Description

Technical Field

[0001] The invention relates to the technical field of body temperature detection, and in particular to a device for assisting patients with arm weakness in measuring axillary body temperature. Background Art

[0002] Mercury thermometers are widely used clinically due to their high accuracy, low price and small size. At present, when the mercury thermometer is placed under the patient's armpit to measure body temperature, the patient is required to keep his arm clamped so that the thermometer is in full contact with the patient's armpit to ensure the effectiveness of the temperature measurement. However, some patients have weak arms and are unable to clamp their arms when measuring body temperature, which results in the mercury thermometer being clamped too loosely, resulting in inaccurate measurement results or slipping and breaking. Once the mercury thermometer breaks, the broken thermometer and the leaking mercury can easily cause harm to the patient. Therefore, a device is proposed to assist patients with weak arms in measuring armpit temperature.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As shown in Figures 1-5, a device for assisting patients with arm weakness in measuring axillary body temperature comprises a shell 1, and the two ends of the rear side of the shell 1 are fixedly connected with chest straps 2 that are bonded to each other, and a clamping structure that performs opposite movements is arranged in the shell 1, and the ends of the clamping structure are fixedly connected with fixing straps 5 for restraining the arm, wherein any one of the fixing straps 5 is provided with a detachable clamping structure for fixing a thermometer, and the shell 1 is provided with a limiting device for fixing the clamping device.

[0025] Specifically, a curved surface is provided on the side of the shell 1 close to the body, so that the shell 1 fits the body better; the width of the rear chest strap 2 is consistent with the height of the shell 1, and the surfaces where the two rear chest straps 2 contact each other are sewn with Velcro that adheres to each other. In order to ensure the comfort of the patient when using it, the rear chest strap 2 is made of breathable and elastic fabric; the end of the clamping structure provided in the shell 1 extends out of one side of the shell 1, and the two end positions are in an upper and lower parallel state; the diameter of an average person's arm is generally in the range of 2.5 cm to 5 cm. In order to ensure that the length of the fixing belt 5 is suitable for most people, the length of the fixing belt 5 is selected to be 12 cm; in order to ensure the blood circulation when restraining the patient's arm, the The fixing belt 5 is made of breathable and elastic fabric, and Velcro is sewn on the front and back sides of the fixing belt 5 to fix the patient's arm. By installing the fixing belt 5 at the end of the clamping structure, any arm of the patient can be clamped to achieve the state of clamping the thermometer, and it is also suitable for clamping measurements on patients with different arm widths. By detachably placing the clamping structure for fixing the thermometer at any position of the fixing belt, it is convenient for medical staff to take the thermometer for reading at any time, and the position of the thermometer is further fixed to prevent some patients from having a distance between their upper arms and chests. By setting a limiting structure, the patient's arm can be fixed after being restrained to prevent the patient from accidentally breaking free.

[0026] like Figure 1 and Figure 4 As shown, an I-shaped cavity is provided in the shell 1, and a clamping structure is provided in the cavity. The clamping structure includes two racks 4, a connecting tube 7 and a gear 8. The two racks 4 are arranged up and down in the transverse cavity. The connecting tube 7 is rotatably connected in the shell 1. One end of the connecting tube 7 facing the cavity is fixedly connected to a gear 8, and the gear 8 is meshed with the upper and lower racks 4.

[0027] Specifically, the I-shaped cavity includes two upper and lower parallel transverse through-cavities and a transverse cavity connected to the two transverse through-cavities; the ends of the two racks 4 are inserted into the upper and lower transverse through-cavities facing each other, and in order to prevent the rack 4 from shifting during movement, a boss 6 is fixedly connected to the rack 4 at a position relative to the opposite surface of the tooth block, and the upper and lower side surfaces of the inner wall of the shell 1 are provided with sliding grooves, and the boss 6 is slidably connected in the sliding grooves; the rack 4 is a flexible, highly stable plastic; the outer side surface of the shell 1 is provided with an opening, which is connected to the transverse cavity, and the outer ring of the bearing is fixedly connected in the opening, and the inner ring of the bearing is fixedly connected to the outer wall of the connecting tube 7; the gear 8 is in the middle position of the two racks 4, and when the gear 8 is rotated, the gear 8 meshes with the upper and lower racks 4 and drives the racks 4 to move toward or away from each other.

[0028] like Figure 3As shown, the limiting device includes a rotating rod 9, a connecting block 10, a clamping block 12 and a protrusion 13. The rotating rod 9 is slidably connected in the connecting tube 7, the connecting block 10 is fixedly connected to one end of the rotating rod 9, the clamping block 12 is fixedly connected to the outer surface of the other end of the rotating rod 9, and the protrusions 13 are circumferentially arranged on the end face of the rotating rod 9.

[0029] Specifically, one end of the rotating rod 9 passes through the connecting tube 7, and the length of the rotating rod 9 is greater than the distance from the outer surface of the shell 1 to the side wall of the cavity; the number of the blocks 12 is four and they are evenly distributed on the rotating rod 9, and the end surface of the gear 8 is provided with a convex groove 11 that matches the block 12. The rotating rod 9 is pulled outward to make the block 12 engage with the convex groove 11, and the rotating rod 9 is rotated to make the gear 8 rotate and engage with the rack 4; a groove 14 is provided on the side wall of the cavity, and the groove 14 cooperates with the protrusion 13, and the rotating rod 9 is pushed inward, and the protrusion 13 is inserted into the corresponding groove 14 to limit the rotating rod 9, and when the protrusion 13 is completely inserted into the groove 14, the block 12 does not completely disengage from the convex groove 11, so that The connecting tube 7 is limited at the same time to prevent the fixing belt 5 from driving the rack 4 to move and losing the effect of binding the arm when the external force on the rotating rod 9 is lost due to the movement trend of the human arm in a relaxed state. In order to ensure that the gear 8 does not rotate while limiting the rotating rod 9, the thickness of the block 12 is greater than the distance from the side wall of the cavity to the end face of the gear 8. When the protrusion 13 contacts the groove 14, a part of the block 12 is in the convex groove 11 (the thickness of the block 12 is greater than the depth of the convex groove 11), so that the gear 8 does not rotate. In order to ensure that it adapts to different people's shoulder widths so that the arms of patients with different shoulder widths can be clamped and fixed at any position, the number of protrusions 13 and grooves 14 is as large as possible, and they are evenly distributed in a ring shape.

[0030] like Figure 2 As shown, a retaining ring 18 located in the connecting tube 7 is fixedly connected to the rotating rod 9 , and the retaining ring 18 is fixedly connected to the connecting tube 7 via a spring 17 .

[0031] Specifically, the diameter of the rotating rod 9 is smaller than the inner diameter of the connecting tube 7, and the outer diameter of the retaining ring 18 is consistent with the inner diameter of the connecting tube 7; when in the initial state, the spring 17 is in a free state or in a slightly squeezed state, the block 12 is partially engaged with the convex groove 11, and the protrusion 13 is completely engaged in the groove 14, that is, the gear 8 and the rack 4 are in a locked state; when it is necessary to adjust the tightness of the arm binding with the fixing belt 5, the rotating rod 9 is pulled outward by pulling the connecting block 10. When the block 12 contacts the side wall of the convex groove 11, the protrusion 13 is completely disengaged from the groove 14, and the spring 17 is further compressed. Then, the rotating rod 9 is rotated through the connecting block 10, and the gear 8 is driven to rotate under the cooperation of the block 12 and the convex groove 11, so that the gear 8 drives the rack 4 meshing with it to move laterally.

[0032] like Figure 5 As shown, the clamping structure includes a steel clamp 19, a transverse tube 15 and a sponge block 16, the steel clamp 19 is clamped on the fixing belt 5, the transverse tube 15 is fixedly connected to the side of the steel clamp 19, the sponge block 16 is fixedly connected in the transverse tube 15, and a through hole for placing a thermometer is provided in the sponge block 16.

[0033] Specifically, the steel clip 19 is made of a steel sheet with good elasticity. In order to ensure safety during use, a layer of cut-resistant cloth is wrapped on the outside of the steel clip 19; the width of the opening of the steel clip 19 when it is in the initial state is smaller than the thickness of the fixing belt 5; a plug hole is provided in the sponge block 16, and the cross-sectional size of the plug hole is smaller than the diameter of the thermometer, so that the sponge block 16 can better wrap the thermometer; by providing the steel clip 19, it is convenient for medical staff to use the thermometer at any time, and the position of the steel clip 19 can also be adjusted according to different patients to make the measurement more accurate.

[0034] The working process of the device for assisting patients with arm weakness to measure axillary body temperature provided by the present invention is as follows:

[0035] Insert the thermometer into the sponge block 16, and wrap the two chest straps 2 around the back to be bonded and fixed. The medical staff fixes the fixing belt 5 on one arm or both arms according to the actual situation of the patient, inserts the steel clip 19 into the fixing belt 5 and adjusts it to the position of the armpit, rotates the rotating rod 9, and the gear 8 is meshed with the rack 4. The two racks 4 move towards each other, and the inner side of the arm gradually fits with the chest until the thermometer is clamped. Push the rotating rod 9 inward until the protrusion 13 is stuck in the slot 14. At this time, the rubber protrusion is stuck in the sink, and the timing is released;

[0036] Pull the rotating rod 9 outward, the spring 17 rebounds and returns to the initial state, the clamping block 12 is clamped into the convex clamping groove 11, and the rotating rod 9 is rotated counterclockwise.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
