Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drying device and a blood smear preparation device. Background Art

[0002] The blood smear preparation process includes loading a glass slide, printing an information code, applying a sample to the glass slide, drying the glass slide, and staining. Among them, after the sample is applied to the glass slide, the sample is in a wet state and may flow, so it needs to be dried before subsequent processes can be carried out.

[0003] In the prior art, the drying device includes a fan fixed on a bracket, and the air outlet of the fan faces the glass slide. When drying, the fan blows air towards the glass slide.

[0004] However, when the viscosities of the samples on the glass slides are different, the requirements for drying are also different. Since the fan is fixedly arranged, the distance that the air used to dry the sample reaches the glass slide remains fixed, resulting in great difficulty in adjusting the air blowing on the glass slide, affecting the drying effect and reducing the accuracy of subsequent detection results. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a drying device and a blood smear preparation device, which solve the problem that in the prior art, since the distance that the air used to dry the sample generated by the fan reaches the glass slide remains fixed, it is difficult to adjust the air blowing on the glass slide, affecting the drying effect and reducing the accuracy of subsequent detection results.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] In the first aspect, the utility model provides a drying device for drying a glass slide on which a smear has been completed, comprising:

[0008] A fixed bracket;

[0009] A rotating shaft rotatably connected to the fixed bracket;

[0010] A drying component arranged on the rotating shaft and capable of rotating synchronously with the rotation of the rotating shaft to direct the drying air towards the glass slide; and

[0011] A driving mechanism connected to the rotating shaft to drive the rotating shaft to rotate reciprocally to adjust the angle between the drying component and the glass slide.

[0012] Optionally, the drying component includes:

[0013] A drying plate having a plurality of air outlet holes; and

[0014] A blower is provided on the drying plate, and the air outlet of the blower is arranged towards the air outlet hole.

[0015] Optionally, the drying assembly further includes:

[0016] An air regulating plate is detachably connected to the side of the drying plate close to the glass slide. An air regulating hole corresponding to the air outlet hole is formed through the air regulating plate, and the aperture of the air regulating hole is smaller than that of the air outlet hole.

[0017] Optionally, the drying assembly further includes:

[0018] A connecting frame is fixedly connected to the rotating shaft, and the drying plate is slidably connected to the connecting frame in a direction close to or away from the glass slide; and

[0019] A locking member is arranged on the connecting frame and can abut against the drying plate to lock the drying plate.

[0020] Optionally, the drying assembly further includes:

[0021] A heating part is arranged between the drying plate and the blower to heat the air blown out by the blower.

[0022] Optionally, the heating part includes:

[0023] A heating frame is fixed to the drying plate. A heating wire is arranged inside the heating frame. The blower is arranged in the heating frame, and the air outlet of the blower faces the heating wire.

[0024] Optionally, the drying device further includes:

[0025] A temperature detector is arranged on the drying assembly and is used to detect the temperature of the air for drying.

[0026] Optionally, the drying device further includes:

[0027] An angle detector is used to detect the rotation angle of the drying assembly.

[0028] Optionally, the rotation angle range of the drying assembly relative to the glass slide is from 0° to 50°.

[0029] In a second aspect, the present utility model further provides a blood smear preparation device, which includes:

[0030] A smearing device for smearing a glass slide;

[0031] The drying device according to any one of the first aspect, which is used to dry the glass slide after smearing; and

[0032] A staining device for performing staining treatment on the dried glass slide.

[0033] Advantages of the present utility model:

[0034] First, by setting the fixed bracket and the rotating shaft, the rotation axis of the drying component is kept in the same plane as the glass slide. At this time, the rotating shaft is driven to rotate through the driving mechanism to drive the drying component to rotate synchronously, so that the drying component can rotate relative to the glass slide, achieving the effect of adjusting the angle between the drying component and the glass slide. As the angle changes, the distance between the glass slide and the drying component will change to ensure that the strength and temperature of the wind generated by the drying component can both change. Therefore, when using this drying device, according to the different viscosities of the samples, the optimal strength and temperature of the wind during drying can be calculated, and then the angle of the drying component relative to the glass slide can be adjusted through the driving component and the rotating shaft. This can not only ensure that the wind blown by the drying component can contact the sample on the glass slide at the optimal angle, but also ensure that the strength and temperature of the wind can meet the optimal drying requirements, thereby improving the drying rate while ensuring the drying effect and effectively improving the accuracy of subsequent detection.

[0035] Second, when using this blood smear preparation device, samples such as blood can be coated on the surface of the glass slide through the smearing device to form a blood film. Before staining with the staining device, the sample is first dried with the drying device to prevent the sample from flowing during the staining process. During drying, according to the blood viscosity already input into the computer, the strength, temperature, and angle of the wind required for the optimal drying operation can be obtained. Therefore, when using this drying device for drying operations, the angle between the drying component and the glass slide can be adjusted so that the wind blown by the drying component towards the glass slide can meet the requirements, thereby improving the drying efficiency while ensuring the drying quality and effectively improving the accuracy of subsequent detection.

[0046] Embodiment 1

[0047] Refer to Figures 1 to 3, the drying device is used to dry the slide 5 with a smear completed. The drying device includes a fixed bracket 1, a rotating shaft 2, a driving mechanism 3, and a drying component 4. The rotating shaft 2 is rotatably connected to the fixed bracket 1; the driving mechanism 3 is arranged on the fixed bracket 1 and connected to the rotating shaft 2 to drive the rotating shaft 2 to rotate reciprocally; the drying component 4 is arranged on the rotating shaft 2 and can rotate synchronously with the rotation of the rotating shaft 2 to direct the wind for drying to the slide 5; the driving mechanism 3 is connected to the rotating shaft 2 to drive the rotating shaft 2 to rotate reciprocally to adjust the angle between the drying component 4 and the slide 5.

[0048] Specifically, the fixed bracket 1 is U-shaped, and its bottom wall is fixed to the corresponding structure so that the fixed bracket 1 can be located close to the slide 5. At this time, the slide 5 has completed sample coating and is transported to the designated position by the manipulator and waits for drying. The rotating shaft 2 is arranged at the opening of the fixed bracket 1. The two ends of the rotating shaft 2 are respectively rotatably connected to the two side walls of the fixed bracket 1, and one end of the rotating shaft 2 can penetrate through the fixed bracket 1 as a connection end, and the connection end is connected to the driving mechanism 3.

[0049] The driving mechanism 3 includes a driving member 31 and a transmission component 32. The driving member 31 is arranged at the bottom wall of the fixed bracket 1; one end of the transmission component 32 is connected to the output end of the driving member 31, and the other end is connected to the rotating shaft 2. The driving member 31 is a motor, and the transmission component 32 is a belt transmission structure or a gear transmission structure. In this embodiment, the transmission component 32 adopts a belt transmission structure, and the belt is a synchronous belt. In other embodiments, the driving member 31 can also adopt a rotary electric cylinder, etc., and it can also be directly connected to the rotating shaft 2 through a coupling as the transmission component 32. The present invention does not limit the specific composition of the driving mechanism 3, as long as it can satisfy the driving of the rotating shaft 2. It should be understood that the driving mechanism 3 can also be a grasping structure fixed to the connection end of the rotating shaft 2, such as a handle or a crank, etc., so that the user can drive the rotating shaft 2 to rotate by manually applying an external force. On the one hand, it can save energy consumption, and on the other hand, it can also reduce the complexity of the overall structure. The specific composition of the driving mechanism 3 can be designed according to the actual application scenario.

[0050] The drying component 4 is fixed on the rotating shaft 2 to rotate synchronously with the rotation of the rotating shaft 2. The drying component 4 is located above the rotating shaft 2. The rotating shaft 2 and the slide 5 can be in the same horizontal plane, so that the rotation axis of the drying component 4 and the slide 5 are in the same horizontal plane to facilitate controlling the angle between the drying component 4 and the slide 5. The drying component 4 can internally install a blower 42 to generate wind blowing towards the slide 5, or it can be a wind guiding structure and be configured with an air duct connected to an external blower 42 to direct the wind to the slide 5. The wind can be in a normal temperature state, or in a temperature-adjusted high temperature state or low temperature state.

[0051] By setting the fixed bracket 1 and the rotating shaft 2, the rotation axis of the drying component 4 is kept in the same plane as the glass slide 5. At this time, the driving mechanism 3 is used to drive the rotation of the rotating shaft 2 to drive the drying component 4 to rotate synchronously, so that the drying component 4 can rotate relative to the glass slide 5, achieving the effect of adjusting the angle between the drying component 4 and the glass slide 5. As the angle changes, the distance between the glass slide 5 and the drying component 4 will change to ensure that the strength and temperature of the wind generated by the drying component 4 can both change. In this way, when the drying device is in use, according to the different viscosities of the samples, the optimal strength and temperature of the wind during drying can be calculated, and then the angle of the drying component 4 relative to the glass slide 5 can be adjusted through the driving component and the rotating shaft 2. This can not only ensure that the wind blown by the drying component 4 can contact the sample on the glass slide 5 at the optimal angle, but also ensure that the strength and temperature of the wind can meet the optimal drying requirements, thereby improving the drying rate while ensuring the drying effect and effectively improving the accuracy of subsequent detection.

[0052] Optionally, the drying component 4 includes a drying plate 41 and a blower 42. The drying plate 41 has a plurality of air outlet holes 411. The blower 42 is arranged on the drying plate 41 and the air outlet of the blower 42 is arranged facing the air outlet holes 411.

[0053] Specifically, the drying plate 41 is rectangular in shape, is connected to the rotating shaft 2 and can rotate synchronously with the rotating shaft 2. One side of the drying plate 41 faces the glass slide 5, and the blower 42 is fixedly arranged on the other side. A plurality of air outlet holes 411 are respectively arranged on the drying plate 41. The plurality of air outlet holes 411 can be arranged in an array on the drying plate 41, can be randomly distributed on the drying plate 41, or can be distributed in a certain shape such as a ring on the drying plate 41. The aperture of the air outlet holes 411 is relatively small, which can be 1 mm or several millimeters, and can be specifically set according to the size of the drying plate 41 and the number of the air outlet holes 411. The plurality of air outlet holes 411 are all located at the middle position of the drying plate 41, and the blower 42 is also fixed at the middle position of the drying plate 41 to ensure that the blower 42 can be in correspondence with the air outlet. The blower 42 can adopt a variable-frequency blower 42 to flexibly adjust the power of the blower 42, so as to achieve the effect of flexibly adjusting the wind speed.

[0054] By setting the drying plate 41 and the blower 42, the blower 42 generates wind during drying, and the wind is blown out through the plurality of air outlet holes 411. The plurality of air outlet holes 411 can disperse the wind and blow it towards the glass slide 5 to ensure that the wind can fully contact the sample on the glass slide 5, thereby effectively improving the drying effect on the sample and ensuring that the drying effects of the samples at various parts on the glass slide 5 are consistent.

[0055] Optionally, the drying component 4 further includes an air regulating plate (not shown in the figure). The air regulating plate is detachably connected to the side of the drying plate 41 close to the glass slide 5. The air regulating plate is provided with air regulating holes corresponding to the air outlet holes 411 in a penetrating manner, and the aperture of the air regulating holes is smaller than that of the air outlet holes 411.

[0056] Specifically, the air regulating plate is arranged on the side surface of the drying plate 41. The connection mode between the air regulating plate and the drying plate 41 can be a detachable connection mode such as plugging or clamping. For example, a T-shaped clamping block is respectively arranged on both sides of the air regulating plate, and a T-shaped sliding groove for the clamping block to slide is arranged on the regulating plate. The specific connection mode between the two can be selected according to the actual installation difficulty, and the present utility model does not make a limitation. A plurality of air regulating holes are provided in the air regulating plate in a penetrating manner. After the air regulating plate is installed on the drying plate 41, the air regulating holes can be in one-to-one correspondence and communication with the air outlet holes 411, and the aperture of the air regulating holes is smaller than that of the air outlet holes 411. A plurality of air regulating plates can be prepared, and the apertures of the air regulating holes on different air regulating plates are different. The air regulating holes can also be arranged as tapered holes or the like to achieve the purpose of reducing the aperture of the air regulating holes.

[0057] By preparing the air regulating plate, different air regulating plates with different apertures can be selected according to different samples and installed on the drying plate 41 to change the aperture size of the holes through which the wind blows out. The air regulating holes with a small aperture can increase the wind speed, so that the wind can quickly blow towards the glass slide 5, thereby improving the drying efficiency of the corresponding sample. At the same time, the drying device can also dry more types of samples, effectively improving the adaptability of the drying device.

[0058] Optionally, the drying component 4 further includes a heating part. The heating part is arranged between the drying plate 41 and the blower 42 to heat the wind blown out by the blower 42.

[0059] Specifically, the heating part is arranged on the side of the drying plate 41 close to the blower 42. The blower 42 is fixed on the side of the heating part away from the drying plate 41. The heating part can be in a plate shape and can generate heat by itself. Through holes corresponding to the air outlet are provided on the heating part. When the air outlet of the blower 42 generates wind, the wind will pass through the through holes of the heating part and absorb heat to raise the temperature of the wind to the optimal drying temperature. The heating part can also be formed in a frame-shaped structure with heating wires arranged inside.

[0060] By arranging the heating part, the wind generated by the blower 42 can be heated so that the temperature of the wind blowing towards the glass slide 5 is higher than the normal temperature or room temperature, thereby further improving the drying effect on the sample.

[0061] Optionally, the heating part includes a heating frame 43. The heating frame 43 is fixed to the drying plate 41. The heating frame 43 is provided with heating wires inside, and the blower 42 is arranged in the heating frame 43, and the air outlet of the blower 42 faces the heating wires.

[0062] Specifically, the heating frame 43 is fixed to the drying plate 41, and the fixing method can be welding, bonding, or bolt connection. The housing of the fan is fixed to the heating frame 43. A plurality of heating wires are distributed at intervals within the heating frame 43. The heat generated by the heating wires forms a heating space within the heating frame 43. When the air generated by the blower 42 passes through the heating frame 43, the air can smoothly absorb heat and be heated to the specified temperature. Moreover, through the cooperation of the heating frame 43 and the heating wires, a sufficiently large cavity is formed within the heating frame 43 to ensure that the air generated by the blower 42 can smoothly blow towards the air outlet 411, reducing the possibility of the heating part interfering with the flow of air.

[0063] Optionally, the drying device further includes a temperature detector 6 and an angle detector 7. The temperature detector 6 is disposed on the drying assembly 4 and is used to detect the temperature of the air for drying. The angle detector 7 is used to detect the rotation angle of the drying assembly 4.

[0064] Specifically, the temperature detector 6 can be disposed on the drying plate 41, mainly for detecting the temperature of the air passing through the air outlet 411. According to the temperature detection data, the power of the heating part can be adjusted, and the position of the drying assembly 4 relative to the glass slide 5 can also be adjusted to precisely control the temperature of the air blown onto the glass slide 5. The angle detector 7 can detect the rotation angle of the rotating shaft 2 in real time, thereby determining the rotation angle of the drying assembly 4. The angle detector 7 can also only detect the maximum rotation angle of the rotating shaft 2 to prevent the rotation amplitude of the drying assembly 4 from exceeding the limit value. In this embodiment, the angle detector 7 uses an optocoupler sensor. The optocoupler sensor is fixed above the motor, and an induction part is provided on the rotating shaft 2. The induction part can correspond to the optocoupler sensor at the maximum rotation angle of the rotating shaft 2 to trigger the optocoupler sensor.

[0065] Optionally, the range of the rotation angle α of the drying assembly 4 relative to the glass slide 5 is from 0° to 50°.

[0066] Specifically, 0° means that the drying plate 41 of the drying assembly 4 is parallel to the glass slide 5. At this time, the air from the blower 42 of the drying assembly 4 blows vertically towards the glass slide 5, and 50° means that the included angle between the drying plate 41 of the drying assembly 4 and the support of the glass slide 5 is 50°. At this time, the air blown out by the blower 42 blows towards the glass slide 5 at an included angle of 40°. It should be understood that in other embodiments, the rotation angle of the drying assembly 4 can also be other angle ranges, rather than being limited to the 0° to 50° in the above example. Specifically, it can be selected according to the characteristics of the actual sample.

[0067] The blood smear preparation device includes a smearing device, a staining device, and a drying device as described in the above embodiments. The smearing device is used to smear the glass slide 5; the drying device is used to dry the glass slide 5 after smearing; the staining device is used to perform a staining treatment on the glass slide 5 after drying.

[0068] When in use, the blood smear preparation device can coat samples such as blood on the surface of the glass slide 5 through a smearing device to form a blood film. Before staining with the staining device, the sample is first dried with the drying device to avoid sample flow during the staining process. During drying, according to the blood viscosity already input into the computer, the intensity, temperature, and angle of the wind required for the optimal drying operation can be obtained. Thus, when using the drying device for the drying operation, the angle between the drying component 4 and the glass slide 5 can be adjusted so that the wind blowing towards the glass slide 5 generated by the drying component 4 can meet the requirements, thereby improving the drying efficiency while ensuring the drying quality and effectively improving the accuracy of subsequent detection.

[0069] Embodiment 2

[0070] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 lies in the different connection methods between the drying component 4 and the rotating shaft 2.

[0071] Optionally, the drying component 4 further includes a connecting frame (not shown in the figure) and a locking member (not shown in the figure). The connecting frame is fixedly connected to the rotating shaft 2, and the drying plate 41 is slidably connected to the connecting frame in a direction close to or away from the glass slide 5; the locking member is arranged on the connecting frame and can abut against the drying plate 41 to lock the drying plate 41.

[0072] Specifically, the connecting frame can also be U-shaped. Its bottom wall is fixedly connected to the rotating shaft 2, and its side walls extend radially along the rotating shaft 2 and form a sliding connection with the drying plate 41. A locking member is inserted through the side wall of the connecting frame. The locking member can be a locking bolt, which is inserted through the side wall of the connecting frame, and the end of the locking bolt can abut against the side wall of the drying plate 41 to lock the position of the drying plate 41. The locking member can also be a plug rod. A plurality of insertion holes for the plug rod to be inserted can be spacedly arranged on the side wall of the drying plate 41. Through the cooperation of the plug rod and the insertion holes, the locking of the drying plate 41 can also be achieved. The specific locking member can be designed according to the actual installation difficulty, and the present utility model does not limit this.

[0073] By providing the connecting frame and the locking member, the distance between the drying component 4 and the glass slide 5 can be adjusted by driving the drying component 4 to slide relative to the connecting frame, thereby further adjusting the intensity and temperature of the wind blown onto the glass slide 5, improving the flexibility of adjustment. Moreover, after the adjustment is completed, the position of the drying plate 41 can be quickly locked by the locking member. At the same time, during the distance adjustment process, the rotation axis of the drying plate 41 is still the axis of the rotating shaft 2, so that the adjustment of the distance does not increase the control difficulty of the included angle size, facilitating precise angle adjustment after the distance adjustment is completed.

[0074] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
