Description

Protective sleeve for oxyhemoglobin saturation monitoring line

Technical Field

The utility model relates to the field of blood oxygen monitoring, in particular to a protective sleeve of a blood oxygen saturation monitoring line.

Background

The oxygen saturation (SaO2) is the percentage of the volume of oxygenated hemoglobin bound by oxygen (HbO2) in the blood to the volume of total bindable hemoglobin (Hb), i.e. the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. Thus, monitoring arterial oxygen saturation (SaO2) allows for an estimate of oxygenation and hemoglobin oxygen carrying capacity of the lungs. Real-time monitoring of arterial blood oxygen concentration is important in clinical care, since many clinical conditions cause a lack of oxygen supply, which directly affects normal cellular metabolism and is also seriously life-threatening.

The finger stall type photoelectric sensor is mainly used clinically, during measurement, the sensor is only required to be sleeved on a finger of a person, the finger is used as a transparent container for containing hemoglobin, red light with the wavelength of 660nm and near infrared light with the wavelength of 940nm are used as incident light sources, the light transmission intensity passing through a tissue bed is measured, the concentration of the hemoglobin and the blood oxygen saturation are calculated, and the instrument can measure the blood oxygen saturation of the human body.

At present, the oxyhemoglobin saturation is continuously monitored clinically, and the oxyhemoglobin saturation monitoring fingerstall is worn at the fingertip of a patient all the time, and because the fingertip moves more, and the fingertip is frequently changed to wear, moreover, the oxyhemoglobin saturation monitoring line and the particularity of the structure of the connection part of the fingerstall lead to the easy loss and even breakage of the part, influence clinical use, lead to inaccurate, cost-increased monitoring and the like. Therefore, a protective sleeve of the oxyhemoglobin saturation monitoring line is needed to be designed, and the loss of the connecting part of the oxyhemoglobin saturation monitoring line and the finger sleeve is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a protective sleeve for a blood oxygen saturation monitoring wire aiming at the defects of the prior art, and particularly relates to a liquid silica gel coated protective sleeve for prolonging the service life of the blood oxygen saturation monitoring wire.

The purpose of the utility model is realized by the following technical scheme: a protective sleeve for a blood oxygen saturation monitoring line comprises a sleeve body, an accommodating cavity, an opening, a nipple-shaped bulge and a groove;

the inner layer of the sleeve body is a plastic shell, and the outer layer of the sleeve body is a liquid silica gel coating layer; the plastic shell on the inner layer of the sleeve body is formed by connecting two hollow cylinders with the same outer diameter and different inner diameters; two hollow cylinders inside the sleeve body form an accommodating cavity, and the shape of the accommodating cavity is matched with the connection position of the blood oxygen saturation monitoring line finger sleeve.

Furthermore, the side surface of the sleeve body is provided with an opening, one side of the sleeve body is provided with a plurality of nipple-shaped bulges at the opening, the other side of the sleeve body is provided with a groove corresponding to the nipple-shaped bulges, and the groove and the nipple-shaped bulges are matched with each other to seal the opening.

Furthermore, the plastic shell is made of PC or PA, and the thickness of the plastic shell is 0.5-1mm or 1.5-2 mm.

Further, the thickness of the liquid silica gel coating layer is 2-3 mm.

Furthermore, the outer surface of the liquid silica gel coating layer is printed with a pattern layer.

Furthermore, a flannelette layer is arranged on the inner surface of the plastic shell.

The utility model has the beneficial effects that: the double-layer integrated structure is reasonably utilized, the plastic shell and the liquid silica gel coating layer are integrally injection-molded, and the inner plastic shell has high hardness, so that the repeated bending of the oxyhemoglobin saturation monitoring wire can be effectively prevented, and the abrasion is reduced; the liquid silica gel on the outer layer has small hardness and small pressure on the skin, and can protect the skin of a patient. Overall speaking, this utility model can effectively reduce clinical instrument use cost, avoids because of the monitoring line wearing and tearing the monitoring that leads to inaccurate, makes things convenient for nurse clinical work, increases patient's comfort level, improves patient's satisfaction.
