Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an inflatable heating pad for interventional surgery. Background Technology

[0002] Interventional surgery needs to be performed on a DSA machine, but the existing heating blankets cannot transmit X-rays, which affects the surgical field and increases the risk during the operation. In addition, the need for frequent replacement also leads to increased costs.

[0003] Application number CN211326511U discloses an intelligent inflatable heated mattress for DSA catheterization. The mattress comprises: an inflatable mattress body, an inflation port and an exhaust port on the mattress body, a hot air blower, an inflation pipe connecting the inflation port and the hot air blower, and a temperature sensor and a pressure sensor on the mattress body. Even in winter, the heating system in the catheterization room is not turned on to maintain a low temperature. Therefore, many patients undergoing interventional treatments in winter have a poor experience with the catheterization room: it's too cold, they are prone to catching a cold during the procedure, and the catheterization bed is too hard and uncomfortable. This disclosure uses a hot air blower to achieve a warming effect, but it lacks corresponding interventional surgical techniques and cannot be used in conjunction with X-rays for DSA interventional surgery. It can only be used as a warming device and still has room for improvement. Utility Model Content

[0004] To overcome the interference of heating materials with the surgical field of view under X-ray in the prior art, this utility model provides an inflatable heating pad for interventional surgery, including a DSA mattress. An air inlet pipe is fixedly installed on the inner wall of the DSA mattress, and a three-way connector is fixedly installed at the air outlet end of the air inlet pipe. An air outlet pipe is fixedly installed on the inner wall of the DSA mattress.

[0005] The DSA mattress has a tube groove inside, and a medical plastic tube is fixedly installed inside the tube groove. The top of the medical plastic tube has an air outlet, and the outer wall of the medical plastic tube is fixedly connected to the air outlet end of the tee connector.

[0006] The DSA mattress has a groove inside, and a compression spring is fixedly installed inside the groove. A heat-conducting plate is fixedly installed on the outer wall of the compression spring.

[0007] Preferably, there are three pipe channels and three medical plastic tubes, and two ventilation tubes are fixedly installed on the inner wall of the DSA mattress, with both ends of the two ventilation tubes extending into the interior of the pipe channel.

[0008] Ventilation ducts can transfer and circulate hot air between the ducts, ensuring uniform heating.

[0009] Preferably, the ventilation pipe on the right side is fixedly connected to the air outlet pipe.

[0010] The exhaust pipe provides a channel for hot air to escape.

[0011] Preferably, the retractable spring includes a spring seat and a telescopic spring, with the spring seat fixedly installed inside the groove, one end of the telescopic spring fixedly installed inside the spring seat, and the other end fixedly installed with a heat-conducting plate.

[0012] The retractable springs can move the heat-conducting plate up and down, allowing it to retract and fit into the DSA mattress when under load.

[0013] Preferably, the number of heat-conducting plates is three, and a sponge pad is fixedly installed on the top of each of the three heat-conducting plates.

[0014] The heat-conducting plate has a mesh design, which can improve the efficiency of heat conduction and heat retention without affecting X-ray penetration, and prevent hot gas from flowing out of the exhaust pipe too quickly, thus avoiding the problem of slow heating efficiency.

[0015] Preferably, the material of the tee connector is PVC plastic.

[0016] Preferably, the DSA mattress is covered with an outer cover.

[0017] The outer cover can enclose the DSA mattress and heating plate and other components in one piece, making it easy to use and operate.

[0018] Preferably, the inner wall of the outer cover has two slots, and the air inlet pipe and the air outlet pipe are adapted to the slots.

[0019] The empty slot is used to provide installation space for the air inlet and outlet pipes.

[0020] Beneficial effects:

[0021] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0022] (1) The inlet pipe is connected to the heating machine, so that hot gas is directly delivered to the three-way connector and medical plastic tube through the inlet pipe, and discharged to the space between the DSA mattress and the heat conduction plate through the outlet. The mesh heat conduction plate can quickly conduct heat and store heat, and continuously provide heat to the sponge pad on the top of the heat conduction plate to raise the body temperature of the surgical patient and avoid excessive blood loss and hypothermia.

[0023] (2) Since the DSA mattress and the sponge pad are both made of X-ray transparent materials, they can provide visual assistance to medical staff for surgery. The heating method through medical plastic tubes and heat-conducting plates will not block X-rays, thereby improving the safety of the surgery process and avoiding the defects of many blind spots caused by the traditional method of increasing the body temperature of patients by laying heating blankets.

[0024] (3) By covering the DSA mattress and heating plate with an outer cover, an integrated effect can be achieved, eliminating the need for additional heating blankets. The blankets can be reused, reducing costs and surgical preparation time, thus saving valuable time for the surgery. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] This implementation method is successful. The specific implementation method is as follows:

[0033] like Figures 1 to 4 As shown, in this embodiment 1, the outer cover 7 covers the outside of the DSA mattress 1 and the sponge pad 81 to form a whole. The patient lies on the surface of the outer cover 7. The compression spring 5 contracts under the weight and causes the heat conduction plate 8 to drop and fit against the DSA mattress 1. The compression spring 5 not only plays a role in deformation and fit, but also works with the sponge pad 81 to improve comfort and reduce the discomfort caused by the heat conduction plate 8.

[0034] It should be noted that the inner wall of the outer cover 7 has two slots. The slots are used to provide space for installing the air inlet pipe 2 and the air outlet pipe 3. The ends of the air inlet pipe 2 and the air outlet pipe 3 that are away from the DSA mattress 1 pass through the slots and extend to the outside of the outer cover 7.

[0035] like Figures 1 to 4 As shown, in this embodiment 2, the air inlet tube 2 is used to connect to the heating machine. The air inlet tube 2 and three medical plastic tubes 4 are connected simultaneously through a PVC three-way connector 21. The PVC three-way connector 21 can withstand high temperatures and thus serve to transport hot air. When the gas enters the medical plastic tube 4, it will be discharged into the DSA mattress 1 through the air outlet 41. At the same time, due to the patient's own weight compressing and contracting the spring 5, the heat conduction plate 8 will fit with the DSA mattress 1 to form a sealed space to gradually raise the temperature and transfer it to the sponge pad 81 through the heat conduction plate 8, thereby raising the patient's body temperature during the operation.

[0036] In addition, the heat-conducting plate 8 is a mesh plate with a "U" shape. The heat-conducting plate 8 located above the air outlet 41 is where the patient's ankle is placed. It can absorb and store the heat discharged from the air outlet 41 to the greatest extent. At the same time, the heat-conducting plate 8 is gradually distributed throughout the sponge pad 81 according to its shape, avoiding the problem of insufficient heating effect caused by the direct discharge of hot air through the air outlet 3, and does not affect the X-ray irradiation of the human torso and limbs.

[0037] like Figures 1 to 4 As shown, in this embodiment 3, the three tube grooves 10 in the DSA mattress 1 are interconnected by the ventilation pipe 6, and the air outlet pipe 3 is also connected to one of the tube grooves 10 and the ventilation pipe 6, so that the gas entering the DSA mattress 1 through the air inlet pipe 2 can be effectively discharged.

[0038] Furthermore, using medical plastic tube 4 to supply air to raise the patient's body temperature during DSA surgery is more advantageous than the existing method of using a heating blanket. It not only solves the problem of heating blankets not being able to transmit X-rays, which limits the surgical field of view, but also allows for recycling due to the integrated design, which eliminates the material waste of traditional disposable heating blankets, saves costs, reduces the cost of heating during surgery, and makes the operation more efficient and convenient.

[0039] Working principle:

[0040] By fitting the outer cover 7 onto the outside of the DSA mattress 1 and the heat-conducting plate 8 to form a single unit, the patient lies on the heat-conducting plate 8 covered with a sponge pad 81 during surgery. The compression spring 5 contracts under the pressure of the patient's own weight, causing the heat-conducting plate 8 to adhere to the DSA mattress 1. Simultaneously, the heating unit is connected to the air inlet pipe 2, delivering hot air through the three-way connector 21 to three medical plastic tubes 4. These medical plastic tubes 4 are made of high-transmittance plastics such as PE and PS, allowing X-rays to penetrate. The heat is delivered through the top of the three medical plastic tubes 4. The air outlet 41 evenly delivers hot air to the internal environment formed by the entire DSA mattress 1 and the heat conduction plate 8. Through thermal conductivity, the heat energy is transferred to the sponge pad 81 and the patient on top, so that the patient's body temperature can be maintained in the context of blood loss during surgery. In addition, since the sponge pad 81, medical plastic tube 4 and mesh heat conduction plate 8 can be transmitted by X-rays, the obstruction of the surgical field of vision is avoided. The heat conduction plate 8 can also improve the overall structural strength and reliability. Furthermore, there is no need for personnel to lay out disposable heating blankets, which can save time for surgery.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
