Description

Technical Field

[0001] The utility model relates to a medical protection belt, in particular to a semi-fixed protection belt used for hemodialysis. Background Art

[0002] Uremia patients need to undergo hemodialysis regularly, and the treatment process of hemodialysis is relatively long. One hemodialysis session generally takes 4-5 hours. During the hemodialysis process, patients may inadvertently move their hands, causing the hemodialysis puncture needle to puncture a blood vessel or the puncture needle to fall out. Hemodialysis patients also have other types of catheters inserted for treatment needs, such as drainage tubes, endotracheal tubes, gastric tubes, urinary catheters, etc. The insertion of catheters makes patients feel uncomfortable, and patients may inadvertently move or even pull out the catheters with their hands. For patients who are in a semi-comatose state or are irritable or mentally abnormal, this situation is very likely to occur, and the consequences are very serious.

[0003] In order to prevent such unplanned extubation events, the method used is to fix the patient's body, mainly to protect the hands. At present, hand restraints are often restrained by pallets or gloves. Pallet restraint is to fix the fingers and wrists on the pallet by means of finger sleeves and binding, thereby limiting the movement of fingers and flexion of the palm, but this method is not comfortable, and the palm is in an extended state for a long time, which can easily cause muscle tension and stiffness of the metacarpophalangeal joints; glove restraint is to put the hand in a glove, but the gloves are generally made of soft materials, and the fingers and palms still have room for movement, and the patient is likely to break free. At the same time, the ventilation of the hand becomes worse, which can easily cause skin hygiene problems. In addition, due to the coverage of the gloves, the nursing staff cannot check the blood circulation of the hand at any time, whether the oxygen saturation finger sleeve has fallen off, etc., and the gloves need to be opened repeatedly, which increases the workload of the nursing staff. Chinese utility model patent ZL 202221516288.4 discloses a webbed restraint belt, which consists of a wearing opening and a plurality of finger holes. Adjacent finger holes are connected with connecting webs to restrain finger movements. Fingers can be exposed through the finger holes to facilitate treatment operations. However, since soft materials are used and the hand cannot be fixed in a specified position, there is still a possibility of removing the tube after pinching the fingers. In addition, this restraint belt covers the back of the hand, making it impossible to perform intravenous infusion on the back of the hand, and when it is used on the hand on the side of the hemodialysis puncture, the constraint of the wearing opening at the wrist will compress the blood vessels at the puncture site, resulting in reduced blood flow and affecting treatment. Utility Model Content

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a semi-fixed protective belt for hemodialysis, which allows the restrained hand to move within a certain range but the fingers cannot be pinched, and the back of the hand is completely exposed to facilitate intravenous infusion.

[0021] Embodiment Semi-fixed protective belt for hemodialysis

[0022] In this embodiment, Figure 1 , Figure 2 As shown, a semi-fixed protective belt for hemodialysis includes a finger restraint part and a palm fixing part, wherein the finger restraint part includes finger sleeves 1 for fixing five fingers and a connecting piece 2 arranged between the finger sleeves 1, and the connecting piece 2 is connected to the finger sleeves 1 through a rotating shaft 7; the palm fixing part is composed of a connecting rod, a fixing ring, and a fixing rope 5, and the connecting rod connects the finger restraint part and the fixing ring, and the fixing rope 5 runs through the fixing ring to fix the protective belt. In order to fix the entire hand to a certain place, an elastic band 6 with an adjustable length is also provided on the connecting rod, and the elastic band 6 can be tied to a bed or other fixed objects.

[0023] The end of the finger cuff 1 of the finger restraint part facing the palm is located at the metacarpophalangeal joint. The length of the finger cuff 1 is such that it can cover all corresponding finger joints. The end of the finger cuff 1 facing the fingertip is open, so that the finger can be extended from the opening, which is convenient for medical staff to observe the blood return of the fingertip, clamp the blood oxygen saturation clamp and other treatment and nursing activities. Preferably, the finger cuff 1 and the connecting piece 2 are made of hard materials to limit the bending of the fingers to the greatest extent. A rotating shaft 7 is provided between the finger cuff 1 and the connecting piece 2, which limits the movement of the fingers together, pinching, and making a fist, while allowing the fingers to move relatively within a small range, meeting ergonomics, avoiding the problems of muscle tension and metacarpophalangeal joint stiffness caused by the palm and fingers being in a fixed and extended state for a long time, and improving the comfort of the patient.

[0024] The connecting rod of the palm fixing part includes a first connecting rod 31 and a second connecting rod 32, and the fixing ring includes a first C-shaped semi-ring 41 and a second C-shaped semi-ring 42 with openings arranged opposite to each other. One end of the first connecting rod 31 is fixed to the outside of the thumb sleeve, and the other end is fixed to the middle part of the first C-shaped semi-ring 41; one end of the second connecting rod 32 is fixed to the outside of the little finger sleeve, and the other end is fixed to the middle part of the second C-shaped semi-ring 42; the fixing rope 5 connects the first C-shaped semi-ring 41 and the second C-shaped semi-ring 42 and can bind and fix the palm fixing part to the wrist. Specifically, the fixing rope 5 is divided into two parts, one part connects one group of oppositely arranged open ends of the two C-shaped semi-rings, and the other part is fixed to the other group of oppositely arranged open ends of the two C-shaped semi-rings, and is in an openable and closable state, such as Figure 1 , 2 As shown, in this embodiment, there are two rope ends that can be tied. Of course, it can also be designed as a rope end with a buckle in the prior art, and the rope end of the fixed rope 5 can be opened and closed by the buckle. The fixed ring and the fixed rope 5 form a closed ring structure to fix the palm fixing part at the wrist, and the finger restraining part and the palm fixing part are connected by a connecting rod, so as to achieve the fixation of the finger restraining part. Preferably, the connecting rod and the fixed ring are both made of hard materials, which can enhance the restraining force. Since the fixed ring is made of hard material, even if there is a certain gap between the fixed ring and the wrist, the palm fixing part will not easily fall off from the wrist, thereby avoiding the problem of tightening the wrist with a bandage in the prior art and then compressing the hemodialysis puncture site near the wrist. At this time, the back of the hand and the palm are not covered and are completely exposed, which is convenient for the implementation of various treatment methods, such as intravenous infusion therapy, and has good air permeability. At the same time, the two-part C-shaped half ring can realize the direct restraint and removal of the protective belt, which is convenient for medical staff to operate.

[0025] The length of the elastic band 6 is adjustable. Specifically, a length adjustment buckle (not shown in the figure) can be provided on the elastic band 6. When the fixed object for fixing the hand is close to the patient, the elastic band 6 is adjusted to be shorter for binding and fixing. When the fixed object is far away from the patient, the elastic band 6 needs to be adjusted to be longer for binding and fixing, thereby meeting the needs of different treatment methods.

[0026] When using this embodiment, it can be used in pairs according to treatment needs, and there is no need to distinguish between the left and right hands, that is, it can be used on both the left and right hands. First, the patient's fingers are placed in each finger cuff respectively, and the two parts of the fixing ring are located on the left and right sides of the wrist, and the fixing rope 5 is tied and fixed. When used on the hand on the side that has not undergone hemodialysis puncture, the back of the hand is completely exposed for intravenous infusion and other treatments. After the elastic bandage 6 is adjusted to a suitable length, it is tied to the bed or other fixed objects, thereby fixing the entire hand.
