the placement slot 6 and contact the electromagnet 5, a battery is provided in the locking shell 2, and then the control switch is turned on to energize the battery to the electromagnet 5, so that the electromagnet 5 is magnetically connected to the magnetic block 4, the splint 3 is fixed, and the splint 3 is The cuff body 1 is clamped and fixed, and then the medical staff performs intravenous infusion or blood sampling on the patient. After the blood sampling is completed, the electromagnet 5 is powered off by the control switch, the magnetism of the electromagnet 5 disappears, and the electromagnet 5 is disconnected from the magnetic block 4. Then the splint 3 is pulled in the direction away from the locking shell 2 to separate the splint 3 from the cuff body 1, thereby unlocking the cuff body 1. Since the pulse compression time should not be too long, and the medical staff may forget to remove the cuff body 1 from the patient's arm, a timer 9 is set and the timer 9 is started by the control switch. The timer 9 measures the pulse compression time. When the cuff body 1 is not removed after the time is exceeded, the timer 9 will sound an alarm to remind the medical staff. At the same time, the electromagnet 5 can be powered off by the controller, thereby automatically unlocking the cuff body 1 to prevent long-term compression from being harmful to the patient.
[0037] In summary, the adjustable cuff, by providing the locking shell 2 and the splint 3, achieves the effect of tightening and locking the two ends of the cuff by the locking device, so that the cuff is firmly fixed and not easy to break, thereby improving the advantage of stability during use, and solves the problem of tying a rubber tube to the arm of a blood-drawing patient, because some patients have thick or smooth arms, which can easily cause the cuff to unfold, and such repeated tying greatly delays the efficiency of blood collection.
