Description

Technical Field

[0001] This utility model relates to the technical field of coupling agent application devices, and in particular to an automatic coupling agent sensing and dispensing device and a constant temperature device. Background Technology

[0002] Medical coupling agent is a medical product composed of water-based polymer gel. It is non-toxic and harmless to the human body, has a suitable viscosity, is non-greasy, and has good lubrication. When applied to a medical probe, it makes the probe easy to slide and unfold, and it also makes the imaging of medical ultrasound instruments clear. It is commonly used in ultrasound examinations in medical projects.

[0003] However, medical coupling agents are typically colder than human body temperature. When applied to the patient's body, the low temperature can cause discomfort, especially in cold winter months. The cold coupling agent can not only make the patient nervous but also trigger a stress response, potentially affecting the ultrasound examination. Medical coupling agents are usually packaged in deformable plastic bottles. To use them, the bottle is inverted and squeezed to expel the coupling agent. During ultrasound examinations, medical staff typically operate the computer with one hand and hold the ultrasound probe with the other. When squeezing for the coupling agent, they must use their other hand to operate the bottle. Furthermore, the coupling agent is often applied to the ultrasound probe during the examination, requiring frequent interruptions to squeeze the bottle, disrupting the flow of the ultrasound procedure. Additionally, the coupling agent may stick to the bottle, requiring separate cleaning of the hands and hindering computer operation.

[0004] Based on the above, the inventors designed a device that can continuously keep the coupling agent warm and can be used in a contactless manner, or at least a device that can be used without hands, to improve the aforementioned inconvenience for medical staff when performing ultrasound examinations. Utility Model Content

[0006] Therefore, this utility model provides an automatic coupling agent dispensing and temperature control device, comprising:

[0007] The box body includes a platform located above the support legs. There are four support legs, and side panels are connected between each pair of adjacent four support legs to form the box body.

[0029] As a preferred embodiment, the foot switch is provided with a protective cover.

[0030] The technical solution provided by this utility model has the following advantages:

[0031] 1. This utility model's automatic coupling agent dispensing and temperature control device can continuously keep the coupling agent warm and allows for contactless dispensing, bringing convenience to medical personnel during ultrasound examinations. Specifically, the device's platform is equipped with a first insulation device, which continuously keeps the coupling agent bottle at a constant temperature of 35-37℃, a temperature suitable for the human body. The coupling agent bottle, placed inside the first insulation device, has its nozzle facing downwards, passing through the bottom opening of the device and the opening on the platform, extending into the dispensing space formed by the curved protective plate. A collection tray is placed below the nozzle of the coupling agent bottle. A sensor switch is located on the inside of the support leg, a certain distance below the nozzle of the coupling agent bottle. When medical personnel need to dispense the coupling agent, they can use their hands... When a hand is extended below the nozzle, the sensor switch detects a hand and, via a PLC controller inside the support leg, controls the first electromagnetic drive device to operate. This drives the first drive rod to extend upwards and outwards, pushing the crossbar to rotate around the support rod. The crossbar then compresses the ring clamps via a conical extruder at the other end. The conical extruder inserts downwards, creating an interlocking space between the two ring clamps, causing them to squeeze inwards and tighten, thus compressing the coupling agent bottle and expelling the coupling agent from the nozzle for contactless dispensing. Once enough has been dispensed, the hand is removed from below the nozzle. The sensor switch detects the hand's departure and, via the PLC controller inside the support leg, stops the first electromagnetic drive device, halting the upward and outward extension of the first drive rod. The crossbar stops rotating, the conical extruder stops inserting downwards, and the coupling agent bottle is no longer compressed, preventing further leakage. When the PLC controller stops controlling the first electromagnetic drive device, it automatically returns to its original position. Alternatively, a spring can be used to assist in resetting the crossbar via a connecting rod. By setting parameters for the PLC controller, the first drive rod can be moved upward a specific length from its initial position each time, thereby squeezing out a specific amount of coupling agent, which facilitates control.

[0032] 2. The automatic sensing and temperature control device for coupling agent of this utility model includes a first clamp and a second clamp. One end of the first clamp and the second clamp are rotatably connected by a rotating shaft and installed on a first heat preservation device. The other end is provided with a first opening hook and a second opening hook, respectively. When they are interlocked, they form an interlocking space. When the conical extruder is inserted downward through the interlocking space, the first clamp and the second clamp clamp clamp tightly hug the middle, squeezing the coupling agent bottle located in the middle, so that the coupling agent is squeezed out.

[0033] 3. The automatic coupling agent dispensing and temperature control device of this invention also includes a second insulation device on the platform for holding the coupling agent bottle with its tip facing upwards. This position is a spare position, pre-heated for the coupling agent. When the coupling agent installed in the first insulation device is used up, the coupling agent bottle originally placed in the second insulation device can be directly installed into the first insulation device. This ensures that the temperature of the coupling agent remains essentially constant, preventing the problem of insufficient temperature rise of the coupling agent after changing the bottle. Alternatively, the temperature of the second insulation device can be set to a slightly lower temperature, such as around 25°C, to avoid excessive energy consumption.

[0034] 4. The automatic coupling agent dispensing and temperature control device of this utility model can also use a foot switch when the PLC controller cannot control the extrusion of a specific amount of coupling agent each time. The foot switch is electrically connected to the PLC controller through a wire. When the foot switch is triggered, the PLC controller controls the second electromagnetic drive device to operate continuously. The second drive rod continuously drives the pedal to rotate around the fixed rod, and then the coupling agent is continuously extruded through the connecting rod, crossbar and circumferential clamp until the foot switch is no longer triggered.

[0048] This embodiment provides an automatic coupling agent sensing and temperature control device, such as... Figure 1-8 As shown, it includes: a box body 1, the box body 1 including a platform 10, the platform 10 being located above support legs 11, the support legs 11 being four in number, the four support legs 11 being connected by side plates 12 between each pair of adjacent support legs 11, and enclosing to form the box body 1; the upper periphery of the platform 10 of the box body 1 is also provided with dust covers 7, there are two dust covers 7, which are rotatable and can be opened or closed. When opened, it is convenient to replace the coupling agent, and when closed, it can prevent dust from falling in.

[0049] The platform 10 is provided with a first heat preservation device 51. The bottom opening of the first heat preservation device 51 is opposite to the opening opened on the platform 10. The first heat preservation device 51 is suitable for placing the coupling agent bottle 6 upside down, and the tip 61 of the coupling agent bottle 6 can pass through the bottom opening of the first heat preservation device 51 and the opening opened on the platform 10. Specifically, the first heat preservation device 51 is provided with a first heating wire 96 and forms a first placement cavity 95, which is used to accommodate the coupling agent bottle 6.

[0050] An arc-shaped protective plate 13 is disposed inside the support leg 11, enclosing a space for taking out the coupling agent. A collection tray 8 is placed at the bottom, and the top of the collection tray 8 is vertically opposite to the nozzle 61 of the coupling agent bottle 6. This space isolated by the arc-shaped protective plate 13 is the space for medical personnel to take out the coupling agent. That is, when the coupling agent needs to be taken out, the medical personnel will reach their hand here, trigger the induction switch 20, and receive the coupling agent that is automatically squeezed out at this position.

[0051] An inductive switch 20 is provided at a certain distance below the nozzle 61 of the coupling agent bottle 6 on the inner side of the support leg 11; a PLC controller 91 is provided inside the housing 1, and the inductive switch 20 is electrically connected to the PLC controller 91; the inductive switch is used to sense whether there is a human hand and transmit the detection signal to the PLC controller 91, which controls the operation of the equipment to automatically extrude a set amount of coupling agent.

[0052] The platform 10 is equipped with a first electromagnetic drive device 21, which is electrically connected to the PLC controller 91. A first drive rod 22 is installed at the center of the first electromagnetic drive device 21, and a rotatable roller 94 is installed in the groove at the top of the first drive rod 22. It also includes a support rod 35, and a groove 37 is opened at the top of the support rod 35. The middle part of the crossbar 38 is rotatably installed inside the groove 37. The bottom surface of one end of the crossbar 38 rolls in contact with the roller 94 at the top of the first drive rod 22, and the other end is rotatably connected to the conical extrusion piece 41. When the first drive rod 22 moves vertically upward, the roller 94 rolls under the action of the thrust of the first drive rod 22 and the friction between it and the crossbar 38. At the same time, one end of the crossbar 38 also swings upward under the action of the thrust of the first drive rod 22. During the swing, the contact point between the lower end surface of the crossbar 38 and the outer circle of the roller 94 can move relative to each other under the influence of the force.

[0053] Two ring clamps 42 are installed above the first heat preservation device 51, opposite the middle or upper part of the coupling agent bottle 6; one end is rotatably connected, and the other end hugs each other to form an insertion space 43 for the conical extruder 41 to pass through vertically; when the conical extruder 41 is inserted downward, the two ring clamps 42 hug and squeeze inward; when the conical extruder 41 is pulled upward, the two ring clamps 42 can expand outward under the elastic action of the coupling agent bottle 6.

[0054] It also includes a fixing rod 30, which is fixedly connected between two adjacent support legs 11, and a pedal 31 is rotatably mounted on the fixing rod 30; a fixing frame 32 is provided below the platform 10;

[0055] The connecting rod 39 has one end rotatably connected to the first boss 36 on the lower surface of the crossbar 38 near the end of the tapered extruder 41, and the other end passes downward through the platform 10 and is rotatably connected to the second boss 14 on the pedal 31.

[0056] The connection point between the upper end of the connecting rod 39 and the lower end of the crossbar 38 can rotate around the middle of the crossbar 38, and the connection point between the lower end of the connecting rod 39 and the pedal 31 can rotate around the fixed rod 30; the two ends of the spring 40 are fixedly connected to the fixed frame 32 and the pedal 31 respectively.

[0057] The automatic coupling agent dispensing and temperature control device of this embodiment can both continuously keep the coupling agent warm and allow for contactless dispensing of the coupling agent, bringing convenience to medical personnel in ultrasound examinations. The platform 10 of the device housing 1 is equipped with a first temperature control device 51, which continuously keeps the coupling agent bottle 6 placed inside at a constant temperature of 35-37°C, a temperature suitable for the human body.

[0058] The coupling agent bottle 6, placed inside the first insulation device 51, has its nozzle 61 facing downwards. After passing through the bottom opening of the first insulation device 51 and the opening on the platform 10, it extends downwards, precisely into the retrieval space formed by the curved protective plate 13. A collection tray 8 is placed opposite the nozzle 61 of the coupling agent bottle 6. A sensor switch 20 is located inside the support leg 11, a certain distance below the nozzle 61 of the coupling agent bottle 6. When medical personnel need to retrieve the coupling agent, they reach their hand below the nozzle 61; upon sensing the hand, the sensor switch 20... The PLC controller 91 installed inside the support leg 11 controls the first electromagnetic drive device 21 to operate, driving the first drive rod 22 to extend upward and outward, pushing the crossbar 38 to rotate around the support rod 35. The conical extruder 41 at the other end squeezes the ring clamp 42. The conical extruder 41 inserts downward to form an interpenetration space 43 between the two ring clamps 42, causing the two ring clamps 42 to squeeze inward and tighten, thereby squeezing the body of the coupling agent bottle 6 and squeezing the coupling agent contained in the coupling agent bottle 6 from the nozzle 61 position, realizing contactless dispensing.

[0059] When the amount taken is sufficient or the set amount is extruded each time, the hand is removed from below the nozzle 61. After the sensor switch 20 senses that the hand has left, the PLC controller 91 set inside the support leg 11 controls the first electromagnetic drive device 21 to stop operating, stops driving the first drive rod 22 to extend upward and outward, the crossbar 38 no longer rotates, the conical extruder 41 no longer continues to penetrate downward, the body of the coupling agent bottle 6 is no longer under pressure, and the coupling agent no longer flows out.

[0060] When the PLC controller 91 stops controlling the first electromagnetic drive device 21, the first electromagnetic drive device 21 automatically resets, and the spring 40 can also help drive the crossbar 38 to reset via the connecting rod 39. By setting the parameters of the PLC controller 91, it is possible to control the first drive rod 22 to move upward by a specific length each time from the initial position, thereby squeezing out a specific amount of coupling agent, which facilitates control.

[0061] In this embodiment, the circumferential clamp 42 includes: a first circumferential clamp 421 having a first circumferential portion 4211, one end of which is provided with a first pivot hole 4212 and the other end with a first open hook 4213; and a second circumferential clamp 422 having a second circumferential portion 4221, one end of which is provided with two vertically opposite second pivot holes 4222 and the other end with two vertically opposite second open hooks 4223; one end of the first circumferential portion 4211 with the first pivot hole 4212 can be installed between one end of each of the two second circumferential portions 4221 with the second pivot holes 4222 respectively, and the first open hook 4213 can be installed between the two second open hooks 4223 to form the interpenetration space 43.

[0062] A first connecting handle 4214 is provided between the first open hook 4213 and the first circumferential clamp 421; two second connecting handles 4224 are provided between the two second open hooks 4223 and the second circumferential clamp 422, and a gap is formed between the two second connecting handles 4224, through which the first connecting handle 4214 and the first open hook 4213 can move back and forth.

[0063] A first fixing bolt 33 is provided on the outer side of the movable end of the pedal 31, and a second fixing bolt 34 is provided on the fixing frame 32 that is vertically opposite to the first fixing bolt 33. The spring 40 is connected between the first fixing bolt 33 and the second fixing bolt 34.

[0064] The lower surface of the crossbar 38 near the tapered extruder 41 is provided with the first boss 36, and the connecting rod 39 is rotatably mounted on the first boss 36. The other end of the connecting rod 39 is rotatably mounted on the second boss 14 above the pedal 31.

[0065] Dust covers 7 are provided on the top of the housing 1. There are two dust covers 7, which are rotatable and have an open state and a closed state.

[0066] The platform 10 is also provided with a second heat preservation device 52, which is used to hold the coupling agent bottle 6 with the nozzle 61 facing upward. Specifically, the second heat preservation device 52 is provided with a second heating wire 98 and forms a second placement cavity 97, which is used to accommodate the coupling agent bottle 6.

[0067] It also includes a foot switch 9, which is electrically connected to the PLC controller 91 via a wire; a second electromagnetic drive device 92 is provided on the lower surface of the platform 10, which is electrically connected to the PLC controller 91; a second drive rod 93 is installed at the center of the second electromagnetic drive device 92, and a roller is provided at the end of the second drive rod 93, which presses against the pedal 31.

[0068] The foot switch 9 is equipped with a protective cover 90.

[0069] When the amount of coupling agent extruded by the PLC controller 91 each time is insufficient, a foot switch 9 can be used. The foot switch 9 is electrically connected to the PLC controller 91 through a wire. When the foot switch 9 is triggered, the PLC controller 91 controls the second electromagnetic drive device 92 to operate continuously. The second drive rod 93 continuously drives the pedal 31 to rotate around the fixed rod 30, and then the coupling agent is continuously extruded through the connecting rod 39, the crossbar 38 and the clamp 42 until the foot switch 9 is no longer triggered.

[0070] The method of using the automatic coupling agent dispensing and temperature control device in this embodiment is as follows:

[0071] The coupling agent bottle 6 is placed upside down in the placement cavity 95 of the first heat preservation device 51 on the platform 10. The first heating wire 96 inside the first heat preservation device 51 forms the placement cavity 95, heating and keeping the coupling agent bottle 6 placed in the cavity warm. When medical staff need to take the coupling agent, they reach their hand under the nozzle 61. After the induction switch 20 senses the hand, it controls the first electromagnetic drive device 21 to operate through the PLC controller 91 inside the support leg 11. This drives the first drive rod 22 to extend upward and outward, pushing the crossbar 38 to rotate around the support rod 35. The conical extruder 41 at the other end squeezes the ring clamp 42. The conical extruder 41 inserts downward to form an interpenetration space 43 between the two ring clamps 42, causing the two ring clamps 42 to squeeze inward and tighten, thereby squeezing the bottle body of the coupling agent bottle 6 and squeezing the coupling agent inside the coupling agent bottle 6 out from the nozzle 61, achieving contactless retrieval.

[0072] When the amount taken is sufficient or the set amount is extruded each time, the hand is removed from below the nozzle 61. After the sensor switch 20 senses that the hand has left, the PLC controller 91 set inside the support leg 11 controls the first electromagnetic drive device 21 to stop operating, stops driving the first drive rod 22 to extend upward and outward, the crossbar 38 no longer rotates, the conical extruder 41 no longer continues to penetrate downward, the body of the coupling agent bottle 6 is no longer under pressure, and the coupling agent no longer flows out.

[0073] When the amount of coupling agent extruded by the PLC controller 91 each time is insufficient, a foot switch 9 can be used. The foot switch 9 is electrically connected to the PLC controller 91 through a wire. When the foot switch 9 is triggered, the PLC controller 91 controls the second electromagnetic drive device 92 to operate continuously. The second drive rod 93 continuously drives the pedal 31 to rotate around the fixed rod 30, and then the coupling agent is continuously extruded through the connecting rod 39, the crossbar 38 and the clamp 42 until the foot switch 9 is no longer triggered.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
