Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a jugular vein puncture pillow. Background Technology

[0002] External jugular vein puncture is a commonly used clinical procedure, especially in pediatrics, emergency medicine, and intensive care. During external jugular vein puncture, the patient's head needs to be held at a specific angle to fully expose the puncture site; therefore, neck support is usually required to maintain this angle.

[0003] Currently, pillows are commonly used to stabilize a patient's neck and help maintain the head at a specific angle. While this method effectively holds the head at a specific angle, during puncture, the patient's position often needs to be changed depending on their condition to ensure a smooth procedure. After the position is changed, the pillow needs to be adjusted to re-stabilize the neck. Maintaining the patient's posture while adjusting the pillow significantly increases the difficulty for medical staff. Furthermore, conventional pillows are difficult to adjust quickly to the required angle, thus affecting the puncture outcome.

[0004] Therefore, the existing method of using a pillow to fix the patient's neck has the problem that the pillow needs to be adjusted while maintaining the patient's position, and the pillow is difficult to adjust to the required angle quickly, which increases the difficulty of the operation and affects the puncture effect. Utility Model Content

[0005] The purpose of this invention is to provide a jugular vein puncture pillow to solve the technical problem in the prior art where the pillow is difficult to adjust to the required angle when the patient needs to be kept in a fixed position, thus increasing the difficulty of the operation and affecting the puncture effect.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A jugular vein puncture pillow includes a base, on which a headrest is disposed for supporting the patient's neck;

[0008] The headrest is rotatably mounted on the base. An arc-shaped plate is provided at the connection between the base and the headrest. Multiple ratchet teeth are provided on the outer arc surface of the arc plate. A check rod is provided on the lower side of the headrest, and the check rod abuts against the arc plate.

[0009] The anti-return rod can move along the ratchet of the arc-shaped plate when the headrest is raised and abut against the upper side of the ratchet to prevent the headrest from falling, or move outward from the ratchet when the headrest needs to fall to unlock the headrest, thereby realizing the rapid adjustment of the headrest angle.

[0010] As a preferred embodiment of this utility model, the ratchet teeth are evenly distributed downwards on the outer arc surface of the arc-shaped plate.

[0011] As a preferred embodiment of this utility model, the ratchet is a three-stage ratchet, and when the anti-return rod abuts against each stage of the ratchet, the included angles between the headrest and the base are 30°, 45° and 60° respectively.

[0012] In a preferred embodiment of this utility model, a torsion spring is provided between the anti-return rod and the headrest, and the torsion spring can press the anti-return rod against the ratchet.

[0013] As a preferred embodiment of this utility model, the anti-return rod is provided with a handle connected to the outside. By prying open the handle, the anti-return rod can be pried away from the ratchet, thereby unlocking the headrest.

[0014] As a preferred embodiment of this utility model, the supporting end section of the headrest is arc-shaped.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention rotatably mounts a headrest on a base, and provides an arc-shaped plate and a stop rod on the base and headrest respectively. The stop rod can prevent the headrest from falling after the headrest is rotated upward to adjust the angle, or it can move the stop rod outward when the headrest needs to be lowered to adjust the angle, so that the headrest can rotate downward, thereby achieving rapid adjustment of the headrest angle during puncture.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown, this utility model provides a jugular vein puncture pillow, including a base 1, on which a headrest 2 is provided, which is used to support the patient's neck;

[0026] The headrest 2 is rotatably mounted on the base 1. An arc plate 11 is provided at the connection between the base 1 and the headrest 2. Multiple ratchet teeth 111 are provided on the outer arc surface of the arc plate 11. A check rod 21 is provided on the lower side of the headrest 2. The check rod 21 abuts against the arc plate 11.

[0027] The anti-return rod 21 can move along the ratchet 111 of the arc plate 11 when the headrest 2 is raised, and abut against the upper side of the ratchet 111 to prevent the headrest 2 from falling, or move outward from the ratchet 111 when the headrest 2 needs to fall, so as to unlock the headrest 2, thereby realizing the rapid adjustment of the angle of the headrest 2.

[0028] In this embodiment, the headrest 2 is rotatably mounted on the base 1, and an arc-shaped plate 11 is provided at the connection between the base 1 and the headrest 2. A stop rod 21 is provided on the headrest 2, and the stop rod 21 abuts against the arc-shaped plate 11. When the headrest 2 is rotated upward to adjust the angle, the stop rod 21 can be tightly locked onto the arc-shaped plate 11 to prevent the headrest 2 from falling, or it can be moved outward when the headrest 2 needs to be lowered to adjust the angle, so that the headrest 2 can be rotated downward to adjust.

[0029] Compared to existing methods that directly fix the patient's neck with a pillow, this embodiment uses an arc-shaped plate 11 and a stop rod 21 on the base 1 and the headrest 2, respectively. When the headrest 2 is raised and rotated to adjust the angle, the stop rod 21 is tightly locked onto the arc-shaped plate 11 to prevent the headrest 2 from falling. When the headrest 2 needs to be lowered to adjust the angle, the stop rod 21 can be moved outward to unlock it, so that the headrest 2 can be rotated downward to adjust, thereby quickly adjusting the headrest 2 to the required angle.

[0030] In order to enable the check rod 21 to be locked on the upper side of the ratchet 111 after adjustment, the following preferred embodiment is proposed.

[0031] like Figure 1 As shown, the ratchet teeth 111 are evenly distributed downwards on the outer arc surface of the arc plate 11.

[0032] Specifically, ratchet teeth 111 are distributed downwards on the outer arc surface of the arc plate 11. The upper side of each ratchet tooth 111 is perpendicular to the outer arc surface of the arc plate 11. The check rod 2 can move upwards along the oblique side of the ratchet tooth 111. When moving downwards, the lower end of the check rod 2 will be locked by the upper side of the ratchet tooth 111.

[0033] When fixing a patient's neck, the patient's neck is often fixed at 30°, 45° and 60° depending on the patient's condition. Therefore, the following preferred embodiments are proposed.

[0034] like Figure 1 As shown, ratchet 111 is a three-stage ratchet. When the check rod 211 abuts against each stage of ratchet 112, the included angles between the headrest 2 and the base 1 are 30°, 45° and 60° respectively.

[0035] Specifically, when the headrest 2 is adjusted to the three-level angle, the headrest 2 can be at 30°, 45° and 60° with the base 1 respectively.

[0036] In order to enable the anti-return rod 2 to move closely against the surface of the ratchet 111 when the headrest 2 is adjusted upwards, so as to lock onto the upper side of the ratchet 111 after adjustment, the following preferred embodiment is proposed.

[0037] like Figure 1 and 2 As shown, a torsion spring 211 is provided between the check rod 21 and the headrest 2, and the torsion spring 211 can press the check rod 21 against the ratchet 111.

[0038] Specifically, when the headrest 2 is raised to adjust the angle, the stop rod 211 can move closely against the ratchet 111 under the action of the torsion spring 211, and after the headrest 2 is adjusted, it is locked on the ratchet 111 to fix the headrest 2.

[0039] To enable the locking lever 21 to be unlocked and the headrest 2 to be lowered for adjustment, the following preferred embodiments are proposed.

[0040] like Figure 1 As shown, a handle 212 is connected to the outside of the anti-return rod 21. By prying open the handle 212, the anti-return rod 21 can be pried away from the ratchet 111, thereby unlocking the headrest 2.

[0041] Specifically, pulling the handle 212 outward can disengage the anti-return rod 21 from the ratchet 111, thereby allowing the headrest 2 to drop and adjust its angle. After releasing the handle 212, the anti-return rod 211 can be tightly pressed against the ratchet 111 under the action of the torsion spring 211.

[0042] When fixing a patient's neck, the patient's neck is often fixed at 30°, 45° and 60° depending on the patient's condition. Therefore, the following preferred embodiments are proposed.

[0043] In order for the headrest 2 to conform to the curve of the neck when supporting the patient's neck, the following preferred embodiments are proposed.

[0044] like Figure 1 As shown, the cross-section of the support end of the headrest 2 is arc-shaped.

[0045] Specifically, the support end of the headrest 2 is arc-shaped. When the headrest 2 is adjusted to 30°, 45° and 60° respectively, the support end of the headrest 2 can keep the arc facing the patient's neck, thereby providing comfortable support for the patient's neck.

[0046] In this embodiment, when in use, the headrest 2 is raised and adjusted to the required angle according to the patient's position. At this time, the check rod 21 can move along the outside of the ratchet 111 and lock on the upper side of the ratchet 111 after the adjustment is completed. Alternatively, the handle 212 can be pulled outward to lower the headrest 2 to the required angle. The handle 212 can be released and the headrest 2 can be locked at the current angle by the check rod 21.

[0047] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
