Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a device for detecting venous pressure. Background Technique

[0002] Venous pressure detection, especially the measurement of central venous pressure (CVP), is one of the important indicators for clinical hemodynamic observation. One measurement method is the manual measurement method, which requires the patient to lie flat. Normal saline is dripped through an indwelling central venous catheter. When the dripped normal saline gradually reaches equilibrium with the venous pressure, a tape measure is used to measure the height of the water in the outer pipeline to determine the CVP.

[0003] The following problems exist in the prior art:

[0004] When the existing manual measurement method is used to detect venous pressure, a simple self-made measurement device is adopted to measure the liquid level height in the pipeline. However, this method requires two people to operate together and is difficult to operate manually alone. Content of the Utility Model

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

The lower end of the measuring tube is fixedly connected to a base. A push ring is fixedly connected to the outer wall of the extension tube near the bottom end through a round rod. The outer side of the measuring tube is movably sleeved inside the push ring. Two symmetrically distributed limiting mechanisms are rotatably connected to the inner side wall of the push ring.

A button is fixedly connected to the middle part of the side of the rotating plate away from the extension tube. A plurality of vertically distributed inserting holes are symmetrically distributed in two columns on the left and right sides of the measuring tube. The outer sides of the inserting rods are movably sleeved inside the inserting holes.

[0009] Preferably, a limiting block is fixedly connected to the lower surface of the inner side wall of the push ring, and the limiting block is located on the side of the rotating plate close to the extension tube.

[0010] Preferably, friction lines are provided on the side of the button away from the rotating plate.

[0011] Preferably, the fixing mechanism includes a pressing block. Four rectangularly distributed limiting rods are movably sleeved at positions near the four corners on the left and right sides of the pressing block.

Specific implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0023] As Figure 1 , Figure 2 shown, a venous pressure detection device includes a measuring tube 1, an extension tube 2 is movably sleeved inside the measuring tube 1, a base 3 is fixedly connected to the lower end of the measuring tube 1, a push ring 4 is fixedly connected to the position near the bottom end of the outer wall of the extension tube 2 through a round rod, the inner side of the push ring 4 is movably sleeved on the outside of the measuring tube 1, two symmetrically distributed limiting mechanisms 5 are rotatably connected to the inner side of the side wall of the push ring 4, and a fixing mechanism 6 is fixedly connected to the position near the front side on the upper side of the base 3.

[0024] It should be noted that notches are provided on the rear sides of both the measuring tube 1 and the extension tube 2, and the pipeline can enter the inside of the measuring tube 1 and the extension tube 2 from the notches. The base 3 is composed of two sector-shaped pieces, and there is a certain gap in the middle for the pipeline to pass through.

[0025] As Figure 2 - Figure 4 shown, the limiting mechanism 5 includes a rotating plate 51, the middle parts of the front and rear sides of the rotating plate 51 are rotatably connected to the middle parts of the front and rear sides of the inner side of the side wall of the push ring 4, two symmetrically distributed first springs 52 are fixedly connected to the positions near the front and rear sides on the side of the rotating plate 51 away from the extension tube 2, two symmetrically distributed inserting rods 53 are slidably connected to the positions near the upper side on the side of the rotating plate 51 close to the extension tube 2 through rotating seats, a button 56 is fixedly connected to the middle part of the side of the rotating plate 51 away from the extension tube 2, a plurality of vertically distributed inserting holes 54 are provided in two columns symmetrically distributed in the left and right directions on the measuring tube 1, and the outer sides of the inserting rods 53 are movably sleeved inside the inserting holes 54.

[0026] It should be noted that when the inserting rod 53 is movably sleeved inside the inserting hole 54, the push ring 4 is fixed, so that the extension tube 2 is fixed relative to the measuring tube 1. Press the button 56 to cause the rotating plate 51 to rotate, so that the rotating plate 51 pulls the inserting rod 53 out of the inserting hole 54, so that the extension tube 2 can move up and down quickly relative to the measuring tube 1. Release the rotating plate 51 to cause the first spring 52 to push the rotating plate 51 to reset.

[0027] As Figure 3As shown, a limiting block 55 is fixedly connected to the inner lower surface of the side wall of the pushing ring 4, and the limiting block 55 is located on the side of the rotating plate 51 close to the extension pipe 2.

[0028] It should be noted that the limiting block 55 is used to limit the rotation amplitude of the rotating plate 51, so that the limiting mechanism 5 cannot fall off from the inner side wall of the pushing ring 4.

[0029] As Figure 4 shown, the side of the button 56 away from the rotating plate 51 is provided with friction lines.

[0030] It should be noted that the friction lines are used to increase the friction force between the hand and the button 56, so that when the pushing ring 4 is pushed upward, there will be no relative sliding between the hand and the pushing ring 4.

[0031] As Figure 2 、 Figure 5 shown, the fixing mechanism 6 includes a pressing block 61. Four limiting rods 62 distributed in a rectangle are movably sleeved on the positions near the four corners on the left and right sides of the pressing block 61. The lower sides of the limiting rods 62 are fixedly connected to the upper side of the base 3 near the front side. Second springs 63 are movably sleeved on the outer sides of the four limiting rods 62, and the second springs 63 are located above the pressing block 61.

[0032] It should be noted that the lower side of the base 3 is placed on the bed surface. The second spring 63 pushes the pressing block 61 downward. When the pipeline passes through the lower side of the pressing block 61, the pressing block 61 will tightly press the pipeline, so that the lower side of the pipeline is fixed.

[0033] As Figure 5 shown, a rubber pad 64 is embedded in the middle of the lower surface of the lower convex platform of the pressing block 61.

[0034] It should be noted that the rubber pad 64 is used to further increase the friction force between the pressing block 61 and the pipeline to prevent relative sliding between the pushing ring 4 and the pressing block 61.

[0035] Working principle of the utility model: First, the lower side of the base 3 is placed on the bed surface. The second spring 63 pushes the pressing block 61 downward. When the pipeline passes through the lower side of the pressing block 61, the pressing block 61 will tightly press the pipeline, so that the lower side of the pipeline is fixed. The rubber pad 64 is used to further increase the friction between the pressing block 61 and the pipeline to prevent relative sliding between the pushing ring 4 and the pressing block 61. By placing the pipeline inside the measuring tube 1 and the extension tube 2, then fixing the lower side of the pipeline with the pressing block 61, pushing the pushing ring 4, and finally measuring the liquid inside the pipeline with the scales on the measuring tube 1 and the extension tube 2, the purpose of rapid detection is achieved. When in use, only hold the device with one hand and the pipeline with the other hand, and it can be quickly operated alone by one person. Finally, when the insertion rod 53 is movably sleeved inside the insertion hole 54, the pushing ring 4 is fixed, so that the extension tube 2 is fixed relative to the measuring tube 1. Press the button 56, causing the rotating plate 51 to rotate, so that the rotating plate 51 pulls the insertion rod 53 out of the insertion hole 54, only allowing the extension tube 2 to move up and down quickly relative to the measuring tube 1. Release the rotating plate 51, causing the first spring 52 to push the rotating plate 51 back to its original position. The limiting block 55 is used to limit the rotation amplitude of the rotating plate 51, so that the limiting mechanism 5 cannot fall off from the inner wall of the pushing ring 4. By pressing the button 56, the extension tube 2 can slide up and down quickly. Release the button 56, causing the extension tube 2 to be fixed relative to the measuring tube 1, so that the extension tube 2 can be quickly adjusted, and at the same time, the problem that the extension tube 2 needs to be manually controlled and fixed after adjusting the extension tube 2 is avoided, which is convenient for the user to operate.
