Description

Technical Field

[0001] The utility model relates to the technical field of medical sanitary equipment, in particular to a sterile bed sheet replacement device suitable for an ultrasonic examination bed. Background Art

[0002] When diagnosing patients in the ultrasound department, the examinee needs to lie down so that the intercostal space can be repeatedly opened to obtain a more accurate image. Therefore, an ultrasound examination bed is indispensable for echocardiography. However, the patient needs to lie on the examination bed and then expose the part of the body to be examined. This inevitably causes the skin of the person to be examined to come into direct contact with the examination bed. In order to keep it clean and prevent cross-infection between patients, medical staff need to frequently change the bed sheets, which also need to be disinfected and cleaned later, which is time-consuming and labor-intensive, and also affects the normal work efficiency of medical staff.

[0003] Therefore, there are devices that can automatically replace sterile sheets in use. For example, a Chinese patent document discloses a disposable sheet for ultrasonic examination and an examination bed using the sheet. The patent document number is CN21667577U. The examination bed is equipped with an electric roller machine at the foot of the bed and a bracket at the head of the bed. A roll of paper sheets is rotatably connected between the electric roller machine and the bracket. The electric roller machine drives the sheet to be wound for updating.

[0004] However, the above-mentioned device is not convenient to be installed on the existing ordinary examination bed. At the same time, when conducting an examination, the person to be examined needs to first sit on the examination bed, and then turn to an examination position that is roughly parallel to the examination bed. At this time, the body pressure and movement of the examiner will cause wrinkles on the sheets on the examination bed. The wrinkles will make the sheets not flat enough and difficult to fully unfold or align correctly, including affecting the subsequent automatic updating of the sheets or affecting the user experience when subsequent persons to be examined are examined. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a sterile bed sheet replacement device suitable for an ultrasonic examination bed, which can solve the problem of replacing the sterile bed sheet of the examination bed and the replaced sterile bed sheet can be laid flat on the examination bed.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a sterile sheet replacement device suitable for an ultrasonic examination bed, comprising a bed body, a unwinding mechanism and a rewinding mechanism, characterized in that the unwinding mechanism and the rewinding mechanism are respectively arranged on both sides of the bed body along the length direction of the bed body; the unwinding mechanism comprises a shell fixed to the head of the bed and a sterile sheet roll rotatably arranged in the shell, and the shell is located above the sterile sheet roll and is also provided with a tensioning mechanism; the rewinding mechanism comprises a motor mounting box and a mounting plate, an axis roller and a paper roll relatively fixed on both sides of the foot of the bed, the axis roller and the paper roll are rotatably arranged between the motor mounting box and the mounting plate from top to bottom, the axis roller is symmetrically provided with spiral grooves along the axial direction, and the sterile sheet on the sterile sheet roll extends out of the shell and passes through the tensioning mechanism and the axis roller in sequence and then connects to the paper roll.

[0007] Furthermore, a tensioning mechanism is also provided on the shell, and the tensioning mechanism includes a tensioning shaft and a pressing assembly arranged above the sterile bed sheet cylinder, and the sterile bed sheet on the sterile bed sheet roll passes between the tensioning shaft and the pressing assembly.

[0008] Furthermore, a fixing rod is installed on the shell, and the clamping assembly is installed on the fixing rod. The clamping assembly includes a mounting seat, a mounting rod, a spring and an arc-shaped pressure block. One end of the mounting rod is inserted into the mounting seat, and the other end is fixedly connected to the arc-shaped pressure block. The spring is sleeved on the mounting rod and is located between the mounting seat and the arc-shaped pressure block. The arc-shaped pressure block is rotatably provided with rollers at both ends along the arc-shaped surface, and the rollers are in elastic contact with the tensioning shaft through the spring.

[0009] Furthermore, at least two pressing groups are arranged on the fixing rod.

[0010] Furthermore, the top of the mounting rod extends out of the fixing rod and is connected with a pull button.

[0011] Furthermore, a guide groove is vertically provided on the upper side of the shell, the fixing rod is slidably installed in the guide groove, and a locking knob is connected to one side of the fixing rod.

[0012] Furthermore, the upper side of the mounting plate is fixed on the bed body, the lower side of the mounting plate is rotatably connected to a movable plate, the two ends of the paper tube are respectively detachably clamped on the motor mounting box and the movable plate, a movable rod is rotatably mounted on one side of the mounting plate, a buckle is fixed to the tail end of the movable rod, and a slot cooperating with the buckle is provided on the movable plate.

[0013] Furthermore, the shaft roller rotates counterclockwise, and the paper tube rotates counterclockwise or clockwise.

[0014] In summary, the utility model has the following beneficial effects:

[0015] (1) Through the arrangement of the unwinding mechanism and the rewinding mechanism, sterile sheets, sterile cloths, etc. can be laid out in the length direction of the examination bed as the sheets of the examination bed to ensure cleanliness and hygiene, and the sterile sheets can be smoothly conveyed and rewound, thereby achieving the purpose of updating the examination area. The unwinding mechanism presses the sterile sheets on the tensioning shaft through the pressing component, which can prevent the sterile sheets from generating strip-shaped wrinkles in the width direction. At the same time, when the inspectors use it, it can avoid the misalignment of a large number of wrinkles caused by use, which affects the continued use or the updating of the inspection area by unwinding and replacing the sterile sheets.

[0016] (2) When the paper roller drives the sterile sheet to be rolled up and the detection area is updated, the wrinkles caused by the previous user are flattened in the horizontal direction by the rotation guide of the spiral groove on the shaft roller, thereby eliminating the wrinkles on the sterile sheet and making it easier for the paper roller to neatly roll up the sterile sheet after use.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] like Figure 1 to Figure 2 As shown, a sterile bed sheet replacement device suitable for an ultrasonic examination bed comprises a bed body 1, a reeling mechanism 2, a reeling mechanism 3 and a motor mounting box 31 provided with a driving motor, wherein the reeling mechanism 2 and the reeling mechanism 3 are respectively arranged on both sides of the bed body 1 along the length direction of the bed body 1; the reeling mechanism 2 comprises a shell 21 fixed to the head of the bed and a sterile bed sheet roll rotatably arranged in the shell 21, and the shell 21 is located above the sterile bed sheet roll and is also provided with a tensioning mechanism 5; the reeling mechanism 3 comprises a motor mounting box 31 and a mounting plate 32, an axis roller 33 and a paper roll 34 relatively fixed on both sides of the foot of the bed, the axis roller 33 and the paper roll 34 are rotatably arranged between the motor mounting box 31 and the mounting plate 32 from top to bottom, the axis roller 33 is symmetrically provided with a spiral groove 331 along the axial direction, and the sterile bed sheet on the sterile bed sheet roll extends out of the shell 21 and passes through the tensioning mechanism 5 and the axis roller 33 in sequence and then connects to the paper roll 34.

[0027] By setting up the unwinding mechanism 2 and the rewinding mechanism 3, the smooth transmission and rewinding of the sterile bed sheet is realized, ensuring the renewal of the sterile bed sheet on the ultrasound examination bed. When in use, a new sterile bed sheet roll is installed at the head of the bed, and the sterile bed sheet is pulled out from the shell 21 and successively wrapped around the clamping component 52 and the shaft roller 33, and then connected to the paper roll 34 by glue. The paper roll 34 is rotated and rerolled under the drive of the motor, thereby completing the renewal of the sterile bed sheet. After unwinding, the paper roll 34 can be installed at the end of the bed for recycling the sterile bed sheet.

[0028] In implementation, the housing 21 is further provided with a tensioning mechanism 5, which includes a tensioning shaft 51 and a pressing assembly 52 arranged above the sterile bed sheet roll, and the sterile bed sheet on the sterile bed sheet roll passes between the tensioning shaft 51 and the pressing assembly 52. ​​The tensioning shaft 51 can be set in a rotating and fixed manner.

[0029] The tensioning mechanism 5 maintains the appropriate tension of the sterile bed sheet to ensure that it will not sag or loosen during the transmission process. The sterile bed sheet passing point between the tensioning shaft 51 and the pressing assembly 52 provides appropriate tension to prevent the sterile bed sheet from sag or wrinkles. This ensures the stable transmission and quality of the sterile bed sheet.

[0030] Embodiment 2:

[0031] like Figures 1 to 4 As shown, a sterile bed sheet replacement device suitable for an ultrasonic examination bed in Example 1 includes a bed body 1, an unwinding mechanism 2, a rewinding mechanism 3, and a motor installation box 31 provided with a driving motor. The tensioning mechanism 5 includes a tensioning shaft 51 and a pressing assembly 52 provided above the sterile bed sheet drum. The sterile bed sheet on the sterile bed sheet drum passes between the tensioning shaft 51 and the pressing assembly 52. ​​The pressing assembly 52 applies pressure to the outer periphery of the tensioning shaft 51 to press the sterile bed sheet bypassing the tensioning shaft 51 to avoid excessive deviation or wrinkles. The tensioning mechanism 5 can maintain the appropriate tension of the sterile bed sheet, ensure that it will not be slack or loose during the transmission process, and ensure the stable transmission of the sterile bed sheet.

[0032] The shell 21, the mounting plate 32 and the motor mounting box 31 can fix the winding mechanism 3 and the unwinding mechanism 2 on the examination bed, and are suitable for general examination beds, including installation on existing examination beds without a sheet replacement device, and are installed on the edge crossbeams or longitudinal beams of the bed body with screws or bolts.

The spring is sleeved on the mounting rod 522 and located between the mounting seat 521 and the arc-shaped pressing block 523. The arc-shaped pressing block 523 is rotatably provided with rollers 524 at both ends along the arc surface. The rollers 524 are in elastic contact with the tensioning shaft 51 through the spring. A limiting disk is coaxially provided on the mounting rod 522, and the spring is located between the limiting disk and the arc-shaped pressing block 523. The mounting rod 522 passes through the hole on the mounting seat 521 and is connected to the pull button 525. This clamping assembly 52 ensures that the correct position and tightness are maintained during the winding process. The combination of the mounting seat 521 , the mounting rod 522 and the spring provides an adjustable mechanism. By adjusting the pressure of the spring, the degree of compression of the roller 524 on the tensioning shaft 51 can be controlled.

[0034] During implementation, at least two clamping assemblies 52 are provided on the fixed rod 6. By providing at least two clamping assemblies 52 on the fixed rod 6, more support and stability are provided, and the two clamping assemblies 52 are provided on both sides of the fixed rod 6 in the axial direction, and the positions of the two clamping assemblies 52 are respectively provided between the end and the middle position of the fixed rod 6, so that the deviation or instability during the winding can be avoided, and the smooth winding of the sterile bed sheet can be ensured.

[0035] Preferably, the top of the mounting rod 522 extends out of the fixing rod 6 and is connected with a pull button 525. The pull button 525 at the top of the mounting rod 522 provides convenient operation and adjustment, and the operator can adjust the position of the sterile sheet or arrange the wrinkles by pulling the pull button 525.

[0036] During implementation, a guide groove 211 is vertically provided on the upper side of the housing 21, and the fixing rod 6 is slidably installed in the guide groove 211.
