Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a shoulder warming device for critically ill patients. Background Technology

[0002] In clinical nursing practice, traditional patient gowns, as a basic feature of medical institutions, primarily function to identify a patient's department and identity information. Their design is typically simple and easy to put on and take off, suitable for conscious inpatients with a certain degree of self-care ability. However, for critically ill patients in the ICU (Intensive Care Unit), these gowns can no longer meet their specific nursing needs.

[0003] ICU patients, due to the severity of their condition, often require multiple invasive procedures such as tracheotomy, central venous catheterization, and urinary catheterization, and are accompanied by numerous indwelling tubes (such as IV lines and drainage tubes). Traditional patient services have the following significant limitations:

[0004] Structural limitations: Patient gowns are mostly one-piece or loose-fitting long gowns, which are difficult to adapt to the needs of frequent medical operations and are prone to damage or contamination due to repeated putting on and taking off.

[0005] Insufficient warmth: Critically ill patients have metabolic disorders and decreased thermoregulation ability, so they need to focus on protecting the neck and shoulders (such as the tracheotomy site). However, traditional patient gowns lack targeted warmth design, and the indwelling tubes prevent the clothing from fitting the skin, which leads to increased heat loss from the shoulders.

[0006] In addition, although there are existing warm patient gowns, they are a one-piece structure, which is generally difficult to disinfect after use by critically ill patients. Disposing of patient gowns containing many electrical components increases medical costs, making them impractical.

[0007] Therefore, it is necessary to propose a shoulder warming device for critically ill patients to solve the above problems. Summary of the Invention

[0008] (a) Technical problems to be solved

[0009] The purpose of this invention is to address the problems of traditional patient gowns, such as the difficulty of frequent dressing and doffing due to their one-piece design, easy damage and contamination, lack of warmth, and the need for special protection of the shoulder and neck areas (such as the tracheostomy site) due to metabolic disorders, which are often not specifically addressed by traditional designs and the presence of indwelling tubes that prevent the clothing from fitting properly and exacerbate heat loss. In addition, existing one-piece warm patient gowns are difficult to disinfect, and the inclusion of electrical components significantly increases medical costs, failing to meet both practicality and hygiene safety standards. This invention provides a shoulder warming device for critically ill patients.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figure 1-4A shoulder warming device for critically ill patients includes a shawl 10 and a heating device 30. The bottom of the shawl 10 is bonded with an insulation layer 11, which is made of polyester cotton. The insulation layer 11 uses a polyester cotton composite aerogel material with a density of 80 kg / m³, a thickness of 5 mm, a thermal conductivity ≤0.025 W / (m·K), and a vertical compressive strength ≥20 kPa (compliant with GB / T17511-2021 medical textile standards). It has passed the EN 14932:2017 medical textile flammability test, with an oxygen index ≥30%. A snap button 14 is attached to the front of the shawl 10. Two binding straps 20 are symmetrically sewn to the bottom of the shawl 10. The binding straps 20 are made of a blend of 75% nylon and 25% spandex, with a tensile strength ≥30 kPa. N / cm², the top of the binding strap 20 is sewn with an extension 23, and the inner side of the extension 23 is fitted with a male snap 14; the snap 14 is a YKK #5 resin button, the male and female snap mating gap is ≤0.3 mm, and the surface friction coefficient is ≥0.6. One end of the binding strap 20 is sewn with an elastic band 21, and the inner side of the end of the elastic band 21 is sewn with a male Velcro 22. The end of the other binding strap 20 is sewn with a female Velcro 22.

[0042] In this embodiment, by setting up a shawl 10 and with the cooperation of two restraint straps 20, the patient's head can be placed in the middle of the shawl 10. The two restraint straps 20 are passed through the armpits and connected by Velcro 22. The front of the shawl 10 is connected to the restraint straps 20 by snaps 14. This greatly reduces the number of times the patient needs to be turned over. The shawl 10 can be stably installed on the shoulder without turning the arm, which is convenient for wearing. Moreover, the indwelling tube does not obstruct the fit.

[0043] Example 2

[0044] Please see Figure 1 , 56, 8. This embodiment is a further optimization based on embodiment 1. Specifically, there are two heating devices 30, symmetrically arranged above the shawl 10. A control panel 31 is installed at the top of the heating device 30. The control panel 31 is equipped with a capacitive touch lock key, requiring the pressing of a specific combination of keys, such as pressing and holding the "+" key for 3 seconds, to activate the heating function, avoiding accidental operation by non-medical personnel. A player 34 is fixedly connected to the front of the heating device 30. A charging port 33 is installed on one side of the heating device 30. A heating module 35 is fixedly connected to the bottom of the heating device 30. The heating module 35 contains a heating wire, which is connected to... The lithium battery 38 is electrically connected, and the heating module 35 is attached to the shawl 10, using heat transfer to heat the shawl 10. A temperature sensor 36 is also fixedly connected to the bottom of the heating device 30. The temperature sensor 36 is an NTC thermistor with a measurement range of 0-50℃ and an accuracy of ±0.3℃. A pipe joint 37 is fixedly connected to the middle of the bottom of the heating device 30. The lithium battery 38 and the processor 39 are installed inside the heating device 30. The motor of the peristaltic pump mechanism 53, the control panel 31, the temperature sensor 36, and the player 34 are all electrically connected to the processor 39. The processor 39 has a built-in fuzzy logic controller, which dynamically adjusts the heating power according to the ambient temperature (fluctuation of ±2℃) and the patient's skin impedance value (monitored in real time through electrode pads) to maintain the target temperature error ≤±0.5℃. The processor 39 has a built-in Flash memory that can record 30 days of historical temperature curves and 100 operation logs (including timestamps and setting parameters). The lithium battery 38 is used to power the device, and an external power supply can also be provided via an electrical plug.

[0045] In this embodiment, the temperature sensor 36 measures the temperature of the shawl 10 and transmits the temperature to the processor 39. The processor 39 controls the heating module 35 to heat or pause heating. When the temperature exceeds the threshold, the temperature can also be manually set using the control panel 31. The player 34 is used to broadcast the temperature value. With this setting, the patient's shoulder can be heated and kept warm.

[0046] Example 3

[0047] Please see Figure 1 , 2 6, 7. This embodiment is a further optimization based on embodiment 1. Specifically, the top of the shawl 10 is fixedly connected to a connecting plug 15, and a slot 16 is provided in the middle of the connecting plug 15.

[0048] The heating device 30 is provided with a snap-fit ​​mechanism 40 at each of the four corners of its bottom. The snap-fit ​​mechanism 40 includes a slot 41 opened at the bottom of the heating device 30. A mounting groove 42 is opened on one side of the slot 41. An L-shaped operating rod 43 is provided inside the mounting groove 42. The top of the L-shaped operating rod 43 extends out of the surface of the heating device 30. The outer side of the end of the L-shaped operating rod 43 is fixedly connected to the mounting groove 42 by a spring 45. A locking block 44 is fixedly connected to the inner side of the end of the L-shaped operating rod 43. The locking block 44 extends into the slot 41. The connecting plug 15 is adapted to the slot 41, and the locking block 44 is adapted to the locking groove 16.

[0049] In this embodiment, by setting the connecting plug 15 and the slot 16, and with the cooperation of the snap-fit ​​mechanism 40, the heating device 30 is easy to assemble and disassemble. Since the shawl 10 is worn close to the body of critically ill patients, it is necessary to consider disposable use to avoid cross-infection. Therefore, this product sets the heating device 30 and the shawl 10 as two detachable parts, and sets the high-cost electronic components in the heating device 30 to reduce the cost of the shawl 10 as much as possible, thus greatly reducing medical costs.

[0050] Example 4

[0051] Please see Figure 2 , 3 6. 8. This embodiment is a further optimization based on embodiment 1. Specifically, the bottom of the shawl 10 is provided with a guide hole 12. There are multiple guide holes 12, which are arranged in a rectangular array. The diameter of the guide holes 12 is 2mm, and the hole spacing is 10mm×10mm. The inner wall of the guide hole 12 is provided with a micro-nano-level hydrophobic coating to prevent drug residue blockage. After 10 cycles of drug administration test, the flow rate attenuation rate is ≤5%. The top of the shawl 10 is equipped with a pipe interface 13, and the multiple guide holes 12 are connected to the pipe interface 13 through a conduit. The inner cavity of the heating device 30 is provided with a drug delivery mechanism 50. The drug delivery mechanism 50 includes a circular groove 51 opened in the inner cavity of the heating device 30 and a delivery mechanism 50 installed in the heating device 30. The internal medicine storage tank 54 has a drug delivery tube 52 fitted to the inner wall of the circular groove 51. A peristaltic pump mechanism 53 is provided in the middle of the drug delivery tube 52. One end of the drug delivery tube 52 is connected to the pipe connector 37, and the other end of the drug delivery tube 52 is connected to the medicine storage tank 54. The top of the medicine storage tank 54 is connected to the drug inlet pipe 55. The top of the drug inlet pipe 55 extends out of the heating device 30 and is equipped with a fixing cover 32. The pipe connector 37 is adapted to the pipe interface 13. The inner side of the fixing cover 32 is provided with internal thread, and the outer side of the drug inlet pipe 55 is provided with external thread. The two are connected in a threaded seal. The peristaltic pump mechanism 53 supports two driving modes: square wave and sine wave, which simulates the physiological rhythm of the human body (such as pulse drug delivery every 30 minutes) and improves the transdermal absorption rate of drugs.

[0052] In this embodiment, by setting numerous miniature drainage holes 12 on the shawl 10, and by setting a drug delivery mechanism 50 inside the heating device 30, the motor of the peristaltic pump mechanism 53 is controlled by the control panel 31. The peristaltic pump mechanism 53 delivers the drug inside the drug storage tank 54 to the pipe joint 37 through the drug delivery hose 52, and then to each drainage hole 12 through the pipe interface 13. The drug can be slowly released through the drainage holes 12 and act directly on the affected area of ​​the shoulder to achieve the effect of local treatment.

[0053] In summary, this invention, through the cooperative structure of the shawl 10 and the restraint strap 20, and the combination of female and male snap buttons, elastic bands and Velcro, allows for easy dressing without the need to move the patient's arm, significantly reducing the workload of medical staff and improving dressing efficiency. The restraint straps are symmetrically distributed at the bottom of the shawl, and the combination of Velcro and snap buttons ensures the stability of the shawl in the patient's shoulder position, preventing displacement or falling off due to movement. The insulation layer 11 is made of polyester cotton, which has both a soft touch and good heat insulation performance, effectively maintaining shoulder temperature and reducing patient discomfort.

[0054] The closed-loop control circuit integrating temperature sensor 36 and processor 39 monitors and adjusts the working status of heating module 35 in real time to achieve precise constant temperature, such as preset threshold alarm function to avoid the risk of low temperature burns; it supports dual modes of lithium battery power supply 38 and external power supply to adapt to different scenario needs, such as mobile power supply for ambulances; the control panel 31 allows medical staff to manually adjust temperature parameters, taking into account the flexibility of automation and manual intervention.

[0055] The mechanical interlock between the connecting plug 15 and the slot 16, combined with the spring-loaded snap-fit ​​snap-fit ​​44 of the snap-fit ​​mechanism 40, enables the quick assembly and disassembly of the heating device 30 and the shawl 10; high-cost electronic components are concentrated in the heating device 30, reducing the cost of disposable consumables; the separate design avoids the risk of cross-infection and meets the hospital infection control standards, in response to the disposable use requirements of medical scenarios.

[0056] The matrix layout of the 12 drainage holes ensures uniform drug diffusion, and the micro-flow control of the peristaltic pump mechanism 53, adjustable from 0.1 to 1 ml / min, ensures that the drug slowly penetrates into the shoulder lesion area; the independent sealing design of the drug storage box 54 prevents drug contamination or evaporation and extends the shelf life; the heat from the heating device 30 can promote local blood circulation and accelerate drug absorption efficiency; the dual functions of warmth preservation and local treatment are integrated, reducing additional treatment steps for patients and improving the overall nursing efficiency.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
