Description

Technical Field

[0001] The utility model relates to the technical field of medical examination, in particular to an examination flashlight which can measure the pupil size of a patient. Background Art

[0002] In modern medical clinical work, for some patients who have suffered an accident and are in a coma or confused, medical staff will use a flashlight to observe the size of the patient's pupil to judge the patient's physical condition. However, observing the size of the patient's pupil with the naked eye has the problem of low accuracy. In order to improve the accuracy of judging the size of the patient's pupil, medical staff generally use a flashlight that can measure the patient's pupil to illuminate:

[0003] For example, a multifunctional pupil observation pen with the utility model application number CN201910496218.3 includes a functional tube, a pen tube, a connecting tube and a pen cap. A medical knife groove is provided on one side of the outer surface of the functional tube, and a medical scissors groove is provided on the other side of the outer surface of the functional tube. One end of the functional tube is threadedly connected to a light irradiation tube, and the other end of the functional tube is fixedly connected to a battery control tube. The internal thread of the battery control tube is connected to the pen tube, and one end of the pen tube is threadedly connected to a connecting tube. The outer surface of the connecting tube is threadedly connected to a pen tip tube, and the outer surface of the pen tip tube is sleeved with a pen cap. The multifunctional pupil observation pen, through the coordinated arrangement of the functional tube, the pen tube, the connecting tube, the pen cap and the light irradiation tube, enables the multifunctional pupil observation pen to have the functions of signing, cutting open the bottle mouth and lighting during use, and all the functions used are concentrated on the observation pen, which greatly reduces the volume and achieves the purpose of convenient carrying.

[0004] The pupil observation pen in the above document, although it can simultaneously have the functions of signing, cutting open the bottle mouth and lighting during use through the coordinated arrangement of the function tube, pen tube, connecting tube, pen cap and light irradiation tube, the pupil observation pen observes the pupil by directly illuminating the pupil with a lighting lamp. When the user encounters some patients who are unconscious or in a coma, it is inconvenient for the pupil observation pen to measure the patient's pupil, resulting in the user being unable to accurately judge the patient's pupil size, and then it is inconvenient to confirm the patient's physical condition. Therefore, there is a certain inconvenience in the process of use.

[0005] So we propose an examination flashlight that can measure the pupil size of patients in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide an inspection flashlight that can measure the size of a patient's pupil, so as to solve the problem raised in the above-mentioned background technology that when a user encounters some patients who are unconscious or in a coma, the pupil observation pen is inconvenient to measure the patient's pupil, resulting in the user being unable to accurately judge the patient's pupil size, and further inconvenient to confirm the patient's physical condition, so there is a certain inconvenience in the process of use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inspection flashlight capable of measuring the size of a patient's pupil, comprising a flashlight body and a switch button fixedly mounted on the flashlight body;

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5 The technical solution shown in the figure discloses a measuring mechanism in order to solve the problem that the inspection flashlight is inconvenient to measure the patient's pupil, making it inconvenient for medical staff to accurately judge the patient's physical condition by the size of the patient's pupil. The specific contents are as follows:

[0031] A flashlight body 1 and a switch button 2 fixedly mounted on the flashlight body 1, a fixed block 12 fixedly mounted on the flashlight body 1, a limit cylinder 13 fixedly mounted on the fixed block 12, a turntable 14 rotatably mounted on the fixed block 12, a measuring mechanism arranged on the turntable 14, and the measuring mechanism can measure and judge the size of the pupil through the turntable 14, the measuring mechanism includes an observation position bar 23, a light-transmitting sheet 21 nested on the turntable 14, a circular groove 16 is provided on the turntable 14, and the number of the circular grooves 16 is consistent with that of the light-transmitting sheet 21, and the position ... The flashlight body 1 is arranged directly below the light-transmitting sheet 21, a first pressing plate 17 is slidably installed on the inner side of the limiting cylinder 13, a first spring 18 is fixedly installed on the first pressing plate 17, and one end of the first spring 18 away from the first pressing plate 17 is fixedly connected to the fixing block 12, a first clamping column 19 is fixedly installed on the first pressing plate 17, and a rolling ball clamping block 20 is arranged on the first clamping column 19, a dry cell 3 is arranged inside the flashlight body 1, a pressing cover plate 4 is arranged on the flashlight body 1, a power conversion output component 5 is fixedly installed inside the flashlight body 1, and a lighting lamp 6 is fixedly installed on the power conversion output component 5;

[0032] When in use, the switch button 2 can be activated and the turntable 14 can be rotated, so that the light beam emitted by the illuminating lamp 6 passes through the light-transmitting sheet 21 and shines on the patient's pupil (the illuminating lamp 6 shines parallel light, which is a prior art and is not described in detail here). The rotating turntable 14 allows the light of the illuminating lamp 6 to pass through the light-transmitting sheet 21, and the light is irradiated into a light beam of the same size as the light-transmitting sheet 21 under the action of the light-transmitting sheet 21. At this time, the light beam can be overlapped with the patient's pupil, and then the size of the light-transmitting sheet 21 can be judged by viewing the corresponding observation position bar 23. When the size of the light beam transmitted by the light-transmitting sheet 21 does not match the size of the patient's pupil, the turntable 14 can be rotated to rotate the light-transmitting sheets 21 of different sizes to the center position of the illuminating lamp 6, so that the user can see the observation position bar 23 by viewing the observation position bar 23. The position of the observation position bar 23 is used to determine which group of light-transmitting sheets 21 is located at the center of the lighting lamp 6 (the observation position bar 23 at the bottom of each group of light-transmitting sheets 21 is provided with the corresponding measurement size of the light-transmitting sheets 21), and then the size of the patient's pupil is determined by the corresponding light-transmitting sheets 21. At the same time, when the turntable 14 rotates, because the circular groove 16 and the ball block 20 are both circular structures, when the turntable 14 rotates under human interference, the turntable 14 and the circular groove 16 will push the ball block 20 and the first clamping column 19 and the first spring 18 to contract. When the turntable 14 rotates to the next circular groove 16, the ball block 20 will automatically reset under the action of the first spring 18 and hold the circular groove 16, so that neither the circular groove 16 nor the turntable 14 will rotate.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 and Figure 6The technical solution shown in the figure discloses a pasting mechanism in order to solve the problem that the inspection flashlight needs to be held by the user in hand when in use, thereby affecting the user's operation.

[0036] The elastic skin-friendly strip 8 is brought into contact with the forehead of the user, and the raw edge Velcro 9 and the thorn edge Velcro 10 are passed through the fixed strip buckle assembly 11, and the thorn edge Velcro 10 passing through the fixed strip buckle assembly 11 is attached to the raw edge Velcro 9. At this time, the thorn edge Velcro 10 and the raw edge Velcro 9 can be fixed. At the same time, when the thorn edge Velcro 10 and the raw edge Velcro 9 are fixed, the elastic skin-friendly strip 8 and the fixing plate 7 are also fixed on the forehead of the user, so that medical staff do not need to hold the inspection flashlight in their hands when observing the patient's pupils.

[0037] Embodiment three:

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 5 The technical solution shown in the figure discloses a stabilizing mechanism in order to solve the problem that the turntable 14 may cause its own unstable rotation after long-term operation, thereby affecting the user's operation of the turntable 14. The specific contents are as follows:

[0039] The annular limit block 15 is fixedly installed on the turntable 14, and the observation position strip 23 and the annular clamping block 22 are fixedly installed on the outer side of the turntable 14

[0040] While the turntable 14 rotates, the annular limit block 15 also rotates synchronously on the fixed block 12, and the annular clamping block 22 also moves with the turntable 14. The annular limit block 15 and the annular clamping block 22 can improve the stability of the rotation of the turntable 14, so that the turntable 14 will not be skewed during rotation, and the practicality of the turntable 14 is simultaneously improved.

[0041] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
