Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a universal blood oxygen clamp. Background Art

[0002] The blood oxygen clip is a commonly used blood oxygen monitoring instrument that can accurately measure the blood oxygen content and is of great help to the patient's blood oxygen management. The working principle of the blood oxygen clip is to stick the finger or other skin surface, and then measure the changes in the oxygen concentration in the blood by emitting and receiving light beams, thereby indirectly measuring blood oxygen.

[0003] The blood oxygen clamp is generally composed of an upper clamp, a lower clamp and a torsion spring rotating shaft connecting the upper clamp and the lower clamp. The blood oxygen probe is usually installed on the upper clamp, and the blood oxygen measurement is performed by clamping the fingertips.

[0004] However, the existing blood oxygen clip has a narrow scope of application. For some special groups of people, such as users with long nail polish or infants, the blood oxygen probe cannot be aligned with the fingernail, and the changes in blood oxygen saturation cannot be accurately sensed, resulting in low blood oxygen saturation readings or no display.

[0005] In addition, since the clamping force of the blood oxygen clamp is applied through the torsion spring rotating shaft at the edge of the blood oxygen clamp, the clamping force is indirectly transmitted, making it difficult to set the clamping force of the finger clamping position in the middle of the blood oxygen clamp to an appropriate force. If the clamping force of the torsion spring rotating shaft is too large, it will be unbearable for the user, and if it is too small, light leakage will occur, affecting the measurement accuracy; and the clamping force applied by the torsion spring rotating shaft at the edge will cause the clamping force on both sides of the finger to be inconsistent, that is, the force on the side close to the torsion spring rotating shaft is large, and the force on the other side is small, affecting the user's comfort. Utility Model Content

[0006] The technical problem to be solved by the embodiments of the present utility model is to provide a universal blood oxygen clamp to improve the scope of application.

[0007] In order to solve the above technical problems, an embodiment of the utility model proposes a universal blood oxygen clamp, including an upper clamp, a lower clamp and a torsion spring rotating axis connecting the upper clamp and the lower clamp. An upper clamp groove running through the left and right is provided at the bottom of the upper clamp, and a lower clamp groove running through the left and right is correspondingly provided on the lower clamp.

[0008] Furthermore, an anti-slip portion is provided in the lower clamping groove.

[0009] Furthermore, light shielding portions are provided on the edges of the upper clamping groove and the lower clamping groove.

[0010] Furthermore, the lower clamp is composed of a decompression platform and a lower clamp seat, the lower clamp groove is arranged on the decompression platform, the torsion spring rotating shaft is connected to the lower clamp seat, guide holes are arranged at the front and rear of the decompression platform, the lower clamp seat is provided with guide columns corresponding to the guide holes, and a spring is sleeved on the guide columns.

[0011] Furthermore, a limiting portion is convexly provided on the top of the guide column, and a limiting groove corresponding to the limiting portion is provided on the decompression platform.

[0012] Furthermore, anti-slip grooves are provided on the upper surface of the upper clamp and the lower bottom surface of the lower clamp seat.

[0013] The beneficial effects of the utility model are as follows: the utility model adopts horizontally placed upper clamping grooves and lower clamping grooves, so that the fingers can be directly clamped horizontally during measurement, and can be suitable for different groups of people; the utility model adopts a pressure relief platform structure, and the clamping force is provided by directly pushing up the springs on both sides of the lower clamping groove, which solves the problem that the clamping force is difficult to set and the force on both sides of the finger is uneven.

DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model is further described in detail below in conjunction with the drawings and specific embodiments.

[0022] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0024] Please refer to Figure 1 to Figure 5 The universal blood oxygen clamp of the embodiment of the utility model includes an upper clamp, a lower clamp and a torsion spring rotating shaft connecting the upper clamp and the lower clamp (a common rotating shaft with a torsion spring). The upper clamp is provided with a blood oxygen probe for detecting the blood oxygen concentration at the user's fingernail. The blood oxygen probe is externally connected to a blood oxygen tester or directly connected to a micro blood oxygen test unit integrated on the upper clamp (a common structure). The upper clamp, the lower clamp, the torsion spring rotating shaft, and the blood oxygen probe are existing common structures.

[0025] An upper clamp groove with left and right openings is provided at the bottom of the upper clamp, and a lower clamp groove with left and right openings is provided on the lower clamp. When in use, the user's fingers are clamped between the upper clamp groove and the lower clamp groove. The utility model provides a transverse upper clamp groove and a lower clamp groove, which facilitates the transverse clamping of the user's fingers, and can be clamped and measured normally even if the user has long nails on his fingertips. The edges of the upper clamp groove and the lower clamp groove are both provided with a shading portion to prevent light leakage, which causes signal interference to the blood oxygen probe and makes the measurement inaccurate. Preferably, the shading portion adopts a silicone ring.

[0026] As an implementation mode, an anti-slip portion is provided in the lower clamping groove, which increases the friction between the lower clamping groove and the fingertips of the user's fingertips to prevent relative sliding between the user's fingertips and the blood oxygen probe during measurement, thereby affecting the measurement.

[0027] As an implementation method, the lower clamp is composed of a pressure relief platform and a lower clamp seat, the lower clamp groove is arranged on the pressure relief platform, the torsion spring rotating shaft is connected to the lower clamp seat, the pressure relief platform is provided with guide holes at the front and rear, the lower clamp seat is provided with guide posts corresponding to the guide holes, and the guide posts are sleeved with springs. In specific implementation, the guide posts are arranged on the lower clamp seat by bolts, which is convenient for assembly and production. When the upper and lower clamps are reset, the top of the guide posts abuts against the bottom of the upper clamp, so that the force of the torsion spring rotating shaft acting on the upper and lower clamps cannot act on the user's fingertips, and then the torsion spring rotating shaft will not apply uneven clamping force to the user's fingertips. The utility model adopts a pressure relief platform structure, so that when clamping the user's fingertips, the clamping force on the user's fingertips is realized by the springs on both sides, and the force on both sides of the user's fingertips is uniform, which improves the user's comfort; and the clamping force is directly applied by the spring, so that the clamping force is more controllable, so that it is convenient for manufacturers to accurately control the clamping force of the universal blood oxygen clamp shipped from the factory within the range that the user feels comfortable and does not affect the measurement.

[0028] As an implementation method, a limiting portion is convexly provided on the top of the guide column, and the limiting portion prevents the pressure relief platform and the lower clamp seat from separating. A limiting groove corresponding to the limiting portion is provided on the pressure relief platform, and the limiting groove makes the top of the guide column flush with the pressure relief platform, which is more beautiful, and when the upper clamp and the lower clamp are reset, there is no gap between the upper clamp and the lower clamp (pressure relief platform).

[0029] As an implementation method, the upper surface of the upper clamp and the lower bottom surface of the lower clamp seat are both provided with anti-slip grooves, and the anti-slip grooves make it easier for users to pinch the upper clamp and the lower clamp open.

[0030] The working principle of the utility model is as follows: when measurement is required, pinch open the upper clamp and the lower clamp, and put the fingertip between the upper clamp groove and the lower clamp groove; loosen the upper clamp and the lower clamp, and under the action of the rotating shaft of the torsion spring, the upper clamp and the lower clamp rotate towards each other, and the pressure relief platform is compressed by the fingertip; when the top of the guide column abuts against the bottom of the upper clamp, the pressure relief platform is compressed to the bottom by the fingertip, so that the fingertip is clamped in the upper clamp groove and the lower clamp groove, and measurement begins; after the measurement is completed, pinch open the upper clamp and the lower clamp, move the finger away, loosen the upper clamp and the lower clamp, and the rotating shaft of the torsion spring resets the upper clamp and the lower clamp.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
