Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a diagonal medical constant temperature bag. Background Art
[0002] Peritoneal dialysis (PD) uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through the peritoneal dialysis tube by gravity. Due to the concentration gradient difference of the solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); and the water moves from the low-osmotic side to the high-osmotic side (osmotic effect). The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.
[0003] The volume of peritoneal dialysis fluid prepared by general hospitals is usually 2000ml. The amount of dialysis fluid exchanged during peritoneal dialysis is 50ml / kg body weight. One bag of dialysis fluid can be used once by a patient weighing about 40kg. However, each patient's weight is different, and some patients will have some dialysis fluid remaining in the dialysis bag after a single dialysis. In order to prevent infection, a disposable dialysis bag is used, and the dialysis bag can only be connected to the peritoneal dialysis tube on the body once, so the patient can only directly discard the remaining dialysis fluid.
[0004] In order to avoid wasting the remaining dialysate by directly discarding it, some patients want to keep the dialysis bag containing the remaining dialysate connected to their body and use it again during the next dialysis. However, the existing dialysis bag solution brings some problems: (1) During the interval between two dialysis sessions, the dialysis bag connected to the patient will cause inconvenience to the patient's movement; (2) The dialysate in the dialysis bag gradually cools down, so that the dialysate does not reach the required temperature during the next dialysis.

[0015] In order to improve the heat preservation effect of the cross-body medical constant temperature bag, the bag body is provided with a flip cover covering the opening.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] like Figures 1 to 3 The figure shows a preferred embodiment of the cross-body medical thermostatic bag in the embodiment of the utility model. Specifically, the cross-body medical thermostatic bag comprises a bag body 1 and a cross-body shoulder strap 2 connected to the bag body 1. The patient can place the dialysis bag with remaining dialysis fluid in the bag body 1 and carry the cross-body medical thermostatic bag on the body through the cross-body shoulder strap 2, so that the patient can carry the dialysis bag anywhere.
[0022] In this embodiment, the bag body 1 is made of a single piece of sewing, and an opening for taking out and placing the dialysis bag is provided on the bag body 1.
[0023] In order to prevent the heat loss in the bag 1, the bag 1 is provided with a flap 16 for covering the opening, and a snap 161 is provided between the flap 16 and the bag 1 to connect the flap 16 and the bag 1. In order to make the bag 1 not only slow down the heat loss, but more importantly, to ensure that the remaining dialysate in the dialysis bag can reach the specified temperature during the secondary dialysis, the utility model also provides a heating component for heating the dialysate on the bag 1.
[0024] Specifically, the bag 1 includes an inner layer 11 and an outer layer 12, both of which are insulating and waterproof materials; a heating component is provided between the inner layer 11 and the outer layer 12 for heating the dialysate in the bag, and a control switch 130 is also provided on the outer surface of the bag 1. The patient starts or turns off the heating function of the heating component through the control switch 130. Specifically, the heating component includes a power supply (not shown in the figure), a controller 131, a heating element 132 and a first temperature detector 133. The heating element 132 and the first temperature detector 133 are respectively connected to the controller 131, and the power supply supplies power to the heating element 132; the heating element 132 is a heating wire, and the heating element 132 is S-shaped and distributed in the gap between the inner layer 11 and the outer layer 12. A plurality of first temperature detectors 133 are evenly arranged in the area where the heating wire is located. The first temperature detector 133 is close to the heating wire and is used to measure the temperature of the heating wire; the first temperature detector 133 transmits the detected temperature signal to the controller 131, and then the controller 131 turns on or off the heating element 132 according to the temperature signal to start or turn off the heating work of the heating element. When the temperature of the dialysate is lower than the specified temperature, the patient turns on the control switch 130 to start the heating element 132 for heating; when the first temperature detector 133 detects that the temperature of the heating wire is greater than the first set temperature, the first temperature detector 133 transmits the temperature signal to the controller 131, and then the controller 131 turns off the heating element 132 so that the heating element 132 stops heating; when the first temperature detector 133 detects that the temperature of the heating wire is lower than the first set temperature, the first temperature detector 133 transmits the temperature signal to the controller 131, and then the controller 131 turns on the heating element 132 for heating. Here, the controller 131 turns off the heating element 132 by controlling the first switch 1321 on the heating element 132. Because the highest temperature of the dialysate when in use is generally 45°C, it is not advisable to heat the dialysate above 45°C. The heat of the heating wire is transmitted to the dialysate with a certain hysteresis. If the temperature of the heating wire is too high, the temperature of the dialysate will exceed 45°C, so the heating wire for heating does not exceed the first set temperature of 50°C.
[0025] In the process of heating the dialysate, in order to more accurately control the temperature of the dialysate, a second temperature detector 134 is further provided in the bag 1, and the second temperature detector 134 is connected to the controller 131. The second temperature detector 134 is used to detect the temperature of the air inside the bag 1 and transmit the temperature signal to the controller 131, and then the controller 131 turns on or off the heating element 132 according to the temperature signal. When the temperature of the dialysate is lower than the specified temperature, the patient turns on the control switch 130 to start the heating element 132 for heating; when the second temperature detector 134 detects that the temperature of the air inside the bag 1 is greater than the second set temperature, the second temperature detector 134 transmits the temperature signal to the controller 131, and then the controller 131 turns off the heating element 132 so that the heating element 132 stops heating; when the second temperature detector 134 detects that the temperature of the air inside the bag 1 is lower than the second set temperature, the second temperature detector 134 transmits the temperature signal to the controller 131, and then the controller 131 turns on the heating element 132 so that the heating element 132 continues heating. Here, the controller 131 turns off the heating element 132 by controlling the second switch 1322 on the heating element 132. The temperature of the dialysate that can be input into the body is a range value, generally 37-45°C, so when the second temperature detector 134 detects that the temperature of the air inside the bag 1 is less than 37°C, 45°C or any value between 37-45°C, the heating element 132 is turned on so that the heating element 132 continues to heat, that is, the second set temperature can be any value between 37-45°C.
[0026] In this embodiment, the first switch 1321 and the second switch 1322 are connected in series, and the heating element 132 can generate heat only when both the first switch 1321 and the second switch 1322 are closed. In other embodiments, only one temperature control system may be provided to control whether the heating element 132 generates heat.
[0027] The package 1 is also provided with a temperature display 14, which is connected to the controller 131 and is used to display the temperature detected by the first temperature detector 133 and the second temperature detector 134. The patient can determine whether the dialysate needs to be heated according to the temperature displayed on the temperature display 14, or estimate the time required for heating and then arrange the dialysis reasonably.
[0028] In order to increase the application scenarios of the cross-body medical constant temperature bag, the above-mentioned power supply is a rechargeable power supply, and a USB socket 15 for charging the power supply is provided on the bag body 1, and the USB socket 15 is connected to the power input terminal of the power supply.
[0029] like Figure 3As shown, in order to prevent the heating element 132 from locally overheating, a signal line 135 is wound around the heating element 132 in the cross-body medical constant temperature bag. The signal line 135 is connected to the controller 131. When the local temperature of the heating wire exceeds a predetermined value, the signal line 135 changes from an insulator to a good conductor, causing the circuit in the bag 1 to short-circuit and cut off the power, thereby achieving the purpose of safety protection.
[0030] In addition, the signal line 135 is wound around the heating element 132 , and the outside of the wound signal line 135 and the heating element 132 is coated with a heat-resistant resin layer that wraps the signal line 135 and the heating element 132 , and the resin layer also plays an insulating role.
