Description

Technical Field

[0001] The present application relates to medical equipment technology, and in particular to an automatic coating device for a medical ultrasonic body surface probe. Background Art

[0002] Ultrasound examination is a non-invasive, radiation-free, real-time medical diagnostic method that is widely used in clinical practice. It has the advantages of low cost and easy operation. Ultrasound waves are transmitted into the human body through an ultrasound probe, and images are generated based on the signals reflected by human tissue to help doctors diagnose diseases. During ultrasound examination, in order to ensure the transmission of signals, a layer of coupling agent is usually applied between the ultrasound probe and the patient's skin. In this way, the probe can obtain clear images and accurately reflect the patient's internal conditions.

[0003] However, in current clinical operations, direct contact between ultrasound probes and patients can easily lead to cross infection. After each examination, medical staff usually use toilet paper to wipe the coupling agent on the probe, but this practice is not only cumbersome but also lacks effective disinfection measures. In addition, after re-applying the coupling agent, medical staff need to reprocess the probe for the next patient. This operation process not only wastes time, but also easily spreads bacteria and viruses between patients, affecting the hospital's infection control.

[0004] In order to prevent cross infection and avoid contamination of ultrasound probes, several disposable ultrasound probe isolation sleeves or isolation membranes (latex, TPU, PE, etc.) have appeared on the market in recent years. Many hospital ultrasound departments have used them in clinical examinations. The disposable ultrasound probe isolation sleeves can theoretically effectively isolate the probe and the patient's body surface, block the spread of bacteria and viruses, and ensure hygiene and safety. However, there is currently no suitable solution for this product in clinical practice due to specific operations. Many medical staff routinely use their hands to cover and cover the patient, and then remove and tear the membrane by hand. The doctor's gloves have multiple contacts with the infected person and the isolation sleeve, and there is a transmission channel. Therefore, it is impossible to completely isolate and block the cross infection of bacteria and viruses. This not only wastes time and consumes additional resources, but also fails to fully achieve the purpose of product design and use.

[0005] Therefore, in order to solve the above problems, there is an urgent need for an ultrasonic probe film coating device that can automatically and independently complete the process, which can not only ensure the hygiene of the probe, but also improve work efficiency, avoid cross infection, and meet the infection control requirements of the hospital. This device will solve the difficulties and defects in the above-mentioned use process, partially reduce the tedious work of medical staff, and ensure the safety of patients' visits.

[0025] In order to make the content of this application easier to understand, the technical solutions in the embodiments of this application will be described clearly and completely in conjunction with the drawings in the embodiments of this application. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the attached drawings.

A rotating bracket 14 is fixedly provided on one side wall of the inner part of the protective shell 1. The film roll 2 is a single-sided low-viscosity ultrasonic isolation film. The film roll 2 is mounted on the rotating bracket 14 through a nut, and a cover plate 15 is provided on the protective shell 1 at a position above the corresponding film roll 2, so as to facilitate the replacement of the film roll 2 and the maintenance of the inside of the device; a support frame 3 is fixedly provided on the inner bottom surface of the protective shell 1 at a position on the side where the film roll 2 is pulled out, a film support plane 8 is provided on the top of the support frame 3, a film transmission channel 9 is provided between the film support plane 8 and the inner top surface of the protective shell 1, a transmission component 4 is provided in the film transmission channel 9, and the transmission component 4 is used to support and transmit a layer of film 21 of the film roll 2, and pulling components are provided on both sides of the film 21 on the film support plane 8. The pulling components 5 on both sides are used to pull the end of the film 21 to move along the transmission component 4. A probe insertion port 10 is penetrated through the top of the protective shell 1, and a coating port 11 is penetrated through the film support plane 8 at the position corresponding to the probe insertion port 10. Transition fillet plates 16 are provided on the surrounding sides of the coating port 11 to prevent the film 21 from being damaged during coating; a film pressing component 6 is installed on the bottom surface of the inner part of the protective shell 1 at a position directly below the coating port 11. The film pressing component 6 is used to press the film 21 tightly against the outer surface of the ultrasonic probe 12. A cutting component 7 is installed on the bottom surface of the inner part of the protective shell 1 at a position close to the film roll 2 of the film pressing component 6. The cutting component 7 is used to cut the film 21 on the transmission component 4. The cutting component 7 is located between the pulling components 5 on both sides. A power supply 13 is also provided inside the protective shell 1. The power supply 13 is used to provide power to the pulling component 5 and the cutting component 7.

[0027] In one embodiment, in combination Figure 2 to Figure 5 The membrane pressing assembly 6 includes a probe tip pressing structure 61 and a probe side pressing structure 62. The probe tip pressing structure 61 is installed on the inner bottom surface of the protective shell 1 and is located directly below the coating opening 11. Four probe side pressing structures 62 are evenly and equidistantly installed around the probe tip pressing structure 61. Each probe side pressing structure 62 is installed on the inner bottom surface of the protective shell 1.

[0028] The probe head end pressing structure 61 includes a fixed cylinder 611, a telescopic rod 612, a head end pressure plate 613 and a return spring 614. The fixed cylinder 611 is vertically fixed on the inner bottom surface of the protective shell 1 at the middle position just below the laminating port 11. The upper end of the fixed cylinder 611 is slidably connected with the telescopic rod 612. The lower end of the telescopic rod 612 is arranged in the fixed cylinder 611. A limiting boss 615 is fixedly arranged at the lower end of the telescopic rod 612, and the upper surface of the limiting boss 615 is in contact with the inner top of the fixed cylinder 611. A return spring 614 is vertically arranged between the lower surface of the limiting boss 615 and the inner bottom of the fixed cylinder 611. The telescopic rod 61 A head end pressing plate 613 is fixedly provided at the upper end, and the upper surface shape of the head end pressing plate 613 is adapted to the shape of the head end of the ultrasonic probe 12, so as to better cover the film 21 on the outer surface of the head end of the ultrasonic probe 12; in a specific implementation, after the ultrasonic probe 12 is inserted from the probe insertion port 10, the outer surface of the head end of the ultrasonic probe 12 presses against the film 21 and presses downward against the head end pressing plate 613, so that the head end pressing plate 613 compresses the return spring 614 through the telescopic rod 612, and then the head end pressing plate 613 elastically presses the film 21 under the reaction force of the return spring 614 to make it fit tightly against the outer surface of the head end of the ultrasonic probe 12.

[0029] The probe peripheral pressing structure 62 includes a fixed bracket 621, a rotating block 622, a sliding rod 623, a pressing head 624 and a pressing spring 625. The fixed bracket 621 is vertically fixed on the inner bottom surface of the protective shell 1 and is located at the outer peripheral side of the coating port 11. A rotating block 622 is rotatably provided on one side of the upper end of the fixed bracket 621 near the head end pressure plate 613. The middle part of the rotating block 622 is laterally slidably connected with the sliding rod 623. A pressing head 624 is fixed at one end of the sliding rod 623 near the head end pressure plate 613. The head shape of the pressing head 624 is semicircular. This arrangement enables the pressing head 624 to better slide in contact with the peripheral outer surface of the ultrasonic probe 12 to prevent the pressing head 624 from damaging the film 21; a pressing spring 625 is sleeved on the sliding rod 623 between the pressing head 624 and the rotating block 622, and an anti-slip baffle 626 is fixed on the other end of the sliding rod 623. A limit plate 62 is fixed on the top of the fixed bracket 621 7. The limit plate 627 is located above the anti-slip baffle 626. The limit plate 627 can limit the upward movement of the anti-slip baffle 626 so that the slide bar 623 remains in a horizontal state. That is, when the ultrasonic probe 12 is inserted, the ultrasonic probe 12 presses the pressing head 624 downward against the film 21, so that the pressing head 624 has a tendency to rotate downward, and the anti-slip baffle 626 at the other end of the slide bar 623 has a tendency to rotate upward. At this time, the anti-slip baffle 626 is limited. The plate 627 blocks the pressing head 624 so that it remains in a horizontal state to facilitate the compression of the film 21 to fit the outer surface of the circumference of the ultrasonic probe 12; in addition, there is no obstruction below the anti-slip baffle 626, that is, when the ultrasonic probe 12 is pulled out, the outer surface of the circumference of the ultrasonic probe 12 drives the pressing head 624 to rotate upward, thereby causing the anti-slip baffle 626 at the other end of the slide bar 623 to rotate downward. At this time, the anti-slip baffle 626 is unobstructed, so that the ultrasonic probe 12 can be pulled out smoothly.

[0030] In addition, the pressing heads 624 in the four probe side pressing structures 62 form a square structure and their size is smaller than the head end size of the ultrasonic probe 12. The head end pressure plate 613 is located below the pressing heads 624. This design makes it easier for the pressing heads 624 and the head end pressure plate 613 to press the film 21 tightly against the outer surface of the ultrasonic probe 12.

[0031] In one embodiment, in combination Figure 2 to Figure 4The conveying assembly 4 includes a guide section roller group 41, a support section roller group 1 42 and a support section roller group 2 43.

This design facilitates the electric clamps 56 to clamp the two sides of the film 21.

[0032] In one embodiment, in combination Figure 2 to Figure 4 The pulling component 5 includes a driving motor 51, a screw rod 52, a threaded block 53, a connecting plate 54, a mounting seat 55 and an electric clamp 56.

A slide groove is provided on the film supporting plane 8 corresponding to the axial position of the screw rod 52. The screw rod 52 is sleeved with a threaded block 53 and the two are threadedly connected. A connecting plate 54 is fixedly provided on the threaded block 53. The connecting plate 54 passes through the slide groove upward and the connecting plate 54 is in sliding contact with the slide groove.

The cutting opening 74 is located between the guide section roller group 41 and the support section roller group 42 in the film conveying channel 9. The length and width of the cutting opening 74 are greater than the length and width of the cutter 73. The length dimension of the cutter 73 is greater than the width dimension of the film 21, so that the cutter 73 can cut the film 21. In addition, a hard plate 75 is fixed at the position corresponding to the cutting opening 74 on the top of the film conveying channel 9. The hard plate 75 is located directly above the cutter 73 to improve the cutting efficiency of the cutter 73.

[0035] Working principle: When in use, the end of the single-layer single-sided low-viscosity film 21 pulled out from the single-sided low-viscosity roll film 2 passes through the guide section roller group 41 in the transmission component 4, so that the two sides of the film 21 are between the jaws of the electric clamp 56, and then the two sides of the film 21 are clamped by the jaws of the electric clamp 56, and then the driving motor 51 in the component 5 drives the screw rod 52 to rotate, so that the thread block 53 moves axially along the screw rod 52, so that the thread block 53 drives the connecting plate 54 to slide along the slide groove, and then drives the electric clamp 56 through the mounting seat 55 to pull the film 21 to move, so that the film 21 passes through the support section roller group 1 42 and the support section roller group 4 in the transmission component 4 in turn. The second group 43 makes the single-sided low-viscosity film 21 at the corresponding positions of the probe insertion port 10 and the film coating port 11, and then the protruding end of the electric push rod 72 in the cutting assembly 7 extends upward to drive the cutter 73 to pass through the cutting port 74 to cut the film 21, and after cutting, the protruding end of the electric push rod 72 retracts downward to drive the cutter 73 back to its original position, and at the same time, the clamping jaws of the electric clamping jaws 56 release the two sides of the film 21, and then the medical staff coats a layer of coupling agent on the outer surface of the cleaned and disinfected ultrasonic probe 12, and then inserts the ultrasonic probe 12 from the probe insertion port 10 and presses against the film 21 downward through the film coating port 11 and then contacts the pressing head 624 in the film pressing assembly 6, and then the ultrasonic probe 12 The surrounding outer surface squeezes the pressing head 624 around to compress the pressing spring 625, and then the pressing head 624 elastically presses the film 21 under the reaction force of the pressing spring 625 so that the film 21 is completely attached to the surrounding outer surface of the ultrasonic probe 12, and the outer surface of the head end of the ultrasonic probe 12 presses against the film 21 and presses downward against the head end pressure plate 613, so that the head end pressure plate 613 compresses the return spring 614 through the telescopic rod 612, and then the head end pressure plate 613 elastically presses the film 21 under the reaction force of the return spring 614 so that it is completely attached to the outer surface of the head end of the ultrasonic probe 12. After the coating is completed, the outer surface of the ultrasonic probe 12 can be wrapped with a layer of film 21, and then the ultrasonic probe 12 can be The head 12 is pulled out and a layer of coupling agent is coated on the outer surface of the film 21, and then the ultrasonic inspection operation can be carried out; then the driving motor 51 in the component 5 is driven in the reverse direction, and then the threaded block 53 is driven by the screw rod 52 to drive the electric clamp 56 to move to the two side edges of the new film 21 at the guide section roller group 41 for subsequent operations; after one inspection is completed, the film 21 is torn off the ultrasonic probe 12 and re-filmed when inspecting a new patient.
