[0025] The utility model provides a thumb fitting structure for blood oxygen monitoring: it includes a first mounting splint 101, a second mounting splint 102, a light emitting diode 103, a photoelectric tube 104 and a locking module, and the locking module includes a locking cylinder 105, a locking rod 107, a holding column 109, a guide arc block 110, a holding spring 111, a sliding block 112, a limiting cylinder 113, a limiting rod 114 and a pushing spring 115.

[0026] According to this specific embodiment, the locking module is respectively connected to the first mounting clamp plate 101 and the second mounting clamp plate 102, the first mounting clamp plate 101 is provided with the light-emitting diode, and the second mounting clamp plate 102 is provided with the phototube 104. Under the action of the locking module, the distance between the first mounting clamp plate 101 and the second mounting clamp plate 102 can stably clamp the patient's fingers, and the light-emitting diode 103 and the phototube 104 are clamped at the nails and fingertips of the patient's fingers. After receiving the light emitted by the light-emitting diode 103, the phototube 104 outputs the received signal to the processor through a cable to perform blood oxygen monitoring.

[0027] Among them, the locking cylinder 105 is fixedly connected to the first mounting clamping plate 101, one end of the locking rod 107 is fixedly connected to the second mounting clamping plate 102, the other end of the locking rod 107 is slidably connected to the locking cylinder 105, the locking rod 107 has a mounting cavity 108, the locking cylinder 105 has a plurality of locking holes 106, the resisting spring 111 is arranged in the mounting cavity 108, the two ends of the resisting spring 111 are respectively connected to the resisting column 109 and the locking rod 107, and the resisting column 109 is adapted to each of the locking holes 106, the guiding arc block 110 is fixedly connected to the resisting column 109, and is located on the outer side wall of the resisting column 109, respectively pressing the first mounting clamping plate 101 and the second mounting clamping plate 102 towards the position of the fingers, The locking rod 107 and the locking cylinder 105 slide relative to each other; the arc surface of the guide arc block 110 contacts the locking cylinder 105, and the guide arc block 110 is squeezed. At this time, the supporting column 109 moves into the installation cavity 108, and the supporting spring 111 is compressed and has a rebound force. When the installation cavity 108 is connected with the locking hole 106, under the action of the supporting spring 111, the supporting column 109 and the guide arc block 110 are inserted into the corresponding locking hole 106, and the plane of the guide arc block 110 resists the locking cylinder 105. The locking cylinder 105 and the locking rod 107 can only be compressed but cannot be stretched, until the distance between the first mounting splint 101 and the second mounting splint 102 can stably clamp the patient's fingers.

[0028] Secondly, the sliding block 112 is fixedly connected to the abutting column 109 and is slidably disposed in the mounting cavity 108 . The sliding block 112 improves the stability of the abutting column 109 when moving.

[0029] At the same time, the limiting cylinder 113 is fixedly connected to the first mounting splint 101, one end of the limiting rod 114 is fixedly connected to the second mounting splint 102, the other end of the limiting rod 114 is slidably connected to the limiting cylinder 113, and the two ends of the pushing spring 115 are respectively connected to the limiting cylinder 113 and the limiting rod 114. When no monitoring is performed, under the action of the pushing spring 115, the length formed between the limiting cylinder 113 and the limiting rod 114 is the largest. Therefore, the distance between the first mounting splint 101 and the second mounting splint 102 without external contact is the largest, so that the patient's fingers can be inserted between the first mounting splint 101 and the second mounting splint 102.

[0030] When the utility model is used to monitor the patient's blood oxygen, the light-emitting diode 103 is installed on the first mounting splint 101, and the photoelectric tube 104 is installed on the second mounting splint 102. The patient's finger is inserted between the first mounting splint 101 and the second mounting splint 102, and the medical staff squeezes the first mounting splint 101 and the second mounting splint 102 toward the position of the finger, so that the locking rod 107 and the locking cylinder 105 slide relative to each other; wherein the arc surface of the guide arc block 110 contacts the locking cylinder 105, and the guide arc block 110 is squeezed, at this time, the supporting column 109 moves into the mounting cavity 108, and the sliding block 112 improves the stability of the supporting column 109 when moving, and the supporting spring 111 is compressed and has a rebound force. When the mounting cavity 108 and the locking cylinder 105 are in contact, the supporting column 109 moves into the mounting cavity 108, and the sliding block 112 improves the stability of the supporting column 109 when moving. The supporting spring 111 is compressed and has a rebound force. When the locking hole 106 is connected, under the action of the supporting spring 111, the supporting column 109 and the guiding arc block 110 are inserted into the corresponding locking hole 106, and the plane of the guiding arc block 110 resists the locking cylinder 105. The locking cylinder 105 and the locking rod 107 can only be compressed but not stretched, until the distance between the first mounting clamp 101 and the second mounting clamp 102 can stably clamp the patient's fingers, and clamp the light-emitting diode 103 and the photoelectric tube 104 at the nails and fingertips of the patient's fingers. After the photoelectric tube 104 receives the light emitted by the light-emitting diode 103, it outputs the received signal to the processor through a cable to monitor blood oxygen; thus, the patient with uncontrollable hand shaking can be stably clamped to avoid the effect of unstable clamping affecting the blood oxygen monitoring result. When no monitoring is performed, under the action of the push spring 115, the length formed between the limit cylinder 113 and the limit rod 114 is the largest, so the distance between the first mounting splint 101 and the second mounting splint 102 without external contact is the largest, so that the patient's finger can be inserted between the first mounting splint 101 and the second mounting splint 102.

[0034] The locking cylinder 105 has a placement groove 206, and the pressing assembly is arranged in the placement groove 206. The pressing assembly is used to push the guide arc block 110 and the supporting column 109 into the installation cavity 108 so as to expand the distance between the first installation clamp plate 101 and the second installation clamp plate 102, thereby removing the patient's finger.

[0035] The reset spring 201 is arranged in the placement groove 206, and the two ends of the reset spring 201 are respectively connected to the locking cylinder 105 and the pressing rod 202, and one end of the mounting plate 203 is fixedly connected to the pressing rod 202, and each of the pushing columns 204 is respectively fixedly connected to the mounting plate 203, and each of the pushing columns 204 is adapted to the corresponding locking hole 106. Pressing the pressing rod 202 drives the mounting plate 203 to move toward the locking cylinder 105, so that the pushing column 204 moves into the corresponding locking hole 106 until it contacts the guide arc block 110, and pushes the guide arc block 110 and the supporting column 109 into the mounting cavity 108, thereby expanding the distance between the first mounting splint 101 and the second mounting splint 102, thereby removing the patient's finger.

[0036] The soft pad 205 is fixedly connected to the pressing rod 202 and is located on the outer side wall of the pressing rod 202. The soft pad 205 improves the tactile feeling of medical staff.

[0037] The plane of the guide arc block 110 abuts against the locking cylinder 105, and the locking cylinder 105 and the locking rod 107 can only be compressed but not stretched; if stretching is required, the pressing rod 202 is pressed to drive the mounting plate 203 to move toward the direction of the locking cylinder 105, so that the pushing column 204 moves into the corresponding locking hole 106 until it contacts the guide arc block 110, and pushes the guide arc block 110 and the abutting column 109 into the mounting cavity 108, thereby expanding the distance between the first mounting splint 101 and the second mounting splint 102, so as to remove the patient's finger; under the action of the reset spring 201, the pressing rod 202 returns to its original position after the medical staff lets go, so as to facilitate the next press.
