Abstract
Description
Technical Field
[0001] This application relates to the field of arterial puncture technology, specifically to a radial artery puncture fixation device and a radial artery puncture treatment bed. Background Technology
[0002] Radial artery puncture is a procedure that bridges medical and surgical treatments and is a relatively new discipline. It belongs to interventional therapy, along with femoral artery puncture and carotid artery puncture. Arterial puncture and catheterization involves real-time monitoring of the patient's blood pressure via an invasive arterial catheter, facilitating timely adjustment of vasoactive drug dosages, maintaining hemodynamic stability, and conveniently obtaining arterial blood for blood gas analysis. Therefore, it is one of the most common procedures in the intensive care unit. The radial artery is superficial and shares blood supply to the hand with the ulnar artery, resulting in a relatively low probability of complications, making it the preferred site for arterial puncture and catheterization. Because bending or moving the patient's wrist during the puncture may cause the radial artery to not be fully extended, hindering the procedure, many hospitals often use a simple long board to support the patient's armpit, allowing the arm to be straightened on the board before performing the radial artery puncture.
[0003] However, the conventional method of using a longboard to assist in stretching the patient's arm for radial artery puncture cannot accommodate patients with different arm lengths. For example, some younger patients have an arm length that is only half that of an adult patient, so the longboard cannot be used and the nurse must manually straighten and fix the patient's arm, making the surgery more difficult. To solve this problem, telescopic longboards are now commonly used. The telescopic structure changes the length of the longboard to accommodate different patients' arm lengths.
[0004] However, telescopic structures are generally quite complex and inevitably contain many structural gaps. When a patient's blood gets on the telescopic structure, the blood may seep into the gaps as the structure moves, or even into the inside of the telescopic sleeve, making it difficult to clean. If the blood is not cleaned properly, it may pose a medical risk to patients who use the device later.
[0005] Therefore, it is particularly important to design a radial artery puncture fixation device that can be adapted to patients with different arm lengths and has a simple structure that is easy to clean. Utility Model Content
[0006] In view of the above problems, this application provides a radial artery puncture fixation device to solve the problem of the high difficulty in stretching and fixing the arms of patients with different arm lengths during radial artery puncture.
[0007] According to one aspect of the embodiments of this application, a radial artery puncture and fixation device is provided. The radial artery puncture and fixation device includes: a first support member and a second support member, one end of the first support member and one end of the second support member being rotatably connected so that the first support member and the second support member are set at an angle to each other; a fixing arch is provided on the second support member, the fixing arch is used to fix the patient's hand so that when the two support members rotate, they drive the patient's hand to rotate so that the patient's arm and hand are placed at an angle; the first support member includes a first folded portion and a second folded portion, the first folded portion and the second folded portion being rotatably connected, when the first folded portion rotates to overlap with the second folded portion, the first support member has a first length, when the first folded portion rotates to be located on the same plane as the second folded portion, the first support member has a second length, the second length being greater than the first length.
[0008] In one alternative approach, the fixing arch is made of rubber.
[0009] In one alternative embodiment, the first support member is a long plate-shaped structure, and an abutment portion is provided at the end of the first support member away from the second support member. The projected area of the abutment portion on a plane perpendicular to the first support member is larger than the projected area of the first support member.
[0010] In one alternative embodiment, the first support member has a fixing groove, the depth of which is set from deep to shallow from the end of the first support member connected to the second support member toward the end of the first support member away from the second support member. The fixing groove is used to allow a user's arm to be inserted to restrict the movement of the user's arm.
[0011] In one alternative embodiment, the first support member includes a body portion and a telescopic portion, which are connected by a movable guide rail so that the telescopic portion can switch between overlapping and extended states with the body portion, thereby changing the length of the first support member.
[0012] In one alternative embodiment, a clamping structure is provided at the end of the first support member away from the second support member. The clamping structure is controlled by bolts to clamp the device at the edge of the bed to fix the radial artery puncture fixation device at the edge of the bed.
[0013] In one alternative approach, the first support member is a double-layer structure.
[0014] According to another aspect of the embodiments of this application, a radial artery puncture treatment bed is provided, characterized in that it includes a treatment bed body and a radial artery puncture fixation device as described above, wherein one side of the treatment bed body has a connecting portion for connecting the radial artery puncture fixation device, so that the radial artery puncture fixation device and the treatment bed body are fixedly connected to each other.
[0015] By setting a first support member and a second support member that can rotate relative to each other at an angle, and by setting a fixing arch on both the first and second support members, the patient's arm and wrist can be fixed to the first and second support members by the fixing arch. When the first and second support members rotate relative to each other at an angle, the patient's arm can be bent, achieving a straightening effect on the radial artery. By setting a foldable first support member, the length of the first support member can be changed in two stages, improving the adaptability of this embodiment to patients with different arm lengths. When the target patient is an adult with a longer arm length... When the target patient is an adult, the first folding part can be rotated to be on the same plane as the second folding part, so that the length of the first support can meet the arm length requirements of the adult. When the target patient is a child with a shorter arm length, the length of the first support can be shortened by rotating the first folding part to overlap with the second folding part, so that the first support can meet the arm length requirements of the child patient. This facilitates the medical staff to perform puncture surgery and improves the adaptability of puncture surgery for patients with different arm lengths. At the same time, the folding structure is relatively simple and has a large exposed area, which makes it easy to clean the blood that has been contaminated after the operation.

In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, specific embodiments of this application are given below.

[0044] Arterial puncture is widely used in various treatments, examinations, and tests, and is an essential clinical procedure. The radial artery has a relatively small diameter and is one of the most easily spasmed muscular blood vessels in the human body. Therefore, radial artery puncture is very prone to failure due to the inability to puncture the blood vessel and repeated stimulation causing arterial spasm.
[0045] The inventors have noticed that there is often a large difference in arm length among patients of different ages. For example, the arm length of a young patient may be only half that of an adult patient. In order to adapt to the arm length of different patients, it is necessary to use an adjustable support plate to support the patient's arm so that medical staff can stretch the patient's arm to perform surgery.
[0046] However, during radial artery puncture surgery, blood may leak or splatter, easily contaminating the fixation plate. If a common telescopic structure is applied to the fixation plate of radial artery puncture to achieve telescopic length adjustment to accommodate patients with different arm lengths, the blood contaminated on the fixation plate can easily seep into the interior through the gaps of the telescopic device, making it difficult to clean. Thorough cleaning often requires disassembling the telescopic device, which is a cumbersome process. Failure to clean it can pose medical risks to subsequent patients.
[0047] To solve the aforementioned technical problems, the inventors of this application, through research, designed a radial artery puncture and fixation device, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 and Figure 2 This is a three-dimensional structural diagram of the radial artery puncture and fixation device 100 provided in the embodiments of this application. Figure 3 , Figure 4 and Figure 5 This is a side view of the radial artery puncture fixation device provided in an embodiment of this application when folded. Figures 1 to 5As shown, one embodiment of this application provides a radial artery puncture fixation device 100, including: a first support member 110 and a second support member 120. One end of the first support member 110 is rotatably connected to one end of the second support member 120 so that the first support member 110 and the second support member 120 are set at an angle to each other. A fixing arch 121 is provided on the second support member 120, which is used to fix the patient's hand so that when the two supports rotate, the patient's hand rotates so that the patient's arm and hand are placed at an angle. The first support member 110 includes a first folding part 116 and a second folding part 117, which are rotatably connected. When the first folding part 116 rotates to overlap with the second folding part 117, the first support member 110 has a first length. When the first folding part 116 rotates to be on the same plane as the second folding part 117, the first support member 110 has a second length, which is greater than the first length.
[0048] In radial artery puncture surgery, the patient's wrist needs to be bent to position the hand and arm at an angle to stretch the blood vessel and facilitate the procedure. Therefore, when the patient places their arm on the first support 110 and their hand on the second support 120, the hand is secured to the second support 120 by the fixing arch 121. The second support 120 rotates along the end connected to the first support 110, allowing the patient's hand and arm to be stretched at an angle, thus stretching the radial artery and ensuring a smooth puncture. This eliminates the need for medical staff to manually bend the patient's wrist, reducing surgical risks. Furthermore, the angle between the first support 110 and the second support 120 can be adjusted according to the patient's wrist flexibility, improving patient comfort.
[0049] By setting a foldable first support member 110, the length of the first support member 110 can be changed in two stages, which improves the adaptability of this embodiment to patients with different arm lengths. When the target patient is an adult with a long arm length, the first folding part 116 can be rotated to be on the same plane as the second folding part 117, so that the length of the first support member 110 can meet the arm length requirements of adults. When the target patient is a child with a short arm length, the length of the first support member 110 can be shortened by rotating the first folding part 116 to overlap with the second folding part 117, so that the first support member 110 can meet the arm length requirements of children.
[0050] Preferably, corresponding fixing devices can also be provided on the first folding portion 116 or the second folding portion 117, so that when the first folding portion 116 rotates to overlap with the second folding portion 117, a fixing effect can be achieved between the first folding portion 116 and the second folding portion 117, preventing accidental rotation of the first folding portion 116 or the second folding portion 117 from causing changes in the length of the first support member 110 during the operation. For example, the fixing device can be provided with a magnetic attraction point at one end of the first folding portion 116, so that when the first folding portion 116 overlaps with the second folding portion 117, the first folding portion 116 is fixed to the second folding portion 117 through the magnetic attraction point. The fixing device can also be any type of strap. Similarly, other fixing devices can be added to fix the first folding portion 116 and the second folding portion 117 in the same plane. The embodiments of this application do not impose special limitations on the implementation of the fixing method.
[0051] Furthermore, in order to improve the fixation effect on the patient's arm, such as Figure 1 and Figure 2 As shown, a fixing strap for binding the patient's arm can also be added to the first support member 110 to ensure that the patient's arm is firmly fixed to the first support member 110, which can improve the stretching effect.
[0052] Preferably, in order to make the adjustment of the rotation angle between the first support member 110 and the second support member 120 more convenient and effective, the rotatable connection between the first support member 110 and the second support member 120 can be a segmented snap-fit rotatable connection. That is, after the first support member 110 and the second support member 120 rotate relative to each other by a certain fixed angle, they can be fixed by the resistance of the snap-fit or the rotatable connection itself, so as to facilitate the adjustment operation of medical staff. The same applies to the first folding part 116 and the second folding part 117 of the first support member 110.
[0053] By setting a first support member 110 and a second support member 120 that can rotate relative to each other at an angle, and by setting a fixing arch 121 on both the first support member 110 and the second support member 120, the patient's arm and wrist can be fixed to the first support member 110 and the second support member 120 by the fixing arch 121. When the first support member 110 and the second support member 120 rotate relative to each other at an angle, the patient's arm can be bent, achieving a straightening effect on the radial artery. By setting a foldable first support member 110, the length of the first support member 110 can be changed in two stages, improving the adaptability of this embodiment to patients with different arm lengths. When the target patient is an adult with a longer arm length, the first fold 116 can be rotated to be on the same plane as the second fold 117, so that the length of the first support member 110 can meet the arm length requirements of the adult. When the target patient is a child with a shorter arm length, the length of the first support member 110 can be shortened by rotating the first fold 116 to overlap with the second fold 117, so that the first support member 110 can meet the arm length requirements of the child patient. This facilitates the medical staff to perform puncture surgery and improves the adaptability of puncture surgery for patients with different arm lengths. At the same time, the folded structure is relatively simple and has a large exposed area, which makes it easy to clean the blood that has been contaminated after the operation.
[0054] According to some embodiments of this application, the fixing arch 121 is made of rubber.
[0055] Among them, rubber, due to its deformable properties, can adapt to the hand size of most patients, and its soft texture can also improve patient comfort.
[0056] Please continue to refer to Figure 1 and Figure 2 and further refer to Figure 6 , Figure 6 This is a three-dimensional structural schematic diagram of the radial artery puncture and fixation device 100 provided in an embodiment of this application. According to some embodiments of this application, such as... Figure 1 , 2 and Figure 3 As shown, the first support member 110 is a long plate-shaped structure. The end of the first support member 110 away from the second support member 120 is provided with an abutment portion 111. The projected area of the abutment portion 111 on the plane perpendicular to the first support member 110 is greater than the projected area of the first support member 110.
[0057] In this embodiment, the purpose of providing the abutment portion 111 is to take into account that in some cases, it may be necessary to abut the abutment portion 111 under the patient's armpit to fix the radial artery puncture fixation device 100 provided in this embodiment to improve stability. Therefore, by providing the abutment portion 111 with a projected area on a plane perpendicular to the first support member 110 that is larger than the projected area of the first support member 110, the contact area of the abutment portion 111 with the patient's armpit can be effectively increased, providing higher stability.
[0058] Please continue to refer to Figure 1 , Figure 2 and Figure 6 and further refer to Figure 7 , Figure 7 This is a top view of the radial artery puncture fixation device 100 provided in an embodiment of this application. In this embodiment, the first support member 110 has a fixation groove 112. The depth of the fixation groove 112 is set from deep to shallow from the end where the first support member 110 is connected to the second support member 120 to the end of the first support member 110 away from the second support member 120. The fixation groove 112 is used for inserting the user's arm to restrict the movement of the user's arm.
[0059] By setting the fixing groove 112, the patient's arm can be better fixed on the first support 110, while also improving the patient's comfort.
[0060] It is understandable that, regarding the depth of the fixing groove 112, this embodiment of the application takes into account that when the patient inserts his arm into the fixing groove 112 from the end of the first support member 110 away from the second support member 120, the wrist, which is away from the patient's body, may have the greatest shaking amplitude. The patient's wrist corresponds to the end of the first support member 110 that is closer to the second support member 120. Therefore, the fixing groove 112 is the deepest at this point to ensure the best stabilizing effect.
[0061] Please refer to Figure 8 and Figure 9 , Figure 8 and Figure 9 This is a three-dimensional structural schematic diagram of the radial artery puncture and fixation device 100 provided in an embodiment of this application. According to some embodiments of this application, such as... Figure 5 and Figure 6 As shown, the first support member 110 includes a body part 113 and a telescopic part 114. The body part 113 and the telescopic part 114 are connected by a movable guide rail 115 so that the telescopic part 114 can switch between overlapping and extended states with the body part 113, thereby changing the length of the first support member 110.
[0062] Among them, the movable guide rail 115 refers to a connector that allows two components to slide relative to each other in a straight line.
[0063] By moving the relative positions of the main body 113 and the telescopic part 114, the area of the overlapping portion of the main body 113 and the telescopic part 114 can be increased or decreased, thereby changing the length of the first support member 110. When the patient's arm is short, the overlapping area between the main body 113 and the telescopic part 114 can be increased by moving the main body 113 and the telescopic part 114, thus shortening the length of the first support member 110 to accommodate the patient's arm length. Similarly, when the patient's arm is long, the length of the first support member 110 can be increased. In this way, it is possible to adapt to patients with different arm lengths, thereby improving the adaptability of the embodiments of this application.
[0064] Please refer to Figure 10 , Figure 10 This is a side view of the radial artery puncture fixation device 100 provided in an embodiment of this application. According to one embodiment of this application, a clamping structure 118 is provided at the end of the first support member 110 away from the second support member 120. The clamping structure 118 is clamped by bolts and is used to clamp the device to the edge of the bed to fix the radial artery puncture fixation device 100 to the edge of the bed.
[0065] By setting the clamping structure 118, the radial artery puncture fixation device 100 provided in this application embodiment can be fixed on the hospital bed, so that patients in a lying position can also conveniently perform radial artery puncture without having to sit up, which is beneficial for patients with limited mobility or paralysis to perform puncture surgery.
[0066] Please refer to Figure 11 , Figure 11 This is a three-dimensional structural diagram of the radial artery puncture and fixation device 100 provided in an embodiment of this application. Figure 11 As shown, according to one embodiment of this application, the first support member 110 has a double-layer structure.
[0067] Please refer to Figure 12 , Figure 12 This is a three-dimensional structural diagram of the radial artery puncture treatment bed 1000 provided in an embodiment of this application. According to another embodiment of this application, a radial artery puncture treatment bed 1000 is provided, including a treatment bed body 1100 and a radial artery puncture fixation device 100 from any of the above embodiments. One side of the treatment bed body 1100 has a connecting portion 1110 for connecting the radial artery puncture fixation device 100, so that the radial artery puncture fixation device 100 and the treatment bed body 1100 are fixedly connected to each other.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application 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 or all of the technical features therein.
