Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to an auxiliary pillow for radial artery puncture that can be pressed to stop bleeding. Background Technology

[0002] In clinical practice, arterial blood gas analysis can accurately and quickly reflect the body's respiratory function and acid-base balance. Especially in the resuscitation of critically ill patients, it is the most reliable indicator and basis for judging respiratory failure. Because the radial artery is anatomically superficial and easy to access, only the forearm needs to be exposed during the operation, which is convenient for puncture. Therefore, the radial artery is often the first choice for arterial blood gas sampling.

[0003] However, in routine radial artery puncture procedures, medical staff often puncture the periosteum, which is rich in blood vessels and nerves. This area is highly sensitive to pain. At the same time, the radial artery is prone to slipping and has a weak pulsation, resulting in a low success rate for the first puncture. This increases patient suffering and reduces puncture efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problem that during routine radial artery puncture procedures, medical personnel often puncture the periosteum, which is rich in blood vessels and nerves and has high pain sensitivity. At the same time, the radial artery is prone to slippage and has a weak pulsation, resulting in a low success rate for the first puncture, increasing patient pain and reducing puncture efficiency. Therefore, this invention proposes a radial artery puncture auxiliary pillow that can be pressed to stop bleeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressable hemostatic radial artery puncture auxiliary pillow, comprising a cotton cover and a sponge block, wherein the outer surface of the cotton cover is provided with a first Velcro fastener, the first Velcro fastener is connected to the cotton cover by sewing, the outer surface shape of the sponge block is adapted to the inner shape of the cotton cover, the outer surface size of the sponge block is slightly larger than the inner size of the cotton cover, and the two ends of the sponge block have different bevel angles.

[0006] The aforementioned components achieve the following effects: When performing radial artery puncture on a patient, a cotton sheath is placed over the outer surface of the sponge block, with the inner wall of the sheath tightly fitted to the outer surface of the sponge block. The patient's wrist is positioned at the top of the sponge block, with the arm resting against the longer end of the sponge block and the back of the hand against the shorter side of the sponge block, passing through and grasping the first Velcro straps that hold the two ends together. The palm is in a hyperextended, arched position, which helps to tighten the patient's skin, straighten and fix the radial artery, and fully expose the radial artery, making the pulsation clearer. This improves the success rate of radial artery puncture for nurses in the department. Furthermore, the position restriction of the palm by the first Velcro strap eliminates the need for additional medical staff to fix the patient's arm, reducing medical costs.

[0007] Preferably, the top of the sponge block has a slot, and a hollow tube is slidably inserted into the slot, with a second Velcro strap inside the hollow tube.

[0008] The aforementioned components achieve the following effects: When using the auxiliary pillow, the hollow tube can be inserted into the slot at the top of the sponge block, and the second Velcro strap can be passed through the inside of the hollow tube. When the cotton cover is placed on the outer surface of the sponge block, the two ends of the second Velcro strap are passed through the two rectangular holes on both sides of the cotton cover, so that the sponge block is inside the cotton cover and the two ends of the second Velcro strap are outside the cotton cover. After the patient's arm is punctured with the aid of the auxiliary pillow, the hemostatic cotton swab is attached to the punctured skin, and the two ends of the second Velcro strap are glued together and pressed onto the cotton swab. The cotton swab is pressed for 5 to 10 minutes. The auxiliary cotton swab stops the bleeding at the punctured skin without the need to press the cotton swab with your hand, further improving the practicality of the auxiliary pillow.

[0009] Preferably, the first and second hook and loop fasteners are elastic Velcro.

[0010] The effect achieved by the above components is that by setting the first and second hook and loop fasteners to be elastic Velcro, the overall length of the first and second hook and loop fasteners can be adjusted in small intervals according to the thickness of the user's arm and wrist, thereby improving the adaptability of the auxiliary pillow when in use.

[0011] Preferably, the second Velcro fastener is not directly connected to the interior of the hollow tube.

[0012] The effect achieved by the above components is that when the second Velcro is pressed on the cotton swab, it is easy to pull the second Velcro and the hollow tube to move their positions, making it convenient for the patient to control the second Velcro with their left or right hand (i.e., one hand).

[0013] Preferably, the cotton cover is made of pure cotton material and sewn together.

[0014] The aforementioned components achieve the following effect: after the auxiliary pillow is used, the cotton cover can be removed and washed for easy reuse, further improving the convenience and flexibility of using the auxiliary pillow.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting a sponge block, when performing radial artery puncture on a patient, the patient's wrist joint is placed at the top of the sponge block, with the palm in a reverse arch and hyperextended position. This helps to tighten the patient's skin, straighten and fix the radial artery, and fully expose the radial artery, making the pulsation clearer. This improves the success rate of radial artery puncture for nurses in the department. After the puncture is completed, the second Velcro can be used to apply pressure to the hemostatic cotton swab.

[0022] Example 1, as Figure 1-4 As shown, a compressible radial artery puncture auxiliary pillow includes a cotton cover 1 and a sponge block 4. The outer surface of the cotton cover 1 is provided with a first Velcro 2, which is sewn to the cotton cover 1. The outer surface shape of the sponge block 4 is adapted to the inner shape of the cotton cover 1, and the outer surface size of the sponge block 4 is slightly larger than the inner size of the cotton cover 1. The two ends of the sponge block 4 have different bevel angles. When performing radial artery puncture on a patient, the cotton cover 1 is placed over the outer surface of the sponge block 4, ensuring a tight fit between the inner wall of the cotton cover 1 and the outer surface of the sponge block 4, allowing the patient's wrist to be punctured. The joint is placed at the top of the sponge block 4, the arm is attached to the longer end of the sponge block 4, and the back of the hand is attached to the shorter side of the sponge block 4, passing through and grasping the first Velcro 2 at both ends. The palm is in a reverse arch and hyperextended position, which helps to tighten the patient's skin, straighten and fix the radial artery, and fully expose the radial artery, making the pulsation clearer. This improves the success rate of radial artery puncture for nurses in the department. Moreover, by restricting the position of the palm through the first Velcro 2, no additional medical staff are needed to fix the patient's arm, reducing medical costs.

A second Velcro 7 is provided inside the hollow tube 6. When using the auxiliary pillow, the hollow tube 6 can be locked in the slot 5 at the top of the sponge block 4, and then the second Velcro 7 is passed through the inside of the hollow tube 6. When the cotton cover 1 is put on the outer surface of the sponge block 4, the two ends of the second Velcro 7 are passed through the two rectangular holes 3 on both sides of the cotton cover 1, so that the sponge block 4 is inside the cotton cover 1 and the two ends of the second Velcro 7 are outside the cotton cover 1. After the patient's arm is punctured with the help of the auxiliary pillow, the hemostatic cotton swab is attached to the punctured skin, and the two ends of the second Velcro 7 are glued and pressed on the cotton swab. The cotton swab is pressed for 5 to 10 minutes. The auxiliary cotton swab stops the bleeding at the punctured skin without the need to press the cotton swab by hand, which further improves the practicality of the auxiliary pillow.

[0024] Reference Figure 1-4 As shown in this embodiment: the first Velcro 2 and the second Velcro 7 are elastic Velcro. By setting the first Velcro 2 and the second Velcro 7 to be elastic Velcro, the overall length of the first Velcro 2 and the second Velcro 7 can be adjusted slightly according to the thickness of the user's arm and wrist, improving the adaptability of the auxiliary pillow when used. The second Velcro 7 is not directly connected to the inside of the hollow tube 6. When the second Velcro 7 is used to press the cotton swab, the second Velcro 7 and the hollow tube 6 can be pulled to move their positions, making it convenient for the patient to control the second Velcro 7 with their left or right hand (i.e., one hand). The cotton cover 1 is made of pure cotton material. After the auxiliary pillow is used, the cotton cover 1 can be removed and washed for reuse, further improving the convenience and flexibility of using the auxiliary pillow.

[0025] Reference Figure 1-4 As shown in this embodiment, the material, manufacturing, and application data of the auxiliary pillow as a whole are as follows:

[0027] (2). Production: Cut one side of the high-density sponge into a 55° bevel to form a trapezoid with a top edge of 22 cm, a bottom edge of 20 cm, and a height of 5 cm. Make a trapezoidal cotton cover from cotton fabric, sew the first Velcro closure onto the bevel side, insert a hollow tube into the groove at the highest point of the sponge block's slope, and thread the second Velcro closure into the hollow tube.

[0028] (3). Application data: From March to September 2023, 450 patients aged 16 to 95 years with an average age of 63 years were hospitalized in our department and underwent arterial blood gas analysis. All patients used a radial artery puncture auxiliary pillow that can be pressed to stop bleeding. The puncture was successful in 422 cases (93.9%).

[0029] Working principle: When performing radial artery puncture on a patient with the aid of the pillow, first, the hollow tube 6 is inserted into the slot 5 at the top of the sponge block 4. Then, the second Velcro 7 is passed through the inside of the hollow tube 6. When the cotton sleeve 1 is placed on the outer surface of the sponge block 4, the two ends of the second Velcro 7 are passed through the two rectangular holes 3 on both sides of the cotton sleeve 1, so that the sponge block 4 is inside the cotton sleeve 1 and the two ends of the second Velcro 7 are on the outside of the cotton sleeve 1. This allows the patient's wrist joint to be placed at the top of the sponge block 4, with the arm against the longer end of the sponge block 4 and the back of the hand... The first Velcro 2 is attached to the shorter side of the sponge block 4 and passed through it. The palm is in a reverse arch and hyperextended position to help tighten the patient's skin and straighten and fix the radial artery. After the puncture, the hemostatic cotton swab is attached to the puncture site. The two ends of the second Velcro 7 are glued together and pressed onto the cotton swab. The cotton swab is pressed for 5-10 minutes to help stop the bleeding at the puncture site. After the bleeding is stopped, the second Velcro 7 is opened. After the auxiliary pillow is used, the cotton cover 1 can be removed and cleaned for reuse.
