Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a finger protector with a pulse oximeter. Background Technology

[0002] Finger pulse oximeter clips are a commonly used medical device widely applied in clinical practice to monitor patients' blood oxygen saturation. However, existing finger pulse oximeter clips have some problems in actual use, especially when worn for extended periods or during continuous patient monitoring.

[0003] First, existing finger pulse oximeter clips can easily cause discomfort or even pain in patients' fingers when held for extended periods. Because the clips need to fit tightly against the patient's finger to ensure measurement accuracy, this tight grip often puts pressure on the finger, thus affecting patient comfort.

[0004] Secondly, some patients have sensitive or fragile skin, and prolonged use of finger pulse oximeter clips may lead to skin damage or pressure sores. This not only increases the patient's suffering but also places an additional burden on medical staff. Utility Model Content

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A finger protector with a pulse oximeter includes a protective cover body, which is worn on the user's finger. The protective cover body includes, from the outside to the inside, an isolation and pressure-resistant layer, a buffer layer, and a skin-friendly layer. A first detection window and a second detection window are respectively provided on the symmetrical sides of the protective cover body. The first detection window and the second detection window are connected to the inside of the protective cover body and are used to expose part of the user's finger.

[0007] The present invention is further configured such that: one end of the protective sleeve body is provided with an opening for a finger to pass through; when a finger passes through the protective sleeve body, the position of the first detection window or the second detection window corresponds to the nail area of ​​the finger.

[0008] The present invention is further configured such that: through holes are respectively provided on both sides of the protective sleeve body away from the opening, and both through holes penetrate the peripheral sidewall of the protective sleeve body to form the first detection window and the second detection window respectively, and the shape of the through holes matches the shape of the fingernail.

[0009] The present invention is further configured such that: a plurality of vent holes are provided on the peripheral sidewall of the protective cover body, and the vent holes are connected to the inner side of the protective cover body.

[0010] The present invention is further configured such that: the peripheral sidewall of the protective sleeve body is provided with anti-slip texture to increase friction.

[0011] The present invention is further configured such that the anti-slip texture includes several protrusions disposed on the peripheral sidewall of the protective cover body.

[0012] The present invention is further configured such that the protrusion is one or more of the following shapes: spherical, cylindrical, and prismatic.

[0013] The present invention is further configured such that: the isolation and pressure-resistant layer is made of silicone material, and / or the buffer layer is made of sponge material, and / or the skin-friendly layer is made of polyurethane material.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. By combining an isolation and pressure-resistant layer, a buffer layer, and a skin-friendly layer, the pressure of the finger pulse oximeter clip on the patient's fingers can be reduced, avoiding secondary injuries such as skin redness, blisters, and pressure sores caused by strong pressure, thus improving the protection of the user's fingers. At the same time, the presence of a detection window facilitates the monitoring of the user's blood oxygen saturation by the finger pulse oximeter clip.

[0016] 2. The shape of the detection window is set to match the shape of the fingernail, which has a guiding effect, making it easier for users to identify the wearing method and also making it easier for the fingernails to be exposed.

[0017] 3. By creating several ventilation holes on the protective case itself, the skin-friendly layer of the protective case does not completely contact the user's finger skin, allowing for natural ventilation, preventing sweaty fingers, and further improving the user's comfort when wearing it.

[0018] 4. By setting anti-slip textures on the outside of the protective case, the friction between the protective case and the finger pulse oxygen clip is increased, reducing the risk of the finger pulse oxygen clip slipping off and improving wearing stability.

[0019] 5. The isolation and pressure-resistant layer is made of silicone material, which is soft, breathable and elastic; the buffer layer is made of sponge material, which effectively relieves the direct pressure of the finger pulse oximeter clip on the patient's skin and reduces the feeling of pressure and discomfort; the skin-friendly layer is made of polyurethane material, which ensures that it fits the skin for a long time without irritation.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A finger protector with a pulse oximeter, such as Figures 1 to 3 As shown, it includes a protective sleeve body, which is generally designed as a finger sleeve with an internal cavity. It can be designed as a thumb or other finger shape as needed. The protective sleeve body is worn on the user's finger. One end of the protective sleeve body has an opening for the finger to pass through. After the finger passes through the protective sleeve body from the opening, the finger pulse clip is then worn on the finger covered by the protective sleeve body.

[0028] The protective case body comprises, from the outside to the inside, an insulating and pressure-resistant layer 1, a buffer layer 2, and a skin-friendly layer 3. The skin-friendly layer 3 is located on the inner side and contacts the user's fingers, while the insulating and pressure-resistant layer 1 is located on the outer side and contacts the finger pulse clip. The three layers are overlapped and fixed together with adhesive. The insulating and pressure-resistant layer 1 is made of silicone material, and / or the buffer layer 2 is made of sponge material, and / or the skin-friendly layer 3 is made of polyurethane material.

[0029] In this embodiment, the isolation and pressure-resistant layer 1 is made of medical-grade silicone material, which has the advantages of being soft, breathable, and highly elastic. The buffer layer 2 is made of highly elastic sponge to increase the force-bearing area of ​​the patient's fingers, reduce the squeezing force on the patient's fingers when held by the finger pulse oxygen clip, and ensure that while providing sufficient support, it will not cause pressure or discomfort to the patient's skin. This effectively relieves the direct pressure of the finger pulse oxygen clip on the patient's skin, reduces pressure and discomfort, lowers the risk of skin damage, protects the patient's skin health, and improves the patient's overall comfort. The skin-friendly layer 3 is made of existing polyurethane (PU) material, ensuring that it adheres to the skin for a long time without irritation. Because the protective sleeve itself is elastic, it can be adapted to users with different finger sizes and is not easy to fall off when worn on the fingers.

[0030] The protective sleeve body has a first detection window and a second detection window on its symmetrical sides. The first detection window and the second detection window are connected to the cavity inside the protective sleeve body. The first detection window and the second detection window are used to expose part of the user's finger. The infrared light emitted from the finger oxygen clip from above can pass through the finger and be received by the photodetector below, so that the user can accurately monitor blood oxygen saturation when wearing the finger clip.

[0031] In this embodiment, through holes 6 are respectively provided on both symmetrical sides of the protective sleeve body away from the opening. Both through holes 6 penetrate the peripheral sidewall of the protective sleeve body to form the first detection window and the second detection window. The shape of the through holes corresponds to the shape of a fingernail, and when a finger is inserted into the protective sleeve body, the position of the first or second detection window corresponds to the fingernail area. The shape of the through holes has a guiding effect, making it easier for users to identify how the protective sleeve body is worn, and exposing the fingernail also makes it easier to perform conventional finger pulse oximetry.

[0032] In this embodiment, the protective sleeve body has several ventilation holes 4 on its peripheral sidewall. These ventilation holes 4 penetrate the isolation and pressure-resistant layer 1, the buffer layer 2, and the skin-friendly layer 3, and connect to the inner side of the protective sleeve body. The ventilation holes 4 are distributed around the perimeter of the protective sleeve body and arranged in multiple rows along its length. By providing these ventilation holes 4, the skin-friendly layer 3 does not completely contact the patient's finger skin, allowing for natural ventilation, preventing sweating of the fingers, and further improving the dryness of the area where the skin-friendly layer 3 contacts the fingers.

[0033] In this embodiment, the protective sleeve body has anti-slip textures on its peripheral sidewalls to increase friction. These anti-slip textures increase the friction between the protective sleeve body and the finger pulse oxygen clip, making it less likely for the finger pulse oxygen clip to slip off the finger. This provides a certain degree of anti-slip and fixation, ensuring stability during testing.

[0034] The anti-slip texture includes several protrusions 5 disposed on the peripheral sidewall of the protective case body. The protrusions 5 are distributed around the periphery of the protective case body and arranged in multiple rows along the length of the protective case body. The protrusions 5 are spaced apart from the ventilation holes 4. The protrusions 5 can be one or more of the following shapes: spherical, cylindrical, and prismatic. In this embodiment, the protrusions 5 are spherical (hemispherical or partially spherical) protrusions fixed on the peripheral sidewall of the protective case body.

[0035] The working process of this utility model is as follows:

[0036] When a user needs to test their blood oxygen saturation, they first put the protective sleeve on their finger with the fingernail positioned at the detection window. Then, they put the finger pulse oxygen clip on the finger. The light emitted by the finger pulse oxygen clip's light source passes through the detection window, through the finger, and reaches the photodetector, accurately monitoring the user's blood oxygen saturation. This reduces the pressure and discomfort on the user's fingers from wearing the finger pulse oxygen clip for extended periods, effectively protecting the user's fingers.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
