Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary storage equipment for ventricular assist devices, and in particular to a storage bag for ventricular assist devices. Background Technology

[0002] A ventricular assist device (VAD) is a medical device used to treat patients with heart failure. It helps the heart pump blood and maintain cardiac function. Patients using a VAD need to carry the device and related equipment to ensure proper treatment. However, because the blood pump and other components of a VAD require connection to an external power source, carrying the device is inconvenient and adds an extra burden to the patient.

[0003] Correspondingly, in the existing technology, the main equipment and related auxiliary equipment of the ventricular assist device are generally placed in a storage bag. The structure of this type of conventional storage bag is relatively simple and can meet the general use needs of patients.

[0004] However, the existing storage bags can only meet the basic storage needs of ventricular assist devices. When patients shower, the existing conventional storage bags are not effective at waterproofing, which allows water to enter the storage bag. This poses a risk of water ingress into the ventricular assist device located inside the storage bag, creating a safety hazard to the normal operation of the ventricular assist device.

[0005] Furthermore, patients need to frequently observe the ventricular assist device's display screen during daily use to understand its operational status and various monitoring parameters, allowing them to monitor their health in real time. However, the existing standard storage bags are all fully enclosed. Patients must completely open the bag to view the ventricular assist device's display screen inside. While this is not difficult in daily use, if the patient is showering, fully opening the bag exposes the ventricular assist device to the bathroom space. This exposes the device to direct contact with steam and splashing water, significantly impacting its stable operation and potentially causing serious harm to the patient, thus placing an additional burden on them.

[0006] In view of this, how to optimize the structure of the storage bag for ventricular assist devices so that it can provide reliable structural protection for the ventricular assist devices when the patient is showering, ensure the safe operation of the ventricular assist devices, and allow the patient to conveniently view the display screen of the ventricular assist devices while in the rain is an important technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a storage bag for a ventricular assist device (VAD), which can provide reliable structural protection for the VAD while the patient is showering, ensuring the safe operation of the VAD and allowing the patient to conveniently view the VAD's display screen even while in the rain.

[0008] To solve the above-mentioned technical problems, this utility model provides a ventricular assist device storage bag, including a main bag body and an outer protective cover that is fastened to the top of the main bag body from top to bottom. The main bag body has a storage cavity inside that can accommodate the ventricular assist device.

[0009] The main package includes a package body and a cover that is detachably mounted on the top of the package body. The package body and the cover are appropriately matched and aligned to form the storage cavity and isolate the storage cavity from the external environment. The middle part of the cover has an inner observation hole that is aligned with the display screen of the ventricular assist device.

[0010] The outer protective cover is fitted over the outside of the bag cover from top to bottom, and the bottom edge of the side wall of the outer protective cover is lower than the top edge of the side wall of the bag body. The middle part of the outer protective cover has an outer observation hole that aligns with the inner observation hole. The inner observation hole and the outer observation hole are respectively encapsulated with transparent baffles.

[0011] Both the main package and the outer protective cover are multi-layered structural components, and the outermost layer of the main package and the outermost layer of the outer protective cover are waterproof Oxford cloth protective layers.

[0012] Preferably, the ventricular assist device storage bag also includes a shoulder strap, and two loops are provided on the outer wall of the bag body. The two loops are symmetrically arranged on both sides of the bag body. Each end of the shoulder strap is provided with a hook, and the hooks are detached and fitted to the loops in a one-to-one correspondence.

[0013] Preferably, the bottom edge of the side wall of the outer protective cover is recessed with two buckle notches, and the two buckle notches are symmetrically arranged on both sides of the outer protective cover;

[0014] The buckle notch is aligned and adapted to the hanging ear so that the hanging ear is located in the buckle notch in a one-to-one correspondence when the outer cover is fastened to the main body.

[0015] Preferably, the cross-section of the main bag body and the cross-section of the outer protective cover are both rectangular, the two hanging ears are symmetrically arranged on the side walls corresponding to the two short sides of the cross-section of the main bag body, and the two buckle notches are symmetrically arranged on the side walls corresponding to the two short sides of the cross-section of the outer protective cover.

[0016] Preferably, the bottom edge of the sidewall corresponding to one of the long sides of the cross-section of the outer protective cover is hinged to the sidewall corresponding to one of the long sides of the cross-section of the main body;

[0017] The sidewall corresponding to the other long side of the cross-section of the outer protective cover is detachably and adaptably connected to the sidewall corresponding to the other long side of the cross-section of the main body via Velcro.

[0018] Preferably, a storage bag for accommodating the main equipment of the ventricular assist device is fixed in the middle of the inner wall of the cover, and the opening of the storage bag is attached to the inner wall of the cover by Velcro.

[0019] Preferably, a plurality of reciprocating drawstrings are connected between the outer wall of the storage bag and the inner wall of the bag flap. One end of the drawstring is fixed to the inner wall of the bag flap, and the other end of the drawstring is connected to the outer wall of the storage bag by snaps and can be detached and adapted.

[0020] Preferably, the inner layer of the main package is a pearl cotton cushioning layer, and the outer wall of the pearl cotton cushioning layer is tightly fitted to the inner wall of the waterproof Oxford cloth protective layer.

[0021] Preferably, the interior of the pearl cotton cushioning layer is embedded with an aluminum foil waterproof layer.

[0022] Preferably, the transparent baffle is made of PET material.

[0023] Compared with the above-mentioned background technology, the ventricular assist device storage bag provided by this utility model allows the ventricular assist device to be placed in the storage cavity during operation and use. Then, the bag body and bag cover can be fastened together to close the storage cavity. Then, the outer cover is fastened to the top of the main bag body from top to bottom, so that the outer cover forms an assembly form that is fitted on the upper part of the main bag body. After the outer cover is assembled with the main body, the bottom of each side wall of the outer cover will be lower than the top of each side wall of the main body. That is, the lower edge of the outer cover will be below the mating surface of the main body and the cover. In this way, the entire cover is located in the inner cavity of the outer cover, and the upper part of the main body structure is also located in the inner cavity of the outer cover. Thus, the outer cover provides full coverage and protection for the upper structure of the main body. In particular, the outer cover can fully shield and protect the alignment and joint of the main body and the cover, preventing water or other liquids from the external environment from entering the storage cavity through the joint of the main body and the cover. This avoids the adverse effects of water ingress on the ventricular assist device located in the storage cavity, ensuring the stable operation of the ventricular assist device. Accordingly, the waterproof Oxford cloth sheath provides basic waterproofing for the main body and outer cover, preventing water or other liquids from the external environment from seeping into their main structure, thus further preventing water from entering the storage cavity and the ventricular assist device (VAD) inside. Simultaneously, patients can directly view the data displayed on the VAD's screen within the storage cavity through the aligned external and internal observation ports, allowing them to monitor the VAD's operational status and related parameters in real time. Correspondingly, the transparent baffle effectively blocks water or other liquids from the external environment from entering the storage cavity through the external and internal observation ports, making the waterproofing of the main structure of the VAD storage bag more comprehensive and sufficient. This makes the structural protection of the VAD more reliable, and the operation of the VAD within the storage cavity more stable and safe.

[0024] In another preferred embodiment of this utility model, the ventricular assist device (VAD) carrying bag further includes a shoulder strap. Two loops are provided on the outer wall of the bag body, symmetrically arranged on both sides of the bag body. Each end of the shoulder strap has a hook, which is detachable and compatible with the loops. In daily use, the shoulder strap can be used to attach or wear the VAD carrying bag across the patient's body, allowing for convenient carrying of the bag and the VAD device inside, thus optimizing the ease of use of the VAD device. When the patient is showering or otherwise needs to remove the VAD device from their body, the shoulder strap can be attached to a clothes hanger or other support to suspend the main structure of the VAD carrying bag, thereby ensuring the structural balance of the main body and the outer cover. This ensures the stable placement of the VAD device within the storage cavity, guaranteeing its safe and reliable operation. Attached Figure Description

[0047] Please refer to the reference. Figure 1 , Figure 3 and Figure 4 .

[0048] In a specific embodiment, the ventricular assist device storage bag provided by this utility model includes a main bag body 10 and an outer protective cover 20 that is fastened to the top of the main bag body 10 from top to bottom. The main bag body 10 has a storage cavity 101 inside that can accommodate the ventricular assist device.

[0049] The main body 10 includes a body 11 and a cover 12 that is detachably mounted on the top of the body 11. The body 11 and the cover 12 are properly fitted together and are aligned and fastened together to form a storage cavity 101 and isolate the storage cavity 101 from the external environment. The middle part of the cover 12 has an inner observation hole 121 that is aligned and fitted with the display screen of the ventricular assist device.

[0050] The outer cover 20 is fitted over the outside of the cover 12 from top to bottom, and the bottom edge of the side wall of the outer cover 20 is lower than the top edge of the side wall of the body 11. The middle part of the outer cover 20 has an outer observation hole 201 that aligns with the inner observation hole 121. A transparent baffle 21 is encapsulated on the inner observation hole 121 and the outer observation hole 201 respectively.

[0051] Both the main body 10 and the outer cover 20 are multi-layered structural components, and the outermost layer of the main body 10 and the outermost layer of the outer cover 20 are waterproof Oxford cloth protective layers.

[0052] In actual operation, the ventricular assist device is placed in the receiving cavity 101. Then, the body 11 and the cover 12 are fastened together to close the receiving cavity 101. Next, the outer cover 20 is fastened from top to bottom onto the top of the main body 10, so that the outer cover 20 is fitted onto the upper part of the main body 10. After the outer cover 20 and the main body 10 are assembled, the bottom of each side wall of the outer cover 20 will be lower than the top of each side wall of the body 11. That is, the lower edge of the outer cover 20 will be below the mating surface of the body 11 and the cover 12. Thus, the cover 12 is entirely inside the cavity of the outer cover 20, and the upper part of the main structure of the body 11 is also inside the cavity of the outer cover 20.

[0053] Thus, the outer cover 20 provides sufficient coverage and protection for the upper structure of the main body 10. In particular, the outer cover 20 effectively shields and protects the alignment and joint of the body 11 and the cover 12, preventing water or other liquids from the external environment from entering the storage cavity 101 through the joint of the body 11 and the cover 12. This avoids the adverse effects of water ingress on the ventricular assist device located in the storage cavity 101, ensuring the stable operation of the ventricular assist device.

[0054] Accordingly, the waterproof Oxford cloth sheath provides basic waterproof performance for the main body 10 and the outer cover 20, preventing water or other liquids from the external environment from penetrating into the main structure of the main body 10 and the outer cover 20, thereby further preventing water from entering the housing 101 and the ventricular assist device inside.

[0055] Meanwhile, patients can directly view the data displayed on the screen of the ventricular assist device inside the storage cavity 101 through the aligned external observation port 201 and internal observation port 121, so as to understand the working status and related monitoring and operating parameters of the ventricular assist device in real time. Correspondingly, the transparent baffle 21 can effectively prevent water or other liquids in the external environment from entering the storage cavity 101 through the external observation port 201 and internal observation port 121, thereby making the waterproof performance of the main structure of the ventricular assist device storage bag more comprehensive and sufficient. This makes the structural protection of the ventricular assist device by the storage bag more reliable, and the operation of the ventricular assist device located in the storage cavity 101 more stable and safe.

[0056] It is easy to understand that, in practical applications, the bag body 11 and the bag flap 12 can be closed or opened by means of a zipper assembly 13 as shown in the figure. The zipper part of the zipper assembly 13 extends along the fitting surfaces of the bag body 11 and the bag flap 12 and connects end to end. The zipper assembly 13 is preferably equipped with symmetrically arranged double zipper heads 131 so as to form a gap 132 between the two zipper heads 131 for the relevant cables of the ventricular assist device to pass through. The gap 132 can be adjusted accordingly as the position of the two zipper heads 131 is adjusted, thereby further optimizing the ease of use of the ventricular assist device.

[0057] Of course, Velcro or snaps can also be used to connect the bag body 11 and the flap 12 for alignment and fastening, or for disassembly and folding. However, it should be ensured that the corresponding Velcro or snaps can extend and distribute along the mating surfaces of the bag body 11 and the flap 12 to ensure reliable closure of all parts of the mating surfaces between the bag body 11 and the flap 12. It is not difficult to see that, considering the actual working conditions and specific application effects, it is still advisable to use the zipper assembly 13 shown in the figure to achieve the alignment, fastening, closure, disassembly, and folding of the bag body 11 and the flap 12 in this solution.

[0058] Please refer to this carefully. Figure 2 Specifically, the ventricular assist device (VAP) carrying case also includes a shoulder strap 30. Two loops 14 are symmetrically arranged on both sides of the case body 11 on the outer wall. Each end of the shoulder strap 30 has a hook 31, which is attached and detached from the loops 14 in a corresponding manner. In daily use, the shoulder strap 30 can be used to strap or wear the VAP carrying case across the patient's body, allowing the patient to conveniently carry the case and the VAP device inside, thereby optimizing the ease of use of the VAP device.

[0059] Accordingly, when the patient is showering or otherwise needs to remove the ventricular assist device from their body, the shoulder strap 30 can be attached to a clothes hanger or other support to suspend the main structure of the ventricular assist device storage bag, thereby ensuring the structural balance of the main bag body 10 and the outer protective cover 20, so that the ventricular assist device located in the storage cavity 101 remains stable, thus ensuring the safe and reliable operation of the ventricular assist device.

[0060] Generally, a shoulder pad 32 is placed in the middle of the shoulder strap 30. The shoulder pad 32 is usually made of an outer layer of waterproof Oxford cloth or other waterproof fabric, combined with a soft and waterproof filling such as pearl cotton inside, to provide appropriate cushioning for the patient when carrying the ventricular assist device carrying bag, and to prevent the shoulder strap 30 from pressing on the patient's shoulder and causing pain.

[0061] Correspondingly, at least one adjustment buckle 301 will be arranged on the shoulder strap 30 to adjust the effective length of the shoulder strap 30 to match the carrying needs of patients of different sizes. Of course, the specific structure of the adjustment buckle 301 and its adjustment principle for the shoulder strap 30 can be directly understood by referring to the operation method of the adjustment buckle 301 of the backpack strap in the prior art. This solution does not make any revolutionary changes to the technical details here, so it will not be described in detail.

[0062] More specifically, the bottom edge of the side wall of the outer cover 20 has two recessed snap-fit ​​notches 202, which are symmetrically arranged on both sides of the outer cover 20. The snap-fit ​​notches 202 are aligned and fitted with the ear loops 14 so that the ear loops 14 are located in the snap-fit ​​notches 202 one by one when the outer cover 20 is fastened to the main body 10. After the outer cover 20 is aligned and fastened to the main body 10, the two snap-fit ​​notches 202 can form sufficient accommodating space to align and fit with the ear loops 14 one by one. This not only avoids structural interference or jamming between the main structure of the outer cover 20 and the ear loops 14, but also provides appropriate shielding and structural protection for the ear loops 14 by utilizing the main structure of the outer cover 20 above the snap-fit ​​notches 202. This prevents water droplets generated during the patient's shower from splashing onto the ear loops 14 and causing problems such as corrosion or blockage, ensuring the smooth use of the ear loops 14.

[0063] Based on this, the cross-sections of the main body 10 and the outer cover 20 are both rectangular. Two hooks 14 are symmetrically arranged on the sidewalls corresponding to the two short sides of the cross-section of the main body 10, and two buckle notches 202 are symmetrically arranged on the sidewalls corresponding to the two short sides of the cross-section of the outer cover 20. Thus, when the ventricular assist device storage bag is carried by the patient as a whole or suspended, the hooks 14, in conjunction with the shoulder strap 30, can form a bilaterally balanced suspension point, allowing the main body 10 to easily maintain balance. This ensures that the ventricular assist device located within the storage cavity 101 remains stably positioned, thereby guaranteeing reliable support and stable operation of the ventricular assist device, and further ensuring its safe use.

[0064] It is easy to understand that the cross section mentioned above refers to the cross section taken along the horizontal extension direction when the ventricular assist device storage bag is placed normally. The cross section terminology used in other parts of this article can be understood in the same way as here, and will not be repeated here.

[0065] Accordingly, the bottom edge of the sidewall corresponding to one long side of the cross-section of the outer cover 20 is hinged to the sidewall corresponding to one long side of the cross-section of the main body 10; the sidewall corresponding to the other long side of the cross-section of the outer cover 20 is detachably and adaptably connected to the sidewall corresponding to the other long side of the cross-section of the main body 10 via Velcro 15. This allows the outer cover 20 to form a flipping structure based on one long side of its bottom edge as an axis, thereby increasing the effective range of the hinged connection between the outer cover 20 and the main body 10, improving the assembly strength between the outer cover 20 and the main body 10, and enhancing the structural support effect of the outer cover 20. This makes the overall structure of the ventricular assist device storage bag more reliable.

[0066] On the other hand, a storage bag 122 for accommodating the main device of the ventricular assist device is fixed to the middle of the inner wall of the cover 12. The opening of the storage bag 122 is attached to the inner wall of the cover 12 via Velcro. The main device of the ventricular assist device is reliably placed inside the storage bag 122. The compact structure of the storage bag 122 further improves the stability of the main device within the storage cavity 101, preventing significant shaking and impact that could damage the main device. The Velcro allows for flexible control of the opening and closing of the storage bag 122, facilitating the insertion and removal of the main device.

[0067] It should be noted that when the main device of the ventricular assist device is placed in the storage bag 122, the remaining space in the storage cavity 101 other than the storage bag 122 can be used to store other supporting equipment and cables of the ventricular assist device, so as to realize the centralized storage of related accessories of the ventricular assist device, thereby making full use of the internal space of the storage cavity 101, making the internal storage space of the ventricular assist device storage bag more compact and orderly, and the storage space utilization rate is higher.

[0068] Furthermore, a plurality of reciprocating and extendable drawstrings 123 are connected between the outer wall of the storage bag 122 and the inner wall of the cover 12. One end of each drawstring 123 is fixed to the inner wall of the cover 12, and the other end of each drawstring 123 is connected to the outer wall of the storage bag 122 by snaps and can be detached and fitted together. The drawstrings 123 are typically made of high-elastic fabric, rubber, silicone, or other materials with a certain degree of elasticity, so that the elasticity of the drawstrings 123 can be used to reliably tighten the storage bag 122, thereby fully clamping the main device of the ventricular assist device located inside the storage bag 122, so as to further prevent the main device of the ventricular assist device from shaking, misaligning, or even loosening inside the storage bag 122, and ensure that the storage bag 122 safely and stably stores the main device of the ventricular assist device.

[0069] In addition, the inner layer of the main body 10 is a pearl cotton cushioning layer, and the outer wall of the pearl cotton cushioning layer is tightly bonded to the inner wall of the waterproof Oxford cloth protective layer. Pearl cotton, also known as polyethylene foam (EPE), has good water-proof, shock-proof and heat-insulating properties, which can fully ensure the cushioning, shock absorption and structural protection of the ventricular assist device located in the receiving cavity 101 by the main body 10.

[0070] Building upon this, an aluminum foil waterproof layer is embedded within the pearl cotton cushioning layer. This aluminum foil waterproof layer further optimizes the waterproof and water-resistant performance of the main package 10. Especially considering current technology choices in the field of composite materials, the combination of pearl cotton with fabrics such as Oxford cloth and aluminum foil significantly enhances the overall structural strength and UV protection, thereby greatly improving the operational tolerance of the main package 10. This makes the main structure of the ventricular assist device storage bag more durable.

[0071] In addition, the transparent baffle 21 is made of PET (polyethylene terephthalate). This PET material is colorless and transparent, possessing good transmittance and mechanical properties, as well as good high and low temperature resistance, and good resistance to oils and common solvents. The plate made of this PET material serves as a sealing and shielding element for the external observation holes 201 and the internal observation holes 121. This not only ensures smooth and clear observation of the ventricular assist device's display screen inside the receiving cavity 101 by the patient, but also significantly improves the working condition tolerance of the transparent baffle 21 by utilizing its own good tolerance, making the transparent baffle 21 more durable.

[0072] Generally, the transparent baffle 21 can be a rigid plate or a relatively soft plate. Correspondingly, the edge of the transparent baffle 21 at the inner observation hole 121 can be glued or sewn to the main structure of the cover 12, while the edge of the transparent baffle 21 at the outer observation hole 201 can be glued or sewn to the main structure of the outer protective cover 20. In practical applications, operators can flexibly select and adjust the specific installation form of the transparent baffle 21 according to specific working conditions and processing conditions. In principle, as long as reliable sealing of the outer observation hole 201 and the inner observation hole 121 can be guaranteed, and the patient can directly observe the display screen of the ventricular assist device inside the receiving cavity 101 through the outer observation hole 201 and the inner observation hole 121, it is acceptable.

[0073] In summary, the ventricular assist device storage bag provided in this utility model allows the ventricular assist device to be placed in the storage cavity during operation. Then, the bag body and the bag cover can be fastened together to close the storage cavity. Finally, the outer cover is fastened to the top of the main bag body from top to bottom, so that the outer cover is assembled in the form of a sleeve on the upper part of the main bag body. After the outer cover is assembled with the main body, the bottom of each side wall of the outer cover will be lower than the top of each side wall of the main body. That is, the lower edge of the outer cover will be below the mating surface of the main body and the cover. In this way, the entire cover is located in the inner cavity of the outer cover, and the upper part of the main body structure is also located in the inner cavity of the outer cover. Thus, the outer cover provides full coverage and protection for the upper structure of the main body. In particular, the outer cover can fully shield and protect the alignment and joint of the main body and the cover, preventing water or other liquids from the external environment from entering the storage cavity through the joint of the main body and the cover. This avoids the adverse effects of water ingress on the ventricular assist device located in the storage cavity, ensuring the stable operation of the ventricular assist device. Accordingly, the waterproof Oxford cloth sheath provides basic waterproofing for the main body and outer cover, preventing water or other liquids from the external environment from seeping into their main structure, thus further preventing water from entering the storage cavity and the ventricular assist device (VAD) inside. Simultaneously, patients can directly view the data displayed on the VAD's screen within the storage cavity through the aligned external and internal observation ports, allowing them to monitor the VAD's operational status and related parameters in real time. Correspondingly, the transparent baffle effectively blocks water or other liquids from the external environment from entering the storage cavity through the external and internal observation ports, making the waterproofing of the main structure of the VAD storage bag more comprehensive and sufficient. This makes the structural protection of the VAD more reliable, and the operation of the VAD within the storage cavity more stable and safe.

[0074] The ventricular assist device storage bag provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
