Description

Technical Field

[0001] This application relates to the field of vital sign detection, and more particularly to a blood oxygen probe device. Background Technology

[0002] A pulse oximeter is a commonly used vital sign detection device used to detect whether the blood oxygen concentration of a person or animal is abnormal.

[0003] Chinese invention patent CN101797158B discloses a blood oxygen sensor, such as... Figure 1 As shown, the blood oxygen sensor includes a sensor and a strap.

[0004] Sensor 1 includes a body, a crossbeam 12, a light-emitting photoelectric element, and a light-receiving photoelectric element (not shown). The body 11 has a first clamping part 111, an arc-shaped base, and a second clamping part 113 that are integrally connected in sequence, and the first clamping part 111, the base 112, and the second clamping part 113 form a U-shape.

[0005] The inner surface of the first clamping part 111, the inner surface of the base 112, and the inner surface of the second clamping part 113 are connected in sequence to form the inner surface of the body 11. The inner surface 118 encloses a measurement space with an opening 114, and the measurement part (such as the foot of a newborn) can enter the measurement space 115 through the opening 114.

[0006] The outer surface of the first clamping part 111, the outer surface of the base 112, and the outer surface of the second clamping part 113 are sequentially connected to form the outer surface of the body 11, and the outer surface 119 of the body 11 is recessed with a slot 14.

[0007] A crossbeam 12 protrudes from the outer surface of the base 112 and spans the slot 14, forming a mating hole 15 between the crossbeam and the slot 14 for the strap 2 to pass through.

[0008] The strap 2 is strip-shaped and includes two back-to-back Velcro layers 21 and 22, each with a Velcro hook layer 23 and 24 fixed at both ends. The strap 2 is divided into an integrally connected mounting section and a wrapping section 26 along its length. The mounting section 25 includes an integrally connected first connecting section 251, a stop section 252, and a second connecting section 253. One hook layer 23 is located on the first connecting section 251, and the other hook layer 24 is located on the wrapping section 26. The second connecting section 253 is integrally connected to the wrapping section 26.

[0009] During assembly, the mounting section 25 of the strap 2 is fitted onto the crossbeam 12. The first connecting section 251 of the mounting section 25 passes through the mating hole 15, the stop section 252 rests against the crossbeam 12, and the second connecting section 253 is located above the crossbeam 12. The hook layer 23 on the first connecting section 251 is adhered to the rough layer 21 of the second connecting section 253, thus achieving a reliable connection between the strap 2 and the sensor 1. During measurement, the sensor 1 is placed on the measurement site, so that the first clamping part 111, the base 112, and the second clamping part 113 of the sensor body 11 clamp the measurement site in three directions. Then, the winding section 26 of the strap 2 is wrapped around the measurement site. Finally, the hook layer 24 of the winding section 26 facing the body 11 is adhered to the rough layer 22 of the winding section facing away from the body 11. The winding section 26 is secured in the slot 14 on the outer surface 119 of the body, thus reliably fixing the blood oxygen sensor to the measurement site. After the measurement is completed, the bonded fleece layer 21 and hook layer 23 can be peeled off, the strap 2 can be discarded, and the sensor 1 can be reused after cleaning.

[0010] In this embodiment, since the crossbeam 12 protrudes above the body 11, when the strap 2 is wrapped and fixed, the protruding crossbeam 12 is pressed under the strap 2, causing the body 11 to be subjected to excessive force at the location of the crossbeam 12, resulting in deformation and compression of the measured part, leading to discomfort during wear. Furthermore, due to the limitation of the width of the slot 14 and the mating hole 15, the strap 2 is relatively narrow, resulting in greater pressure on the measured part in contact with the strap 2, which also affects wearing comfort. This is especially true since the blood oxygen sensor is used to detect the blood oxygen concentration of newborns, whose skin is more delicate; a narrow strap 2 could even cause skin injuries. On the other hand, the strap 2 is relatively soft, making it difficult to pass the mounting section 25 of the strap 2 through the mating hole 15.

[0011] In another embodiment, such as Figure 2 As shown, the first clamping part 111 has a notch 117 extending through its inner and outer surfaces. The crossbeam 12 is disposed within the notch 117 and forms a mating hole between it and the first clamping part 111 for the strap 2 to pass through. During assembly, the mounting section 25 of the strap can pass through the mating hole 15 and be fitted onto the crossbeam 12.

[0012] In this embodiment, the crossbeam 12 is positioned at the end of the first clamping part 111, which avoids discomfort caused by the crossbeam 12 protruding. However, the space at the end of the first clamping part 111 is small, so the mating hole 15 is small, making it difficult for the strap 2 to pass through. If the strap 2 is narrowed to facilitate passing through the mating hole 15, the problem of the strap 2 pressing on the skin will be further aggravated.

[0013] In another embodiment, such as Figure 3As shown, the outer surface is a flat surface without any slots, and the crossbeam 12 protrudes from the outer surface 119 of the body. Although the specification states that this type of sensor is suitable for a wider strap, the width of which can be greater than the width of the body (i.e., the width of the outer surface 119), the structure of the wider strap is not disclosed.

[0014] Based on this, the technical problems existing in the pulse oximeter probe include:

[0015] 1. Due to the limitation of the width of the slot 14 and the mating hole 15, the width of the strap 2 is relatively narrow, resulting in greater pressure on the measured part in contact with the strap 2, which affects the comfort of wearing. In particular, since the blood oxygen sensor is used to detect the blood oxygen concentration of newborns, the skin of newborns is relatively fragile, and the narrow strap 2 may even injure the skin of newborns.

[0016] 2. The material of the strap 2 is relatively soft, making it difficult to pass the installation section 25 of the strap 2 through the mating hole 15.

[0017] 3. When the crossbeam 12 is set on the outside of the body 11, since the crossbeam 12 protrudes above the body 11, and the thicker strap 2 needs to pass through the mating hole 15 formed between the crossbeam 12 and the body 11, the crossbeam 12 protrudes too high. When the strap 2 is wrapped and fixed, the protruding crossbeam 12 is pressed under the strap 2, causing the body 11 to be subjected to excessive force at the position of the crossbeam 12, which causes deformation and compression of the tested part, affecting the wearing comfort.

[0018] 4. When the crossbeam 2 is set at the end of the body 11, the space at the end of the body 11 is small, so the mating hole 15 formed is smaller than when the crossbeam 2 is set on the outside of the body 11, and the strap 2 is less likely to pass through. Utility Model Content

[0019] In a first aspect, embodiments of this application provide a pulse oximeter device, which includes: a probe assembly and a strap assembly;

[0020] The probe assembly includes a body, an extension, and a detection element. The detection element is disposed on the inner surface of the body.

[0027] The extension is a single part connected to one end of the main body. After the extension and the main body are together enclosed, the perforated section of the extension is located on the outside of the main body, so that the side of the strap hole facing the receiving space is blocked by the main body and isolated from the receiving space.

[0028] In one optional embodiment of this application, the extension includes a first extension and a second extension. The first extension includes a perforated section, and the strap hole penetrates the inner and outer surfaces of the perforated section. After the extension and the body together enclose the extension, the perforated section of the first extension is located outside the second extension, so that the side of the strap hole facing the receiving space is blocked by the second extension and isolated from the receiving space.

[0029] In one optional embodiment of this application, the body portion includes a first body portion, a second body portion, and a third body portion connected in sequence, with one end of the first extension portion fixed to the end of the first body portion and one end of the second extension portion fixed to the end of the third body portion.

[0031] In one optional embodiment of this application, the body portion includes a first body portion, a second body portion, and a third body portion connected sequentially.

[0032] The strap hole is located at the end of the first body part and extends through the inner and outer surfaces of the first body part; the extension is connected to the end of the third body part.

[0033] After the extension and the main body are together enclosed, the strap hole is located on the outside of the extension, so that the side of the strap hole facing the receiving space is blocked by the extension and isolated from the receiving space.

[0034] In one optional embodiment of this application, the extension includes a first connecting segment and a perforated segment connected to the first connecting segment. The thickness of the perforated segment is greater than the thickness of the first connecting segment, and the strap hole penetrates the inner and outer surfaces of the perforated segment in the thickness direction.

[0035] In one optional embodiment of this application, the first belt and the third belt have the same structure;

[0036] Both sides of the first strip and / or the third strip are provided with hook layers.

[0037] Secondly, embodiments of this application provide a blood oxygen probe device, which includes: a probe assembly and a strap assembly;

[0038] The probe assembly includes a body, a connecting part, a protective part, and a detection element. The body has an inner surface and an outer surface. The inner surface of the body encloses an accommodating space with an opening. The detection element is disposed on the inner surface of the body.

[0039] The protective part is connected to the end of the body part, the connecting part is disposed on the protective part or the body part and forms a strap hole between the connecting part and the protective part or the body part for the strap assembly to pass through, and the connecting part and the strap hole are located on the outside of the protective part;

[0040] The strap assembly includes a first strap body, a second strap body, and a third strap body connected in sequence. The first strap body includes a first base layer and a first hook layer disposed on at least one side of the first base layer. The second strap body includes a second base layer and a fleece layer disposed on at least one side of the second base layer. The third strap body includes a third base layer and a third hook layer disposed on at least one side of the third base layer. The size of the first strap body is smaller than the size of the second strap body, and the strap hole allows the first strap body to pass through but not the second strap body.

[0041] When the strap assembly is attached to the probe assembly, the first strap passes through the strap hole and the first hook layer at the end of the first strap is detachably connected to the loop layer of the second strap. The side of the first strap facing the receiving space is blocked by the protective part and isolated from the receiving space. The second strap is wrapped around the outer surface of the body and the protective part. The third hook layer of the third strap is detachably connected to the loop layer of the second strap.

[0042] In one optional embodiment of this application, the widths of the first strip and the third strip are smaller than the width of the second strip; and / or

[0043] The thickness of the first and third strips is less than the thickness of the second strip; and / or

[0044] The hardness of the first belt and the third belt is greater than the hardness of the second belt.

[0045] In one optional embodiment of this application, the protective part includes a first protective part and a second protective part. The first protective part is fixed to one end of the main body, and the second protective part is fixed to the other end of the main body. The first protective part and the second protective part can deform to surround the main body.

[0046] When the first protective part and the second protective part deform and surround the main body, the ends of the first protective part and the second protective part abut or partially overlap.

[0047] The connecting portion is disposed on the outer surface of the first protective portion, and the strap hole is formed between the connecting portion and the outer surface of the first protective portion.

[0048] In one optional embodiment of this application, a groove is provided on the outer side of one end of the main body, and the connecting part is disposed on the main body and located in the groove;

[0049] The protective part and the connecting part are disposed at the same end of the main body, and the protective part is connected to the inner surface of one end of the main body, such that the connecting part and the strap hole are both located on the outside of the protective part.

[0050] Beneficial effects:

[0051] 1. When connecting the strap assembly to the probe assembly, the smaller first strap body can more easily pass through the strap hole, while the larger second strap body is restricted from passing through the strap hole. Furthermore, the smaller first strap body can be designed to be harder, making its hardness greater than that of the second strap body, thus facilitating its passage through the strap hole.

[0052] 2. The strap hole is located on the extension portion extending from the end of the main body or on the main body itself, and the strap hole penetrates the inner and outer surfaces of the extension portion or the inner and outer surfaces of the main body. A connecting structure, such as a connecting portion, can be formed at the strap hole location on the extension portion or the main body, enabling connection with the first or third strap body in the strap assembly. Compared to the case where the crossbeam is located on the outside of the main body and protrudes beyond it, this embodiment avoids excessive stress on the connecting structure protruding from the main body due to pressure from the strap assembly, thus improving the comfort of the tested area.

[0053] 3. At the same time, the size of the first band is smaller than that of the second band. Therefore, when connecting the band assembly to the probe assembly, the smaller first band is easier to pass through the band hole, while the larger second band makes contact with the tested area, making the tested area more comfortable and avoiding damage to the skin of the tested area by the second band.

[0054] 4. When the strap assembly is attached to the probe assembly, the extension and the main body together enclose the space, so that the side of the strap hole facing the receiving space is blocked and isolated from the receiving space. The first strap passes through the strap hole, and the hook layer at the end of the first strap is detachably connected to the nap of the second strap. The side of the first strap facing the receiving space is blocked and isolated from the receiving space. This blocks the smaller and harder first strap in the strap assembly from contacting the skin of the tested area, improving comfort and preventing skin damage.

[0055] 5. Furthermore, since the size of the first strap is smaller than that of the second strap, even if the strap hole is small, the first strap can pass through without being passed through by the larger second strap. Compared to the prior art where the crossbeam is located at the end of the body, and the hole formed between the crossbeam and the body is smaller due to the smaller space at the end, making it difficult for the strap to pass through, this application can effectively solve this problem by using a smaller first strap.

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the application or its application or use.

[0082] Example 1

[0083] like Figures 4a-7d This application provides a pulse oximeter device 100, which includes a probe assembly 10 and a strap assembly 20. The probe assembly 10 includes a body portion 11, an extension portion 13, and a detection element 19. The detection element 19 is disposed on the inner surface of the body portion 11. The extension portion 13 is connected to the end of the body portion 11 and can deform to form a receiving space 15 with the body portion 11 for accommodating the measured area. The probe assembly 10 also has a strap hole 16, which penetrates the inner and outer surfaces of the extension portion 13 in the thickness direction or penetrates the inner and outer surfaces of the body portion 11 in the thickness direction. Figures 4a-4c , Figures 6a-6b This application uses the example of the strap hole 16 penetrating the inner and outer surfaces of the extension 13 in the thickness direction as an example for illustrative purposes. Other optional embodiments, such as... Figures 5a-5b The strap hole 16 penetrates the inner and outer surfaces of the body portion 11 in the thickness direction. The following is an exemplary description of this embodiment.

[0084] like Figures 7a-7dThe strap assembly 20 includes a first strap body 21, a second strap body 22, and a third strap body 23 connected in sequence. The first strap body 21 includes a first base layer 211 and a first hook layer 212 disposed on at least one side of the first base layer 211. The second strap body 22 includes a second base layer 221 and a fleece layer 222 disposed on at least one side of the second base layer 221. The third strap body 23 includes a third base layer 231 and a third hook layer 232 disposed on at least one side of the third base layer 231. The size of the first strap body 21 is smaller than the size of the second strap body 22. The strap hole 16 allows the first strap body 21 to pass through but not the second strap body 22. When the strap assembly 20 is attached to the probe assembly 10, the first strap 21 passes through the strap hole 16, and the first hook layer 212 at the end of the first strap 21 is detachably connected to the pile layer 222 of the second strap 22. The side of the first strap 21 facing the receiving space 15 is blocked by the body portion 11 or the extension portion 13 and isolated from the receiving space 15. The second strap 22 is wrapped around the outer surface of the body portion 11 and the extension portion 13. The third hook layer 232 of the third strap 23 is detachably connected to the pile layer 222 of the second strap 22.

[0085] When connecting the strap assembly 20 to the probe assembly 10, firstly, the first strap 21 of the strap assembly 20 is passed through the strap hole 16 of the probe assembly 10. Then, the first strap 21 is bent backward so that the first hook layer 212 at the end of the first strap 21 is connected to the nap 222 of the second strap 22, thereby achieving a secure connection between the strap assembly 20 and the probe assembly 10. Because the first strap 21 is relatively narrow, it is easy to pass the first strap 21 through the strap hole 16. When fixing the probe assembly 10 to the part to be measured, the part to be measured is first placed in the receiving space 15 of the probe assembly 10, and then the strap assembly 20 is wrapped around the outer surface of the probe assembly 10. The side of the first strap 21 facing the receiving space 15 is blocked by the body part 11 or the extension part 13 and isolated from the receiving space 15. Finally, the third hook layer 232 of the third strap 23 of the strap assembly 20 is connected to the wool layer 222 of the second strap 22, thereby fixing the probe assembly 10 firmly to the part to be measured.

[0086] When connecting the strap assembly 20 to the probe assembly 10, the smaller first strap 21 can more easily pass through the strap hole 16, while restricting the larger second strap 22 from passing through the strap hole 16. Furthermore, the smaller first strap 21 can be designed to be harder, making its hardness greater than that of the second strap 22, facilitating its passage through the strap hole 16. Simultaneously, when connecting the strap assembly 20 to the probe assembly 10, the larger second strap 22 contacts the test site, providing greater comfort and preventing skin damage from the second strap 22. For example, as... Figures 7a-7dThe second band 22 is restricted, meaning it cannot pass through the strap hole 16. Therefore, the width of the second band 22 is not limited by the width of the strap hole 16, and the second band 22 can be wider. This results in a larger contact area between the second band 22 and the measured area when the pulse oximeter device 100 is fixed to the measured area, preventing damage to the measured area from the strap assembly 20. Furthermore, the second band 22 is made of a flexible material, which improves comfort when the pulse oximeter device 100 is fixed to the measured area.

[0087] The strap hole 16 is provided on the extension 13 extending from the end of the main body 11 or on the main body 11 itself, and the strap hole 16 penetrates the inner and outer surfaces of the extension 13 or the inner and outer surfaces of the main body 11. A connecting structure, such as a connecting portion 12, can be formed at the location of the strap hole 16 on the extension 13 or the main body 11, which can be connected to the first strap 21 or the third strap 23 in the strap assembly 20. Compared to the case where the crossbeam is located on the outside of the main body and protrudes beyond it, this embodiment avoids excessive stress on the location of the connecting structure on the main body 11 due to pressure from the strap assembly 20, thereby improving the comfort of the tested area.

[0088] When the strap assembly 20 is attached to the probe assembly 10, the extension 13 and the main body 11 together enclose the strap hole 16 so that the side facing the receiving space 15 is blocked and isolated from the receiving space 15. The first strap 21 passes through the strap hole 16, and the first hook layer 212 at the end of the first strap 21 is detachably connected to the nap 222 of the second strap 22. The side of the first strap 21 facing the receiving space 15 is blocked and isolated from the receiving space 15. This blocks the smaller and harder first strap 21 in the strap assembly 20 from contacting the skin of the tested area, improving comfort and preventing skin damage.

[0089] Furthermore, since the size of the first strap 21 is smaller than that of the second strap 22, even if the strap hole 16 is small, the first strap 21 can pass through without being passed through by the larger second strap 22. Compared to the situation where the crossbeam is located at the end of the body, and the hole formed between the crossbeam and the body is smaller due to the smaller space at the end, which is not conducive to the passage of the strap, this application can effectively solve this problem by using the smaller first strap 21.

[0090] An alternative embodiment, such as Figures 7a-7dIn one embodiment, the size of the first strap 21 is smaller than the size of the second strap 22, meaning the width of the first strap 21 is smaller than the width of the second strap 22. In another optional embodiment, the size of the first strap 21 is smaller than the size of the second strap 22, meaning the thickness of the first strap 21 is smaller than the thickness of the second strap 22. In yet another optional embodiment, the size of the first strap 21 is smaller than the size of the second strap 22, meaning the width of the first strap 21 is smaller than the width of the second strap 22, and the thickness of the first strap 21 is smaller than the thickness of the second strap 22. This facilitates the passage of the first strap 21 through the strap hole 16.

[0091] For example, the hardness of the first belt 21 is greater than that of the second belt 22, which facilitates the passage of the first belt 21 through the strap hole 16.

[0092] For example, the size of the third strap 23 is smaller than the size of the second strap 22. In one optional embodiment, the width of the third strap 23 is smaller than the width of the second strap 22. In another optional embodiment, the thickness of the third strap 23 is smaller than the thickness of the second strap 22. In yet another optional embodiment, both the width and thickness of the third strap 23 are smaller than the width and thickness of the second strap 22. This facilitates the passage of the third strap 23 through the strap hole 16. In practical applications, the third strap 23 can also pass through the strap hole 16; the user can choose to have either the first strap 21 or the third strap 23 pass through the strap hole 16 according to actual needs.

[0093] For example, the hardness of the third belt 23 is greater than that of the second belt 22, which facilitates the passage of the third belt 23 through the strap hole 16.

[0094] In one optional embodiment, both sides of the first strap 21 are provided with a first hook layer 212, and both sides of the third strap 23 are provided with a third hook layer 232. In other optional embodiments, both sides of the first strap 21 are provided with a first hook layer 212, and one side of the third strap 23 is provided with a third hook layer 232. In other optional embodiments, one side of the first strap 21 is provided with a first hook layer 212, and both sides of the third strap 23 are provided with a third hook layer 232. Exemplarily, the first hook layer 212 of the first strap 21 and the third hook layer 232 of the third strap 23 can both be hook and loop fasteners, and the loop layer 222 of the second strap 22 can be a hook and loop fastener.

[0095] For example, both surfaces of the second tape 22 may be provided with a loop layer 222, so that regardless of whether the first tape 21 passes through the strap hole 16 from the inside to the outside or from the outside to the inside, after the second tape 22 is wrapped around the probe assembly 10, the third hook layer 232 of the third tape 23 can be connected to a loop layer 222 of the second tape 22.

[0096] For example, for ease of use, the structures of the first strap 21 and the third strap 23 can be identical, so that the first strap 21 and the third strap 23 can be used without distinction, and both the first strap 21 and the third strap 23 can pass through the strap hole 16 of the probe assembly 10 and be connected to the probe assembly 10. In other alternative embodiments, the structures of the first strap 21 and the third strap 23 can also be different.

[0097] like Figures 4a-4c The extension 13 includes a first extension 13a and a second extension 13b. The first extension 13a includes a perforated section 133, through which a strap hole 16 penetrates the inner and outer surfaces of the perforated section 133. After the extension 13 and the main body 11 are together enclosed, the perforated section 133 of the first extension 13a is located outside the second extension 13b, so that the side of the strap hole 16 facing the receiving space 15 is blocked by the second extension 13b and isolated from the receiving space 15. The length of the first extension 13a may be greater than the length of the second extension 13b. It is understood that the length of the first extension 13a may also be equal to or less than the length of the second extension 13b. In this embodiment, after the extension portion 13 and the main body portion 11 are enclosed together, the strap hole 16 on the first extension portion 13a is defined outside the second extension portion 13b, so that the side of the strap hole 16 facing the receiving space 15 is completely blocked by the second extension portion 13b and isolated from the receiving space 15. After the first hook layer 212 at the end of the first strap 21 or the third hook layer 232 at the end of the third strap 23 passes through the strap hole 16, the portion of the first strap 21 or the third strap 23 at the strap hole 16 is blocked by the second extension portion 13b and isolated from the receiving space 15, so as to separate it from the tested area and avoid the first strap 21 or the third strap 23 from the skin of the tested area, so as to prevent discomfort or even damage to the tested area.

[0098] The body portion 11 includes a first body part 111, a second body part 112, and a third body part 113 connected in sequence. The various parts and connections of the body portion 11 in this embodiment are not limited to these. One end of the first extension 13a is fixed to the end of the first body part 111, and one end of the second extension 13b is fixed to the end of the third body part 113. The second extension 13b is pre-formed into an arc shape, and its free end is close to the end of the first body part 111. Therefore, during the process of fixing the probe assembly 10 to the measured part, it is no longer necessary to manually adjust the first extension 13a and the second extension 13b to ensure that the end of the first extension 13a is located outside the second extension 13b, making operation easier. Furthermore, after pre-forming the second extension 13b, it is bent towards the interior of the receiving space 15. When the measured part is placed within the receiving space 15, the second extension 13b also serves to fix and guide it, ensuring that the measured part is placed in the correct position.

[0099] like Figure 5a and 5b The strap hole 16 is located at the end of the first body part 111 and extends through the inner and outer surfaces of the first body part 111. The extension 13 is connected to the end of the third body part 113. After the extension 13 and the body part 11 are enclosed together, the strap hole 16 is located on the outside of the extension 13, so that the side of the strap hole 16 facing the receiving space 15 is blocked by the extension 13 and isolated from the receiving space 15. In this embodiment, after the extension portion 13 and the main body portion 11 are enclosed together, the strap hole 16 is defined on the outside of the extension portion 13, so that the side of the strap hole 16 facing the receiving space 15 is completely blocked by the extension portion 13 and isolated from the receiving space 15. After the first hook layer 212 at the end of the first strap 21 or the third hook layer 232 at the end of the third strap 23 passes through the strap hole 16, the portion of the first strap 21 or the third strap 23 at the strap hole 16 is blocked by the extension portion 13 and isolated from the receiving space 15, so as to separate it from the test area and avoid the first strap 21 or the third strap 23 from the skin of the test area, so as to prevent discomfort or even damage to the test area.

[0100] like Figure 6a and 6bThe extension 13 includes a perforated section 133, with a strap hole 16 penetrating the inner and outer surfaces of the perforated section 133. There is only one extension 13, which is connected to one end of the main body 11. After the extension 13 and the main body 11 are together enclosed, the perforated section 133 of the extension 13 is located on the outside of the main body 11, so that the side of the strap hole 16 facing the receiving space 15 is blocked by the main body 11 and isolated from the receiving space 15. Specifically, the extension 13 is connected to the end of the first main body 111, and the strap hole 16 is closer to the free end of the extension 13 than the end of the first main body 111. In this embodiment, after the extension portion 13 and the main body portion 11 are together enclosed, the strap hole 16 is defined on the outside of the main body portion 11, so that the side of the strap hole 16 facing the receiving space 15 is completely blocked by the main body portion 11 and isolated from the receiving space 15. After the first hook layer 212 at the end of the first strap 21 or the third hook layer 232 at the end of the third strap 23 passes through the strap hole 16, the portion of the first strap 21 or the third strap 23 at the strap hole 16 is blocked by the main body portion 11 and isolated from the receiving space 15, so as to separate it from the tested area and avoid the first strap 21 or the third strap 23 from the skin of the tested area, so as to prevent discomfort or even damage to the tested area.

[0101] like Figures 4a-4c , Figure 6a and Figure 6b The extension 13 includes a first connecting segment 131 and a perforated segment 133 connected in sequence. A strap hole 16 penetrates the inner and outer surfaces of the perforated segment 133, and the thickness of the perforated segment 133 is greater than the thickness of the first connecting segment 131. One end of the first connecting segment 131 is connected to the end of the first body portion 111, and the other end of the first connecting segment 131 is connected to one end of the perforated segment 133. For example, the connection between the perforated segment 133 and the first connecting segment 131 is smoothly transitioned, forming an arc-shaped step or an inclined step. During the process of the first strap 21 or the third strap 23 passing through the strap hole 16 and connecting to the second strap 22, the smooth transition of the first strap 21 or the third strap 23 facilitates a smooth appearance of the strap assembly 20 wrapped around the probe assembly 10.

[0102] For example, the extension 13 further includes a second connecting segment 132, which is connected to the other end of the perforated segment 133. The thickness of the perforated segment 133 is greater than the thickness of the second connecting segment 132. For example, the connection between the perforated segment 133 and the second connecting segment 132 is smoothly transitioned to form an arc-shaped step or an inclined step. During the process of the first strap 21 or the third strap 23 passing through the strap hole 16 and connecting with the second strap 22, the smooth transition of the first strap 21 or the third strap 23 facilitates a smooth appearance of the strap assembly 20 wrapped around the probe assembly 10.

[0103] For example, the first body portion 111 and the third body portion 113 are arranged opposite each other.

[0104] For example, the first body portion 111 has a first mounting position 1111 with an opening facing the receiving space 15, and the third body portion 113 has a second mounting position 1131 with an opening facing the receiving space 15. The positions of the first mounting position 1111 and the second mounting position 1131 correspond to each other. The detection element 19 includes a first detection element 191 and a second detection element 192. The first detection element 191 is disposed in the first mounting position 1111, and the second detection element 192 is disposed in the second mounting position 1131. One of the first detection element 191 and the second detection element 192 is a light-emitting element, and the other is a photosensitive element. The light emitted by the light-emitting element passes through the measured area and is received by the photosensitive element. The blood oxygen concentration of the measured area can be obtained based on the light received by the photosensitive element. In other embodiments, both the light-emitting element and the photosensitive element can be disposed in the first body portion 111 or the third body portion 113. The light emitted by the light-emitting element is reflected by the measured area and is received by the photosensitive element. The blood oxygen concentration of the measured area can be obtained based on the light received by the photosensitive element.

[0105] The first detection element 191 and the second detection element 192 are electrically connected to an external pulse oximeter via a wire 18. Specifically, one end of a wire 18 is electrically connected to the pulse oximeter, and the other end passes through the first mounting position 1111 and is then electrically connected to the first detection element 191. The second body portion 112 has a channel 1121 connecting the first mounting position 1111 and the second mounting position 1131. One end of another wire 18 is electrically connected to the pulse oximeter, and the other end passes sequentially through the first mounting position 1111, the channel 1121, and the second mounting position 1131 to be electrically connected to the second detection element 192. In other optional embodiments, the other wire 18 may not pass through the channel 1121; for example, the other wire 18 may directly pass through the second mounting position 1131 to be electrically connected to the second detection element 192. Exemplarily, a sleeve is also provided between the pulse oximeter and the first body portion 111, through which one or two wires 18 located between the pulse oximeter and the first body portion 111 pass.

[0106] For example, the first body portion 111, the second body portion 112, the third body portion 113, and the extension portion 13 may be integrally molded from a flexible material such as silicone to improve the strength.

[0107] Example 2

[0108] like Figures 8a-9cThis application provides a pulse oximeter device 100, including a probe assembly 10 and a strap assembly 20. Compared with the first embodiment, the strap hole 16 of the probe assembly 10 in this application embodiment does not penetrate the inner and outer surfaces of the extension portion 13, nor does it penetrate the inner and outer surfaces of the body portion 11. Specifically, the probe assembly 10 includes a body portion 11, a connecting portion 12, and a protective portion 14. The body portion 11 has an inner surface and an outer surface. The inner surface of the body portion 11 encloses an accommodating space 15 with an opening. The protective portion 14 is connected to the end of the body portion 11, and the connecting portion 12 is disposed on the protective portion 14 or the body portion 11, forming a strap hole 16 between the connecting portion 12 and the protective portion 14 or the body portion 11 for the strap assembly 20 to pass through. The connecting portion 12 and the strap hole 16 are located outside the protective portion 14. The probe assembly 10 may also include a detection element 19, which includes a first detection element 191 and a second detection element 192. The positions and electrical connections of the first detection element 191 and the second detection element 192 can be referred to in Embodiment 1, and will not be repeated here.

[0109] The strap assembly 20 includes a first strap body 21, a second strap body 22 and a third strap body 23. The connection relationship and structure of the first strap body 21, the second strap body 22 and the third strap body 23 of the strap assembly 20 in this embodiment can be referred to the strap assembly 20 in Embodiment 1, and will not be repeated here.

[0110] When the strap assembly 20 is attached to the probe assembly 10, the first strap 21 passes through the strap hole 16, and the first hook layer 212 at the end of the first strap 21 is detachably connected to the nap 222 of the second strap 22. The side of the first strap 21 facing the receiving space 15 is shielded by the protective part 14 and isolated from the receiving space 15. The second strap 22 is wrapped around the outer surface of the body part 11 and the protective part 14. The third hook layer 232 of the third strap 23 is detachably connected to the nap 222 of the second strap 22. This embodiment has the same technical effects as Embodiment 1, and can be referred to Embodiment 1, which will not be repeated here.

[0111] In this embodiment, the connection relationship between the protective part 14 and the main body 11 can be referred to the connection relationship between the extension part 13 and the main body 11, and the material and size of the protective part 14 can be referred to the material and size of the extension part 13, which will not be repeated here.

[0112] The structure of the body part 11 in this embodiment can be referred to the structure of the body part 11 in Embodiment 1, and will not be repeated here.

[0113] like Figures 8a-8cThe protective portion 14 includes a first protective portion 14a and a second protective portion 14b. The first protective portion 14a is fixed to one end of the main body portion 11, and the second protective portion 14b is fixed to the other end of the main body portion 11. The first protective portion 14a and the second protective portion 14b can deform to enclose the main body portion 11. When the first protective portion 14a and the second protective portion 14b deform to enclose the main body portion 11, the ends of the first protective portion 14a and the second protective portion 14b abut or partially overlap. The connecting portion 12 is provided on the outer surface of the first protective portion 14a, and the strap hole 16 is formed between the connecting portion 12 and the outer surface of the first protective portion 14a, thereby ensuring that the strap hole 16 and the receiving space 15 are blocked by the first protective portion 14a and the second protective portion 14b.

[0114] For example, the surface of the connecting portion 12 is set as an arc-shaped surface, so that the surface of the connecting portion 12 transitions smoothly, which facilitates the first strap 21 or the third strap 23 to pass through the strap hole 16 and fit tightly against the connecting portion 12. It should be noted that the structure of the top surface of the connecting portion 12 is not limited to this.

[0115] like Figures 9a-9c A groove 1112 is provided on the outer side of one end of the main body 11, and a connecting part 12 is provided on the main body 11 and located within the groove 1112. A protective part 14 and a connecting part 12 are provided at the same end of the main body 11, and the protective part 14 is connected to the inner surface of one end of the main body 11, so that the connecting part 12 and the strap hole 16 are both located outside the protective part 14. This ensures that the strap hole 16 and the receiving space 15 are blocked by the main body 11 and the protective part 14. In one case, after the first strap 21 is connected to the connecting part 12 and the second strap 22, the first strap 21 is completely located outside the protective part 14 to prevent the harder first strap 21 from protruding into the receiving space 15, so that the opening of the main body 11 is covered by the wider and less rigid second strap 22.

[0116] The pulse oximeter device provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this application. Therefore, the content of this specification should not be construed as a limitation of this application.
