Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic examination auxiliary equipment, and in particular to protective equipment for ultrasonic examination of a patient's private parts. Background Art

[0002] When an ultrasound doctor examines a patient, he first needs to expose part of the patient's body, then slide the probe over the patient's body to project the image. During the examination, some private parts are sometimes involved, but in order to check the condition, the patient has to follow the doctor's instructions, especially for doctors of the opposite sex and patients, which is inevitably awkward. Moreover, for nervous patients, when facing the doctor directly, they will feel timid or even panic.

[0003] The patent document with patent number CN202120184048.8 discloses a privacy shielding mechanism for ultrasound doctors, including a guide plate, wherein the upper surface of the guide plate is provided with a guide groove along the length direction, and a shielding plate is slidably connected in the guide groove, and the shielding plate is pushed along the guide groove, and a first locking member is provided on the outer side of each end of the guide groove, and the first locking member is used to limit the position of the guide plate in the guide groove, and a first rotating part is provided on both sides of the lower end of the guide plate, and a swing plate is rotatably connected to the first rotating part. During the examination, the doctor's arm extends from one side of the shielding plate to the patient's examination area without interference. At the same time, the lying patient is in a lower position, and the shielding plate can play a certain shielding role, and embarrassment can be avoided as much as possible when examining the private parts. Moreover, the lying patient has a lower line of sight, which can avoid eye contact with the doctor's line of sight, thereby reducing the tension of some patients.

[0004] Although this solution can form a shielding effect between the doctor and the patient through the shielding plate, during the examination process, due to the obstruction of the shielding plate, the doctor's hand will need to go around the shielding plate from the side, which is inconvenient for the doctor to operate the ultrasound probe and hinders the doctor's operation; and although this solution can block the patient's line of sight, it also blocks the doctor's line of sight, making it impossible for the doctor to judge the position of the detection instrument on the patient's body in the obstructed state.

The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0034] See also Figure 1-9 The present invention provides a technical solution: a protective device for ultrasonic examination of a patient's private parts, comprising two shielding curtains 1 and a sleeve for fixing an ultrasonic probe, the two shielding curtains 1 are each provided with a winding mechanism on one side opposite to the other, and a guide rod 2 is provided on the opposite side, the sleeve comprises two mutually buckled clamping parts 3, the two clamping parts 3 are each provided with a card groove on the opposite side, and are respectively slidably matched with the two guide rods 2, and the tops of the two clamping parts 3 are each provided with a fixing block.

[0035] The rolling mechanism is used for storing the shielding curtain 1. The shielding curtain 1 can be pulled out of the rolling mechanism by pulling the side of the shielding curtain 1. The side is provided with a guide rod 2 as a traction part. The shielding curtain 1 can be pulled out of the rolling mechanism by pulling the guide rod 2. When the pulling force on the guide rod 2 is cancelled, the rolling mechanism rolls up the shielding curtain 1 so that the shielding curtain 1 is retracted into the rolling mechanism; the application is used to fix the ultrasonic probe, which is composed of two clamping parts 3. The two clamping parts 3 have card grooves on opposite sides. The two card grooves form a space for installing and placing the ultrasonic probe after the two clamping parts 3 are spliced ​​together. The fixing blocks arranged at the upper ends of the two clamping parts 3 can be fixed by binding after the two clamping parts 3 are spliced ​​together to maintain the spliced ​​state of the two clamping parts 3. The two clamping parts 3 are slidably matched with the two guide rods 2 respectively, so that the sleeve can slide along the guide rods 2 with the two guide rods 2 as tracks;

[0036] The specific method of use is to first install the two rolling mechanisms on both sides of the examination bed, and the patient lies flat on the examination bed, and then pull the guide rod 2 to pull the two shielding curtains 1 inward, and then place the ultrasound probe between the two clamping parts 3, and then fix the ultrasound probe by binding the two fixing blocks, so as to fix the two guide rods 2, so that the two shielding curtains 1 are in a straight state under the reverse pulling of the rolling mechanism; when moving the ultrasound probe, the extension direction of the guide rod 2 is the X-axis direction, and the direction of the two rolling mechanisms is the Y-direction. When the ultrasound probe needs to be moved along the X-axis direction, it is moved along the guide rod 2. Rod 2 slides, and when the ultrasound probe needs to move along the Y-axis direction, one of the shielding curtains 1 will be dragged by the guide rod 2 to extend from the reeling mechanism, and the other shielding curtain 1 will be reeled in under the action of the corresponding reeling mechanism. When the ultrasound probe is moved, the two shielding curtains 1 always remain in a spliced ​​state to shield the patient, and will not form an obstacle between the ultrasound probe and the doctor, and will not hinder the detection. At the same time, the patient platform is covered by the shielding curtain 1, and the doctor can make a preliminary judgment on the specific position of the ultrasound probe on the patient according to the patient's lying posture.

[0037] In this embodiment, a mounting plate 314 is provided on the top of each of the two clamping parts 3 , and a mounting hole 5 for the guide rod 2 to pass through and an opening 6 for the shielding curtain 1 to pass through are opened on the mounting plate 314 .

[0038] The mounting plate 314 is provided with a mounting hole 5 and an opening 6, and the opening 6 is connected to the mounting hole 5 and is in an open state. During installation, the mounting block is installed by one end of the guide rod 2, and the end of the guide rod 2 is inserted into the mounting hole 5. The side of the shielding curtain 1 is inserted into the opening 6, so that the mounting plate 314 can be slidably matched with the guide rod 2, so as to realize the two clamping parts 3 to be slidably matched with the two guide rods 2 respectively, and finally realize that the ultrasonic probe installed in the sleeve can slide on the two guide rods 2.

[0039] In this embodiment, the two opposite sides of the blackout curtains 1 are sewn together to form a tubular structure wrapped around the guide rod 2, and a protective shell 7 is provided outside the tubular structure.

[0040] After the side of the shielding curtain 1 is curled, it is sewn or pasted to form a tubular structure, and the guide rod 2 passes through the tubular structure to connect the shielding curtain 1 with the guide rod 2, and a protective shell 7 is set on the outside. The protective shell 7 will wrap the outside of the shielding curtain 1 to form a protective structure between the shielding curtain 1 and the mounting plate 314, so that the mounting plate 314 will not directly contact the shielding curtain 1 during the sliding process, thereby protecting the shielding curtain 1.

[0041] In this embodiment, a connecting buckle 8 is provided between the two ends of the two guide rods 2, a ring 9 is provided at one end of the connecting buckle 8, and a hook 10 is provided at the other end. The ring 9 is sleeved on the end of one guide rod 2, and the hook 10 is hooked on the end of the other guide rod 2.

[0042] The connecting buckle 8 is used to connect one end of the same side of the two guide rods 2, and a ring 9 and a hook 10 are respectively provided at both ends thereof. The connecting buckle 8 is rotatably connected to the end of one of the guide rods 2 through the ring 9, and is clamped with the end of the other guide rod 2 through the hook 10. By respectively providing the hooks 10 at both ends of the two guide rods 2, the connection between the two ends of the two guide rods 2 is realized, and the hooks 10 can facilitate assembly and disassembly operations.

[0043] In this embodiment, a through slot 11 extending along the length direction is formed on opposite sides of the two fixing blocks.

[0044] A through slot 11 is formed on one side opposite to the two fixing blocks, and the two through slots 11 are buckled together to form a channel for a signal conducting connection line such as a wire or a catheter connected to the ultrasound probe.

[0045] In this embodiment, an operating handle 12 is also included. The operating handle 12 is a tubular structure with a hollow side wall. The operating handle 12 is sleeved outside the two fixed blocks. A first through hole 13 and a second through hole 14 are provided on the side wall of the operating handle 12. The first through hole 13 and the second through hole 14 are both connected to the inside of the operating handle 12. A first one-way valve 17 is provided in the first through hole 13, and the first one-way valve 17 opens to the inside of the operating handle 12. A second one-way valve 18 is provided in the second through hole 14, and the second one-way valve 18 opens to the outside of the operating handle 12. The two clamping parts 3 are both hollow structures. A third through hole 15 is provided on the top of the two clamping parts 3. The third through hole 15 is connected to the second through hole 14 through a pipeline, and a fourth through hole 16 for filling or discharging gel is provided on the bottom surface.

[0046] The operating handle 12 is sleeved outside the two fixing blocks to fix the two fixing blocks so that the two clamping parts 3 remain in a buckled state. The operating handle 12 can be made of elastic materials such as rubber, and can be pressed to shrink the operating handle 12. After the pressing is canceled, the operating handle 12 can be reset by its own elasticity. The operating handle 12 is provided with a first through hole 13 and a second through hole 14, and a first one-way valve 17 and a second one-way valve 18 are respectively arranged in the first through hole 13 and the second through hole 14. When the operating handle 12 is pressed, the first one-way valve 17 remains in a closed state, and the air in the operating handle 12 is discharged outwardly by the second one-way valve 18. When the operating handle 12 is reset, the second one-way valve 18 remains in a closed state, and the outside air enters the operating handle 12 through the first one-way valve 17.

[0047] The two clamping parts 3 are both hollow structures, with a third through hole 15 on the top and connected to the second through hole 14 through a pipe, and a fourth through hole 16 on the bottom. The gel to be applied during the inspection can be pre-injected into the two clamping parts 3 through the fourth through hole 16. During the inspection, by squeezing the operating handle 12, air can be pumped from the second through hole 14 through the pipe into the third through hole 15, and then the air is injected into the two clamping parts 3, so that the gel pre-injected into the two clamping parts 3 is pressed out from the fourth through hole 16 and applied to the patient's skin. The gel can be pre-stored and discharged as needed, and there is no need to cancel the shielding state of the shielding curtain 1 on the patient when applying the gel;

[0048] In addition, a sealing strip 19 is provided on the bottom surface of the two clamping parts 3, and a connecting rod 20 extending into the fourth through hole 16 is provided on the sealing strip 19, a limit block 21 is provided at the end of the connecting rod 20, and a support spring 22 is sleeved on the connecting rod 20, and both ends of the support spring 22 abut between the bottom surface of the clamping part 3 and the limit block 21, so that the sealing strip 19 maintains a sealed state with the two clamping parts 3, realizes unidirectional conduction of the fourth through hole 16, and avoids contamination of the gel stored inside.

[0049] In this embodiment, the winding mechanism includes a shell 23 and a rotating shaft 24 arranged in the shell 23. A fixing groove is opened on the side of the rotating shaft 24. The side edge of the shielding curtain 1 extends into the shell 23 and is fixed in the fixing groove. End covers 25 are arranged at both ends of the shell 23. The two ends of the rotating shaft 24 extend outward through the two end covers 25 respectively and are rotatably connected to the end covers 25.

The outward end of the coil spring 27 is connected to the side wall of the end cover 25, and the inward end is connected to the side wall of the rotating shaft 24.

[0050] The shell 23 is used to accommodate the rotating shaft 24 and the black curtain 1 rolled up on the rotating shaft 24. End covers 25 are set at both ends of the shell 23, and the two end covers 25 serve as supports for the two ends of the rotating shaft 24 respectively. A mounting groove 26 for installing a coil spring 27 is set on the outward side of the end cover 25. The two ends of the coil spring 27 are respectively connected to the side walls of the mounting groove 26 and the side walls of the rotating shaft 24, forming a reset structure between the rotating shaft 24 and the mounting groove 26. When the black curtain 1 is stretched outward, the rotating shaft 24 will be driven to rotate, thereby causing the coil spring 27 to deform. After the pulling force on the black curtain 1 is cancelled, the rotating shaft 24 is driven to rotate in the opposite direction through the elastic reset of the coil spring 27, so that the black curtain 1 is received in the shell 23.
