Description
Technical Field
[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to a PICC catheter arm support. Background Art
[0002] PICC catheterization refers to the insertion of a central venous catheter through peripheral vein puncture, which is mainly used to provide medium- and long-term intravenous treatment for cancer patients. During this catheterization, the patient's arm needs to be supported and fixed by an arm fixation bracket.
[0003] When supporting the patient's arm, the existing arm bracket will fix the patient's arm by means of a wristband or the like in order to reduce the possibility of the patient's arm moving around due to the foreign body sensation. However, the fixation of the wristband will tighten around the patient's wrist, reducing the blood flow in the arm, making it impossible for blood to fill the blood vessels, causing the blood vessels to shrink, increasing the difficulty of puncture, and further increasing the difficulty of the entire PICC. For this reason, the present application provides a PICC catheterization arm bracket to improve this problem. Utility Model Content

DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0028] like Figure 1 and Figure 3 As shown, a PICC catheter arm support proposed in one embodiment of the present application includes:
[0029] A main frame 1, on which a mounting plate 2 for supporting the patient's arm is mounted, and the main frame 1 is used to support other parts of the device. When in use, the main frame 1 supports the mounting plate 2, and the mounting plate 2 supports the patient's arm;
[0030] The splints 3 are symmetrically slidably mounted on the mounting plate 2, and the splints 3 are used to clamp the patient's arm. A resistance spring 4 is installed between the splints 3, and the resistance spring 4 forces the splints 3 to move away from each other. There are two splints 3. When in use, the patient's arm is clamped by sliding the splints 3. At this time, the upper part of the patient's arm is not blocked by the splints 3. When the patient's arm is fixed, the impact on the blood in the patient's arm is reduced, and the medical staff's line of sight is reduced when the medical staff performs puncture;
[0031] The grip 5 mounted on the mounting plate 2 is used to be held by the patient. When in use, the patient's palm is fixed by asking the patient to hold the grip 5. When the patient holds the grip 5, the patient's sense of security is increased, and the possibility of the patient's arm moving randomly is reduced.
[0032] A limiting member 6 is installed between the mounting plate 2 and the grip 5. The limiting member 6 is used to limit the sliding of the splint 3 on the mounting plate 2. When in use, after the patient's arm is clamped by the sliding splint 3, the sliding of the splint 3 is limited by the limiting member 6. At this time, the resistance spring 4 is compressed, further reducing the mobility of the splint 3. The cooperation between the limiting member 6 and the resistance spring 4 increases the stability of the splint 3 when clamping.
[0033] Compared with the prior art, when the patient's arm is fixed by the splint 3 during use, the stability of the splint 3 is increased by the cooperation of the limiting member 6 and the resistance spring 4. While fixing the patient's arm, the impact on the blood flowability in the patient's arm is reduced, thereby reducing the impact on the PICC puncture operation.
[0034] like Figure 3 As shown, in some embodiments, the handle 5 is hinged on the mounting plate 2, so that the handle 5 can be stored by rotating it, thereby reducing the space occupied by the handle 5 when not in use. The limiting member 6 includes:
[0035] An inclined block 601 mounted on the clamping plate 3, with an inclined surface formed on the inclined block 601, the inclined block 601 is fixed to the clamping plate 3, and the inclined surface of the inclined block 601 is formed in a direction away from the handle 5;
[0036] A push block 602 is slidably mounted on the mounting plate 2. The push block 602 is also provided with an inclined surface. The inclined surface on the push block 602 is parallel to the inclined surface on the inclined block 601. The inclined surface on the push block 602 is opened toward the direction close to the handle 5. When the push block 602 slides toward the direction close to the handle 5, the push block 602 is guided by the inclined surface to contact the inclined block 601, thereby making the two clamping plates 3 close to each other.
[0037] A connecting rope 603 is used to connect the handle 5 and the push block 602. The connecting rope 603 is used to pull the push block 602 to slide on the mounting plate 2. The connecting rope 603 is connected to one end of the handle 5 close to the inclined block 601. When in use, the patient's arm is placed on the mounting plate 2, and the handle 5 is rotated so that the patient can grab the handle 5. When rotating, the side of the handle 5 close to the inclined block 601 moves away from the inclined block 601, thereby pulling the push block 602 on the mounting plate 2 to slide close to the handle 5, and then pressing the inclined block 601. While rotating the handle 5, the splints 3 are brought close to each other to clamp the patient's arm. When in use, it is more convenient, reduces the time required to fix the patient's arm, and increases the practicality of the device.
[0038] like Figure 4 As shown, in some embodiments, a limiting groove 8 is provided on the mounting plate 2, and a limiting rod 7 for being inserted into the limiting groove 8 is slidably installed on the handle 5. When the limiting rod 7 is located in the limiting groove 8, the rotation of the handle 5 is restricted. When the handle 5 is rotated to be held by the patient, the limiting rod 7 is inserted into the limiting groove 8 by sliding the limiting rod 7, thereby restricting the rotation of the handle 5. This increases the stability of the handle 5 when in use, so that the patient only needs to hold the handle 5 with his hand, without having to spend extra effort to ensure that the handle 5 is in a rotated state, thereby increasing the practicability of the device.
[0039] like Figure 4As shown, in some embodiments, a raising plate 9 is installed on the handle 5, and a connecting spring 10 is installed between the raising plate 9 and the limiting rod 7. The connecting spring 10 forces the limiting rod 7 to move away from the raising plate 9, and the raising plate 9 provides an installation position for the limiting rod 7. When in use, the limiting rod 7 contacts the mounting plate 2. When the handle 5 rotates, it drives the limiting rod 7 to slide on the mounting plate 2. At this time, during the rotation process, the position between the handle 5 and the mounting plate 2 changes, so that the position between the connection between the limiting rod 7 and the raising plate 9 and the mounting plate 2 changes, and the connecting spring 10 is compressed. When the handle 5 is rotated into place, the connecting spring 10 pushes the limiting rod 7 to be inserted into the limiting groove 8. When the handle 5 is rotated into place, the limiting rod 7 is inserted into the limiting groove 8 through the cooperation of the connecting spring 10, thereby completing the restriction of the rotation of the handle 5, further reducing the operation time and improving the practicality of the device.
[0040] like Figure 1 and Figure 3 As shown, in some embodiments, a sliding groove 11 is opened on the mounting plate 2, and the sliding groove 11 passes through the mounting plate 2. A connecting plate 12 that slides with the sliding groove 11 is installed on the splint 3. The connecting plate 12 is located at the bottom of the mounting plate 2, and the inclined block 601 is installed on the splint 3 through the connecting plate 12. When in use, the connecting plate 12 makes the entire limiting member 6 located at the bottom of the mounting plate 2 and will not contact the patient's arm located above the mounting plate 2, thereby reducing the impact on the patient's arm during use. The sliding groove 11 limits the sliding path of the connecting plate 12 when in use, thereby increasing the stability of the splint 3 when sliding.
[0041] like Figure 2 As shown, in some embodiments, an extension plate 13 is installed on the handle 5, the extension plate 13 is perpendicular to the handle 5, the connecting rope 603 is connected to the handle 5 through the extension plate 13, the extension plate 13 is installed on the side of the handle 5 close to the inclined block 601, and is vertically connected to the handle 5. After the handle 5 is rotated into place, the extension plate 13 extends the maximum distance between the handle 5 and the inclined block 601, so that the maximum sliding distance of the push block 602 on the mounting plate 2 is increased, so that it can better resist the inclined block 601, thereby improving the feasibility of the device.
[0042] like Figure 2 As shown, in some embodiments, a connecting rod 14 is installed on the extension plate 13 and the push block 602, and a rotating sleeve 15 is rotatably installed on the connecting rod 14. The connecting rope 603 connects the extension plate 13 and the push block 602 through the rotating sleeve 15. Since the movement path of the handle 5 on the mounting plate 2 is rotation, and the movement path of the push block 602 is linear motion, the connection point between the connecting rope 603 and the two is prone to bending during movement. Through the rotation coordination of the rotating sleeve 15, the connection point between the connecting rope 603 and the two can be moved, thereby reducing the wear of the connecting rope 603 during movement and increasing the service life of the connecting rope 603.
[0043] like Figure 1 As shown, in some embodiments, a flexible pad 16 is installed between the splints 3. When the splint 3 clamps the patient's arm, the flexible pad 16 contacts the patient's arm. The flexible pad 16 is made of sponge. When in use, the flexible pad 16 flexibly contacts the patient's arm, thereby reducing the possibility of wear on the patient's arm during fixation and improving the practicability of the device.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
