Description

Technical Field

[0001] This utility model relates to a body fluid collection device, specifically a newborn body fluid collection device, and belongs to the field of newborn body fluid collection technology. Background Technology

[0002] Neonatal fluid collection refers to the medical procedure of obtaining samples of body fluids such as blood, urine, cerebrospinal fluid, and saliva from a newborn through specific methods and techniques for purposes such as disease diagnosis, health assessment, and screening for genetic metabolic diseases. Appropriate body fluid collection equipment is used during this process.

[0003] The existing utility model with authorization announcement number CN220089511U discloses a convenient pet bodily fluid collection device, which can easily and conveniently collect pet saliva samples. After collecting saliva by attaching an absorbent material to the collection stick, it is connected to a filter and placed in a collection tube for filtration and collection. The saliva is then collected in a storage tube and thoroughly mixed with saliva preservation solution. The collected saliva sample is used for medical testing to provide a basis for subsequent medical diagnosis. The convenient pet saliva collection device described in this utility model can be collected by pet owners themselves, making it simple and efficient to collect pet saliva samples.

[0004] While the above-mentioned technical solution allows for simple and efficient collection of saliva samples, the quality of the samples is easily affected by external temperature, and the lack of an intelligent temperature control structure for the storage environment makes it difficult to guarantee the long-term quality of neonatal body fluid samples. Therefore, this paper proposes a neonatal body fluid collection device. Utility Model Content

[0005] This invention proposes a neonatal body fluid collection device to solve the problem that the lack of an intelligent temperature control structure for the storage environment in the existing technology makes it difficult to guarantee the long-term quality of neonatal body fluid samples after sampling.

[0006] This utility model is achieved through the following technical solution: a neonatal body fluid collection device, including an insulated box, an insulated cover is movably hinged to the back of the insulated box, and an intelligent temperature control mechanism for samples is provided inside the insulated box; The intelligent temperature control mechanism for the sample includes two sampling racks, each of which has several identical sampling cotton swabs inserted inside. The interior of the insulation box is provided with a hollow support, and the inner wall of the hollow support and the inner wall of the insulation box are connected by four fastening bolts. The inner wall of the hollow support is fixedly connected to a semiconductor cooling chip, two temperature sensors and a cooling fan. The left side of the semiconductor cooling chip is fixedly connected to a heat dissipation fin, and the front of the insulation box is fixedly connected to a button controller.

[0007] Specifically, the bottom surface of the heat preservation cover is in contact with the upper surface of the heat preservation box, the outer surface of each sampling rack is in contact with the inner wall of the heat preservation box, the outer surface of the hollow bracket is in contact with the inner wall of the heat preservation box, the semiconductor cooling chip, the two temperature sensors and the cooling fan are all electrically connected to the button controller through wires, a handle is fixedly connected to the upper surface of the heat preservation cover, and a first anti-slip sleeve is fixedly connected to the outer surface of the handle.

[0008] Furthermore, the front of the insulation cover is fixedly connected to two fixing rods, and the front of the insulation box is fixedly connected to two limiting rods.

[0009] Each of the fixed rods has a rotatable limit plate rotatably connected to its outer surface, and the interior of each limit plate is engaged with the outer surface of the limit rod.

[0010] Preferably, each of the fastening bolts has a washer fitted on its outer surface, and the right side of each washer is in contact with the outer surface of the hollow bracket.

[0011] Furthermore, a second anti-slip sleeve is fixedly connected to the outer surface of each sampling cotton swab, and a plurality of identical anti-slip protrusions are fixedly connected to the outer surface of each second anti-slip sleeve.

[0012] This invention provides a neonatal body fluid collection device, which has the following beneficial effects: This neonatal body fluid collection device, through the coordinated operation of an insulated box, an insulated cover, a sampling rack, sampling swabs, a perforated support, fastening bolts, a temperature sensor, a semiconductor cooling chip, heat dissipation fins, a cooling fan, and a button controller, achieves excellent thermal insulation. The sampling swabs collect saliva or blood samples from the newborn and are stored on the sampling rack. The temperature sensor monitors the ambient temperature inside the insulated box. When this temperature exceeds the preset temperature range of the button controller, the controller automatically powers on the semiconductor cooling chip, initiating cooling on its right side. Simultaneously, the controller powers on the cooling fan, which, in conjunction with the heat dissipation fins, dissipates heat from the heating surface on the left side of the semiconductor cooling chip. This process continues until the temperature sensor detects that the temperature inside the insulated box is below the midpoint of the preset temperature range. This significantly controls the low-temperature storage of the samples collected on the sampling swabs, greatly extending the high-quality storage time of neonatal body fluid samples. It avoids the problem of inconsistent long-term storage quality of neonatal body fluid samples due to the lack of an intelligent temperature control structure. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-5 This utility model provides a neonatal body fluid collection device, including an insulated box 1, with an insulated cover 2 hinged to the back of the insulated box 1. Both the insulated box 1 and the insulated cover 2 are made of materials with good heat insulation properties. The insulated box 1 is equipped with a sample intelligent temperature control mechanism 3, which includes two sampling racks 301. Each sampling rack 301 has several identical sampling swabs 302 attached to its interior. The sampling swabs 302 can collect liquid samples such as blood or saliva from the newborn. The bottom surface of the insulated cover 2 is in contact with the upper surface of the insulated box 1, and the outer surface of each sampling rack 301 is in contact with the inner wall of the insulated box 1. A handle 7 is fixedly connected to the upper surface of the insulated cover 2, and a first anti-slip sleeve 8 is fixedly connected to the outer surface of the handle 7. The handle 7 facilitates the upward flipping of the insulated cover 2, and the first anti-slip sleeve 8 increases the anti-slip effect of the outer surface of the handle 7.

[0017] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4The interior of the insulation box 1 is provided with a hollow support 303. The outer surface of the hollow support 303 is in contact with the inner wall of the insulation box 1. The inner wall of the hollow support 303 and the inner wall of the insulation box 1 are connected by four fastening bolts 304. The front of the insulation cover 2 is fixedly connected with two fixing rods 4, and the front of the insulation box 1 is fixedly connected with two limiting rods 5. By setting the fixing rods 4, a rotation base surface can be provided for other limiting structures, thereby increasing the flexibility of the use of the limiting structure. By setting the limiting rods 5, the limiting structure can be limited.

[0018] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner wall of the hollow bracket 303 is fixedly connected to a semiconductor cooling chip 306, two temperature sensors 305 and a cooling fan 308. The outer surface of each fixed rod 4 is rotatably connected to a limiting plate 6. The inside of each limiting plate 6 is engaged with the outer surface of the limiting rod 5. By setting the limiting plate 6, it can rotate around the outer surface of the fixed rod 4 and engage with the outer surface of the limiting rod 5, thereby temporarily locking the relative position of the insulation box 1 and the insulation cover 2 and increasing the airtightness after the two are closed.

[0019] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The left side of the semiconductor cooling chip 306 is fixedly connected to a heat dissipation fin 307. Each fastening bolt 304 has a washer 9 on its outer surface. The right side of each washer 9 is in contact with the outer surface of the hollow bracket 303. By setting the washer 9, it can be placed between the hollow bracket 303 and the fastening bolt 304 and increase the contact area between the two, thereby increasing the fastening effect of the fastening bolt 304.

[0020] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 5A button controller 309 is fixedly connected to the front of the insulation box 1. The button controller 309 can be an MCU or an Arduino series. It is small in size, low in cost and low in power consumption, and suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. The semiconductor cooling chip 306, two temperature sensors 305 and the cooling fan 308 are all electrically connected to the button controller 309 through wires. A second anti-slip sleeve 10 is fixedly connected to the outer surface of each sampling cotton swab 302. Several identical anti-slip protrusions 11 are fixedly connected to the outer surface of each second anti-slip sleeve 10. By setting the anti-slip protrusions 11, the anti-slip property of the outer surface of the second anti-slip sleeve 10 can be increased. By setting the second anti-slip sleeve 10 and the anti-slip protrusions 11, the anti-slip property of the outer surface of the sampling cotton swab 302 can be increased together, thereby increasing the convenience of picking up and putting down the sampling cotton swab 302.

[0021] When using this utility model: First, when it is necessary to use the sampling swab 302 to sample the body fluid of a newborn, rotate the two limiting plates 6 around the fixing rod 4 and move them away from the limiting rod 5. Then, use your hand to lift the handle 7 to flip up the heat preservation cover 2. After that, pinch the second anti-slip sleeve 10 and anti-slip protrusion 11 on the unused sampling swab 302 and pull the sampling swab 302 out of the sampling frame 301 to use the sampling swab 302.

[0022] After using the sampling swab 302 to collect an appropriate amount of neonatal bodily fluid, simply insert the sampling swab 302 into the appropriate position inside the sampling frame 301. When it is necessary to clean the sampling frame 301, simply remove the entire sampling frame 301 from the incubator 1 to clean the sampling frame 301 separately.

[0023] When the temperature sensor 305 detects that the ambient temperature inside the incubator 1 is higher than the preset temperature range of the button controller 309, the button controller 309 automatically controls the semiconductor cooling chip 306 to be powered on and the right side to start cooling. At the same time, the button controller 309 controls the cooling fan 308 to be powered on and works with the heat dissipation fins 307 to dissipate heat from the heating surface on the left side of the semiconductor cooling chip 306 until the temperature sensor 305 detects that the temperature inside the incubator 1 is lower than the midpoint of the preset temperature range of the button controller 309. This greatly controls the low-temperature storage effect of the sample taken on the sampling swab 302, and greatly increases the high-quality storage time of neonatal body fluid samples after sampling. The design of the entire neonatal body fluid collection device effectively solves the problem that the storage quality of neonatal body fluid samples is difficult to guarantee for a long time due to the lack of an intelligent temperature control structure for the storage environment.
