Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment, and in particular to a portable pulse oximeter that can be reliably installed. Background Technology

[0002] A pulse oximeter is a medical device that measures blood oxygen saturation or arterial hemoglobin saturation in a non-invasive manner. In order to make it more convenient to measure blood oxygen saturation or arterial hemoglobin saturation, portable pulse oximeters have gradually appeared on the market.

[0003] Existing portable pulse oximeters are usually connected to the human body via straps. However, the small contact area between the oximeter and the straps can lead to a lack of security, causing the end of the oximeter furthest from the straps to curl up. Furthermore, the existing straps are made of soft rubber, which is not breathable. Without ventilation gaps, this can easily cause skin allergies. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A portable pulse oximeter that can be reliably installed includes: a rubber sleeve, wherein a mounting groove is provided inside the rubber sleeve, and a main unit is disposed inside the rubber sleeve through the mounting groove; The surface of the rubber sleeve is provided with a U-shaped groove, and at least two limiting grooves are symmetrically opened on the inner surface of the rubber sleeve. The position and size of the U-shaped groove match the U-shaped boss. The surface of the host is fixedly provided with a U-shaped protrusion, and the bottom of the host is fixedly provided with at least two limiting protrusions.

[0005] As an improvement to the above technical solution, the bottom of both sides of the rubber sleeve is symmetrically provided with connecting grooves, and the bottom of the rubber sleeve is provided with a strap structure through the connecting grooves.

[0006] As an improvement to the above technical solution, the strap structure is composed of a strap boss, a strap body, a hook and loop fastener, and a loop and loop fleece. The strap boss is connected to the strap body at both ends. The hook and loop fastener is fixedly disposed on one end surface of the strap body, and the loop and loop fleece is fixedly disposed on the end surface of the strap body away from the hook and loop fastener.

[0007] As an improvement to the above technical solution, the strap protrusion is fitted to the bottom of the rubber sleeve, and the connection between the two ends of the strap protrusion and the strap body is curved and has an arc.

[0008] As an improvement to the above technical solution, the size and position of the U-shaped slot are matched with the U-shaped boss, and the size and position of the limiting groove are matched with the limiting protrusion.

[0009] The beneficial effects of this utility model are: The fully enclosed, detachable design of the sleeve and main unit prevents the main unit from lifting up during use and facilitates easy maintenance. The U-shaped slot and protrusion design ensure a snug fit after installation, while the limiting groove and protrusion design provide a more secure installation. The strap is made of multi-layered fleece material, allowing for breathability. The skin-friendly layer directly contacts the skin, reducing the risk of allergies. The strap can be easily replaced when dirty. The strap features heat-pressed Velcro hooks and fleece for secure fastening. Attached Figure Description

[0012] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0013] Existing portable pulse oximeters are usually connected to the human body via straps. However, the small contact area between the oximeter and the straps can lead to a lack of security, causing the end of the oximeter furthest from the straps to curl up. Furthermore, the existing straps are made of soft rubber, which is not breathable. Without ventilation gaps, this can easily cause skin allergies.

[0014] To resolve this issue, please refer to [link / reference]. Figure 1-3 A portable pulse oximeter that can be reliably installed includes: a rubber sleeve 1, wherein a mounting groove 101 is provided inside the rubber sleeve 1, and a main unit 2 is disposed inside the rubber sleeve 1 through the mounting groove 101; The surface of the rubber sleeve 1 is provided with a U-shaped groove 102, and at least two limiting grooves 103 are symmetrically opened on the inner surface of the rubber sleeve 1. The position and size of the U-shaped groove 102 are matched with the U-shaped boss 201. The surface of the host 2 is fixedly provided with a U-shaped protrusion 201, and the bottom of the host 2 is fixedly provided with at least two limiting protrusions 202.

[0015] In use, the main unit 2 is inserted into the sleeve 1 through the mounting slot 101 for installation. After the main unit 2 is inserted into the sleeve 1, the U-shaped protrusion 201 will be located in the U-shaped slot 102, and the limiting protrusion 202 at the bottom of the main unit 2 will be inserted into the limiting groove 103 on the inner surface of the sleeve 1. Through the fully enclosed detachable design between the sleeve 1 and the main unit 2, it can prevent one end of the main unit 2 from lifting up during use, and it is also convenient to maintain the main unit 2 at any time. The design of the U-shaped slot 102 and the U-shaped protrusion 201 can make the sleeve 1 and the main unit 2 fit more closely after installation, and the design of the limiting groove 103 and the limiting protrusion 202 makes the installation of the sleeve 1 and the main unit 2 more stable.

[0016] In one embodiment, see Figure 2 The bottom of the rubber sleeve 1 is symmetrically provided with connecting grooves 104 on both sides, and the bottom of the rubber sleeve 1 is provided with a strap structure 3 through the connecting grooves 104.

[0017] During installation, the two ends of the strap structure 3 are inserted into the connecting grooves 104 to install it on the bottom of the rubber sleeve 1. Since the size of the strap protrusion 301 matches the bottom of the rubber sleeve 1 but is longer than the connecting groove 104, when the strap body 302 is inserted into the connecting groove 104, the strap protrusion 301 will be fixed between the two connecting grooves 104. In addition, the detachable design of the strap structure 3 makes it easy to replace it in time when it gets dirty.

[0018] In one embodiment, see Figure 2 The strap structure 3 is composed of a strap protrusion 301, a strap body 302, a hook and loop fastener 303, and a loop and loop fastener fleece 304. The strap protrusion 301 is connected to the strap body 302 at both ends. The hook and loop fastener 303 is fixedly disposed on one end surface of the strap body 302. The loop and loop fastener fleece 304 is fixedly disposed on the end surface of the strap body 302 away from the hook and loop fastener 303.

[0019] When using, the strap protrusion 301 is placed against the skin of the wrist and the strap body 302 is wrapped around the wrist. Finally, the hook and loop fasteners 303 and velvet 304 are used to fix it. The strap body 302 is made of velvet and has a multi-layer structure. The multi-layer material of the strap body 302 is breathable and the skin-friendly layer is in direct contact with the skin, reducing skin allergies.

[0020] In one embodiment, see Figure 2 The strap protrusion 301 is attached to the bottom of the rubber sleeve 1, and the connection between the two ends of the strap protrusion 301 and the strap body 302 is curved and has an arc.

[0021] When in use, due to the curved design at the connection between the strap protrusion 301 and the strap body 302, there is a gap between the bottom of the connection between the strap protrusion 301 and the strap body 302 and the wrist when it is installed on the wrist, which improves wearing comfort.

[0022] In one embodiment, see Figure 1-2 The size and position of the U-shaped slot 102 are matched with the U-shaped boss 201, and the size and position of the limiting groove 103 are matched with the limiting protrusion 202.

[0023] During installation, the design of the U-shaped slot 102 and the U-shaped protrusion 201 allows the rubber sleeve 1 and the main unit 2 to fit more closely after installation, and the design of the limiting groove 103 and the limiting protrusion 202 makes the installation of the rubber sleeve 1 and the main unit 2 more stable.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
