Description

Technical Field

[0001] The invention belongs to the technical field of medical devices and relates to a detector, in particular to a handheld anesthesia plane detector. Background Art

[0002] Regional nerve block and spinal anesthesia are currently widely used in various types of small and medium-sized operations, postoperative analgesia, and surgery for elderly high-risk patients who are intolerant of general anesthesia. They are also commonly used and important anesthesia methods. They have the characteristics of less trauma, fewer side effects, low requirements for instruments and sites, and low cost. Timely and accurate understanding of the range of the anesthetic block plane is not only a very important part of local anesthesia operations, but also an indicator for judging whether local anesthesia is successful.

[0003] After searching, for example, Chinese patent documents disclose a local anesthesia detector [Application No.: CN201320197613.X; Publication No.: CN203153739U]. This local anesthesia detector includes a syringe, which is characterized in that a support arm is provided at the front end of the syringe, a rod is provided at the front end of the support arm, a ring is provided on the rod, a positioning mark is provided at the upper end of the ring, and a hook is provided at the lower end of the ring.

[0004] The detector disclosed in the patent can only determine the patient's anesthesia status by asking the patient about his or her pain sensation through acupuncture. For example, when anesthetizing the forearm nerves of the arm, after anesthesia, medical staff need to determine each part one by one, and the patient also needs to answer one by one. The operation is cumbersome, which consumes a lot of time and brings inconvenience to medical staff. In addition, acupuncture can easily cause harm to patients. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a handheld anesthesia plane detector, which uses the principle of thermal imaging to display the temperature of the anesthesia site, thereby facilitating medical staff to understand the patient's anesthesia status.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A handheld anesthesia plane detector, comprising a thermal imaging thermometer body, a temperature measuring lens body, a display screen and connecting wires, wherein a grip is fixed to the bottom of the thermal imaging thermometer body, an arc rod is fixed to one side of the grip, a plurality of operation buttons are arranged on the surface of the grip, a sleeve is arranged on the rear side of the thermal imaging thermometer body, and the temperature measuring lens body is arranged inside the sleeve, a box body is bolted to the back of the thermal imaging thermometer body, a connecting plate is bolted to the front of the sleeve, a rotating column is bolted to the top of the connecting plate, and the bottom and inside of the box body are connected to the connecting plate. The first bearing seat and the second bearing seat are respectively fixed, the top end of the rotating column extends to the inside of the box body, and the rotating column is respectively fixed to the inner ring of the first bearing seat and the second bearing seat, a positioning mechanism is provided on the top of the box body, a sleeve rod is bolted to the front of the thermal imaging thermometer body, a movable rod is slidably connected to the inner wall of the sleeve rod, an anti-collision block is bonded to the front of the movable rod, a shock-absorbing spring is installed at the other end of the movable rod, and the other end of the shock-absorbing spring is fixedly installed to the inner wall of the sleeve rod, and a fixing card is bolted to the other side of the back of the thermal imaging thermometer body.

[0008] The working principle of the present invention is: the medical staff holds the gripping rod with one hand and holds the sleeve with the other hand to start the detector and control it through the operation button. The operation button is arranged on the surface of the gripping rod, which is convenient for the medical staff to operate with one hand. Then, the lens is aimed at the anesthetized part of the patient, such as the anesthetized part is the patient's forearm. The detector can be held and moved parallel to the arm in space so that the patient's arm is located under the lens of the detector. Since the temperature of human tissue after anesthesia will be higher than other parts, the temperature displayed by thermal imaging can be used to judge the anesthesia status of different positions of the patient's arm. The sleeve is rotated, and it can rotate under the action of the connecting plate, the rotating column, the first bearing seat and the second bearing seat. Then, the sleeve enters the interior of the fixed card, and the anti-collision block first contacts the ground for preliminary shock absorption. At the same time, the movable rod contracts toward the inside of the sleeve rod and makes the shock-absorbing spring in a compressed state. The shock-absorbing spring absorbs shock during the compression process.

[0009] The positioning mechanism comprises a positioning bolt, a thread groove and a friction pad, wherein the friction pad is arranged on the top of the rotating column, the thread groove is arranged through the top of the box body, and the positioning bolt is threadedly connected with the inner wall of the thread groove.

[0010] The above structure is adopted to prevent the sleeve and the temperature measuring lens body from rotating randomly after being folded or unfolded.

[0011] The surface of the top of the friction pad is rough, and the material of the friction pad is wear-resistant rubber.

[0012] The above design is adopted to increase the friction between the friction pad and the positioning bolt, thereby improving the positioning effect.

[0013] A connecting piece is fixed on the top of the sleeve, and a closing cover is hinged on the top of the connecting piece.

[0014] The above structure is used to prevent the temperature measuring lens body from being exposed to the outside and contaminated with a lot of dust when idle.

[0015] A first magnet is embedded on the surface of the closing cover, and a second magnet is embedded on the surface of the sleeve at one side away from the connecting plate, and the first magnet and the second magnet cooperate with each other for use.

[0016] The above structure is used to firmly fix the closing cover.

[0017] A lever is fixed on the top of the closing cover, and the top end of the lever is arranged in an arc shape.

[0018] The above structure makes it easy to open or close the closure cover.

[0019] A first through hole is provided on the surface of the rotating column and located between the first bearing seat and the second bearing seat, a second through hole is provided on the front of the box body, and connecting wires pass through the first through hole and the second through hole respectively.

[0020] The above structure is used to pass the connecting wires.

[0021] The number of the sleeve rods is four and they are respectively distributed at the four corners of the front side of the thermal imaging thermometer body. The anti-collision block is spherical in shape and is made of shock-absorbing rubber.

[0022] The above design makes the protection range wider and improves the protection effect.

[0023] The inner wall of the fixing card is in a semicircular arc shape, and the fixing card is made of elastic plastic.

[0024] The above design is adopted to improve the fixing effect of the fixing card.

[0025] Slide grooves are provided on both sides of the inner cavity of the sleeve rod, and sliding blocks are fixed on both sides of the movable rod, and the sliding blocks are slidably connected to the inner walls of the slide grooves.

[0026] The above structure is adopted to prevent the shock absorbing spring from being stretched.

[0027] The thermal imaging thermometer body has a storage component and an analysis module. The storage component is used to store thermal imaging images, and the analysis module can perform temperature comparison analysis on thermal imaging images taken before and after and display them.

[0028] Compared with the existing technology, this handheld anesthesia plane detector has the following advantages:

[0029] 1. The present invention uses the principle of thermal imaging to display the temperature of the patient's anesthetized area, which is convenient for medical staff to understand the patient's anesthesia status. There is no need to perform acupuncture on the patient to avoid harm to the patient. It is also convenient for medical staff to operate it by hand, and the lens can be folded after use for easy storage. It also has a protective function to prevent one side of the display screen from directly contacting the ground when it falls, which solves the problem that some existing local anesthesia detectors use acupuncture to understand the patient's anesthesia status, which is not only inconvenient to operate but also easy to cause harm.

[0030] 2. Through the arrangement of the positioning bolt, the thread groove and the friction pad, after the sleeve is folded or unfolded, the positioning bolt is rotated, and it moves downward under the action of the thread until the bottom end of the positioning bolt fits with the friction pad, thereby preventing the rotating column from rotating under the action of friction force, so as to prevent the sleeve and the temperature measuring lens body from rotating at will after being folded or unfolded.

[0031] 3. Through the arrangement of the first magnet and the second magnet, after the closing cover is closed, the first magnet and the second magnet can be attracted to each other and firmly fix the closing cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1 - Figure 5 As shown, the handheld anesthesia plane detector includes a thermal imaging thermometer body 1, a temperature measuring lens body 2, a display screen 3 and a connecting wire 11. A grip 4 is fixed to the bottom of the thermal imaging thermometer body 1, an arc rod 5 is fixed to one side of the grip 4, and a plurality of operation buttons 6 are arranged on the surface of the grip 4. A sleeve 7 is arranged on the rear side of the thermal imaging thermometer body 1, and the temperature measuring lens body 2 is arranged inside the sleeve 7. A box body 8 is bolted to the back of the thermal imaging thermometer body 1, a connecting plate 9 is bolted to the front of the sleeve 7, and a rotating column 10 is bolted to the top of the connecting plate 9. A first bearing seat 12 and a second bearing seat 13 are fixed to the bottom and the inside of the box body 8 respectively. The top of the rotating column 10 extends to the inside of the box body 8, and the rotating column 10 is fixed to the inner rings of the first bearing seat 12 and the second bearing seat 13 respectively. A positioning mechanism 14 is arranged on the top of the box body 8. A sleeve rod 16 is bolted on the surface, and a movable rod 17 is slidably connected to the inner wall of the sleeve rod 16. An anti-collision block 18 is bonded to the front of the movable rod 17. A shock-absorbing spring 19 is installed at the other end of the movable rod 17, and the other end of the shock-absorbing spring 19 is fixedly installed to the inner wall of the sleeve rod 16. A fixing card 15 is bolted on the other side of the back of the thermal imaging thermometer body 1. The present invention uses the principle of thermal imaging to display the temperature of the patient's anesthesia site, which is convenient for medical staff to understand the patient's anesthesia status, without acupuncture of the patient, to avoid harm to the patient, and also convenient for medical staff to carry out hand-held operation, and the lens can be folded after use for easy storage, and it has a protective function to prevent one side of the display screen 3 from directly contacting the ground when it falls, solving the problem that some existing local anesthesia detectors use acupuncture to understand the patient's anesthesia status, which is not only inconvenient to operate but also easy to cause harm.

[0040] The positioning mechanism 14 includes a positioning bolt 141, a threaded groove 142 and a friction pad 143. The friction pad 143 is arranged at the top of the rotating column 10. The threaded groove 142 is arranged through the top of the box body 8. The positioning bolt 141 is threadedly connected to the inner wall of the threaded groove 142. In this embodiment, through the arrangement of the positioning bolt 141, the threaded groove 142 and the friction pad 143, after the sleeve 7 is folded or unfolded, the positioning bolt 141 is rotated and moves downward under the action of the thread until the bottom end of the positioning bolt 141 fits with the friction pad 143, thereby preventing the rotating column 10 from rotating under the action of friction force, so as to prevent the sleeve 7 and the temperature measuring lens body 2 from rotating at will after being folded or unfolded.

[0041] The surface of the top of the friction pad 143 is roughened, and the material of the friction pad 143 is wear-resistant rubber. In the present embodiment, this design makes the surface of the friction pad 143 rougher, thereby increasing the friction between the friction pad 143 and the positioning bolt 141 and improving the positioning effect.

[0042] A connecting member 20 is fixed to the top of the sleeve 7, and a closing cover 21 is hinged above the connecting member 20. In the present embodiment, through the arrangement of the connecting member 20 and the closing cover 21, the connecting member 20 can fix the closing cover 21 and enable the closing cover 21 to rotate, while the closing cover 21 can close the temperature measuring lens body 2 to prevent it from being exposed to the outside and contaminated with a lot of dust when idle.

[0043] A first magnet 22 is embedded in the surface of the closing cover 21, and a second magnet 23 is embedded in the surface of the sleeve 7 on the side away from the connecting plate 9, and the first magnet 22 and the second magnet 23 are used in conjunction with each other. In this embodiment, through the arrangement of the first magnet 22 and the second magnet 23, after the closing cover 21 is closed, the first magnet 22 and the second magnet 23 can be attracted to each other and firmly fix the closing cover 21.

[0044] A lever 24 is fixed to the top of the closing cover 21 , and the top of the lever 24 is arranged in an arc shape. In this embodiment, the setting of the lever 24 allows medical personnel to rotate the closing cover 21 to open or close the closing cover 21 .

[0045] A first through hole 25 is provided on the surface of the rotating column 10 and located between the first bearing seat 12 and the second bearing seat 13, a second through hole 26 is provided on the front of the box body 8, and the connecting wire 11 passes through the first through hole 25 and the second through hole 26 respectively. In this embodiment, through the setting of the first through hole 25 and the second through hole 26, the connecting wire 11 can pass through the first through hole 25 and the second through hole 26 to enter the interior of the thermal imaging thermometer body 1, thereby connecting the temperature measuring lens body 2 with the thermal imaging thermometer body 1.

[0046] There are four groups of sleeve rods 16, which are respectively distributed at the four corners of the front side of the thermal imaging thermometer body 1. The anti-collision block 18 is spherical as a whole, and the material of the anti-collision block 18 is shock-absorbing rubber. In the present embodiment, this design enables the four corners of the front side of the thermal imaging thermometer to be provided with protective measures, so that the protection range is wider and the protection effect is improved.

[0047] The inner wall of the fixing card 15 is semicircular and made of elastic plastic. In this embodiment, this design allows the inner wall of the fixing card 15 to better fit the surface of the sleeve 7, thereby improving the fixing effect of the fixing card 15.

[0048] Slide grooves 28 are provided on both sides of the inner cavity of the sleeve rod 16, and sliders 27 are fixed on both sides of the movable rod 17, and the sliders 27 are slidably connected to the inner walls of the slide grooves 28. In this embodiment, through the setting of the slide grooves 28 and the sliders 27, the movable rod 17 can drive the sliders 27 to move on the inner walls of the slide grooves 28 during the movement, thereby achieving the effect of limiting the movement range of the movable rod 17 and preventing the shock-absorbing spring 19 from being stretched.

[0049] The shooting principle of the present invention is as follows: when working, the medical staff holds the grip 4 with one hand and the sleeve 7 with the other hand to start the detector and operate it through the operation button 6. The operation button 6 is arranged on the surface of the grip 4, which is convenient for the medical staff to operate with one hand. Then, the lens is aimed at the anesthetized part of the patient. For example, the anesthetized part is the patient's forearm. The detector can be held and moved parallel to the arm in space so that the patient's arm is located under the lens of the detector. Since the temperature of human tissue after anesthesia will be higher than other parts, the anesthesia status of different parts of the patient's arm can be judged by the temperature displayed by thermal imaging. There is no need to use acupuncture, the operation is more convenient, and it will not cause harm to the patient. After use, the positioning bolt 141 is rotated to move it upward. Move until it is out of contact with the friction pad 143, then rotate the closing cover 21 to close it, and rotate the sleeve 7, which can be rotated under the action of the connecting plate 9, the rotating column 10, the first bearing seat 12 and the second bearing seat 13, and then the sleeve 7 enters the interior of the fixing card 15, and then rotates the positioning bolt 141 to make it close to the surface of the friction pad 143, thereby completing the folding of the lens end for easy storage. If the detector falls with one side of the display screen 3 facing downward, the anti-collision block 18 will first contact the ground for preliminary shock absorption, and at the same time the movable rod 17 will contract toward the inside of the sleeve rod 16, and the shock-absorbing spring 19 will be in a compressed state. The shock-absorbing spring 19 absorbs shock during the compression process, thereby avoiding contact between the display screen 3 and the ground to prevent damage.

[0050] The thermal imaging thermometer body 1 also has a storage component and an analysis module. The storage component is used to store thermal imaging images, and the analysis module can compare and analyze the temperature of the thermal imaging images taken before and after and display them. That is, when in use, the unanesthetized body is first photographed and the temperature is displayed, and then the image is photographed again after anesthesia. When the image taken again is compared with the image taken before anesthesia, the color display is performed only when the temperature rises, which can more clearly display the anesthesia area, making it easier for medical staff to understand the patient's anesthesia condition.

[0051] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
