Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and more specifically, relates to a waterproof structure integrating a knob and a button, a waterproof operation panel, and an ultrasonic diagnostic device. Background Art

[0002] With the continuous innovation of color Doppler ultrasound machine technology, it has become increasingly intelligent and portable. As an essential assistant for doctors, it will appear beside doctors and patients at any time, such as at the surgical site. Thus, in many cases, doctors will operate the control panel with blood flow or water flow at the surgical site. However, most current color Doppler ultrasound machine operation panels do not have waterproof and easy-to-clean functions or require an additional external waterproof cover. This causes blood flow and water flow to easily flow into the device during operation, leading to damage to precision electronic components and malfunction of the color Doppler ultrasound device, or even more inconvenience in operation and excessive time consumption due to the addition of a waterproof cover. If this situation occurs during surgery, it will surely result in inaccurate judgment of the patient's condition by the doctor, affecting the smooth progress of the surgery and the patient's life. At the same time, if the device cannot be operated personally due to blood or water stains during surgery and is handed over to an assistant, this will also surely affect the surgery completion time and treatment accuracy of the patient due to inaccurate information transmission and unnecessary waste of time during the communication process. Time is life. Therefore, the deficiencies and defects of color Doppler ultrasound devices without waterproof and easy-to-clean operation panels are obvious. Summary of the Invention

[0049] To further understand the content of the present invention, the present invention will be described in detail in combination with the accompanying drawings and embodiments.

[0050] Figures 1 to 4 It is a schematic diagram of the integrated structure of a button and a knob on an operating panel and a single-button structure in the prior art. Its sealing effect is poor, and the waterproof and anti-fouling functions are not good, resulting in easy inflow of blood and water into the device during operation, causing damage to precision electronic components and making the color Doppler ultrasound device inoperative.

[0051] Combined with Figures 5 to 7 , in order to solve the above problems, the present invention provides an integrated waterproof structure of a knob and a button, including a knob bracket 206 arranged in the operating panel 212. The knob bracket 206 is used to assemble the knob 200 and the inner button assembly 213 of the knob located on the same center line. The knob 200 is positioned and installed in the knob bracket 206 through a card slot opened on the operating panel 212. The operating panel 212 around the card slot protrudes to form a waterproof high wall. The knob 200 is provided with a card foot, and the knob 200 and the knob bracket 206 are fixed through the card foot, so that the knob 200 can drive the knob bracket 206 to rotate.

[0052] Specifically in this embodiment, a PCB board 20 is arranged in the operating panel 212. The PCB board 20 is provided with a knob seat for positioning and fixing the knob bracket 206. The PCB board 20 is detachably connected to the inside of the operating panel 212.

[0053] As an implementation manner, in this embodiment, the PCB board 20 is fixed in the operating panel 212 through screws 21.

[0054] The specific assembly sequence is as follows: The knob bracket 206 and the knob seat on the PCB board 20 are first positioned and fixed together, and then assembled onto the operating panel 212 and fixed with screws 21; the knob 200 is positioned and installed in the knob bracket 206 according to the designed card slot, and is firmly clamped by the card foot to prevent it from falling out. In this way, the knob 200 can drive the knob bracket 206 to rotate.

[0055] Furthermore, in this embodiment, the knob-in-button assembly 213 includes a knob-in-button body 204 , a knob-in-button body rubber coating 202 , and a knob-in-button body insert 205 , and the knob-in-button body rubber coating 202 is sleeved on the knob-in-button body 204 .

[0056] In addition, in order to further improve the sealing effect of the knob inner button body rubber coating 202, in this embodiment, a sealing rib is provided on the side of the knob inner button body rubber coating 202. The sealing rib is an annular sealing strip protruding from the surface of the knob inner button body rubber coating 202. The bulging sealing rib designed on the soft rubber side can still prevent dirt from entering and block water. For details, please refer to Figure 13 See the enlarged cross-sectional view of the raised sealing rib designed on the side of the soft rubber shell of the button inside the middle knob for understanding.

[0057] It is worth noting that, in order to make the knob inner button body rubber coating 202 and the knob inner button body 204 fit tightly together in this embodiment, the knob inner button body rubber coating 202 in this embodiment is injection-molded soft rubber.

[0058] Preferably, in this embodiment, the button body rubber coating 202 in the knob is made of TPE or PVC material. The button assembly 213 in the knob is a combination key that is integrally injection molded, and the button body rubber coating 202 is injection-molded soft rubber such as TPE, PVC, etc., which fits tightly with the button body 204 after injection molding, ensuring that after being installed in the knob bracket 206, the soft rubber will not be lifted or misaligned due to the large friction when moving up and down.

[0059] Preferably, the knob inner button body insert 205 in this embodiment is formed by integral injection molding, which can ensure the accuracy of product dimensions to ensure reliable realization of the micro switch action on the PCB board 20, while preventing the knob inner button body 204 from having a poor product surface appearance.

[0060] Furthermore, in this embodiment, a knob silicone seal ring 201 is arranged in the card slot, and the knob silicone seal ring 201 and the button body 204 in the knob are interference-fitted to form a waterproof seal. The knob silicone seal ring 201 is installed in the card slot to provide elasticity and water-proofing for the button.

[0061] As an implementation method, the knob 200 in this embodiment is protruded from its outer surface to form a high waterproof wall. In addition, in order to further improve the waterproof effect, in this embodiment, a knob inner button silicone seal ring 203 is also provided between the knob inner button body 204 and the knob inner button body insert 205. The knob inner button silicone seal ring 203 is first installed in the assembly, and this seal ring also plays an elastic and waterproof role, and then installed together with the knob bracket 206, and clamped with a clamping foot to prevent it from falling out.

[0062] It should be emphasized that in this embodiment, a ramp surface structure is arranged around the operation panel 212 in cooperation with the outer side surface of the knob 200, and the ramp surface structure is arranged along the circumferential direction of the knob 200.

[0063] In addition, in this embodiment, the overmolding 202 of the button body inside the knob is injection molded with TPU material.

[0064] The knob and button integrated waterproof structure of this embodiment has the knob 200 and the button assembly 213 inside the knob assembled on the same center line. The knob 200 can be rotated to drive the PCB board 20 to adjust parameters, and the button assembly 213 inside the knob can be pressed up and down to select the working mode. The actions of the knob 200 and the button assembly 213 inside the knob do not interfere with each other, and each independently completes its own function. After being assembled together, they each play a waterproof function to ensure the knob function, button function, waterproof function and easy cleaning function of the whole mechanism.

[0065] For the knob and button integrated waterproof structure of this embodiment, its waterproof technical solution is that after the knob 200, the button assembly 213 inside the knob and the control panel 212 are assembled, they together form a five - layer waterproof system, specifically as follows:

[0066] The first layer: The control panel 212 is designed with a high - wall waterproof structure. By using the structure of the control panel, a first water - blocking wall is designed to block the water flowing onto the control panel 212 on the panel, and using the principle that water flows to lower places, the water automatically flows outside the machine.

[0067] The second layer: The side sealing ribs of the overmolding 202 of the button body inside the knob are waterproof and anti - fouling. Here, a soft rubber such as TPU\PVC is integrally injection - molded on the outer shell of the button body 204 inside the knob, and bulging sealing ribs are designed on the side of the soft rubber to have an interference fit with the inner side surface of the knob 200. Using the elasticity and sealing property of the soft rubber, the water that may enter is blocked outside the button.

[0068] The third layer: The knob silicone sealing ring 201 is waterproof. The knob silicone sealing ring 201 and the button body 204 inside the knob are designed to have an interference fit to form a sealed waterproof structure. If the second - layer waterproof is damaged, the third layer will come into play.

[0069] The fourth layer: High - wall waterproof. By using the structure of the knob 200, a second high - wall inside is designed. The knob 200 protrudes from its outer surface to form a waterproof high - wall. Using the principle that water flows to lower places, the water automatically flows outside the machine. Similarly, if the third - layer waterproof is damaged, the fourth - layer waterproof will come into play.

[0070] The fifth layer: The button silicone sealing ring 203 inside the knob is waterproof. The button silicone sealing ring 203 inside the knob and the high - wall inside the knob 200 and the button body 204 inside the knob are designed to have an interference fit to form a sealed waterproof structure. If the fourth - layer waterproof is damaged, the fifth layer will come into play.

[0071] The integrated waterproof structure of the knob and button of this embodiment is waterproof and easy to clean, which is specifically reflected in the following aspects:

[0072] For easy cleaning, a sloped surface structure is designed around the outer side of the operating panel 212 and the knob 200 to avoid a narrow gap between the operating panel 212 and the knob 200, thereby preventing the accumulation of dirt and stains. The dirt can be easily cleaned with a rag and cleaning solution. Figure 12 005 structural design.

[0073] In addition, the knob 200 and the knob inner button assembly 213 have a large overlap distance after assembly. A knob inner button body rubber-encapsulated 202 shell made of TPU or other materials is designed outside the knob inner button body 204 shell, and a bulging sealing rib is designed on the side of the knob inner button body rubber-encapsulated 202 soft rubber shell to cooperate with the inner wall of the knob 200, which prevents dirt from entering the internal space and allows them to float on the surface space. Similarly, a rag and cleaning solution can be used to easily clean out the dirt. Figure 13 003 structural design.

[0074] Furthermore, in order to facilitate cleaning, the materials of each component are carefully selected in this embodiment. The knob 200 and the operation panel 212 are injection molded using ABS+PC alloy material. The ABS+PC alloy material combines the advantages of ABS material and PC material. It has the advantages of ABS material being unaffected by water, alkali, inorganic salts and various acids and being resistant to UV light, and the characteristics of PC material being able to withstand steam, cleaning agents, heating and high-dose radiation sterilization without yellowing or degradation of physical properties. At the same time, its ultra-hard texture and wear resistance allow users to clean it with confidence without damaging its appearance.

[0075] The button body rubber coating 202 in the knob is made of TPU material injection molding. This material has excellent elasticity, ultra-high wear resistance, high and low temperature resistance, oxidation resistance, water resistance, oil resistance and chemical resistance, and is non-toxic, non-allergic, non-locally irritating and non-pyrogenic, so it is widely used in medical products.

[0076] The invention discloses a waterproof structure integrating a knob and a button, which utilizes a variety of waterproof principles and product manufacturing technologies, has a simple and compact structure, and has a very reliable waterproof effect. Meanwhile, the structure and size are designed to facilitate user cleaning in consideration of the coagulation and scaling of blood stains and dirt, so that the color ultrasound equipment operation panel realizes the waterproof function and easy-to-clean function of the operation panel on the existing appearance and mechanical buttons.

[0077] In addition, this embodiment also provides a waterproof operation panel, which includes the above-mentioned integrated waterproof structure of the knob and the button, and also includes a button waterproof structure independently arranged on the operation panel 212. Combining Figure 8 and Figure 11 , after the button assembly 214 is installed into the operation panel 212, the button assembly 214 is pressed up and down to trigger the micro switch on the PCB board 20 to work, realizing the functions of key pressing, waterproofing and easy cleaning.

[0078] Specifically in this embodiment, the button waterproof structure includes a button assembly 214 installed on the PCB board 20. The button assembly 214 includes a button body 207, a button body insert 208 and a button silicone sealing ring 209. The button silicone sealing ring 209 is in interference fit with the button body 207 to form a sealed waterproof structure.

[0079] Furthermore, in this embodiment, the button waterproof structure also includes a panel silicone sealing ring 210 and a panel silicone sealing ring cover plate 211. The panel silicone sealing ring 210 is fixed to the operation panel 212 through the panel silicone sealing ring cover plate 211.

[0080] As an implementation manner, in this embodiment, the panel silicone sealing ring cover plate 211 is fixed on the operation panel 212 by screws 21.

[0081] The assembly sequence of a waterproof operation panel in this embodiment is as follows:

[0082] First, the panel silicone sealing ring 210 is installed into the panel silicone sealing ring cover plate 211, then the panel silicone sealing ring cover plate 211 is fixed into the operation panel 212 with screws 21. The button silicone sealing ring 209 is installed into the button assembly 214 to play an elastic and water-blocking role. The button assembly 214 and the button silicone sealing ring 209 are installed on the operation panel 212 together and are stuck by hooks to prevent them from falling out.

[0083] Preferably, in this embodiment, the button body 207 and / or the operation panel 212 are injection-molded from an ABS+PC alloy material. The ABS+PC alloy material combines the advantages of ABS material and PC material, which has been discussed above and is the same here.

[0084] For a waterproof operation panel in this embodiment, the waterproof technical solution of the button waterproof structure independently arranged on the operation panel 212 is as follows: after the panel silicone sealing ring 210, the panel silicone sealing ring cover plate 211, the button assembly 214 and the operation panel 212 are assembled, they form three waterproof systems, specifically:

[0085] The first layer: High-wall waterproofing is designed on the operation panel 212. A first water-blocking wall is designed using the high-wall structure on the operation panel 212 to block the water flowing onto the operation panel 212 on the panel, and using the principle that water flows to lower places to make the water automatically flow outside the machine.

[0086] The second layer: The button silicone ring 209 is waterproof. The button silicone ring 209, the button body 207, and the operation panel 212 are designed to form an interference fit to achieve sealed waterproofing. If the first layer of waterproofing is damaged, the second layer will come into play.

[0087] The third layer: The panel silicone sealing ring cover plate 211 fixes the panel silicone sealing ring 210 to the operation panel 212 with screws 21. The panel silicone sealing ring 210, the panel silicone sealing ring cover plate 211, and the operation panel 212 are designed to form an interference fit to achieve sealed waterproofing. If the second layer of waterproofing is damaged, the third layer will come into play.

[0088] The button waterproofing structure of this embodiment has the effect of being easy to clean while waterproofing, specifically manifested as:

[0089] For easy cleaning, a ramp surface structure is designed around the outer side of the cooperation between the operation panel 212 and the button body 207, which avoids the narrow gap at the joint of the two parts of the operation panel 212 and the button body 207 and prevents the accumulation and hiding of stains. Then it is very easy to clean the dirt with a rag and cleaning solution. Specifically, it can be combined with the structure design at 006 in the attached Figure 14 drawing.

[0090] A waterproof operation panel of the present invention includes the above-mentioned integrated waterproof structure of the knob and the button, and also includes a button waterproofing structure independently provided on the operation panel. The two buttons are independently provided and both have the functions of waterproofing and anti-fouling, improving the adaptability of the device.

[0091] In addition, this embodiment also provides an ultrasonic diagnostic device, which adopts the above-mentioned waterproof operation panel, has the characteristics of waterproofing, anti-fouling and easy cleaning, can be used in various places such as the operation site, provides convenience for doctors and other users to operate at any time, greatly improves work efficiency, wins precious time for operations and others, and provides a little more guarantee for saving lives.

[0092] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
