Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a peripheral venous pressure monitoring device. Background Technology

[0002] Peripheral venous pressure refers to the venous blood pressure measured in the peripheral large veins at the level of the right atrium. It is used to assess right ventricular function, venous return, and venous reflux.

[0003] Currently, the most primitive clinical method involves having the patient lie flat and slowly dripping normal saline through an indwelling peripheral venous catheter. When the dripping normal saline gradually reaches equilibrium with the venous pressure, the height of the water in the external tube is measured with a tape measure, which is the peripheral venous pressure. This operation requires two people to work together and is time-consuming and laborious.

[0004] Patent CN 215272727U discloses a disposable peripheral venous manometry device. This device requires puncture, but because the puncture needle is connected to a plastic tube, the difficulty of puncture is greatly increased, and the patient has to endure the pain of repeated punctures. In addition, injecting saline solution into the top of the plastic tube also increases the possibility of contamination. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a peripheral venous pressure monitoring device.

[0011] In some embodiments, the top of the hose is provided with a cap, and the top of the cap is provided with a ring buckle.

[0012] In some specific embodiments, the cover is a plug-in cover.

[0013] In some specific embodiments, the lid is a folding lid.

[0014] In some specific embodiments, a filter screen is also provided between the cap and the top opening of the hose.

[0015] In some specific embodiments, the telescopic bend is composed of several folds or wavy undulations in the sidewall of the hose.

[0016] In some specific embodiments, the peripheral venous pressure monitoring device is further provided with a bracket and a hook disposed on the bracket.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a peripheral venous pressure monitoring device that is easy for medical personnel to operate, making it both portable and convenient to use. No puncture is required when using this device, reducing patient discomfort. The pre-sealed saline solution also reduces the possibility of contamination during operation. It effectively prevents blockage at the bends of the tubing, ensuring more reliable and easily obtainable data. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0028] Example 1:

[0029] like Figure 1-2 As shown, a peripheral venous pressure monitoring device includes a tubing 1 and an infusion nipple 2 located at the bottom of the tubing 1 for connecting an indwelling needle. The tubing 1 contains a closed saline reservoir 3. The tubing 1 has a scale 4 on the lower side wall of the saline reservoir 3, and the tubing 1 has a telescopic bend below the scale 4.

[0030] This technical solution employs a pre-filled design, pre-sealing the saline solution within the tubing 1 to effectively prevent contamination. Since the 0 mark needs to be aligned with the right atrium at the start of measurement, tubing 1 requires manual bending. To prevent blockage at the bend, a telescopic bend is designed to improve the flexibility of tubing 1. An infusion nipple 2 is fitted to the end of tubing 1 for direct connection to an indwelling needle, avoiding the risks of puncture or even multiple punctures. In practical use, after peripheral venous pressure monitoring is completed, the infusion nipple 2 can be retained, and the tubing can be replaced with an infusion strip for infusion.

[0031] The bottom of the saline storage section 3 is equipped with a switch 5 that connects or closes both sides of the lumen of the tubing 1, similar to a two-way valve. When the switch 5 is open, the saline solution pre-packaged in the tubing 1 can flow out smoothly. The switch 5 can be a rotary knob switch, such as a glass stopcock switch used in burettes, or a plug-in switch. The top of the tubing 1 is equipped with a cap 6, and the top of the cap 6 is equipped with a ring buckle 11. The cap 6 is a plug-in cap or a flip-top cap. A filter screen 7 is also provided between the cap 6 and the top opening of the tubing 1 to reduce contamination of the saline solution in the tubing 1 when the cap 6 is opened. The telescopic bend section 10 is composed of several folds or undulations on the side wall of the tubing 1, similar to the free bending section on a corrugated pipe or straw. The folded or undulating structure can be further unfolded. Therefore, when the tubing 1 is bent, a certain length is reserved in the telescopic bend section 10, so the tubing 1 will not cause blockage after bending. The peripheral venous pressure monitoring device is also equipped with a bracket 8 and a hook 9 on the bracket 8. The ring buckle 11 on the cover 6 is suspended from the hook 9 on the bracket 8, which facilitates the operation of medical staff.

[0032] When medical staff use it, connect the infusion nipple 2 to the indwelling needle, and bend the telescopic bend 10 so that the 0 mark on the tubing 1 is aligned with the right atrium. Open the switch 5 and the cap 6 to allow the saline solution to flow down. Then, after the water column stabilizes, read the pressure value.

[0033] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
