Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a ruler for measuring the length of jugular vein distension. Background Technology

[0002] Currently, existing methods for measuring jugular vein distension first involve adjusting the patient's position to a semi-recumbent position at an angle of 30°-45°. Then, the distance from the upper edge of the clavicle to the highest point of jugular vein distension is measured using a ruler. This measurement is compared with the distance from the upper edge of the clavicle to the angle of the mandible to determine whether jugular vein distension has occurred. However, for some patients, especially those with limited mobility, this method is clearly very difficult and time-consuming.

[0003] Utility model CN213696909U discloses a device for measuring the length of jugular vein distension, comprising: a base rod, a level, an angle disc, and a measuring ruler; a mounting portion is provided at the first end of the base rod; the level is mounted on the base rod to ensure the base rod is in a horizontal position; the angle disc is fixed to the mounting portion, and the angle disc has 1-4 angle regions to indicate that the measuring ruler can rotate into the angle region, and the angle between the edge line of the angle region and the center line of the base rod is 30°-45°; the measuring ruler is rotatably mounted on the mounting portion. The device for measuring the length of jugular vein distension provided by this utility model can quickly measure the length of jugular vein distension, and it is easy to operate and very convenient for measurement.

[0004] However, the above-mentioned prior art still has shortcomings in use: 1. Although the above-mentioned prior art discloses that the measuring ruler has a storage cavity, a measuring ruler can be installed in the storage cavity, and then adjusted according to different measuring distances, there is a problem that it is inconvenient to switch between measuring rulers of different lengths; 2. Moreover, the exposed measuring ruler does not have a protective function and is prone to bending and damage.

[0005] Therefore, this utility model provides a ruler for measuring the length of jugular vein distension. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a jugular vein distension length measuring ruler to solve the problems mentioned in the background technology. This utility model has the advantages of more convenient operation for switching between different length measurements, and also has the advantage of protecting the measuring plate when not in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a jugular vein distension length measuring ruler, comprising a device body, a base rod, an angle disc located at one end of the base rod, and a measuring plate rotatably connected to one end of the base rod. A handle is provided at the other end of the base rod. The measuring plate includes a ruler plate one and a ruler plate two, which have different lengths. A damper is provided between the ruler plate one and the ruler plate two at the rotatable connection point between the ruler plate one and the ruler plate two and the base rod. A limit plate is provided on one side of the base rod, and the ruler plate one and the ruler plate two are in an overlapping state when rotated into the limit plate.

[0008] Furthermore, a T-shaped pin is provided at one end of the base rod, and the damper includes a rubber sleeve and a support spring. The rubber sleeve is sleeved on the T-shaped pin and located between the first ruler plate and the second ruler plate. The two ends of the rubber sleeve are fixedly connected to the resistance-increasing pads, and the support spring is sleeved on the rubber sleeve with its two ends abutting against the adjacent resistance-increasing pads respectively.

[0009] Furthermore, a square-section connecting block is fixedly installed in the middle of the T-shaped pin, and the connecting block is located inside the rubber sleeve.

[0010] Furthermore, one end of the T-shaped pin is fixedly connected to a screw, and one end of the base rod is fixedly connected to a connecting plate that is screwed into the screw.

[0011] Furthermore, the limiting plate has a groove-shaped structure and magnets are glued to both sides inside it, and magnetic blocks are glued to the opposite sides of the ruler plate one and ruler plate two.

[0012] Furthermore, one end of the handle is provided with a slide rail that engages with the damping sliding mechanism of the base rod, and one end of the handle is fixedly connected to a protective sleeve that is gapped around the outside of the base rod.

[0013] Furthermore, a sliding sleeve is fixedly connected to the inside of the slide near the opening, and a friction-increasing rubber sleeve that is interference-fitted with the base rod is fixedly fitted inside the sliding sleeve.

[0015] 1. In this utility model, a measuring plate is provided consisting of a ruler plate one and a ruler plate two, wherein the ruler plate one and the ruler plate two have different lengths, and a damper is installed between them. Under the action of the damper, the ruler plate one and the ruler plate two can rotate independently and stop at a fixed point. When in use, the ruler plate one and the ruler plate two can be rotated to the measuring angle position as needed for measurement. This setting has the advantage of making the operation of switching between different length measurements more convenient.

[0016] 2. In this utility model, the handle and the base rod are configured to slide together axially. By fixing a protective sleeve to one end of the handle facing the measuring plate, the measuring plate can be partially hidden inside the protective sleeve after the handle slides. This not only reduces the overall space occupied, but also effectively protects the measuring plate. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a jugular vein distension length measuring ruler, including a device body 1, a base rod 11, an angle disk 12 located at one end of the base rod 11, and a measuring plate 13 rotatably connected to one end of the base rod 11. A handle 14 is provided at the other end of the base rod 11, and a level is provided on the rod body of the base rod 11. The angle disk 12 and the measuring plate 13 are used in a measuring cooperation manner as described in the patent documents mentioned in the background art.

[0023] In this technical solution, the measuring plate 13 includes a first ruler 131 and a second ruler 132, which have different lengths. Depending on the measurement length, either the first ruler 131 or the second ruler 132 can be rotated to the measurement position. A damper 2 is provided between the first ruler 131 and the second ruler 132. The damper 2 is located at the rotational connection between the first ruler 131 and the second ruler 132 and the base rod 11. The function of the damper 2 is to increase the resistance to the rotation of the first ruler 131 and the second ruler 132, so that they can remain stable after rotation, and their rotation will not affect each other.

[0024] Specifically, one end of the base rod 11 is provided with a T-shaped pin 111. In a preferred implementation, one end of the T-shaped pin 111 is fixedly connected to a screw 1111, and one end of the base rod 11 is fixedly connected to a connecting plate 112 that is screwed to the screw 1111 on one side. That is to say, the T-shaped pin 111 is detachable. One end of the ruler plate 131 and the ruler plate 2 132 are both provided with insertion holes that can be inserted into the T-shaped pin 111. The damper 2 includes a rubber sleeve 21 and a support spring 22. The rubber sleeve 21 is fitted onto the T-shaped pin 111 and located between ruler plate one 131 and ruler plate two 132. Both ends of the rubber sleeve 21 are fixedly connected to resistance-increasing pads 211, which are made of rubber. The support spring 22 is fitted onto the rubber sleeve 21, with its two ends abutting against adjacent resistance-increasing pads 211. Under the action of the support spring 22, ruler plate one 131 and ruler plate two 132 are pressed against the adjacent resistance-increasing pads 211, thereby increasing the frictional resistance of the contact. In use, the other side of the connecting plate 112 is fixedly connected to the angle plate 12.

[0025] Among them, a square-section connecting block 1112 is fixedly installed in the middle of the T-shaped pin 111. The connecting block 1112 is located inside the rubber sleeve 21. The connecting block 1112 is set so that the rubber sleeve 21 will not twist.

[0026] In this embodiment, a limiting plate 3 is provided on one side of the base rod 11. When the ruler plate 131 and the ruler plate 2 132 rotate into the limiting plate 3, they are in an overlapping state. The limiting plate 3 serves to limit the ruler plate 131 and the ruler plate 2 132. When not in use, rotating the ruler plate 131 and the ruler plate 2 132 makes them approximately overlap with the base rod 11, reducing the space occupied.

[0027] Furthermore, the limiting plate 3 has a groove-shaped structure and magnets 31 are glued to both sides inside it. Magnetic blocks 5 are glued to the opposite sides of the ruler plate 131 and the ruler plate 2 132. This arrangement allows the ruler plate 131 and the ruler plate 2 132 to stay stably after being stored, and there will be no problem of free rotation.

[0028] In this embodiment, one end of the handle 14 is provided with a slide rail 141 that is damped and slides in a sliding fit with the base rod 11. Preferably, a sliding sleeve 1411 is fixedly connected to the slide rail 141 near the opening and is sleeved on the outside of the base rod 11. A resistance-increasing rubber sleeve 6 that is interference-fitted with the base rod 11 is fixedly sleeved inside the sliding sleeve 1411. The resistance-increasing rubber sleeve 6 can increase the sliding resistance between the handle 14 and the base rod 11. One end of the handle 14 is fixedly connected with a protective sleeve 142 that is gapped and sleeved on the outside of the base rod 11. When the handle 14 slides to the limit position in the direction of the angle plate 12, the protective sleeve 142 will be sleeved on the outside of one end of the ruler plate 131 and the ruler plate 132, thereby effectively protecting the ruler plate 131 and the ruler plate 132.

[0029] Working principle: When ruler plate 2 132 is needed, manually push ruler plate 2 132 outward so that it is away from the limiting plate 3. Then, with the help of angle disc 12, rotate it to the measuring position. Then, hold handle 14 to take the measurement. After the measurement is completed, manually push ruler plate 2 132 and let it enter the limiting plate 3. Then slide handle 14 so that the protective sleeve 142 is put on the outside of ruler plate 1 131 and ruler plate 2 132. Then it can be stored.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
