[0002] For patients with severe trauma and massive bleeding, a large loss of blood volume may cause shock or even death at any time. Usually, the stored blood in the blood bank needs to be stored in a refrigerator, generally at a temperature of 4℃±2℃. When rescuing patients in critical moments, a large amount of blood transfusion and infusion are often required to replenish blood volume.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, they cannot be understood as limitations on the embodiments of the utility model.

[0044] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0045] In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0047] The embodiment of the utility model discloses a heatable infusion set, which is used to solve the technical problem that the existing heatable infusion set uses a heater to wrap the infusion tube, but the infusion tube line is long, and bubbles will be generated when the liquid is heated. The bubbles are easily transported into the patient's body to cause air embolism, and even endanger the patient's life, which has a high medical risk.

[0048] See also Figure 1-2 , an embodiment of the utility model provides a heatable infusion set, comprising: a heat conducting device 3, a fluid filling device 5 and a heating device 4;

[0049] The heat conducting device 3 is used to place the infusion bag 1, and the heat conducting device 3 includes at least one deformation portion 31;

[0050] The fluid filling device 5 is connected to the heat conducting device 3, and is used to fill the fluid into the deformable portion 31, so that the deformable portion 31 is deformed, thereby causing the heat conducting device 3 to squeeze the infusion bag 1;

[0051] The heating device 4 is connected to the heat conducting device 3 , and is used to provide heat to the heat conducting device 3 .

[0052] It should be noted that the heat conducting device 3 includes at least one deformable portion 31, and the fluid filling device 5 fills the deformable portion 31 with fluid, so that the deformable portion 31 is deformed, thereby squeezing the infusion bag 1 placed in the heat conducting device 3;

[0053] The heating device 4 is connected to the heat conducting device 3 to provide heat to the heat conducting device 3, so that when the heat conducting device 3 squeezes the infusion bag 1, the liquid in the infusion bag 1 can be heated, and the bubbles generated by the temperature rise float on the top of the liquid and remain in the infusion bag 1, so as to ensure that there are no bubbles in the liquid flowing into the infusion tube 7 from the infusion bag 1 as much as possible, effectively avoiding the situation where bubbles are transported into the patient's body to cause air embolism, reducing medical risks and improving the safety of infusion;

[0054] In addition, for patients with massive bleeding, rapid infusion is of paramount importance. The fluid replacement speed of deep venous catheterization often fails to meet the requirements during major rescue, and manual push and pressurized infusion are usually required to increase the infusion speed. In this embodiment, the heating device 4 is connected to the heat conducting device 3 to provide heat to the heat conducting device 3. When the heat conducting device 3 squeezes the infusion bag 1, the infusion bag 1 can be heated more fully, and the speed at which the liquid in the infusion bag 1 flows to the infusion tube 7 can be accelerated, thereby improving the infusion speed.

[0055] In a more specific embodiment, a fixing device 2 is provided on the heat conducting device 3, and the fixing device 2 is used to fix the infusion bag 1 on the heat conducting device 3. The fixing device 2 can be a hook, or a Velcro or a clip, etc., to facilitate the disassembly of the infusion bag 1.

[0056] See also Figure 1 In a more specific embodiment, the heat conducting device 3 further includes a rigid portion 32, and the inner side surface of the rigid portion 32 is connected to the outer side surface of the deformation portion 31;

[0057] The deformation part 32 is used for squeezing the infusion bag 1 with the inner side surface of the deformation part 31 after the deformation part 31 is deformed.

[0058] It should be noted that when the deformable portion 31 is deformed, the inner side of the deformable portion 31 contacts and squeezes the infusion bag 1 , while the outer side of the deformable portion 31 is connected to the rigid portion 32 , thus maintaining the appearance of the heat conducting device 3 unchanged.

[0059] When the heat conducting device 3 only has the deformable portion 31 , the deformable portion 31 deforms to squeeze the infusion bag 1 .

[0060] In another more specific embodiment, the heat conducting device further comprises a rigid portion, wherein an outer side surface of the rigid portion is connected to an inner side surface of the deformable portion;

[0061] The rigid part is used for squeezing the infusion bag with the inner side surface of the rigid part after the deformable part is deformed.

[0062] It should be noted that in order to observe the deformation state of the deformable part, the deformable part is arranged outside the rigid part, so that after the deformable part is deformed, it pushes the rigid part to squeeze the infusion bag, and the infusion bag can also be pressurized.

[0063] See also Figure 2 As a further improvement, the heating device 4 is connected to the position of the deformation part 31 close to the infusion bag 1, and the heating device 4 is used to be close to the infusion bag 1 when the deformation part 31 is deformed.

[0064] It should be noted that the heating device 4 is connected to the position of the deformation part 31 close to the infusion bag 1, so that when the deformation part 31 is deformed, the heating device 4 first contacts the infusion bag 1. The heating device 4 is located between the infusion bag 1 and the deformation part 31, so that the heating device 4 can directly heat the infusion bag 1, and the deformation part 31 can prompt the heating device 4 to heat the infusion bag 1 more closely to avoid heat loss.

[0065] The heating device 4 is connected to the lower part of the entire deformation portion 31, so that the heating device 4 can be close to the lower part of the infusion bag 1, and can heat the liquid in the infusion bag 1 even if the amount of liquid in the infusion bag 1 is very small.

[0066] In specific implementation, the heating device 4 can be a disposable heating sheet that generates heat on its own, or an electric heating sheet;

[0067] In a specific embodiment, the heating device 4 is a disposable heating sheet that generates heat by itself. The heating device 4 can be closely attached to the inner side or outer side of the deformed portion 31. When a disposable heating sheet is used, the complexity of the system can be reduced, making it convenient for the staff to use.

[0068] See also Figure 1 In another more specific embodiment, the heating device 4 uses an electric heating plate, which is fixed on the inner side or outer side of the deformation part 31. The electric heating plate is connected to the temperature control device and the power switch 9 through the wire 10. The temperature of the electric heating plate is adjusted by the temperature control device and the power switch 9. For example, the temperature is adjusted high at the beginning and then lowered later. The temperature control device and the power switch 9 are used to gradually reduce the working temperature of the heating device in a preset manner according to the user's setting. This method is a prior art and will not be described in detail here.

[0069] See also Figure 2 In a more specific embodiment, the fluid-filled device 5 includes an inflating bag 51 and a catheter 52;

[0070] A first end of the conduit 52 is connected to the inflating bag 51 , a second end of the conduit 52 is connected to the deformation portion 31 , and a valve 53 is provided on the conduit 52 .

[0071] It should be noted that the air bag 51 is connected to the deformation part 31 through the catheter 52, and the valve 53 is a three-way valve. When the valve 53 is rotated to the open direction, the catheter 52 is opened, and the air bag 51 is manually / electrically squeezed, and the gas can enter the deformation part 31 through the catheter 52. When the inflation is completed, the valve 53 is rotated to the closed direction to block the catheter 52 to prevent the gas in the deformation part 31 from flowing back to the air bag 51 and reduce air leakage. When the infusion is completed, the valve 53 is rotated to the open direction to deflate and discharge the gas in the deformation part 31.

[0072] In another more specific embodiment, the fluid filled into the deformable part 31 by the fluid filling device 5 can be a non-heat-conducting medium or a heat-conducting medium (heat-conducting oil, hot air, etc.). The heat-conducting medium is filled into the deformable part 31, so that the deformable part 31 can also be heated when squeezing the infusion bag 1.

[0073] See also Figure 1-6 , as a further improvement, further comprising: a detection device 6, a clamping device 8 and a controller 11;

[0074] The detection device 6 is electrically connected to the controller 11, and the controller 6 is electrically connected to the clamping device 8;

[0075] The detection device 6 and the clamping device 8 are used to be connected to the infusion tube 7 of the infusion bag 1, and the detection device 6 is located above the clamping device 8;

[0076] The detection device 6 is used to detect whether there is liquid passing through the infusion tube 7 , and the clamping device 8 is used to release or block the infusion tube 7 .

[0077] It should be noted that, in clinical practice, if care is not taken to ensure that the infusion is completed, air may enter the body through the infusion tube 7, causing air embolism or blood return, which may lead to the risk of forming microthrombi.

[0078] When this embodiment is in use, the clamping device 8 is connected to the infusion tube 7;

[0079] The detection device 6 is connected to the infusion tube 7 to detect whether there is liquid passing through the infusion tube 7. When it is detected that no liquid is passing through, the detection device 6 sends a signal to the electrically connected controller 11. The controller 11 controls the electrically connected clamping device 8 to block the infusion tube 7 according to the signal to prevent air from entering the infusion tube 7 and also prevent blood from flowing back.

[0080] The detection device 6 is located above the clamping device 8. Since the liquid flows downward due to gravity, when the detection device 6 detects that no liquid passes, it can send a signal to the controller 11. The controller 11 immediately controls the clamping device 8 to block the infusion tube 7, thereby preventing air from entering the patient's body along the infusion tube 7 in a more timely manner.

[0081] The controller 11 can also control the clamping device 9 to release the infusion tube 7 according to the signal.

[0082] The detection device 6 is an infrared induction detector.

[0083] See also Figure 1-6 As a further improvement, the clamping device 8 includes a positioning clamp 81, a flow-stopping clamp 82, a releaser 83 and a fixing member 84;

[0084] The positioning clamp 81 is used to clamp the infusion tube 7, and the positioning clamp 81 is connected to the flow-stopping clamp 82;

[0085] The two clamping parts of the flow-stop clamp 82 are respectively connected to the releaser 83 and the fixing member 84, and the fixing member 84 is used to fix the releaser 83;

[0086] The controller 11 is electrically connected to the releaser 83;

[0087] The two clamping parts of the flow-stop clamp 82 are used to clamp the infusion tube 7 to block it after the releaser 83 is separated from the fixing member 84 , and are also used to release the infusion tube 7 when the fixing member 84 fixes the releaser 83 .

[0088] It should be noted that the positioning clamp 81 clamps the infusion tube 7 to connect the clamping device 8 to the infusion tube 7, but does not block the infusion tube 7;

[0089] The positioning clamp 81 is connected to the flow-stop clamp 82, so that when the positioning clamp 81 is clamped onto the infusion tube 7, the relative position between the flow-stop clamp 82 and the infusion tube 7 can also be fixed. In the initial state, when the flow-stop clamp 82 does not block the infusion tube 7, since the two clamping parts of the flow-stop clamp 82 are connected by a spring hinge, the fixing member 84 fixes the releaser 83, so the first ends of the two clamping parts of the flow-stop clamp 82 connected to the fixing member 84 and the releaser 83 are respectively closed, and the second ends of the two clamping parts are opened, and the second ends of the two clamping parts are respectively placed on both sides of the infusion tube 7; when the controller 11 receives the corresponding signal sent by the detection device 6, the controller 11 controls the releaser 83 to disengage from the fixing member 84, the first ends of the two clamping parts are opened, and the second ends are closed to clamp the infusion tube 7 to block it.

[0090] The controller 11 is a release motor, which is disposed on the flow-stop clamp 82 . The release motor is connected to the releaser 83 and drives the releaser 83 to disengage from the fixing member 84 .

[0091] The fixing member 84 is a fixing buckle, which is put on the releaser 8 for fixing.

[0092] The positioning clamp 81 includes two clamping parts, which are connected by a spring hinge. The positioning clamp 81 and the flow-stopping clamp 82 can share the same spring.

[0093] In another more specific embodiment, the clamping device 8 and the detection device 6 are detachably connected to the heat conducting device 3 to avoid loss.

[0094] See also Figure 6 As a further improvement, the positioning clip 81 is provided with a plurality of slots 811 of different sizes;

[0095] The plurality of slots 811 of different sizes are used to clamp infusion tubes 7 of different sizes.

[0096] It should be noted that, in order to clamp the infusion tubes 7 of different sizes, a plurality of slots 811 of different sizes are provided on the positioning clamp 81 for the infusion tubes 7 of different sizes to pass through, thereby ensuring more stable clamping.

[0097] See also Figure 1 As a further improvement, it also includes: an alarm (not shown in the figure), and the alarm is electrically connected to the detection device 6.

[0098] It should be noted that the alarm is electrically connected to the detection device 6, so that when the detection device 6 detects that there is no liquid passing through the infusion tube 7, a signal is sent to the alarm. The alarm sounds an alarm based on the signal to notify medical staff to replace the infusion bag 1 or remove the infusion bag 1 in time.

[0099] See also Figure 1-2 As a further improvement, a suspension device 12 is provided on the heat conducting device 3, and the suspension device 12 is used to fix the heat conducting device 3 on the infusion stand.
