Description

Technical Field

[0001] The invention relates to the technical field of neonatal medical incubators, and in particular to a neonatal incubator with variable space. Background Art

[0002] A neonatal incubator, also known as an infant incubator, is a key medical device that provides life support for premature, low-birth-weight or sick newborns. It simulates the maternal uterine environment and creates a safe and stable growth space for fragile little lives by precisely controlling temperature, humidity and oxygen concentration, helping them through the initial fragile stage of life.

[0003] Traditional incubators usually adopt a rectangular structure of fixed size. Although it can meet basic care needs, its fixed space also brings a series of problems:

[0004] 1. Low space utilization. Newborns experience rapid growth and development in the incubator, and their body shape changes significantly. Fixed space cannot adapt to such changes. For small newborns, too large a space is not conducive to keeping warm and maintaining a stable environment. For relatively large newborns, the narrow space will restrict their limb activities, which is not conducive to the development of muscle and motor coordination ability.

[0005] 2. Nursing operations are inconvenient. The fixed space limits the operating space of medical staff, especially when changing diapers, wiping the body, medical operations and other care are required. It increases the difficulty and time of operations, and also increases the risk of newborns catching cold and infection. Summary of the invention

[0006] The purpose of the present invention is to provide a newborn incubator with variable space. The bottom box assembly is connected to the bottom support based on an automatically liftable bottom support, and a follow-up telescopic pad assembly is used in conjunction with the top cover component itself. The top cover component is not only a telescopic structure, but can also form a plug-in fit with the hollow columns at the corners of the side supports, so that the side supports and the side telescopic supports can form a telescopic adjustment action on the basis of safety and comfort.

[0007] The objective of the present invention is achieved through such a technical solution. A space-variable neonatal incubator comprises a bottom frame member, a bottom support assembly, a bottom box assembly, a follow-up telescopic pad assembly and a top cover member. The bottom support assembly comprises a bottom support, the bottom box assembly comprises a side telescopic support, the follow-up telescopic pad assembly comprises a middle solid pad, a side telescopic pad and a bottom cover, and the top cover member comprises a top solid cover;

[0008] The outer bottom of the bottom bracket is slidably connected to the middle and upper part of the bottom frame member, and the side telescopic brackets are symmetrically connected to the side ends of the bottom bracket. The outer bottom of the bottom bracket is symmetrically slidably connected to the side brackets that can be telescopically moved synchronously. The side brackets on the same side are fixedly connected to the other end of the side telescopic brackets. Hollow columns are vertically fixed at the corners of the outer sides of each set of side brackets.

[0009] A sliding channel is provided on the outer side of the bottom body of each set of side supports, the middle solid pad is bonded and fixed to the inner bottom end of the bottom support, the bottom cover is transversely fixed to the outer bottom end of the side support, and a reel is elastically screwed inside each set of bottom covers, one end of the side telescopic pad is bonded and fixed to the side end of the middle solid pad, and the other end passes through the sliding channel and is rolled and fixed to the outside of the reel;

[0010] A C-shaped inner buckle is fixed to the top of each group of hollow columns, and a top telescopic cover is connected between the symmetrically distributed top solid covers. A top insert sleeve is vertically fixed to the corners of the outer end of each group of top solid covers, and the inner bottom end of the top insert sleeve can be plugged into and matched with the inner buckle.

[0011] The use process of the technical solution of the present invention is as follows:

[0012] The bottom bracket can be automatically raised and lowered based on the chassis components, making it convenient for different working environments;

[0013] Furthermore, since the side supports are not only connected to the bottom support through the side telescopic supports, but the outer bottom of the side supports is also slidably connected to the outer bottom of the bottom support, the bottom box assembly can not only stably move along with the lifting and lowering of the bottom support, but also realize the stable synchronous telescopic movement of the side supports distributed on a scale, thereby achieving safe telescopic changes of the entire cavity space formed by the bottom support, the side telescopic supports and the connection of the side supports;

[0014] The middle solid pad, which plays a role of fixed connection, is located at the inner bottom end of the bottom bracket. One end of the side telescopic pad is fixed to the side end of the middle solid pad, and the other end is fixed and wound around the outside of the elastically rotating reel, so that the reel can pull the side telescopic pad away from the middle solid pad, so that when the side bracket is telescopically moved, the side telescopic pad is always in a flattened and straightened state.

[0015] The top cover member is used as a cover shell as a whole, and the cover is connected to the bottom support, the side telescopic support and the upper end of the cavity formed by the side telescopic support;

[0016] Since a top insert sleeve that matches the inner insert buckle is fixed at the outer end corner of each group of top solid covers, after the top cover component is connected with the inner insert buckle through the top insert sleeve, as the side support moves relative to the bottom support, the cover shell composed of the top solid cover and the top telescopic cover can also achieve telescopic changes.

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) The telescopic structure composed of the bottom support and the side support through the side telescopic support of the present invention can not only realize the spatial change of the entire cavity composed of the bottom support, the side telescopic support and the side support, but also solve the problem of poor comfort caused by the structure of the side telescopic support itself while realizing the cavity change between the side telescopic support and the bottom support by using the side telescopic support through the follow-up telescopic pad assembly. By elastically rotating the reel inside the bottom cover arranged at the outer bottom end of each group of side supports, and fixing one end of the side telescopic pad to the outer edge of the reel and then winding it, and fixing the other end to the side end of the middle solid pad fixed to the inner bottom end of the bottom support, the structure formed by connecting the side telescopic pad and the middle solid pad can move with the telescopic movement of the side support, and always keep the state of flatly covering the bottom surface of the entire cavity composed of the bottom support, side telescopic support and the side support, thereby eliminating the disadvantage of poor comfort caused by the telescopic structure of the side telescopic support itself;

[0019] (2) The purpose of fixing the hollow column at the corners on the outside of each group of side supports of the present invention is not only to facilitate the plug-in fit between the inner plug-in buckle fixed on the top of the hollow column and the top plug-in sleeve at the corners on the outside of the top fixed cover, so that the top cover component can be buckled on the top of the bottom support, the side telescopic support and the side support to form the top of the entire cavity through the top plug-in sleeve; at the same time, the hollow column arranged at the corners on the outside of the side support can also provide an operating space for the side telescopic pad, so that the sliding channel can be completely opened at the corner position of the bottom end body of the side support, and at the same time provide an installation position for the bottom cover, so that the two ends of the side telescopic pad slidably connected in the sliding channel are kept at a certain distance from the inner wall of the hollow column, so that the sliding of the side telescopic pad in the sliding channel will not be stuck.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0045] like Figure 1-Figure 15As shown, a space-variable neonatal incubator, the middle and upper part of the bottom frame member 1 is slidably connected with a bottom support 201, and the bottom support 201 can automatically rise and fall based on the bottom frame member 1, and the side telescopic supports 302 are symmetrically connected to the side ends of the bottom support 201, and the outer bottom of the bottom support 201 is symmetrically slidably connected with the side supports 301 that can be telescopically moved synchronously, and the side supports 301 on the same side are fixedly connected to the other ends of the side telescopic supports 302, and hollow columns 303 are vertically fixed at the corners of the outer sides of each group of side supports 301, and the side telescopic supports 302 are connected between the side supports 301 and the bottom support 201, so that as the side supports 301 are telescopically moved, the bottom support 201, the side telescopic supports 302 and the side supports 301 as a whole cavity can be telescopically changed;

[0046] A sliding channel 401 is provided on the outer side of the bottom body of each set of side supports 301, the middle solid pad 402 is glued and fixed to the inner bottom end of the bottom support 201, the bottom cover 404 is transversely fixed to the outer bottom end of the side support 301, and a reel 412 is elastically screwed inside each set of bottom covers 404, one end of the side telescopic pad 403 is glued and fixed to the side end of the middle solid pad 402, and the other end passes through the sliding channel 401 and is rolled and fixed to the outside of the reel 412. Under the rotational elastic force of the reel 412 itself, the side telescopic pad 403 wound between the outside of the reel 412 and the middle solid pad 402 can be in a straightened and tightened state at all times as the bottom support assembly 2 is stretched and contracted, and the part of the side telescopic pad 403 wound around the outside of the reel 412 is sufficient to support the side telescopic pad 403 to stretch and contract as the bottom support assembly 2 is stretched and contracted.

[0047] A C-shaped inner buckle 501 is fixed to the top of each set of hollow columns 303, and a top telescopic cover 503 is connected between the symmetrically distributed top fixed covers 502. A top insert sleeve 505 is vertically fixed to the corner of the outer end of each set of top fixed covers 502, and the inner bottom end of the top insert sleeve 505 can be plugged into and matched with the inner buckle 501;

[0048] Here’s how it works:

[0049] The bottom bracket 201 can be automatically raised and lowered based on the bottom frame member 1, so it is convenient to be used in different working environments;

[0050] Furthermore, since the side support 301 is not only connected to the bottom support 201 through the side telescopic support 302, but the outer bottom of the side support 301 is also slidably connected to the outer bottom of the bottom support 201, the bottom box assembly 3 can not only stably move along with the lifting and lowering of the bottom support 201, but also realize the stable synchronous telescopic movement of the side support 301, thereby achieving the safe telescopic change of the entire cavity space formed by the connection of the bottom support 201, the side telescopic support 302 and the side support 301;

[0051] Considering that the telescopic structure of the side telescopic support 302 itself will form a continuous concave-convex surface, if a transition zone is not provided at the top of the side telescopic support 302, it will affect the comfort of use, so a follow-up telescopic pad assembly 4 is provided;

[0052] The middle solid pad 402 and the side expansion pad 403 are made of antibacterial soft material;

[0053] The middle solid pad 402, which plays a role of fixed connection, is located at the inner bottom end of the bottom bracket 201. Since one end of the side telescopic pad 403 is glued and fixed to the side end of the middle solid pad 402, and the other end is fixed and wound around the outside of the elastically rotating reel 412, the reel 412 can form a pulling motion towards the side telescopic pad 403 away from the middle solid pad 402, so that when the side bracket 301 is telescopically moved, the side telescopic pad 403 is always in a flattened and straightened state, so that when the bottom bracket 201, the side telescopic bracket 302 and the side bracket 301 are telescopically adjusted in space, the side telescopic pad 403 can form the inner bottom of the cavity formed by the bottom bracket 201, the side telescopic bracket 302 and the side bracket 301 through its own changes.

[0054] In addition, the middle solid pad 402 can be removed from the bottom bracket 201, and the side telescopic pad 403 can also be removed as a whole along with the bottom cover 404, so that the middle solid pad 402 and the side telescopic pad 403 can be replaced conveniently;

[0055] The top cover member 5 is used as a cover shell as a whole, and is connected to the bottom support 201, the side telescopic support 302 and the upper end of the cavity formed by the side telescopic support 302;

[0056] Since the top telescopic cover 503 is connected between the symmetrically distributed top fixed covers 502, the top fixed covers 502 and the top telescopic cover 503 can also achieve telescopic changes;

[0057] Since a top insert sleeve 505 that matches the inner insert buckle 501 is fixed at the outer end corner of each group of top fixing covers 502, after the top cover component 5 is plugged into the inner insert buckle 501 through the top insert sleeve 505, as the side support 301 moves telescopically relative to the bottom support 201, the cover shell composed of the top fixing cover 502 and the top telescopic cover 503 can also achieve telescopic changes.

[0058] The specific structure of the chassis component 1 and the bottom bracket component 2 is as follows: Figure 2 , Figure 3 and Figure 4 As shown, a top sliding sleeve 103 is fixedly connected to the middle of the top of the bottom frame 101 of the I-shaped structure, and medical casters 102 are fixedly installed in groups at the bottom end of the bottom frame 101;

[0059] The medical casters 102 can not only support the movement of the entire chassis member 1, but each set of medical casters 102 is also provided with a self-locking function, which facilitates stable and safe position maintenance;

[0060] The top sliding sleeve 103 is a square cavity structure with an open upper end;

[0061] The connecting sleeve 202 is fixed to the middle of the bottom end of the bottom bracket 201, the sliding sleeve 203 is fixedly connected to the bottom end of the connecting sleeve 202, and the two sets of side brackets 301 are slidably connected with the connecting sleeve 202, and the outline size of the connecting sleeve 202 is larger than the outline size of the sliding sleeve 203, which can not only improve the stability of the sliding sleeve 203, the connecting sleeve 202 and the bottom bracket 201 as a whole structure, but also provide the transmission space of the sliding mechanism connected to the side bracket 301 to the greatest extent, thereby improving the moving stroke of the side bracket 301;

[0062] The inner surface of the sliding sleeve 203 is slidably connected to the outer surface of the top sliding sleeve 103. Top seats 204 are fixed in pairs on both sides of the inner top of the sliding sleeve 203. A lifting slide post 205 is fixed at the bottom end of each group of top seats 204. A cross connecting frame 207 is fixedly connected to the bottom end of each group of lifting slide posts 205. Inner sliding blocks 206 are fixed in pairs on both sides of the inner upper end of the top sliding sleeve 103. The lifting slide posts 205 on the same side are slidably connected to the inner sliding blocks 206.

[0063] The screw top seat 208 is fixedly installed in the middle of the inner top of the top sliding sleeve 103, and the servo motor 209 is fixedly installed at the inner bottom of the top sliding sleeve 103. The top of the lifting screw 210 is rotatably connected to the screw top seat 208, and the bottom is fixedly connected to the rotating shaft of the servo motor 209. The middle of the main body of the cross connecting frame 207 is fixedly installed with a screw slider 211, and the screw slider 211 is matched and connected in the lifting screw 210;

[0064] After the servo motor 209 is started, it can drive the rotation of the lifting screw 210. The lifting screw 210 and the screw slider 211 form a coordinated transmission, which can enable the cross-connecting frame 207 and the lifting slide column 205 fixedly connected to the cross-connecting frame 207 to form a moving action along the sliding cooperation formed with the inner slider 206, thereby forming a lifting and moving action of the sliding sleeve 203 relative to the top sliding sleeve 103, driving the bottom support 201 fixedly connected to the sliding sleeve 203 through the connecting sleeve 202 and the bottom box assembly 3 connected to the bottom support 201 to automatically lift and move.

[0065] The specific structure of the bottom box assembly 3 is as follows: Figure 5 , Figure 6 and Figure 7 As shown, the outer bottom end of each set of side supports 301 is fixed with a base 304 in pairs, and telescopic slides 306 are fixedly installed on both sides of the main body of the connecting sleeve 202, and there is a certain height difference between the two sets of telescopic slides 306. The side of each set of bases 304 is laterally fixedly connected with a telescopic slide column 305, and the other end of the telescopic slide column 305 is slidably connected to the telescopic slide 306, so that the telescopic slide columns 305 at the bottom ends of the two sets of side supports 301 can be formed to be non-intersecting with each other on the left and right sides.

[0066] The other ends of the telescopic sliding posts 305 on the same side are fixedly connected with inner connecting plates 308, and both sets of inner connecting plates 308 are located inside the connecting sleeve 202, and the telescopic lead screw slider 309 is installed and fixed in the body of the inner connecting plate 308;

[0067] The inner cavity of the connecting sleeve 202 is provided with a telescopic screw 310 arranged vertically and screwed therein, and the telescopic screw slider 309 on the same side is cooperatively connected with the telescopic screw 310;

[0068] A telescopic screw seat 311 is provided in the inner cavity formed by the connection of the connecting sleeve 202 and the base 201. The end of the telescopic screw 310 is rotatably connected to the telescopic screw seat 311. The telescopic screw seat 311 is installed and fixed on the bottom surface of the base 201 or the main body of the connecting sleeve 202 according to actual conditions.

[0069] A synchronous toothed belt pulley 312 is also fixed at the end position on the same side of the telescopic screw 310, and the synchronous toothed belt pulley 312 is located outside the connecting sleeve 202, and the synchronous toothed belt 313 is sleeved and installed between the synchronous toothed belt pulleys 312;

[0070] The telescopic motor 307 is fixedly mounted on the outer wall of the connecting sleeve 202, and the other side shaft end of a set of telescopic screws 310 passes through the side wall of the connecting sleeve 202 and is fixedly connected to the rotating shaft of the telescopic motor 307;

[0071] After the telescopic motor 307 is started, it can drive the active rotation of a set of telescopic screws 310 on the lower side. The two sets of telescopic screws 310 can rotate synchronously and in the same direction through the transmission cooperation formed between the synchronous toothed belt wheel 312 and the synchronous toothed belt 313;

[0072] Furthermore, since the cooperation between the telescopic screw slider 309 and the telescopic screw 310 can be selected to be left-handed or right-handed, when the two sets of telescopic screws 310 rotate synchronously and in the same direction, the cooperation transmission formed by the telescopic screw 310 and the telescopic screw slider 309 drives the two sets of telescopic screw sliders 309 at different heights to keep moving toward each other synchronously, so that the two sets of inner connecting plates 308 and the two sets of side supports 301 connected to the inner connecting plates 308 through the telescopic slide column 305 move toward each other synchronously, thereby forming the side supports 301 to be adjusted by the spatial change of the side telescopic supports 302 relative to the bottom support 201;

[0073] Furthermore, during operation, the two sets of inner connecting plates 308 will not interfere with each other even if they overlap when viewed from above, due to the safe height difference.

[0074] The specific structure of the follow-up telescopic pad assembly 4 is as follows Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the bottom of both side ends of the middle solid pad 402 and the bottom of the inner end of the side telescopic pad 403 are both laterally fixedly connected with a mother adhesive tape 405, and the two connected sets of mother adhesive tapes 405 are not adhered to each other, and the sub-adhesive tape 406 is located on the upper part of the connected mother adhesive tapes 405, and after the sub-adhesive tape 406 is adhered to the two connected sets of mother adhesive tapes 405, the top surface of the sub-adhesive tape 406 is just flush with the top surfaces of the middle solid pad 402 and the side telescopic pad 403, and no uneven position is formed due to the connection between the side telescopic pad 403 and the middle solid pad 402;

[0075] Auxiliary rotating seats 407 are fixed on both sides of the inner top of the bottom cover 404, and side rotating sleeves 408 are symmetrically sleeved and fixed on the outside of the two ends of the reel 412. The auxiliary rotating seats 407 can form a complete circle structure together with the semi-cylindrical cavity structure at the bottom of the bottom cover 404, and the side rotating sleeves 408 are rotatably connected in the inner circle formed by the auxiliary rotating seats 407 and the bottom cover 404;

[0076] The purpose of providing the side rotation sleeve 408 is to provide a limit for the side telescopic pad 403 wound outside the reel 412;

[0077] The openings on both sides of each bottom cover 404 are fixedly connected with side covers 409, and the inner shaft 410 is fixedly connected between the coaxially opposite side covers 409, and the inner shaft 410 passes through the inner middle part of the reel 412, and coil springs 411 are clamped and installed between the inner holes at both ends of the reel 412 and the outer surface of the inner shaft 410, and the outer surface of the inner shaft 410 and the inner hole of the reel 412 are provided with clamping grooves that match the position of the end of the coil spring 411, so that the two ends of the coil spring 411 can be clamped and installed between the outer surface of the inner shaft 410 and the inner hole of the reel 412 respectively;

[0078] Under the action of the elastic rotation torque of the winding drum 412 relative to the inner shaft 410 formed by the winding spring 411, the side telescopic pad 403 wound and fixed outside the winding drum 412 can be always in a tensioned state relative to the middle solid pad 402;

[0079] When the side support 301 contracts to the minimum or maximum position relative to the bottom support 201 , the supporting elastic force provided by the coil spring 411 is still sufficient to support the side telescopic pad 403 to be in a taut and flat state relative to the middle solid pad 402 .

[0080] The specific structure of the top cover member 5 is as follows Fig.12 As shown, an operation hole 504 is provided on the outer side of each set of top fixing covers 502, so that an operator can reach into the top fixing covers 502 through the operation hole 504 to perform nursing operations on the newborn;

[0081] Furthermore, the top fixing cover 502 is made of transparent material, which is convenient for medical staff to observe the newborn.

[0082] The specific structure of the ventilation and circulation component 6 is as follows: Fig.13 , Fig.14 and Fig.15 As shown, the ventilation holes 601 are arranged in pairs on the inclined surface of the upper end of the inner buckle 501, and a ventilation cyclone 602 is fixedly connected to each set of ventilation holes 601;

[0083] The outer bottom end of the top sliding sleeve 103 is sleeved and fixed with a bottom fixing plate 603, the outer bottom end of the sliding sleeve 203 is sleeved and fixed with a top fixing plate 604, the air blowing shock-absorbing telescopic cover 605 is sleeved on the outer side of the top sliding sleeve 103, and the top end of the air blowing shock-absorbing telescopic cover 605 is fixedly connected to the top fixing plate 604, and the bottom end of the air blowing shock-absorbing telescopic cover 605 is fixedly connected to the bottom fixing plate 603;

[0084] One-way air inlet holes 606 are connected to both sides of the bottom of the air-blowing shock-absorbing telescopic cover 605, and one-way air outlet holes 607 are connected to the other two sides of the bottom of the air-blowing shock-absorbing telescopic cover 605. When the air-blowing shock-absorbing telescopic cover 605 is compressed, the gas is only allowed to be discharged outward from the one-way air outlet holes 607 and inhaled inward from the one-way air inlet holes 606.

[0085] The outlet position of each group of one-way air outlet holes 607 is connected to an air outlet tee 608, and a corner socket 609 of a right-angle corner structure is fixedly installed inside each group of hollow columns 303. A connecting hose 610 is connected between the outlet of the air outlet tee 608 and the inlet of the corner socket 609 on the same side.

[0086] The inlet of the air blowing pipe 611 is plugged and matched with the outlet of the corner plug socket 609. When the top cover component 5 uses the top plug sleeve 505 to plug and match with the inner plug buckle 501 at the top of the hollow column 303, the inlet position of the air blowing pipe 611 on the same side can just form a plug-in match with the outlet position of the corner plug socket 609, so that after the top cover component 5 and the bottom box component 3 are assembled, the air blowing pipe 611 can also be connected with the inner cavity of the air blowing shock-absorbing telescopic cover 605 by plugging with the corner plug socket 609;

[0087] When the bottom bracket 201 is lifted and lowered relative to the top sliding sleeve 103, the air-blowing shock-absorbing telescopic cover 605 can be compressed and released synchronously. The air-blowing shock-absorbing telescopic cover 605 can realize the shock-absorbing effect of the bottom bracket 201 telescopic top seat relative to the top sliding sleeve 103 on the one hand, and can form the air exchange in the inner cavity of the air-blowing shock-absorbing telescopic cover 605 on the other hand;

[0088] When the air-blowing shock-absorbing telescopic hood 605 is compressed and released, the air in the external clean space can be absorbed and transported to the top solid hood 502 through the air-blowing shock-absorbing telescopic hood 605, replacing the turbid air in the cavity composed of the bottom support assembly 2, the bottom box assembly 3 and the top cover component 5, that is, the incubator. After the air flow is blown out from the air blowing pipe 611, it can also drive the rotation of the air blowing fan 612. The air blowing fans 612 evenly distributed on both sides of the top solid hood 502 are used to further improve the air circulation in the cavity composed of the bottom support assembly 2, the bottom box assembly 3 and the top cover component 5, thereby keeping the air inside the incubator fresh.

[0089] Preferably, a control panel is installed on one side of the base support 201 for easy operation by medical staff. The servo motor 209 and the telescopic motor 307 are electrically connected to the control panel. The heating wires used for the heating device are distributed on the outer walls of the side support 301 and the base support 201. Temperature sensors can be installed in the inner cavity of the side support 301 or the base support 201 to achieve constant temperature control.
