[0031] The technical solutions 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 only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-4 The present invention discloses an artificial heart protection device, comprising:

[0033] A waterproof cover 1 is used to cover the cable film. The waterproof cover 1 has an arc groove and a threading hole for the artificial heart cable to pass through on the side in contact with the human body. The threading hole is connected to the arc groove.

[0034] The sealing mechanism 2 is arranged at the threading hole of the waterproof cover 1, and is used to seal the artificial heart cable and connect the two ends of the arc groove after the artificial heart cable is moved into the threading hole, thereby forming a complete annular air chamber in cooperation with the waterproof cover 1;

[0035] The injection and exhaust mechanism 3 is arranged on the waterproof cover 1, one end of which is connected to the annular air chamber and is used for exhausting the gas inside the annular air chamber and injecting gas into the annular air chamber.

[0036] The present invention arranges the waterproof cover 1 on the cable film, and after the artificial heart cable passes through the threading hole, the artificial heart cable is sealed by the sealing mechanism 2, and then the air in the annular air chamber is extracted by the injection and exhaust mechanism 3. Because the waterproof cover 1 is in close contact with the skin, a negative pressure environment is formed in the annular air chamber, and the waterproof cover 1 is fixed to the skin surface by the external air pressure. After that, the patient can perform the cleaning operation. Due to the obstruction of the waterproof cover 1, the liquid during cleaning will not enter the area where the cable film is located, thereby achieving the purpose of protecting the wound and avoiding water.

[0037] It should be noted that after the use of the waterproof cover 1, it is only necessary to inject air into the annular air chamber through the exhaust mechanism 3 to release the adsorption of the waterproof cover 1 on the human body. After that, it is only necessary to release the seal of the artificial heart cable by the sealing mechanism 2 to remove the waterproof cover 1, which will not affect the air permeability of the area where the cable film is located when the patient's normal life is not affected.

[0038] In one embodiment, the sealing mechanism 2 includes a first sealing plate 21 and a second sealing plate 22 which are arranged on the waterproof cover 1 and can slide toward and away from one side of the artificial heart cable. The first sealing plate 21 and the second sealing plate 22 are respectively located at both ends of the arc-shaped groove. A connecting groove is provided on the side of the second sealing plate 22 in contact with the human body, and one end of the connecting groove is connected with the arc-shaped groove. When the second sealing plate 22 abuts against the artificial heart cable, the second sealing plate 22 is inserted into the other end of the arc-shaped groove, so that the connecting groove and the arc-shaped groove form a complete annular air chamber.

[0039] The first sealing plate 21 is provided with a locking assembly 23 for locking the second sealing plate 22 , and is used to limit the movement of the first sealing plate 21 and the second sealing plate 22 when both the first sealing plate 21 and the second sealing plate 22 abut against the artificial heart cable.

[0040] Such a design ensures that when the first sealing plate 21 and the second sealing plate 22 move away from the artificial heart cable, the normal entry and exit of the artificial heart cable in and out of the threading hole area will not be affected. After the first sealing plate 21 and the second sealing plate 22 move toward the artificial heart cable and abut against the artificial heart cable, the first sealing plate 21, the second sealing plate 22 cooperates with the waterproof cover 1 to tightly wrap the artificial heart cable. After the position is locked by the locking assembly 23, moisture during cleaning can be prevented from entering the interior of the waterproof cover 1 from the artificial heart cable. At the same time, because the connecting groove and the arc groove form a complete annular air chamber when the second sealing plate 22 abuts against the artificial heart cable, the annular air chamber can be evenly adsorbed on the skin surface after being exhausted, thereby preventing surrounding cleaning moisture from entering.

[0041] It should be noted that dynamic sealing components are provided between the first sealing plate 21 and the waterproof cover 1, between the second sealing plate 22 and the waterproof cover 1, and between the first sealing plate 21 and the second sealing plate 22 to ensure the sealing after the first sealing plate 21 and the second sealing plate 22 move. The dynamic sealing components belong to mature existing technologies and will not be elaborated on here.

[0042] In a specific implementation, the locking assembly 23 is preferably a spring latch, and a slot corresponding to the spring latch is opened on the side of the second sealing plate 22 close to the first sealing plate 21. When the first sealing plate 21 and the second sealing plate 22 are both in contact with the artificial heart cable, the spring latch is inserted into the slot. When it is necessary to unlock the second sealing plate 22, it is only necessary to push the spring latch to move the spring latch out of the slot, so that the entire locking and unlocking operation is quick and convenient.

[0043] In one embodiment, the end of the injection and exhaust mechanism 3 away from the waterproof cover 1 is provided with a one-way exhaust component 31 for exhausting the gas in the annular air chamber and a gas injection component 32 for injecting external gas into the annular air chamber.

[0044] This design ensures that the exhaust gas and the injection gas of the injection and exhaust mechanism 3 do not interfere with each other, thereby reducing the risk of misoperation.

[0045] In one embodiment, the one-way exhaust assembly 31 includes a one-way valve and an exhaust pipe connecting the one-way valve and the annular air chamber. The one-way valve is used to prevent external gas from flowing to one side of the exhaust pipe through the one-way valve.

[0046] Such a design allows the user to directly connect the one-way valve through the disposable syringe and extract the air in the annular air chamber by pulling the disposable syringe, which has low use cost and will not cause air backflow.

[0047] In one embodiment, the gas injection assembly 32 includes a gas injection pipe disposed on the waterproof cover 1 and connected to the annular air chamber. A sealing cap is detachably provided at one end of the gas injection pipe away from the waterproof cover 1 for changing the connection state between the gas injection pipe and the external environment.

[0048] With this design, when the one-way exhaust component 31 is sucking, the air injection pipe is blocked by the sealing cap to prevent external air from entering. When air needs to be injected, the sealing cap only needs to be loosened, and external air can enter the annular air chamber under the action of negative pressure, thereby releasing the adsorption of the waterproof cover 1 on the human body.

[0049] A nursing bag contains any one of the artificial heart protection devices.

[0050] In one embodiment, the nursing package further contains:

[0051] Cable film, with a 1cm threading hole in the center and a 3*3cm sterile dressing around the hole, used for the skin cable outlet, replacing the original cable film;

[0052] A fixing strap for fixing the artificial heart cable to the cable film and the human body;

[0053] Y-shaped gauze is used between the cable film and the skin to prevent the cable from pressing on the surrounding skin for a long time and causing damage;

[0054] Cotton balls, used to clean artificial heart cables and human skin when replacing cable films;

[0055] Sterile gloves for caregivers to wear when replacing cable films.

[0056] This design concentrates the nursing appliances required by the patient in one nursing package, thus solving the patient's various needs at one time and reducing the inconvenience caused by the patient purchasing them separately.

[0057] It should be noted that the waterproof cover 1 can be made of plastic and can be discarded after use, thereby reducing the risk of infection due to repeated use.

[0058] Preferably, the fixing belt is 8 cm long and 2 cm wide.

[0059] In another embodiment, the waterproof cover 1 can be made of metal material, purchased separately from the nursing package, and can be reused, thereby reducing the cost of use for patients.

[0060] In one embodiment, a waterproof bag is also installed inside the nursing bag, which can be detachably arranged at the battery-powered device connected to the artificial heart cable to provide waterproof protection for the battery-powered device, thereby further improving the convenience of cleaning for the patient.

[0061] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0063] In addition, "plurality" means two or more.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
