Description

Technical Field

[0001] The utility model relates to the technical field of heating or cooling appliances for medical or human treatment, in particular to a medical inflatable warming blanket. Background Art

[0002] Maintaining the patient's body temperature not lower than the normal body temperature is an important link in preventing surgical risks during surgery. For many major surgeries or surgeries with a long anesthesia time requirement, during the surgery and during the patient's waking up period after the surgery, it is necessary to keep the patient's body temperature not lower than the normal body temperature.

[0003] Currently, the main medical warming blankets are water circulation warming blankets, electric heating warming blankets, and inflatable warming blankets. The water circulation warming blanket winds plastic water pipes inside the blanket and heats and circulates through a circulation pump. The disadvantage of this blanket is that the smell of plastic is very strong. Once the blanket body is punctured by surgical instruments, water will leak out and spray onto the patient and the instruments, posing a risk of contaminating the patient's wound and also causing electrical safety problems. The electric heating blanket is heated by electric heating wires. Once liquids such as blood, body fluids, and disinfectant liquids during the surgery seep in, there is a risk of electric shock, so the risk is very high.

[0004] In view of the poor safety of the above two warming blankets, most hospitals usually use inflatable warming blankets. The inflatable warming blanket is formed by stitching or integrally molding the upper and lower bottom cloth sheets to form a simple hollow airbag structure. The air inlet of the warming blanket is connected to the main unit of the warming blanket through a special hose interface. The main unit of the warming blanket transports warm air into the airbag, thereby warming and keeping the patient warm.

[0005] However, the existing inflatable warming blankets are mostly in regular rectangular shapes (i.e., sheet-like). When a patient lies on it, it can only warm and keep the back, buttocks, and the back of the legs warm, and cannot warm and keep the arms, hands, the sides and the front of the legs warm. In addition, the lower limb part of the existing inflatable warming blanket is a one-piece integral structure, and the two legs cannot be separated, which cannot meet the warming requirements of some surgical positions (such as the supine split-leg position, laparoscopic pancreaticoduodenectomy, laparoscopic radical gastrectomy, etc.). Content of the Utility Model

[0006] The purpose of the utility model is to provide a medical inflatable warming blanket that can comprehensively wrap and keep the patient's limbs warm and the lower limbs can be separated.

[0007] The medical inflatable warming blanket of the utility model comprises a surface layer and a bottom layer. The surface layer and the bottom layer are arranged in an upper-lower overlapping manner, and their outer edges are thermally pressed and bonded together to form a large airbag. An air inlet for connecting an external heat source supply device is arranged on the large airbag, and it is divided into an upper body part and a lower limb part from top to bottom. A head accommodation area is centrally arranged at the top of the upper body part. On both sides of the upper body trunk area below the head accommodation area, there are symmetrically connected with arm warming parts through a pair of tearing lines. The lower limb part includes a lower body trunk area which is an integral structure with the upper body trunk area, and a binding part and a wrapping part which are symmetrically arranged on the left and right sides of the lower body trunk area and are arranged up and down. The upper and lower edges of the binding part are respectively connected with the upper body part and the wrapping part through tearing line two and tearing line three.

[0008] In some embodiments, a tearing line four is centrally arranged in the lower body trunk area, and the tearing line four extends from the top to the bottom of the lower limb part.

[0009] In some embodiments, a binding strap is arranged on the binding part.

[0010] In some embodiments, a number of thermally pressed bonding points are evenly arranged on the arm warming part, the upper body trunk area, the lower body trunk area and the wrapping part, and the surface layer and the bottom layer are adhered and bonded at the thermally pressed bonding points.

[0011] In some embodiments, a thermally pressed bonding strip is arranged on one side of the arm warming part, the binding part and the wrapping part, and the surface layer and the bottom layer are adhered and bonded at the thermally pressed bonding strip.

[0012] In some embodiments, 2 to 3 thermally pressed bonding strips are evenly arranged at intervals along the width direction of each side of the binding part.

[0013] In some embodiments, the length L of the arm warming part is greater than or equal to 75 cm and the width W is greater than or equal to 45 cm.

[0014] In some embodiments, both the surface layer and the bottom layer are made of polypropylene non-woven fabric composite polyethylene film.

[0015] Based on the above technical solutions, the utility model has at least the following beneficial effects:

[0016] The medical inflatable warming blanket of the utility model is respectively provided with an arm warming part, a binding part and a wrapping part for wrapping the arms and legs on both sides of the upper body trunk area and the lower body trunk area. When the patient lies on the warming blanket, in addition to warming the back of the body, it can also warm and keep warm the arms, hands, the sides and the fronts of the legs, achieving all-round warming and keeping warm, significantly improving the warming effect, and providing an important guarantee for the smooth progress of the operation. In addition, the lower limb part of the warming blanket of the utility model can be divided into two pieces and can be used with the legs separated, better meeting the warming requirements of specific surgical positions (such as the supine position with legs separated, laparoscopic pancreaticoduodenectomy, laparoscopic radical gastrectomy, etc.), with stronger practicability and a wider scope of application.

[0017] The medical inflatable warming blanket of the utility model adopts a disposable design, ensuring that each patient can use a clean and hygienic warming blanket and avoiding the risk of cross-infection. Secondly, the warming blanket adopts an inflatable design and achieves the heat preservation effect through inflation, enabling the patient to maintain an appropriate temperature during the treatment process. In addition, after being inflated, the warming blanket is soft and comfortable, providing a good use experience for the patient. Moreover, the surface layer and the bottom layer of the warming blanket are both made of polypropylene non-woven fabric composite polyethylene film, with polypropylene non-woven fabric on the outer layer and polyethylene film on the inner layer. The soft and breathable polypropylene non-woven fabric can effectively protect the inner layer, and the polyethylene film has good heat preservation performance, which can effectively block the influence of the external temperature on the patient and can also effectively prevent air leakage.

[0022] AsFigure 1 As shown in:

[0023] The medical inflatable warming blanket of the present application includes a surface layer and a bottom layer arranged in an upper and lower stacked manner. Preferably, both the surface layer and the bottom layer in this embodiment are made of commonly used polypropylene non-woven fabric composite polyethylene film in the art through processes such as heat sealing, cutting, and sewing. The materials and processes are all prior arts and will not be elaborated here. The outer edges of the surface layer and the bottom layer are thermally pressed and bonded together to form a large airbag. An air inlet 11 is provided at the upper left corner of the large airbag. The air inlet 11 is externally connected to a commonly used hot gas source supply device in the art through a pipeline to input hot gas with appropriate temperature into the large airbag.

[0024] The warming blanket of the present application is divided into an upper body part 1 and a lower limb part 2 as a whole. In the upper body part 1, a head receiving area 12 is centrally provided at its top. Below the head receiving area 12 is the upper torso area 13. On both sides of the upper torso area 13, arm warming parts 15 are symmetrically connected through a first tearing line 14. The length L of the arm warming part 15 is greater than or equal to 75 cm (for an adult with a height of 170 cm, the arm length is 65 - 75 cm) and the width W is greater than or equal to 45 cm, so as to completely surround and wrap the patient's arm. When in use, the first tearing lines 14 on both sides are torn along the dotted lines, and the arm warming part 15 can be separated from the upper torso part 13, facilitating the free placement of the patient's arm. After placing the patient's arm on the arm warming part 15, the outer edge of the arm warming part 15 is folded towards the upper torso area 13 to wrap the patient's arm, and it is heated, ensuring that the front, side, and circumferential directions of the arm can be heated except for the back, significantly improving the warming effect.

[0025] The lower limb part 2 of the warming blanket of the present application includes a lower torso area 18, a binding part 16, and a wrapping part 17. The lower torso area 18 and the upper torso area 13 are of an integral structure. On the left side of the lower torso area 18, the binding part 16 and the wrapping part 17 are arranged vertically. On the right side of the lower torso area 18, there are binding part 16 and wrapping part 17 symmetric to those on the left side. The upper and lower edges of the binding part 16 are respectively connected to the upper body part 1 and the wrapping part 17 through a second tearing line 161 and a third tearing line 171. A fourth tearing line 19 is centrally provided in the lower torso area 18. The fourth tearing line 19 extends from the top to the bottom of the lower limb part 2. When in use, the lower limb part 2 can be separated into two parts by tearing along the dotted line of the fourth tearing line 19, facilitating heat preservation after the two legs are opened. After the two legs are opened, then tear along the dotted lines of the second tearing line 161 and the third tearing line 171, and respectively fold the binding part 16 and the wrapping part 17 on the left and right sides towards the body trunk. The binding part 16 covers the patient's abdomen and the upper part of the lower limbs, and the wrapping part 17 completely wraps the patient's lower limbs, thereby realizing the all-round covering and heat preservation of the bottom, side, and front of the patient's lower body. Preferably, a binding strap 20 is provided on the binding part 16 to play a role in restraining the lower limbs and improving the convenience of using the warming blanket.

[0026] In addition, after the patient lies down, the trunk and lower limb parts of the large airbag are easily flattened due to the load, and the hot air cannot effectively act on the patient. To evenly distribute the hot air in the large airbag, so that the patient's body is evenly heated and supported, a number of hot-press bonding points 21 are evenly arranged on the arm heating part 15, the upper trunk area 13, the lower trunk area 18 and the wrapping part 17 of the heating blanket of the present application. The surface layer and the bottom layer are bonded together at the hot-press bonding points 21, thereby dividing the large airbag into a number of small airbag areas. The hot air flow fills the small airbag areas, making the overall thickness of the heating blanket relatively uniform and the support strength relatively uniform after inflation, which is beneficial to improving the comfort of the patient during use and also achieves the purpose of uniform heating. Preferably, hot-press bonding strips 22 are also provided on the side of the arm heating part 15, the binding part 16 and the wrapping part 17 close to the trunk, and the surface layer and the bottom layer are also bonded together at the hot-press bonding strips 22. More preferably, 2 to 3 hot-press bonding strips 22 of the binding part 16 are evenly spaced along its width direction. The function of the hot-press bonding strip 22 is the same as that of the hot-press bonding point 21. The multiple hot-press bonding strips 22 cooperate with the hot-press bonding points 21 to divide the internal space of the large airbag into multiple interconnected areas, which is beneficial to achieving stable support and uniform heat preservation.

[0027] The medical inflatable heating blanket of the present utility model can cover and heat the back, side and front of the patient's body, thereby forming a warm current throughout the patient's body to achieve the purpose of keeping warm and raising the temperature. Moreover, the heating method of the present application is stable and effective, and there is no hidden danger of electric leakage after being exposed to water, and the use safety is extremely high.

[0028] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
