Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a method for using a neonatal negative pressure isolation incubator. Background Art

[0002] In the neonatal medical care scenario, providing a stable, safe and suitable living environment for neonates is the key to ensuring their healthy growth. Neonates, especially premature infants, have immature physical functions and are extremely sensitive to changes in the external environment. Any slight environmental fluctuation may have a serious impact on their life and health.

[0003] Traditional neonatal negative pressure isolation incubators have many limitations in design and function. In terms of sealing performance, most incubators are difficult to achieve comprehensive and reliable sealing, and unfiltered external air easily enters the interior of the incubator, increasing the risk of neonates being infected with germs and exposed to harmful substances, which is not conducive to the development of their fragile respiratory and immune systems.

[0004] Moreover, the sheets are not firmly fixed, which makes neonates feel uncomfortable when lying down, and the sliding of the sheets affects the posture and safety of neonates. In addition, for neonates who require a specific lying angle, traditional incubators cannot flexibly adjust the inclination angle of the bed board, making it difficult to meet individualized nursing needs. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawbacks in the prior art that it is difficult for the incubator to achieve comprehensive and reliable sealing, unfiltered external air easily enters the interior of the incubator, increasing the risk of neonates being infected with germs and exposed to harmful substances, and the sliding of the sheets affects the posture and safety of neonates, and to propose a method for using a neonatal negative pressure isolation incubator.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A method for using a neonatal negative pressure isolation incubator includes the following steps:

[0008] S1. Placement stage: Open the outer box, lay the sheet on the bed board and fix it through the fixing frame, place the baby and then close the outer box;

[0009] S2. Air circulation stage: Start the intake fan and the exhaust fan, so that the filtered air enters the inner box through the intake pipe, and is discharged to the outer box through the exhaust holes and then discharged through the exhaust pipe, forming a negative pressure isolation space between the inner box and the outer box;

[0010] S3. Transfer stage: Magnetically adsorb the two outer boxes for sealed docking, drive the screw rod to drive the lifting cover to rise to connect the two incubators, and medical staff wear rubber sleeves and insert them into the second operation hole for baby transfer;

[0011] S4. Bed board adjustment stage: The electric push rod drives the moving bar to move. Through the meshing of the gear and the rack, the screw sleeve rotates and pushes the connecting bar to rise and fall, so as to adjust the tilt angle of the bed board.

[0012] As a further improvement of the above technical solution:

[0013] The outer box is hinged to the top of the lifting cover through a hinge. The lifting cover is slidably sleeved on the outer wall of the support seat. The top of the support seat is fixedly connected with the base. The bed board is arranged on the top of the base and is movably connected with the connecting seat through a first universal joint.

[0014] The screw rod is connected with the lifting cover through a connecting block, and the connecting block is slidably limited through a guide rod. The screw rod is driven by a driver in the support seat.

[0015] The connecting component of the adjusting mechanism includes a connecting bar slidably connected to the bottom of the bed board. The connecting bar is in threaded cooperation with the screw sleeve through a second universal joint. A plane is arranged on the outer wall of the second universal joint to limit its rotation along with the screw sleeve.

[0016] The driving component includes a moving bar slidably arranged on the top of the base. The moving bar is driven by an electric push rod, and the screw sleeve is rotatably arranged on the moving bar through a bearing.

[0017] The inner box and the outer box are communicated through an exhaust hole. The first operation hole and the second operation hole are respectively communicated with the inner box through a second connecting tube and a first connecting tube, and the second operation hole is adapted to a rubber sleeve with a stepped groove.

[0018] A sealing gasket is arranged on the outside of the lifting cover. A sealing plate is fixedly connected to the side wall of the support seat to seal the lifting gap, and sealing gaskets are arranged on both the first sealing cover and the second sealing cover.

[0019] Anti-slip protrusions are arranged on the contact surface between the bed board and the fixed frame, and a sponge pad is laid on the top of the bed board.

[0020] In the present invention, for the usage method of the neonatal negative pressure isolation incubator, the magnet adsorption design at the top of the outer box makes the two outer boxes fit tightly. Cooperating with the sealing gasket on the outside of the lifting cover, it greatly reduces the possibility of the baby contacting the unfiltered external air during transfer. The sealing plate on one side of the support seat further strengthens the sealing performance during the lifting process, forming a multi-level protection, providing a highly clean and safe internal environment for the neonate, effectively reducing the infection risk, and ensuring the health of the neonate.

[0021] In the present invention, for the usage method of the neonatal negative-pressure isolation incubator, the intake pipe is connected to an external air blower to continuously send filtered fresh air into the interior of the incubator. The exhaust pipe cooperates with an external exhaust fan to timely discharge the internal air, forming an efficient air circulation, ensuring that the air inside the incubator always remains fresh, providing a good breathing environment for the neonate, helping to maintain the normal function of its respiratory system, and a negative-pressure space is formed between the inner box and the outer box. The air in the inner box is discharged to the outer box through the exhaust holes and then discharged through the exhaust pipe, effectively avoiding the mixing of internal and external air, improving the air quality inside the incubator, reducing the impact of external pollutants on the neonate, and creating a relatively independent and clean microenvironment for the neonate;

[0022] In the present invention, for the usage method of the neonatal negative-pressure isolation incubator, through the coordinated operation of the adjustment mechanism, the driving component and the connecting component, precise adjustment of the inclination angle of the bed board is achieved. The electric push rod drives the moving bar to move, driving the screw sleeve to move and rotate, and then through the connecting bar, one end of the bed board is raised to realize the adjustment of the inclination angle, making the operation simple and convenient.

[0023] In the present invention, external pollution is effectively isolated through a multiple sealing structure. In combination with the efficient air circulation and isolation design, the internal air is ensured to be pure. The operation hole is flexibly sealed and equipped with a rubber sleeve for adaptation, taking into account both operation convenience and safety. The bed body is comfortable and stable, the inclination angle can be flexibly adjusted to meet various needs, the lifting system is stable and precise, comprehensively ensuring the safety and comfort of the neonate.
