Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary arm support for blood collection. Background Technology

[0002] Currently, the most common blood collection method involves medical staff manually collecting blood using a lancet. During this process, the patient typically places their arm on a blood collection pillow or pad. These pillows or pads are usually flat and simple. However, during blood collection, the upper arm and forearm must be in a straight line to fully expose the collection site. Existing blood collection pads cannot support the upper arm and forearm in a straight line, resulting in insufficient exposure of the collection site. Furthermore, the upper arm is often suspended in the air, leading to insufficient stability. Therefore, we propose an auxiliary arm support for blood collection to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing an auxiliary arm support for blood collection.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an auxiliary arm support for blood collection, comprising: an arm support, an upper arm portion, a forearm portion, a Velcro surface, an anti-slip strip, a protective pad, a Velcro hook surface, and a wrist pad. The upper arm portion is located on the left side of the upper surface of the arm support, and the forearm portion is located on the right side of the upper surface of the arm support. Velcro surfaces are fixedly installed on both sides of the upper surface of the arm support, and anti-slip strips are fixedly installed on both sides of the upper surface of the arm support. A protective pad is movably installed on the upper surface of the arm support, and Velcro hook surfaces are fixedly installed on both sides of the lower surface of the arm support. A wrist pad is fixedly installed on the right side of the upper surface of the protective pad.

[0005] Preferably, the upper arm portion is arranged in an inclined structure, and the forearm portion is arranged in a planar structure.

[0006] Preferably, the wrist pad is configured in a semi-circular shape.

[0007] Preferably, the protective pad is made of sponge material.

[0008] Preferably, the protective pad is adapted to the upper surface of the armrest, and the hook and loop sides of the Velcro correspond one-to-one.

[0009] Preferably, the anti-slip strips are distributed in an equidistant pattern.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] (1) The upper arm can be used to position the patient's elbow joint, so that the inclined upper arm can fit against the patient's upper arm and support the upper arm, thereby preventing the upper arm from hanging in the air and improving the stability of the arm. At the same time, the flat forearm can support the patient's forearm. Thus, by supporting the patient's arm with the upper arm and forearm, the patient's upper arm and forearm can be in a straight line, which can fully expose the blood collection site. At the same time, the wrist pad can support the patient's forearm wrist, so that the wrist is suspended in the air, making it easier for medical staff to hold the wrist.

[0012] (2) The armrest is more comfortable when the arm is placed on the protective pad made of sponge material; and the hook and loop sides of the Velcro are glued to each other, making it easy to attach and detach the protective pad and the armrest, and making it easy to disinfect and replace the protective pad.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figure 1-4 The illustrated auxiliary arm support for blood collection includes: arm support 1, upper arm 2, forearm 3, Velcro surface 4, anti-slip strip 5, protective pad 6, Velcro hook surface 7, and wrist pad 8. The upper arm 2 is located on the left side of the upper surface of arm support 1, and the forearm 3 is located on the right side of the upper surface of arm support 1. Velcro surfaces 4 are fixedly installed on both sides of the upper surface of arm support 1. Anti-slip strip 5 is fixedly installed on both sides of the upper surface of arm support 1. Protective pad 6 is movably installed on the upper surface of arm support 1. Velcro hook surfaces 7 are fixedly installed on both sides of the lower surface of arm support 1. Wrist pad 8 is fixedly installed on the right side of the upper surface of protective pad 6.

[0020] In this embodiment, the upper arm portion 2 is arranged in an inclined structure, and the forearm portion 3 is arranged in a planar structure.

[0021] In practical use, the upper arm portion 2 can be used to position the patient's elbow joint, allowing the inclined upper arm portion 2 to fit snugly against the patient's upper arm and provide support, thus preventing the upper arm from dangling and improving the stability of the arm position. At the same time, the flat forearm portion 3 can support the patient's forearm. Thus, by supporting the patient's arm with the upper arm portion 2 and the forearm portion 3, the patient's upper arm and forearm can be aligned in a straight line, allowing for full exposure of the blood collection site.

[0022] In this embodiment, the wrist pad 8 is arranged in a semi-circular structure.

[0023] In practical use, the wrist pad 8 can support the patient's forearm and wrist, allowing the wrist to be suspended in the air, making it easier for medical staff to hold the wrist.

[0024] In this embodiment, the protective pad 6 is made of sponge material.

[0025] In practical use, the protective pad 6 made of sponge material can improve the comfort of the armrest 1, making it more comfortable to place the arm on the protective pad 6.

[0026] In this embodiment, the protective pad 6 is adapted to the upper surface of the armrest 1, and the hook and loop side 4 and the hook and loop side 7 are in one-to-one correspondence.

[0027] In practical use, the hook and loop sides 4 and 7 of the Velcro are attached to each other, making it easy to attach and detach the protective pad 6 and the armrest 1, and making it easy to disinfect and replace the protective pad 6.

[0028] In this embodiment, the anti-slip strips 5 are arranged in an equidistant structure.

[0029] In practical use, the anti-slip strip 5 can increase the friction of the bottom of the arm support 1, making it less likely to slide when the bottom of the arm support 1 is placed on a flat surface, thus improving the stability of the placement.

[0030] The working principle of the auxiliary armrest for blood collection mentioned in this utility model:

[0031] During use, the upper arm 2 can be used to position the patient's elbow joint, so that the inclined upper arm 2 can fit against the patient's upper arm and support it, thereby preventing the upper arm from hanging in the air and improving the stability of the arm. At the same time, the flat forearm 3 can support the patient's forearm. Thus, by supporting the patient's arm with the upper arm 2 and forearm 3, the patient's upper arm and forearm can be in a straight line, which can fully expose the blood collection site.

[0032] At the same time, the wrist pad 8 can support the patient's forearm and wrist, allowing the wrist to be suspended in the air, making it easier for medical staff to hold the wrist.

[0033] Meanwhile, the protective pad 6 made of sponge material can improve the comfort of the armrest 1, making it more comfortable to place the arm on the protective pad 6; and the hook and loop sides 4 and 7 of the Velcro are attached to each other, making it easy to attach and detach the protective pad 6 from the armrest 1, and making it easy to disinfect and replace the protective pad 6.

[0034] Meanwhile, the anti-slip strip 5 can increase the friction at the bottom of the arm support 1, making it less likely to slide when the bottom of the arm support 1 is placed on a flat surface, thus improving the stability of the placement.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
