[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] The embodiment of the present application provides a multi-channel laminar flow bed, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0034] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] Example 1

[0036] See also Figure 1-11 In the embodiment, a multi-channel laminar flow bed is provided, which is characterized in that it includes: a bed body 1, a lower box body 2 is provided on the top of the bed body 1, and a plurality of support rods 101 are connected to the bottom of the box body 2, and a connecting rod 102 is connected between the two support rods 101 on the same side, and a soft channel 4, a hard channel 401 and a logistics channel 402 are provided on the connecting rod 102 in sequence; a masking component arranged at the bottom of the box body 2 is used to protect the privacy of the patient, and the masking component includes: a first slide 8, a flexible transparent screen 801, a second slide 802 and a masking screen 803; a disinfection component arranged between the soft channel 4, the hard channel 401 and the logistics channel 402 and the box body 2, and is used to disinfect the inside of the soft channel 4, the hard channel 401 and the logistics channel 402, and the disinfection component includes: a disinfection chamber 3, a guide tube 302, a disinfection tube 5, an atomizing nozzle 501, a sealing plate 601 and an ejection plate 702.

[0037] By adding the soft channel 4, the hard channel 401 and the logistics channel 402, the opening and closing of the flexible transparent screen 801 can be minimized, the internal environment of the laminar flow bed can be maintained, unnecessary infection can be reduced, and it is convenient for patients to perform blood drawing, infusion, blood pressure measurement, lumbar puncture and other operations, while facilitating the entry and exit of objects. Secondly, with the setting of the disinfection component, the channel can be closed and disinfected after opening to prevent residual bacteria from entering the laminar flow bed when the channel is open. Then, through the setting of the masking component, the environment inside the laminar flow bed can be masked, effectively protecting the patient's privacy and increasing the patient's comfort.

[0038] Example 2

[0039] On the basis of Example 1, an equipment cavity 201 is opened inside the box body 2, a purification and filtering equipment body 202 is installed inside the equipment cavity 201, a silent fan 205 is installed inside the equipment cavity 201, a plurality of air inlet pipes 203 are opened on one side of the box body 2, a plurality of air outlet holes 204 are opened in the middle of the bottom surface of the box body 2, and the air outlet holes 204 are communicated with the equipment cavity 201.

[0040] After CART treatment is carried out in the neurology department, the patient will experience a period of decreased immunity. Especially for extremely immunosuppressed patients, strict isolation measures need to be taken to limit visitor contact, ensure a clean and sterile environment, and reduce exposure to external pathogens. However, the existing laminar flow beds are difficult to meet the needs of neurology patients. When patients are infusing or collecting blood samples, they need to open the flexible transparent screen 801 on the laminar flow bed, which destroys the sterile environment inside the laminar flow bed and increases the risk of infection for patients. At this time, the soft channel 4, the hard channel 401 and the logistics channel 402 can be set to reduce the opening of the flexible transparent screen 801.

[0041] After the patient moves into the bed 1, the flexible transparent screen 801 is pulled up around the bed 1 to isolate the bed 1 from the outside world. Then, the silent fan 205 operates to allow the outside air to enter the device cavity 201 through the air inlet pipe 203, and the purification and filtering device body 202 captures small particles in the air, such as bacteria, viruses, dust, etc., to ensure that the output air is extremely pure. Then, the purified air is slowly delivered to the top of the bed 1 by the silent fan 205 through multiple air outlets 204. As the air is continuously delivered, the bed 1, an airflow is formed inside the box 2 to flow toward the bed 1, and the gas under the bed 1 flows out from the gap between the flexible transparent screen 801 and the ground, which can prevent the air with bacteria from entering the space where the bed 1 is located through the gap between the flexible transparent screen 801 and the ground. When the soft channel 4, the hard channel 401 and the logistics channel 402 are opened for use, the gas inside the bed 1 will be blown out from the soft channel 4, the hard channel 401 and the logistics channel 402, which can prevent the external gas from entering the interior through the soft channel 4, the hard channel 401 and the logistics channel 402.

[0042] By setting the logistics channel 402, the purpose of entering and exiting items can be achieved, and the opening of the flexible transparent screen 801 can be minimized. Then, when the patient needs to draw blood or infuse, the soft channel 4 can be opened, and then the patient extends and places his arm inside the soft channel 4. A replaceable sponge pad is provided in the soft channel 4 to cushion the patient's arm. At this time, medical staff can perform infusion or blood drawing, blood pressure measurement and other operations on the arm inside the soft channel 4, thereby minimizing the patient's exposure.

[0043] Then the hard channel 401 is located in the middle of the bed 1, corresponding to the patient's waist position, which can fully expose the patient's waist, so that the doctor can perform bone puncture on the patient's waist;

[0044] Example 3

[0045] On the basis of Example 1, a disinfection chamber 3 is opened inside the box body 2, a water pump 301 is installed inside the disinfection chamber 3, a guide tube 302 is connected to the bottom of the water pump 301, a transparent plate 103 is installed between the two support rods 101 on the same side, and the transparent plate 103 is connected to the connecting rod 102, the soft channel 4, the hard channel 401 and the surface of the logistics channel 402, the guide tube 302 is arranged in an L-shaped structure, and the bottom of the guide tube 302 is in contact with the upper surface of the soft channel 4, the hard channel 401 and the logistics channel 402, and the soft channel 4. Two installation grooves 6 are provided on the top of the hard channel 401 and the logistics channel 402. A sealing plate 601 is provided inside the installation groove 6, and the cross-sectional size of the sealing plate 601 matches the corresponding soft channel 4, hard channel 401 and logistics channel 402. The soft channel 4, hard channel 401 and logistics channel 402 are distributed from small to large. A disinfection tube 5 is provided inside the soft channel 4, hard channel 401 and logistics channel 402. An atomizing nozzle 501 is connected to the bottom of the disinfection tube 5, and the disinfection tube 5 is communicated with the guide tube 302.

[0046] Each time after using the soft channel 4, the hard channel 401 and the logistics channel 402, the bacteria or impurities carried by the medical staff's hands will inevitably remain inside the channel. At this time, the disinfectant in the disinfection chamber 3 can be pumped into the guide tube 302 through the water pump 301, and transported to the disinfection tubes 5 on the multiple channels through the guide tube 302, and sprayed out through the atomizing nozzle 501 to disinfect the inside of the multiple channels.

[0047] Example 4

[0048] On the basis of Example 1 and Example 3, further, two movable grooves 7 are provided inside the soft channel 4, the hard channel 401 and the logistics channel 402, and the movable groove 7 is communicated with the installation groove 6 and the disinfection tube 5, the movable groove 7 is connected with an ejection spring 701, one end of the ejection spring 701 is connected with an ejection plate 702, and a through hole 704 is provided on the ejection plate 702, a plurality of rubber blocks 703 are provided on the ejection plate 702, one end of the ejection plate 702 extends to the inside of the installation groove 6, and is provided with an inclined surface.

[0049] When the soft channel 4, the hard channel 401 and the logistics channel 402 are used, the sealing plate 601 can be taken out from the installation groove 6. At this time, the ejection spring 701 in the movable groove 7 starts to reset from the compressed state, so that the elastic force of the ejection spring 701 ejects the ejection plate 702. At this time, the through hole 704 on the ejection plate 702 is staggered with the disinfection tube 5, so as to block the disinfection tube 5, which can prevent medical staff from forgetting to turn off the water pump 301, resulting in the disinfectant sprayed from the atomizing nozzle 501 being scattered from the channel after the channel is opened. The arrangement of multiple rubber blocks 703 can prevent the disinfectant from leaking from the gap between the ejection plate 702 and the movable groove 7;

[0050] After the use of the soft channel 4, the hard channel 401 and the logistics channel 402 is completed, the sealing plate 601 can be reinserted into the installation groove 6. At this time, the sealing plate 601 contacts the inclined surface of the ejection plate 702, and the ejection plate 702 is squeezed into the movable groove 7, so that the ejection spring 701 is squeezed and accumulates elastic force. At the same time, the through hole 704 on the ejection plate 702 corresponds to the position of the disinfection tube 5, and the disinfection tube 5 is reopened to facilitate the subsequent disinfectant to pass through the disinfection tube 5.

[0051] Example 5

[0052] On the basis of Example 1, a first slide groove 8 is opened at the bottom of the box body 2, and a flexible transparent screen 801 is slidably connected inside the first slide groove 8. A second slide groove 802 is opened at the bottom of the box body 2, and the second slide groove 802 is located on the inner side of the first slide groove 8. Two masking screens 803 are slidably connected inside the second slide groove 802. An opening 8011 is opened on the flexible transparent screen 801, and the size and position of the opening 8011 correspond to the size and position of the soft channel 4, the hard channel 401 and the logistics channel 402.

[0053] Since the flexible transparent screen 801 of the existing laminar flow bed is not conducive to protecting the privacy of the patient, the masking screen 803 can be set to shield the internal environment of the bed body 1 from sight after the flexible transparent screen 801 is closed. By setting two masking screens 803, the masking screens 803 can be opened on both sides of the bed body 1 to facilitate patients getting on and off the bed and to be opened when using the soft channel 4, the hard channel 401 and the logistics channel 402, so that medical staff can see the internal environment of the bed body 1 through the flexible transparent screen 801 and the transparent plate 103.
