Description

Cooling helmet

[0001] The present invention relates to a cooling helmet, and more specifically, to a device that does not have separate mechanical or electrical mechanism parts and thus does not generate vibrations when operated, is lightweight, reduces headaches caused by high fever in the head of a patient with a brain disease, and facilitates hypothermia treatment on the patient's head, can prevent and treat side effects of hair loss caused by cancer treatment and non-hereditary thermal alopecia caused by high fever in the head, and can be used when head cooling is required in various sports.

[0002] In general, hypothermia is a promising neuroprotective therapy for improving outcomes in patients with neurological injuries, including heart attack, neonatal asphyxiation, stroke, head trauma, and seizures.

[0003] Conventionally, only ice packs, cooling tents, fluid pads, cooling blankets, cooling water circulation helmets, and liquid coolant sprays in the nasal cavity have been proposed to induce hypothermia, so the development of more effective cooling devices is required.

[0004] For example, Korean Patent No. 10-2358138 discloses a cooling helmet including a helmet body worn on the head to prepare for impact, including an outer shell having impact strength in a form that surrounds the wearer's head and a shock absorber that adheres closely to the inner surface of the outer shell to reduce impact; and a cooling device that induces the inflow of outside air into the helmet body and cools the inflowing gas while being mounted at a predetermined position of the helmet body, thereby lowering the internal temperature of the helmet body.

[0005] However, the cooling device described above is configured with a cooling module that cools the inflow gas and causes the gas to move, and a control unit that operates the cooling module when power is supplied while being provided in the main body, and an intake duct that is hinged to enable direction adjustment for controlling the amount of external air being introduced, and thus has a problem in that it is unsuitable for use by patients requiring treatment using hypothermia.

[0006] In addition, Korean Patent Publication No. 10-2017-0110379 discloses a helmet having a thermoelectric element, including an outer shell located at the outermost portion; a liner located on the inside of the outer shell to absorb shock; an air inlet formed in the outer shell; a thermoelectric element located between the outer shell and the liner; and a control unit that controls the operation of the thermoelectric element through a plurality of sensors.

[0007] However, according to the above-mentioned prior art documents, vibration is inevitable when the control unit, liner, thermoelectric element, etc. are operated, and the voltage applied to the thermoelectric element to implement the cooling function when the device is operated by a battery is high, which can be dangerous, and the instantaneous power consumption of the battery is very high, so the efficiency compared to the input can be greatly reduced, and since a device such as a fan for forced cooling must be installed, the weight of the helmet is bound to increase, so there were problems in that the convenience, efficiency, and duration of use can be significantly reduced.

[0008]

[0009] In order to solve such problems, the present invention has been devised based on the aforementioned background technology, and its purpose is to provide a cooling helmet that is lightweight because it does not have mechanical or electrical mechanical parts, and does not generate vibrations when operated, so that users, including patients with brain diseases, can use it more safely.

[0010] In addition, the present invention aims to provide a cooling helmet that can alleviate headaches caused by high fever in the head of a patient with a brain disease, thereby facilitating hypothermia treatment for the patient's head.

[0011] In addition, the present invention aims to provide a cooling helmet that prevents hair loss caused by side effects of anticancer treatment and non-hereditary recessive hair loss caused by high fever in the scalp, thereby enabling appearance management no different from that of a normal person.

[0012] Furthermore, the present invention aims to provide a cooling helmet that can be worn on the head to regulate scalp temperature, reduce excitement, and provide a calming effect when symptoms such as heatstroke, headache, dizziness, and lethargy occur due to heat in the head during ordinary daily life or various sports, and can be used when cooling the head is necessary.

[0013] In addition, the present invention aims to provide a cooling helmet that is manufactured using eco-friendly materials, making it harmless to the human body and easy for anyone to use due to its simple assembly and disassembly.

[0014] In addition, the present invention aims to provide a cooling helmet that is lightweight and portable, and has an assembly structure that allows for the attachment and detachment of only the refrigerant, thereby minimizing inconvenience during use.

[0015] Furthermore, the present invention aims to provide a cooling helmet that is a passive, zero-energy invention in which a PCM refrigerant is applied to the cooling body, thereby enabling the acquisition of carbon credits through substantial greenhouse gas reduction and participation in campaigns such as RE100 during future business development, and thus providing eco-friendliness.

[0046]

[0047] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0048] As illustrated, the cooling helmet of the present invention is formed in a form that wraps around the head of a user including a patient, and is configured to include a helmet body part (100) that protects the head of the user from external impact, a cooling body part (200) that is detachably coupled to the helmet body part (100) and has a refrigerant filled and injected therein, a cooling pad part (300) that provides a space between the head (or scalp) of the user and the cooling body part (200) to prevent direct contact between the cooling body part (200) and the user's head and to allow the refrigerant (or cold air) emitted from the cooling body part (200) to be smoothly transferred to the user's head, and a locking unit (400) that supports the cooling body part (200) so that it can be detachably coupled to the helmet body part (100).

[0049] The helmet body (100) is formed with an open bottom, and a receiving portion (110) is formed to receive the cooling body (200) and the cooling pad portion (300), into which they can be inserted so that they can be detachably combined.

[0050] The receiving portion (110) is formed as an inner surface of the helmet body (100), and is formed with a shape corresponding to the upper surface of the cooling pad portion (300), i.e., the surface of the cooling pad portion (300), and is configured to support the cooling pad portion (300) so that it can be inserted into the body in a close manner, and a second receiving portion (114) is formed with a groove shape in the central portion of the first receiving portion (112), but is formed with a shape corresponding to the upper surface of the cooling body portion (200), and is configured to support the cooling body portion (200) so that it can be inserted into the body in a close manner.

[0051] In addition, the helmet body (100) is configured in a second receiving portion (114), and a first anti-sagging protrusion (120) is formed to protrude from the front and rear portions of the second receiving portion (114), and is inserted into the anti-sagging portion (220) of the cooling body portion (200) to be described later.

[0052] The first sagging prevention protrusion (120) prevents the bulging phenomenon due to volume change during cooling of the refrigerant main body (200) and prevents the sagging phenomenon of the internal space, i.e., the refrigerant charging section (202).

[0053] This first anti-sagging projection (120) is located on the same axis as the anti-sagging portion (220) of the cooling body part (200), more preferably the upper anti-sagging portion (222) of the anti-sagging portion (220), and is configured to be inserted into the upper anti-sagging portion (222) and closely adhere to the bottom surface of the upper anti-sagging portion (222) when the cooling body part (200) is coupled to the helmet body part (100).

[0054] In addition, the helmet body (100) is configured on each of the lower two sides, and a first locking support (130) is configured to support the first locking unit (410) of the locking unit (400) so that it can be rotatably coupled.

[0055] The first locking support (130) serves to fix the cooling pad portion (300) to the helmet body portion (100) by the rotational operation of the first locking unit (410) or to support the cooling pad portion (300) so that it can be separated from the helmet body portion (100).

[0056] This first locking support member (130) is configured to include a side locking guide groove (132) into which the first locking unit (410) is rotatably inserted, a rotational support member (134) formed to protrude from the center of the side locking guide groove (132) and supporting the rotational operation of the first locking unit (410), and a fixing groove (136) formed at the end of the side locking guide groove (132) into which the fixing projection (416) of the first locking unit (410) is detachably inserted.

[0057] Here, the rotation support (134) is configured so that the rotation shaft (412) of the first locking unit (410) is inserted and penetrated therein, so that the first locking unit (410) can be rotatably coupled to the first locking support (130).

[0058] Additionally, the fixing groove (136) is formed in a shape corresponding to the shape of the fixing projection (416), and preferably formed to have a semicircular shape so that the first locking unit (410) can be easily separated from and fixed to the first locking support (130).

[0059] Additionally, the helmet body (100) is formed in the upper central portion, and a second locking support portion (140) is configured to support the insertion and seating of a second locking unit (430) so that the cooling body (200) can be detachably coupled to the helmet body (100).

[0060] The second locking support member (140) is configured to include a through hole (142) formed to allow the plug member (432) and double sealing member (434) of the second locking unit (430), which will be described later, to pass through and be coupled with the main body fixing member (210) of the cooling main body part (200), and a seating groove (144) formed on the upper circumferential surface of the through hole (142) and configured to allow the lower main body part (450) of the locking main body part (436) included in the second locking unit (430) to be seated and fixed.

[0061] The helmet body (100) configured in this manner can be made of EPP (Expanded Poly-Propylene) material and can be manufactured using a foam molding method.

[0062] Here, EPP (Expanded Poly-Propylene) refers to spherical particles produced by physically (non-crosslinking) foaming Poly-Propylene, a general-purpose plastic, without using a chemical foaming agent. This allows for the lightweighting of the helmet body (100), facilitates easy processing such as recycling and reuse of raw materials after crushing, thereby enabling resource conservation and energy saving. Furthermore, it has the advantage of excellent energy absorption over a wide temperature range (-40-110℃) and minimal dimensional change with temperature. Additionally, because it possesses appropriate strength, flexibility, thermal insulation, and elasticity in a semi-rigid state, it can be manufactured to provide excellent absorption for external and repeated impacts, thereby protecting the user's head.

[0063] In addition, the helmet body (100) can be configured so that the surface tensile strength and compressive strength of the helmet body (100), as well as the waterproofing function, can be improved by performing a glazing process on the entire surface of the helmet body (100).

[0064] However, it is not limited to this, and the glazing method may be performed only on the first and second locking support parts (130, 140) configured on the helmet body part (100) so that even if the cooling body part (200) and the cooling pad part (300) are repeatedly separated and combined from the helmet body part (100), the shape of the first and second locking support parts (130, 140) may not be deformed or damaged.

[0065]

[0066] The cooling main body (200) is filled with a refrigerant inside and is inserted into the second receiving portion (114) of the receiving portion (110) formed in the helmet main body (100), particularly the helmet main body (100), to release cold air toward the head (or scalp) of a user wearing the helmet main body (100), thereby reducing headaches caused by high fever in the head of a patient with a brain disease, thereby facilitating the hypothermia method for the patient's head.

[0067] This cooling body (200) is formed as an internal space, and a refrigerant charging section (202) in which refrigerant is charged is formed, and is configured to cool the charged refrigerant so that cold air is released for a certain period of time.

[0068] At this time, the refrigerant may be a medium similar to water, but is not limited to any type as long as it is a medium capable of cooling at 18°C ​​or lower.

[0069] In addition, a body fixing part (210) is formed in the upper central part of the cooling body part (200) to protrude upward and to support the body part (100) so that it can be detachably coupled to the helmet body part (100) by the second locking unit (430).

[0070] The main body fixing part (210) has a fastening flange (212) formed with screw threads on the outer surface to which a double sealing member (434) of a second locking unit (430) to be described later is screw-coupled, and a refrigerant charging hole (214) is formed to penetrate the center of the fastening flange (212) and to inject refrigerant into the refrigerant charging part (202).

[0071] This main body fixing part (210) is formed to have a predetermined groove shape along the outer surface, and a main body locking guide groove (216) is formed to guide the coupling direction so that the coupling protrusion (446) formed on the upper main body part (440) of the second locking unit (430) can be inserted and fixed.

[0072] At this time, the main body locking guide groove (216) may be composed of a vertical guide groove (216a) that guides the coupling projection (446) to be inserted in a vertical direction, and a horizontal guide groove (216b) formed to be orthogonal to the lower end of the vertical guide groove (216a).

[0073] Here, the horizontal guide groove (216b) may further be configured with an anti-loosening projection (230) that prevents the coupling projection (446) from being arbitrarily detached and separated from the main body locking guide groove (216).

[0074] Meanwhile, the cooling body (200) of the present invention is designed to maintain the initially designed thickness at a constant level during manufacturing.

[0075] When cooling of the refrigerant charged in the refrigerant charging part (202) is performed, a sagging prevention part (220) is formed to prevent the shape of the refrigerant charging part (202) of the cooling main body (200) from being deformed due to bulging or sagging caused by volume change.

[0076] Such a sagging prevention member (220) may be configured in the front and rear portions of the refrigerant charging portion (202), respectively, and may be composed of an upper sagging prevention member (222) formed in the shape of a groove on the upper surface of the cooling body portion (200) and coupled with the first sagging prevention projection (120) of the helmet body portion (100), and a lower sagging prevention member (224) formed coaxially with the upper sagging prevention member (222) and into which the second sagging prevention projection (320) formed on the cooling pad portion (300) is inserted.

[0077] Accordingly, the sagging prevention part (220) of the present invention can simultaneously perform the role of supporting the helmet main body part (100), the cooling main body part (200), and the cooling pad part (300) so that they can all be combined in a coaxial line.

[0078] The cooling body part (200) of the present invention configured in this manner can be manufactured with a high content of 99% or more Bio-based PCM, and can be manufactured in a shape corresponding to the shape of the user's head so as to be able to deliver uniform cooling to the entire surface of the user's head.

[0079] Here, PCM (Phase Change Material) is a phase change material that represents an energy storage material capable of storing or releasing heat in the form of latent heat while maintaining a constant temperature when changing state from solid to liquid or from liquid to solid depending on changes in ambient temperature. It has the advantage of having a higher freezing point than water or other liquids, a longer temperature holding time, and no deformation of the original form even if cooling and melting are repeated multiple times.

[0080]

[0081] The cooling pad portion (300) is configured to provide a predetermined gap between the user's head and the cooling body portion (200) to prevent the refrigerant from dissolving more rapidly due to heat generated from the user's head by direct contact between the user's head portion and the cooling body portion (200), thereby allowing the user to receive cold air for a longer period of time, and to prevent frostbite on the user's scalp that may occur when the user puts on a helmet immediately after the refrigerant, which is set to a low temperature and frozen, is installed inside the device.

[0082] This cooling pad portion (300) is detachably inserted into a first receiving portion (112) formed in the helmet body portion (100), and is configured so that its upper surface is in close contact with the cooling body portion (200), and is configured to be fixed to the helmet body portion (100) by a first locking unit (410).

[0083] In addition, the cooling pad portion (300) is formed to extend downward from the inner portion and is configured to make direct contact with the user's head, so that when the helmet body portion (100) is worn, a separation rib (310) is formed to allow the user's head to be positioned at a distance from the cooling body portion (200).

[0084] Here, the spacing rib (310) may be formed in a honeycomb shape with a hexagonal lattice structure, but is not limited thereto, and may be derived from a three-dimensional lattice structure in the form of an array of pin-shaped protrusions, or a geometric shape of a square or circle, or a combination thereof.

[0085] It is preferable that the cooling pad portion (300) of the present invention be configured so that the surface portion that comes into direct contact with the cooling main body portion (200) and the separation rib (310) that comes into contact with the user's head have different material properties.

[0086] That is, the surface portion can be manufactured to be rigid, and the separation rib (310) can be manufactured to have flexibility.

[0087] In addition, the cooling pad section (300) is formed with a space formed by a spacer rib (310), and a refrigerant inlet groove (330) can be further formed to allow cold air emitted from the cooling main body section (200) to flow in and deliver cold air to the user's head for a longer period of time.

[0088] This cooling pad part (300) is formed coaxially with the lower sag prevention part (224) among the sag prevention parts (220) of the cooling main body part (200), and a second sag prevention protrusion (320) is formed to support the lower sag prevention part (224) so ​​that a close connection between the cooling pad part (300) and the cooling main body part (200) can be formed.

[0089] Here, the second anti-sagging protrusion (320) can be formed to protrude from the upper surface of the cooling pad portion (300).

[0090] The cooling pad part (300) of the present invention configured in this manner can be manufactured by a hot forming method, and can be manufactured from a TPE (Thermo Plastic Elastomer) material to maximize the contact cooling sensitivity.

[0091] At this time, TPE (Thermo Plastic Elastomer) is a high-performance eco-friendly material that provides not only the high elasticity, high strength, and high elastic resistance of rubber, but also injection molding processing, safety against toxicity, hardness, excellent color, texture, soft weather resistance, fatigue resistance, and heat resistance, and has the advantage of being very unlikely to pose a risk to the user's health even if direct contact with the user's head is made for a long time.

[0092]

[0093] The locking unit (400) is rotatably coupled to a first locking support (130) formed on the helmet body (100) and is composed of a first locking unit (410) that supports the cooling pad (300) so that it can be stably fixed to the helmet body (100), and a second locking unit (430) that is inserted into and seated on a second locking support (140) of the helmet body (100) and couples the cooling body (200) to the helmet body (100).

[0094] The first locking unit (410) has a rotation support member (134) inserted into the upper central portion, and a unit insertion groove (418) formed to guide rotation operation along the surface of the rotation support member (134).

[0095] At this time, the unit insertion groove (418) is configured so that the rotation shaft (412) can pass through it and be coupled with the rotation support member (134).

[0096] That is, the first locking unit (410) is rotatably coupled to the first locking support (130) by the rotation shaft (412).
