Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a perineum cold and hot compress device. Background Art

[0002] Perineal cold compress and hot compress are both commonly used nursing methods in obstetrics and gynecology. Perineal cold compress acts on the perineum through low-temperature substances, stimulating the perineum to drop in temperature, causing vasoconstriction, slowing metabolism, reducing vascular inflammatory exudation factors, and reducing bleeding, which has the effect of reducing swelling and relieving pain, and can reduce the perineal pain index. Perineal hot compress can promote local blood circulation, enhance leukocyte phagocytosis and tissue vitality, help relieve swelling, stimulate the growth and repair of local tissues, and can be used for parturients with perineal edema, hematoma, incision induration and early infection. Patients may only apply perineal cold compress or hot compress, or they may alternate between cold and hot compress.

[0003] Currently, cold compresses on the perineum mainly use ice bags as cooling sources, while hot compresses on the perineum use hot water bags as heating sources. The cooling and heating time of ice bags and hot water bags are both short, and they need to be replaced after a period of use. Moreover, if the mother or patient needs to alternate cold and hot compresses, the ice bag and hot water bag need to be replaced, which is not convenient.

[0004] After searching, some patents disclosed technologies related to cold and hot compresses of the perineum. For example, the Chinese patent with application number 202021450286.0 discloses a pair of pants for cold or hot compresses of the perineum, including a front trouser surface and a back trouser surface, and also includes a water bag with multiple water collection chambers inside. An isolation belt is provided between two adjacent water collection chambers, and a vent is provided on the isolation belt. The vent runs through the upper and lower surfaces of the water bag, and the vent and the water collection chamber are blocked by the isolation belt; the water bag is located between the bottom end of the front trouser surface and the bottom end of the back trouser surface, and a liquid inlet is provided on the water bag. Cold solution or hot solution is added to the inside of the water bag through the liquid inlet, and then the patient is subjected to cold or hot compress; an isolation belt is provided between two adjacent water collection chambers, so that the contact area between the water bag and the patient's vulva can be increased during use, so that the water bag can effectively fit the patient's vulva and improve the treatment effect on the patient; and vents are provided on the isolation belt, so as to improve the comfort of the patient.

[0005] The above-mentioned pants for cold or hot compress of perineum still add cold solution or hot solution to the water bag, and the temperature of the cold solution or hot solution still rises or drops to room temperature after a period of time, and loses the cold or hot compress effect. It is still necessary to add cold solution or hot solution after a period of time, which is inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 7 As shown, the perineal hot and cold compress device includes a hot and cold compress instrument 1 and a hot and cold compress pad 2; the hot and cold compress pad 2 includes a water bag outer shell 22 and a flat water bag 21, one side of the water bag outer shell 22 is a water-absorbing flexible pad 221; the flat water bag 21 is placed in the water bag outer shell 22, and the flat water bag 21 includes a water bag body 211, a water bag water inlet pipe 212 and a water bag water return joint 213, one end of the water bag body 211 is a water bag connecting end, the water bag water inlet pipe 212 is connected to the water bag connecting end and extends to the other end of the flat water bag 21, and the water bag water return joint 213 is connected to the water bag connecting end; the hot and cold compress instrument 1 includes a hot water container 12, a cold water container The flat water bag 21 comprises a heating structure 14, a refrigeration structure 15, a water supply structure 16 and a reflux structure 17. The heating structure 14 and the refrigeration structure 15 act on the hot water container 12 and the cold water container 13 respectively. The water supply structure 16 is connected with the water bag water inlet pipe 212, the hot water container 12 and the cold water container 13. The reflux structure 17 is connected with the water bag water return joint 213, the hot water container 12 and the cold water container 13. The water supply structure 16 can output the water in the hot water container 12 or the cold water container 13 to the flat water bag 21. The reflux structure 17 can return the water in the flat water bag 21 to the hot water container 12 or the cold water container 13.

[0031] When the utility model is used, the hot and cold compress instrument 1 is placed beside the bed, and the hot and cold compress pad 2 is attached to the perineum, specifically, the water-absorbing flexible pad 221 is attached to the perineum. The water supply structure 16 and the reflux structure 17 are respectively connected to the water bag water inlet pipe 212 and the water bag water return joint 213. Water is added to the hot water container 12 and the cold water container 13 respectively. The heating structure 14 and the refrigeration structure 15 heat and cool the hot water container 12 and the cold water container 13 respectively to obtain hot water and ice water. The water supply structure 16 supplies the hot water in the hot water container 12 to the flat water bag 21, and the water flows back through the reflux structure 17; the hot water circulates continuously in the flat water bag 21 or circulates once at intervals to keep the flat water bag 21 at a high temperature, and the heat is transferred to the water-absorbing flexible pad 221, and then transferred to the perineum to achieve perineal hot compress. The water supply structure 16 supplies the ice water in the cold water container 13 to the flat water bag 21 to achieve perineal hot compress.

[0032] It can be seen that the utility model can realize cold and hot compress of the perineum, and the cold and hot compress instrument 1 can automatically keep the cold and hot compress pad 2 at high or low temperature for a long time without manual intervention; the water supply structure 16 switches the connection state with the hot water container 12 and the cold water container 13 to switch between cold and hot compress of the perineum. Therefore, the utility model greatly facilitates cold and hot compress of the perineum.

[0033] The flat water bag 21 of the utility model can be used by a single person for a long time, but it is not suitable to change the user. The water bag cover 22 contacts the perineum, and the absorbent flexible pad 221 can absorb vaginal exudate (similar to a sanitary napkin). The water bag cover 22 should be replaced when it is seriously contaminated. The hot and cold compress instrument 1 can be used repeatedly for a long time.

[0034] The heating structure 14 and the cooling structure 15 both adopt the existing technology. The heating structure 14 can be a resistive heater, and the cooling structure 15 can be a semiconductor cooling module. The hot and cold compress instrument 1 can be provided with a temperature sensor to detect the water temperature and control the operation of the heating structure 14 and the cooling structure 15. The temperature required for hot compress of the perineum is about 45°C. Considering the loss of water transmission and heat transfer, the water temperature in the hot water container 12 can be maintained at 50°C to 55°C. When the temperature sensor detects that the water temperature in the hot water container 12 is lower than 50°C, the heating structure 14 is controlled to be turned on. When the temperature sensor detects that the water temperature in the hot water container 12 is higher than 55°C, the heating structure 14 is controlled to stop working. The temperature required for cold compress of the perineum is about 10°C. The water temperature in the cold water container 13 should be maintained below 6°C. When the temperature sensor detects that the water temperature in the cold water container 13 is higher than 6°C, the cooling structure 15 is controlled to be turned on. When the water temperature in the cold water container 13 is lower than 2°C, the cooling structure 15 is controlled to stop working.

[0035] The specific structure of the water supply structure 16 is as follows: the water supply structure 16 includes a water pump 161, an output main pipe 162, a first output branch pipe 163, a second output branch pipe 165, a first output valve 164 and a second output valve 166. The output main pipe 162 is connected to the water bag water inlet pipe 212, the water pump 161 is arranged on the output main pipe 162, the first output branch pipe 163 is connected to the hot water container 12 and the output main pipe 162 behind the water pump 161, the second output branch pipe 165 is connected to the hot water container 12 and the output main pipe 162 behind the water pump 161, and the first output valve 164 and the second output valve 166 are respectively arranged on the first output branch pipe 163 and the second output branch pipe 165.

[0036] When the first output valve 164 is opened and the second output valve 166 is closed, the water pump 161 is connected to the hot water container 12, and the water supply structure 16 supplies hot water to the flat water bag 21 to achieve hot compress. When the first output valve 164 is closed and the second output valve 166 is opened, the water pump 161 is connected to the cold water container 13, and the water supply structure 16 supplies ice water to the flat water bag 21 to achieve hot compress.

[0037] The specific structure of the reflux structure 17 is as follows: the reflux structure 17 includes a reflux main pipe 171, a first reflux branch pipe 172, a second reflux branch pipe 174, a first reflux valve 173 and a second reflux valve 175. The reflux main pipe 171 is connected to the water bag return joint 213, the first reflux branch pipe 172 is connected to the reflux main pipe 171 and the hot water container 12, the second reflux branch pipe 174 is connected to the reflux main pipe 171 and the cold water container 13, and the first reflux valve 173 and the second reflux valve 175 are respectively arranged on the first reflux branch pipe 172 and the second reflux branch pipe 174.

[0038] When the first return valve 173 is opened, water flows back to the hot water container 12, and when the second return valve 175 is opened, water flows back to the cold water container 13. When the first output valve 164 is opened, the first return valve 173 should be opened at the same time. When the second output valve 166 is opened, the second return valve 175 should be opened at the same time.

[0039] Furthermore, the preferred reflux structure 17 of the utility model includes a pressure-maintaining valve 176, which is arranged on the reflux main pipe 171; the pressure-maintaining valve 176 can be opened when the pressure reaches a set value, and closed when the pressure does not reach the set value. The pressure-maintaining valve 176 can be an existing pressure relief valve. The function of the pressure-maintaining valve is to maintain a certain water pressure in the flat water bag 21 when the water circulates continuously in the flat water bag, so that the flat water bag 21 remains inflated; to prevent too little water in the water bag 21 from affecting the effect of hot compress and cold compress.

[0040] The more specific structure of the hot and cold compress instrument 1 is preferably as follows: the hot and cold compress instrument 1 includes a housing 11, the housing 11 is divided into a first housing cavity 111, a second housing cavity 112 and a third housing cavity 115 by a partition 113, the hot water container 12 and the heating structure 14 are arranged in the first housing cavity 111, the cold water container 13 and the refrigeration structure 15 are arranged in the second housing cavity 112, and the water pump 161, the first output valve 164, the second output valve 166, the first return valve 173 and the second return valve 175 are arranged in the third housing cavity 115. A heat insulating material 114 is arranged on the partition 113 between the first housing cavity 111 and the second housing cavity 112.

[0041] This can prevent the heating and cooling of the hot and cold compress device 1 from affecting each other, resulting in poor heating and cooling efficiency.

[0042] The output pipe 162 of the water supply structure 16 and the return pipe 171 of the return structure 17 both need to extend out of the housing 11 for a long time in order to be connected to the flat water bag 21. After the perineal hot and cold compress device is used, the output pipe 162 and the return pipe 171 need to be stored. For the convenience of storage, the hot and cold compress device 1 preferably includes a cover plate 18; a storage cavity 116 is provided on the housing 11, and the storage cavity 116 is used to store the output pipe 162 and the return pipe 171 exposed from the housing 11; the cover plate 18 is connected to the housing 11 and covers the storage cavity 116.

[0043] The output main pipe 162 and the reflux structure 17 exposed from the shell 11 can be coiled into a circle and placed in the storage chamber 116, and then covered with a cover plate 18 to complete the storage.

[0044] As the name suggests, the flat water bag 21 should be flat so that it can be bent and the hot and cold compress pad 2 can fit the perineum better. In order to keep the flat water bag 21 flat and avoid a large bulge in the middle, the two sides of the bag body 211 are preferably connected by a plurality of spaced connecting belts 2111.

[0045] As mentioned above, the absorbent flexible pad 221 is in direct contact with the perineum, should have a good touch, and be able to absorb vaginal exudates (similar to a sanitary napkin in function). Therefore, the absorbent flexible pad 221 preferably has a structure similar to that of a sanitary napkin, that is, the absorbent flexible pad 221 includes a cotton surface layer 2211 and a high molecular absorbent resin 2212 disposed in the cotton surface layer 2211.

[0046] The hot and cold compress instrument 1 of the utility model is an electric instrument, which should be plugged in for use and conventionally have an electric control device, which is used to control the heating structure 14, the refrigeration structure 15, the water pump and the operation of each valve. The electric control device should have a cold compress button, a hot compress button and a stop button. When hot compress is needed, press the hot compress button, and the heating structure 14 is turned on; after the water temperature meets the requirements, the water pump 161 is turned on, the first output valve 164 is turned on, the second output valve 166 is closed, the first return valve 173 is turned on, and the second return valve 175 is closed. When cold compress is needed, press the cold compress button, and the refrigeration structure 15 is turned on; after the water temperature meets the requirements, the water pump 161 is turned on, the first output valve 164 is closed, the second output valve 166 is opened, the first return valve 173 is closed, and the second return valve 175 is opened. After the hot and cold compress is finished, press the stop button, the water pumps of the heating structure 14 and the refrigeration structure 15 stop working, and all valves are closed.
