Description

Technical Field

[0001] This utility model relates to the field of postoperative recovery technology in cardiothoracic surgery, specifically to a minimally invasive incision protection device for cardiothoracic surgery. Background Technology

[0002] After undergoing minimally invasive cardiothoracic surgery, patients need to apply medication to the incision site and protect it by wrapping it with gauze.

[0003] Publication No. CN115429509A, Publication Date 20221206, discloses a postoperative incision protection device for thoracic surgery patients, including a cover, an installation groove provided on the lower side and inner side of the cover, a gauze layer provided on the inner side of the installation groove, a drug delivery layer provided on the lower side of the gauze layer, and a silicone pad provided on the lower side of the cover.

[0004] In the prior art, including the aforementioned patent, the incision is protected by a cover. However, ventilation is achieved by opening holes in the cover. Since the incision is covered with a drug delivery layer, even with the openings, the ventilation is not good, and external bacteria can easily enter the interior through the pores, leading to incision infection. Utility Model Content

[0005] The purpose of this invention is to provide a minimally invasive incision protection device for cardiothoracic surgery, which solves the technical problem that the existing technology has poor air permeability and that external bacteria can easily enter the interior through the pores, leading to incision infection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a minimally invasive incision protection device for cardiothoracic surgery, comprising:

[0007] A silicone ring is attached to the skin surface to fix the cotton for administering medication. The top of the ring has a protective shell that forms a sealed space with the skin surface to protect the incision. The top of the protective shell has an air cavity that communicates with the sealed space.

[0008] It also includes a cooling chamber with coolant inside and arranged in a circumferential array, and a cooling pipe with an air inlet and an air outlet communicating with the air chamber and the sealed space respectively. The air outlet of the cooling pipe is located at the bottom of the sealed space and faces the cotton wool.

[0009] The temperature inside the sealed space increases as the body temperature is transferred. The hot airflow converges at the top of the protective shell and enters the air cavity to adjust the air pressure at the bottom of the sealed space to a negative pressure. The hot airflow and coolant entering the air cavity are cooled by heat exchange through the cooling pipe to achieve internal circulation ventilation of the protective shell.

[0010] Preferably, the protective shell is an arc-shaped shell.

[0011] Preferably, the cooling pipe is arranged in a serpentine tubular shape.

[0012] Preferably, the system further includes a drying chamber connected between the cooling pipe outlet and the sealed space, wherein a desiccant is disposed.

[0013] Preferably, the cross-sectional area of ​​the air passage between the drying chamber and the sealed space gradually decreases from the air inlet to the air outlet, and a circular cavity is connected to the air outlet.

[0014] Preferably, the device also includes a heat exchange plate fixedly installed in the cooling chamber. The heat exchange plate has a first heat exchange column and a second heat exchange column arranged in an array on both sides. One end of the second heat exchange column penetrates the protective shell and contacts the outside air.

[0015] Preferably, one end of the second heat exchange column that penetrates the protective shell is fixedly connected to a cooling fin arranged in an arc shape.

[0016] In the above technical solution, the minimally invasive incision protection device for cardiothoracic surgery provided by this utility model has the following beneficial effects:

[0017] This invention utilizes a protective shell, cooling pipes, an air chamber, and a cooling cavity. The temperature within the sealed space increases with the transfer of body temperature. Hot air flows towards the top of the protective shell and enters the air chamber to regulate the air pressure at the bottom of the sealed space, creating a negative pressure. The cooling pipes exchange heat with the coolant entering the air chamber, thus ventilating and dissipating heat at the incision site. This effectively prevents skin ulceration due to poor ventilation. Simultaneously, the internal circulation ventilation effectively prevents bacterial infection of the wound from the external environment, significantly improving the protection of the incision. Furthermore, the device is small in size, low in manufacturing cost, and does not hinder the patient's movement. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, a minimally invasive incision protection device for cardiothoracic surgery includes:

[0028] A silicone ring 1 is attached to the skin surface to fix the cotton for administering medication. The top of the ring has a protective shell 2 that forms a sealed space with the skin surface to protect the incision. The top of the protective shell 2 has an air cavity 3 that communicates with the sealed space.

[0029] It also includes a cooling chamber 5 with coolant inside and arranged in a circumferential array, and a cooling pipe 6 with an air inlet and an air outlet that are respectively connected to the air chamber 3 and the sealed space. The air outlet of the cooling pipe 6 is located at the bottom of the sealed space and faces the cotton wool.

[0030] As the body temperature is transferred, the temperature inside the sealed space increases. The hot air flows towards the top of the protective shell 2 and enters the air cavity 3 to adjust the air pressure at the bottom of the sealed space to a negative pressure. The hot air and coolant entering the air cavity 3 are cooled by heat exchange through the cooling pipe 6 to achieve internal circulation ventilation of the protective shell 2.

[0031] Specifically, the cotton swab is attached to the groove at the bottom of the silicone ring 1, and the entire device is fixed to the patient's skin surface by the adhesive discs arranged in an array at the bottom of the silicone ring 1, so that the cotton swab covers the surface of the minimally invasive incision. The silicone ring 1 can better fit the patient's skin, thereby forming a sealed space inside the protective shell 2 to protect the minimally invasive incision.

[0032] Furthermore, the patient's own body temperature raises the temperature within the enclosed space, creating an upward-flowing hot airflow. This hot airflow converges at the top of the protective shell 2 and enters the air chamber 3 through vents at the top of the shell 2. This creates a negative pressure at the bottom of the enclosed space, allowing the hot airflow in the air chamber 3 to be drawn in through the cooling pipe 6. The hot airflow then exchanges heat with the coolant in the cooling chamber 5, cooling down before circulating back into the bottom of the enclosed space. This provides ventilation and heat dissipation for the incision, effectively preventing skin ulceration due to lack of ventilation. Simultaneously, the internal circulation ventilation effectively prevents bacterial infection of the wound from the external environment, significantly improving the protection of the incision. Moreover, the device is small in size, low in manufacturing cost, and does not hinder the patient's movement.

[0033] As a further embodiment of this utility model, the protective shell 2 is an arc-shaped shell.

[0034] Specifically, by setting the protective shell 2 as an arc-shaped shell, it is possible for hot air to gather at the top of the arc and smoothly enter the air chamber 3 through the air hole.

[0035] As a further embodiment of this utility model, the cooling pipe 6 is arranged in a serpentine tube shape.

[0036] Specifically, by setting the cooling pipe 6 as a serpentine pipe, the length of the cooling pipe 6 is increased, thereby enabling the hot airflow and cooling water to exchange heat fully and improving the heat exchange effect.

[0037] As a further embodiment of the present invention, it also includes a drying chamber 4 connected between the air outlet of the cooling pipe 6 and the sealed space, wherein a desiccant is disposed.

[0038] Specifically, the airflow that has been cooled by heat exchange through the cooling pipe 6 enters the drying chamber 4 for drying, thereby keeping the inside of the protective shell 2 dry and further preventing the growth of bacteria caused by a humid environment.

[0039] As a further embodiment of this utility model, the cross-sectional area of ​​the air passage between the drying chamber 4 and the sealed space gradually decreases from the air inlet to the air outlet, and a circular cavity is connected to the air outlet.

[0040] Specifically, since the cross-sectional area of ​​the air passage between the drying chamber 4 and the sealed space gradually decreases from the air inlet to the air outlet, the airflow that has been dried and cooled is accelerated through the air passage and sprayed into the circular cavity. Based on the principle that when the high-speed jet passes through the nozzle, the surrounding air is drawn into the jet to form a negative pressure area, the negative pressure effect can be improved, thereby forming a stable internal circulation.

[0041] As a further embodiment of the present invention, it also includes a heat exchange plate 7 fixedly disposed in the cooling cavity 5. The heat exchange plate 7 has a first heat exchange column 8 and a second heat exchange column 9 arranged in an array on both sides of its surface. One end of the second heat exchange column 9 penetrates the protective shell 2 and contacts the outside air.

[0042] Specifically, the second heat exchange column 9 can dissipate heat and cool the cooling water in the cooling chamber 5, while the first heat exchange column 8 can accelerate the heat exchange efficiency of the cooling water and make the heat exchange of the cooling water more uniform.

[0043] As a further embodiment of this utility model, a cooling fin 10 arranged in an arc shape is fixedly connected to one end of the second heat exchange column 9 that penetrates the protective shell 2.

[0044] Specifically, the heat exchange fins 10 can increase the contact area between the second heat exchange column 9 and the outside air, thereby further improving the heat exchange effect.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
