Description

Intelligent elastic medical restraint strap

Technical Field

The invention relates to the field of medical auxiliary instruments, in particular to a medical restraint strap.

Background

Clinically, the restraint strap is mainly used for protecting a patient who moves, limiting the body of the patient or restraining the uncontrolled limb movement of the patient, and preventing the patient from self-injuring or falling down. When in use, the restraint strap needs to be bound on the limb of a patient for a long time, and unsmooth blood circulation at the tail end of the bound limb is easy to cause. In the prior art, the restriction is usually prevented from being too tight to cause unsmooth blood circulation by adjusting the tightness degree of the restriction band, for example, the chinese utility model patent with publication number CN205795882U discloses a medical restriction band, which adjusts the tightness degree of the restriction by manually adjusting the length between the buckles of the restriction band. However, in actual use, in order to ensure the effect of restraint, the blood circulation is still not smooth after long-time use after the tightness degree of the restraint strap is manually adjusted. The patient does not have continuous dryness, so that the restraint force of the restraint strap can be relaxed to a certain degree when the patient is in a quiet state, and the restraint strap needs to provide enough restraint force to ensure the safety of the patient when the patient is in a dry state. Therefore, it is important to develop a restraint band capable of automatically adjusting a restraint force according to the state of a patient.

Disclosure of Invention

In order to solve the above problems, the present invention provides an intelligent elastic medical restraint strap, which is capable of automatically adjusting the degree of tightness of the restraint strap according to the activity state of a patient, automatically relaxing the restraint strap when the patient is in a resting state, improving the blood circulation of the limbs of the restraint part, automatically tightening the restraint strap when the patient is in a dry state, ventilating the restraint part, and reducing the injury of the restraint strap to the body.

In order to achieve the purpose, the invention provides an intelligent elastic medical restraint strap which comprises a wrist strap, a nylon adhesive strip, a buckle and a lock catch, wherein the lock catch is connected with the wrist strap through a rope, an air bag group is arranged in an interlayer in the wrist strap, a ventilation board is arranged on the inner surface layer of the wrist strap, the nylon adhesive strip and an acceleration sensor are arranged on the outer surface layer of the wrist strap, the acceleration sensor is connected with a host machine through a cable sleeve, the air bag group is connected with the host machine through an air guide pipe along the cable sleeve, and the ventilation board is connected with the host machine through the air guide pipe along.

Furthermore, the air bag group consists of a plurality of air bags which are distributed in the inner interlayer of the wrist strap, and the air bags are connected through a pipeline.

Further, the ventilation board is covered with a liner on the surface.

Furthermore, a pressure air pump, a ventilation air pump and a microcomputer chip are arranged in the host, the air bag group is connected with the pressure air pump in the host through an air duct, the ventilation plate is connected with the ventilation air pump through the air duct, and the acceleration sensor is connected with the microcomputer chip in the host through a cable.

Furthermore, a winder and a winder locking device are arranged in the lock catch.

Because the air bag group is arranged in the wrist strap, the wrist strap has the advantages that the air pressure in the air bag group can be automatically adjusted through the pressure air pump in the host machine, the size of the air bag is changed, and the tightness degree of the wrist strap is further controlled. The wrist strap is provided with the acceleration sensor, the acceleration value of the wrist strap can be collected, the motion state of the wearer is judged through the microcomputer in the host, the restraint strap is automatically tightened or loosened through the pressure air pump in the host under the control of the microcomputer, the damage to the wearer caused by long-time over-force restraint is avoided, and the discomfort of the wearer is reduced. The ventilation board on the inner wall of the restraint strap can continuously ventilate the contact part of the restraint strap and the skin through the ventilation air pump in the host machine, so that the temperature of the contact part of the restraint strap and the skin is reduced, and the discomfort of a wearer is further reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

FIG. 1 is a schematic view of an intelligent, elastic medical restraining strip according to the present invention. When a patient needs to be restrained, the nylon adhesive strip 4 on the wrist strap 5 is opened and taken out from the buckle 6, the wrist strap 5 can be unfolded, the wrist strap 5 annularly wraps the limb of the patient, and the nylon adhesive strip 4 penetrates through the buckle 6 and is reversely adhered to the nylon adhesive strip 4, so that the wrist strap 5 can be fixed on the limb of the patient. Then, the length of the rope is adjusted by using the rope winder arranged in the lock catch 11, the lock catch is fixed on a guardrail or other objects of the hospital bed, and the rope winder arranged in the lock catch 11 is locked, so that the patient can be bound. After the binding of the wrist strap 5 and the lock catch 11 is completed, the host machine 10 is opened, the host machine 10 is utilized to control the pressure air pump inside the host machine to adjust the size of the air bag group 3 inside the wrist strap 5, and then the tightness degree of the wrist strap for the arm restraint of the patient is adjusted. After accomplishing the setting to host computer 10, host computer 10 can judge patient's state through 5 outer surface mounting's of wrist strap 7, when acceleration sensor 7 detected acceleration numerical value and is less than the limit value in a certain duration, judge that the patient is in the state of rest, host computer 10 can control inside pressure air pump and reduce 5 inside gasbag group 3's of wrist strap air pressure, and then reduce the volume of gasbag, reduce the restraint of restraint strap to the patient, prevent that the wrist strap from extrudeing the patient for a long time and causing blood circulation not smooth. When the acceleration sensor 7 detects an acceleration value exceeding a set value, the host 10 controls the internal pressure air pump to increase the air pressure of the air bag group 3 in the wrist strap 5, so as to increase the volume of the air bag and restore the normal restraint on the patient. When the wrist strap is restrained normally, the host machine 10 can blow air to the ventilating plate 2 by controlling a ventilating air pump inside the host machine, so that the temperature of the contact part of the wrist strap 5 and the skin of a patient is reduced, and the damage of the wrist strap restraint to the skin of the patient is reduced.
