Description

Technical Field

[0001] This utility model relates to the field of human necessities, and in particular to medical auxiliary equipment, especially a restraint glove for protecting the radial artery puncture site. Background Technology

[0002] Radial artery puncture and catheterization is a common invasive procedure in clinical practice, used to accurately monitor blood pressure and collect blood frequently. Compared to large arteries such as the femoral artery and brachial artery, the radial artery is relatively small, so radial artery catheters are prone to dislodgement. If the radial artery catheter dislodges, the patient will face serious risks of bleeding and infection.

[0003] To prevent radial artery catheter dislodgement, patients are usually fitted with restraint gloves to restrict hand movement. Commonly used restraint gloves are flat and contain the patient's palm to wrist for restraint. However, these gloves have the following drawbacks:

[0004] Because the human wrist joint is flexible, patients can still rotate their wrists even when their palms are restricted. This can cause the radial artery catheter at the wrist to rub against the restraint glove, leading to catheter dislodgement. Furthermore, ordinary restraint gloves typically use straps to secure the glove at the wrist, very close to the radial artery catheter, easily causing interference. If the straps are too loose, they won't provide effective restraint; if they are too tight, they can compress the radial artery catheter, leading to dislodgement or bleeding. The restraint at the wrist significantly impacts the radial artery puncture site. For example, CN212140696U discloses a restraintable radial artery fixation glove that uses restraint straps connected to both sides of the wrist for fixation. However, these wrist straps are highly susceptible to rubbing against the radial artery catheter, causing it to dislodge.

[0005] Hand protective gloves can obscure the radial artery puncture site, making it impossible to observe radial artery bleeding and difficult to access the radial artery for catheter placement after bleeding occurs. For example, CN218572393U discloses a restraint glove that is fixed to the patient's hand with a wrist strap, obscuring the radial artery puncture site and making observation difficult.

[0006] Prolonged restriction of hand movement can lead to poor blood circulation and cold fingers. Summary of the Invention

[0007] The purpose of this utility model is to provide a restraint glove to protect the radial artery puncture site. The restraint glove is intended to solve the technical problems in the prior art, such as the friction between the radial artery catheter and the restraint glove, difficulty in observing the radial artery puncture position, and poor blood flow in the patient's hand.

[0008] A restraint glove for protecting the radial artery puncture site includes a hand protective sleeve and an arm restraint sleeve. A first fixing ring is provided at the opening edge of the hand protective sleeve, and a second fixing ring is provided at the opening edge of one end of the arm restraint sleeve. The first and second fixing rings are connected to each other by one or more connectors, and a gap is provided between the first and second fixing rings. Each connector includes an arc-shaped strip and two straight strips, with the two straight strips respectively located at both ends of the arc-shaped strip. Each straight strip has a mounting hole, and the straight strips at both ends are riveted to the first and second fixing rings by passing through the corresponding mounting holes. The concave side of the arc-shaped strip faces the axis of the arm restraint sleeve. Two or more straps are arranged around the outer periphery of the arm restraint sleeve, including one or more binding straps, one end of which is fixed to the arm restraint sleeve or the second fixing ring.

[0009] Furthermore, the hand protector is provided with a partition cloth inside, which divides the interior of the hand protector into upper and lower layers, with the upper layer communicating with the opening of the hand protector; a strip-shaped notch is provided on the bottom surface of the hand protector, which communicates with the lower layer inside the hand protector; a heating pack is provided in the lower layer inside the hand protector.

[0010] Furthermore, the top surface of the hand protector is provided with an observation opening, and an observation window is provided on the observation opening. One side of the observation window is fixedly connected to the shell of the hand protector, and the bottom surface of the other side of the observation window is detachably connected to the shell of the hand protector by Velcro.

[0011] Furthermore, the bottom surface of the hand protector is covered with an anti-slip pad.

[0012] The working principle of this utility model:

[0013] After being put on, the patient's radial artery puncture site is located precisely between the first and second fixing rings, that is, in the gap between the hand protective sleeve and the arm restraint sleeve. The concave side of the connector's arc faces inward, thus preventing the patient's radial artery puncture site from contacting any object. Even if the wrist is rotated, it will not rub against the restraint glove, preventing the radial artery catheter from falling off.

[0014] Then, tie three straps in sequence to secure the arm restraint tube to the patient's arm, keeping the straps away from the patient's wrist to avoid affecting the radial artery puncture site.

[0015] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0016] This utility model relates to a hand protective sleeve and an arm restraint sleeve connected by an arc-shaped connector. A gap is provided between the hand protective sleeve and the arm restraint sleeve, within which the radial artery catheter is placed. The concave side of the arc-shaped connector faces inward away from the wrist, thus preventing rubbing between the radial artery catheter and the restraint glove. The patient's arm is restrained by a strap around the outer periphery of the arm restraint sleeve, with the restraint position away from the wrist to avoid the strap interfering with the radial artery catheter at the wrist.

[0017] This utility model allows for good observation of bleeding at the radial artery puncture site through the gap between the hand protective sleeve and the arm restraint tube, and also facilitates direct radial artery catheterization.

[0018] The hand protector of this utility model has a double-layer structure. The patient's hand is placed on the upper layer, and a heating pack is set in the lower layer to prevent the patient's fingers from getting cold. Attached Figure Description

[0024] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention. Example

[0025] like Figures 1 to 2As shown, this embodiment provides a restraint glove for protecting the radial artery puncture site, including a hand protective sleeve 1 and an arm restraint tube 2. The hand protective sleeve 1 is disc-shaped with an opening on one side. A first fixing ring 101 is fixedly connected to the opening edge of the hand protective sleeve 1. A second fixing ring 201 is fixedly connected to the opening edge of one end of the arm restraint tube 2. Both the first fixing ring 101 and the second fixing ring 201 are made of plastic. The first fixing ring 101 and the second fixing ring 201 are coaxially connected by four evenly distributed connectors 3. After connection, there is a certain gap between the first fixing ring 101 and the second fixing ring 201. This gap is located at the radial artery puncture site on the patient's wrist, preventing the radial artery puncture site from contacting objects. At the same time, the bleeding situation at the radial artery puncture site can be well observed through this gap, and it is also convenient to directly perform radial artery catheterization.

[0026] The connector 3 is handle-shaped and includes an arc-shaped strip 301 and two straight strips 302. The two straight strips 302 are fixed to both ends of the arc-shaped strip 301. Each straight strip 302 has a mounting hole 303. The straight strips 302 at both ends are riveted to the first fixing ring 101 and the second fixing ring 201 by passing through the corresponding mounting holes 303, thereby connecting the first fixing ring 101 and the second fixing ring 201 together. The concave side of the arc-shaped strip 301 faces the axis of the arm restraint cylinder 2, thereby further moving the connector 3 away from the radial artery puncture site of the patient's wrist, avoiding contact between the connector 3 and the radial artery catheter of the patient's wrist, which could cause the radial artery catheter to fall off.

[0027] The diameter of the arm restraint tube 2 is larger than the circumference of the patient's arm. Three straps 4 are arranged around the outer periphery of the arm restraint tube 2. The structure of the straps 4 is similar to that of a common waist belt. The middle section of the straps 4 is fixed to the arm restraint tube 2. One end of the straps 4 is a metal buckle, and the other end of the straps 4 has several buckle holes. The straps are fixed by inserting the pins of the metal buckle into the buckle holes. The connection method is the same as that of a waist belt, and will not be described in detail here. In other embodiments, the straps 4 can also be Velcro, buckles, or other connection methods. The three straps 4 are wrapped around different positions of the arm to fix the arm restraint tube 2 to the arm.

[0028] It also includes one or more straps 9, one end of which is fixed to the arm restraint tube 2 or the second fixing ring 201, and the other end of which is tied to a fixed object such as a hospital bed, so as to achieve the effect of connecting the arm restraint tube 2 to the fixed object such as the hospital bed and restricting the range of motion of the patient's arm.

[0029] The top surface of the hand protective sleeve 1 has an observation opening, and an observation window 5 is provided on the observation opening. One side of the observation window 5 is fixedly connected to the shell of the hand protective sleeve 1, and the bottom surface of the other side of the observation window 5 is detachably connected to the shell of the hand protective sleeve 1 by Velcro. The observation opening can be exposed by lifting the observation window 5, which makes it convenient to observe the condition of the patient's hand, or to put a finger pulse oximeter on the patient through the observation opening.

[0030] How to use this embodiment:

[0031] The patient's hand passes through the arm restraint sleeve 2, the second fixing ring 201, and the first fixing ring 101 in sequence and is then placed in the hand protective sleeve 1. At this time, the patient's radial artery puncture site is located between the first fixing ring 101 and the second fixing ring 201, that is, in the gap between the hand protective sleeve 1 and the arm restraint sleeve 2. The concave side of the arc-shaped connector 3 faces inward, thereby preventing the patient's radial artery puncture site from contacting objects. Even if the wrist is rotated, it will not scratch the restraint glove, thus preventing the radial artery catheter from falling out.

[0032] Then, tie three straps 4 in sequence and tie the arm restraint tube 2 to the patient's arm. The straps should be placed away from the patient's wrist to avoid affecting the radial artery puncture site.

[0033] After wearing it, you can open the observation window 5 to observe the condition of the patient's hand through the observation port to avoid poor blood circulation, or you can wear a finger pulse oximeter on the patient's finger through the observation port for monitoring. Example

[0034] like Figures 3 to 4 As shown, this embodiment is a preferred solution of Embodiment 1, providing a restraint glove for protecting the radial artery puncture site. A layer of separator fabric 102 is horizontally fixed inside the hand protective sleeve 1. The separator fabric 102 is a breathable fabric that divides the interior of the hand protective sleeve 1 into upper and lower layers. The upper layer is connected to the opening of the hand protective sleeve 1. After the patient's hand enters the opening of the hand protective sleeve 1, it is placed in the upper layer of the hand protective sleeve 1.

[0035] The bottom surface of the hand protector 1 has a strip-shaped notch 8, which is connected to the lower layer inside the hand protector 1. A heating pack 6 can be placed inside the lower layer of the hand protector 1 through the strip-shaped notch 8. The heating pack 6 can be a commonly used "heat pack" heating patch. The heating pack 6 provides heat to the upper layer through the partition cloth 102 to prevent the patient's fingers from getting cold. At the same time, the partition cloth 102 protects the patient's hand in the upper layer from being too close to the heating pack 6, which could cause burns.

[0036] The bottom surface of the hand protective sleeve 1 is covered with an anti-slip pad 7. After the anti-slip pad 7 comes into contact with the bed, it can limit the patient's hand from sliding back and forth on the bed through friction, thus preventing the radial artery catheter from falling off due to the hand sliding back and forth.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
