Description

A restraint device for protecting arteriovenous fistula catheter

technical field

The invention relates to the field of clinical nursing appliances, in particular to a restraint device for protecting an arteriovenous fistula catheter.

Background technique

Clinically, restraint belts and anti-extubation gloves are commonly used to restrain the patient's wrist to stabilize and prevent patients from extubating themselves. However, for patients with arteriovenous fistula, it is not enough to just keep the wrist fixed. It is not enough to provide sufficient blood for hemodialysis treatment and guarantee the adequacy of dialysis treatment. It is also necessary to ensure that the dorsiflexion of the hand reaches a certain angle to avoid restlessness of the patient's hand , to successfully complete the treatment.

To sum up, the prior art lacks a restraint device for patients with arteriovenous fistula to keep the dorsiflexion of the hand and avoid restlessness of the hand.

Contents of the invention

The invention provides a restraint device for protecting an arteriovenous fistula catheter, which can keep the dorsiflexion of the patient's hand, avoid the adverse effect of the patient's hand movement on the treatment, and effectively prevent the patient from extubating the tube automatically.

To achieve the above object, the present invention adopts the following technical solutions:

A restraint device for protecting an arteriovenous fistula catheter, comprising: a glove (1), a palm restriction block (4), a fixing belt (6), a sliding Velcro (8), and the glove (1) has an opening at the front end and is equipped with a sliding Velcro (8), the glove (1) contains a palm restriction block (4), the patient puts his hand into the glove, and holds the palm restriction block (4), which can prevent the deformity of flexion, thumb adduction and flexion, and at the same time To prevent the patient from grasping gas objects, the palm restriction block (4) restricts the patient's hand to maintain a posture of dorsiflexion of 15°-30°, and the fixing belt (6) is fixed on the periphery of the glove (1) along the direction perpendicular to the hand , to prevent the patient's hand and palm restraining block (4) from detaching.

Further, the shape of the palm restriction block (4) is spherical, ellipsoidal, or an inverted mold made according to the space of the patient's palm.

Further, the rear end of the glove (1) is connected with an arm limiting device, and the arm limiting device extends from the back of the patient's hand to the elbow.

Further, the glove (1) includes a palm surface and a palm surface, and a tension sponge (2) is installed on the inner side of the back of the hand to relieve the discomfort caused by the arm limit device pressing on the back of the hand.

Further, the arm limiting device is a sleeve structure customized according to the shape of the patient's arm.

Further, the arm limiting device includes a first fixed plate (5), a second fixed plate (7), and a restraint belt (3). The first fixed plate (5) covers the outer side of the back of the hand, and the second fixed plate (7) covers On the outer side of the forearm, the restraint belt (3) is fixed on the outer side of the second fixing plate (7) along the direction perpendicular to the arm.

Further, the restraint belt (3) includes three pieces, which are integrally formed to disperse the restraint force required to fix the arm and enhance the comfort of the patient.

Further, the restraint belt (3) and the fixing belt (6) are made of medical adhesive tape or Velcro straps.

Further, the sliding velcro (8) has a mesh structure, which is convenient for observing the blood supply at the end and measuring the blood sugar at the end.

The beneficial effect of the present invention is that it is suitable for patients with arteriovenous fistula who need to keep their hand posture for a long time. In the prior art, the patient's hand can only be limited in a certain space through the glove, and the patient is in the glove space. , will still produce deformities such as flexion and thumb adduction and flexion, which will affect the patency of the arteriovenous fistula catheter. The present invention limits the patient's hand posture through the palm restriction block. When the patient holds the palm restriction block, the hand The dorsiflexion of 15°-30° is naturally formed on the lower part, and then through the gloves and the fixing belt, the activity space of the patient's hand is further restricted, and the restriction block of the patient's hand and palm is prevented from detaching, effectively restraining restless patients and ensuring treatment went smoothly.

detailed description

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

An embodiment of the present invention provides a restraint device for protecting an arteriovenous fistula catheter, as shown in FIG. 6. The second fixing plate 7. The sliding Velcro 8.

A palm restriction block 4 is arranged inside the glove 1, and the palm restriction block 4 is spherical. The patient puts his hand into the glove 1 and holds the palm restriction block 4 in the palm of his hand. The glove 1 is divided into two pieces, the back of the hand and the palm of the hand. The front end of the glove 1 is open, and a sliding Velcro 8 is installed. The inner side of the back of the hand of the glove 1 is also equipped with a first fixed plate 5 and a tension sponge 2, and the tension sponge 2 is close to the back of the hand of the patient, buffering the discomfort that the first fixed plate 5 directly contacts the back of the hand. The glove 1 surface is also sewed with a fixed belt 6, the fixed belt 6 adopts Velcro straps, and the fixed belt 6 is glued along the direction perpendicular to the palm, so that the patient's hand and the palm limiting block 4 are fixed to prevent the palm limiting block 4 from breaking away.

After the patient puts on the glove 1, the glove 1 also extends along the direction of the patient's arm and installs a second fixing plate 5 for fixing the patient's forearm and wrist joint. Velcro straps are used, connected sequentially, and integrally formed. The three restraint straps 3 disperse the necessary restraint force to fix the patient's arm, enhance the patient's comfort, and avoid the oppression of the patient's arteriovenous fistula catheter.

In sum, the beneficial effects of the present invention are:

It is suitable for patients with arteriovenous fistula catheter, keeping the dorsiflexion of the patient's hand at 15°-30°, effectively restraining restless patients, and ensuring the smooth progress of treatment;

By dispersing the binding force, it avoids the excessive restraint of the patient's wrist by the existing restraint belt, and protects the patient's fragile arteriovenous fistula catheter;

The opening design of the glove is convenient for the observation of blood supply in the extremities and the monitoring of blood sugar.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. All should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
