Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a surface preheating device for an ultrasound medical probe. Background Technology

[0002] Since ultrasound probes need to come into direct contact with the human body during use, in low-temperature conditions, a heating device is generally needed to preheat the ultrasound probe to raise the surface temperature of the part of the ultrasound probe that comes into contact with the human body to a certain temperature, so as to avoid causing discomfort to the patient and improve the patient's comfort during the examination.

[0003] Because the surface of an ultrasonic probe is curved rather than flat, when using a traditional ultrasonic probe preheating device, the heat source cannot fully adapt to the probe surface, resulting in uneven preheating distribution, large local temperature differences, and unsatisfactory results. Utility Model Content

[0004] The purpose of this invention is to provide a preheating device for the surface of an ultrasound medical probe that provides uniform preheating, effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An ultrasound medical probe surface preheating device includes a preheating box containing a preheating liquid. One side of the preheating box has a pick-up and drop hole for the ultrasound probe to enter and exit. An installation ring is sealed and fixed around the pick-up and drop hole on the inner wall of the preheating box. A fully unfolded, cylindrical flexible liquid-separating bag is fixed on the installation ring. A heating device is provided inside the preheating box for heating the preheating liquid.

[0007] It can be seen that after the probe is inserted into the flexible liquid-sealing bag, the flexible liquid-sealing bag is easily deformable. Under the pressure of the preheating liquid in the preheating box and its own rebound, the flexible liquid-sealing bag fits the probe surface more closely and adapts to the shape of the probe, so as to carry out comprehensive preheating. This avoids uneven preheating and temperature difference, and effectively improves the preheating effect of the probe.

[0008] Furthermore, a retaining sleeve is fixed around the take-up and take-down hole on the outer surface of the preheating box, and a rubber retaining sleeve is fixed on the inner wall of the retaining sleeve. The rubber retaining sleeve is interference-fitted with the outer peripheral surface of the ultrasonic probe.

[0009] Before inserting the ultrasonic probe into the flexible liquid-separating bag, the ultrasonic probe needs to be inserted through a retainer. The retainer is interference-fitted with the outer wall of the probe, creating compression and friction, which allows the ultrasonic probe to be held in place within the retainer. This facilitates the probe being held in the preheating box for preheating without the need for manual handling. After preheating, the probe can be pulled out directly. The structure is simple and the operation is convenient.

[0010] Furthermore, the preheating liquid used is water, and the preheating box is not filled with water.

[0011] Using water as the preheating liquid is low-cost and readily available, thereby reducing manufacturing costs.

[0012] Furthermore, the heating device uses electric heating rods, and the preheating box is equipped with at least four electric heating rods, which are evenly distributed around the flexible liquid-separating bag.

[0013] Ensure that the heating source is evenly distributed within the preheating box, providing multi-point heating for better heating effect.

[0014] Furthermore, a temperature controller is provided on the top of the preheating box, and the temperature sensing element of the temperature controller extends into the preheating box. The temperature controller is electrically connected to the electric heating rod.

[0015] Furthermore, a counterweight base is fixed to the bottom of the preheating box, and the bottom surface of the counterweight base has anti-slip texture.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] After the probe is inserted into the flexible liquid-sealing bag, the flexible liquid-sealing bag is easily deformable. Under the pressure of the preheating liquid in the preheating box and its own rebound, the flexible liquid-sealing bag fits the probe surface more closely and adapts to the shape of the probe, so as to carry out comprehensive preheating. This avoids uneven preheating and temperature difference, and effectively improves the preheating effect of the probe.

[0018] Before inserting the ultrasonic probe into the flexible liquid-separating bag, the ultrasonic probe needs to be inserted through a clamping sleeve, and the clamping sleeve is interference-fitted with the outer peripheral wall of the probe, resulting in squeezing and friction. This allows the ultrasonic probe to be stuck in the clamping sleeve, thus facilitating the probe to be kept on the preheating box for preheating without manual handling. After preheating is complete, the probe can be directly pulled out. The structure is simple and the operation is convenient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-4 This utility model provides an ultrasonic medical probe surface preheating device, including a preheating box 1 containing preheating liquid. One side of the preheating box 1 is provided with a pick-up and drop hole 11 for the ultrasonic probe to enter and exit. An installation ring 3 is sealed and fixed around the pick-up and drop hole 11 on the inner wall of the preheating box 1. A fully unfolded cylindrical flexible liquid-sealing bag 2 is fixed on the installation ring 3. The flexible liquid-sealing bag 2 has the ability to be easily deformed and has a certain elasticity. At the same time, the flexible liquid-sealing bag 2 has good waterproof effect, so that the preheating liquid in the preheating box 1 will not leak out. A heating device 4 is provided in the preheating box 1 for heating the preheating liquid.

[0028] When using the preheating device provided by this utility model to preheat the ultrasonic probe, the heating device 4 first heats the preheating liquid in the preheating box 1, keeping the preheating box 1 at a certain temperature. Then, the end of the ultrasonic probe that is in contact with the human body is inserted into the insertion / removal hole 11, and then into the flexible liquid-sealing bag 2. After the probe is inserted into the flexible liquid-sealing bag 2, because the flexible liquid-sealing bag 2 is easily deformable, under the pressure of the preheating liquid in the preheating box 1 and its own rebound, the flexible liquid-sealing bag 2 fits the probe surface more adaptably to the shape of the probe, so as to carry out comprehensive preheating, thereby avoiding uneven preheating and temperature difference, and effectively improving the preheating effect of the probe.

[0029] Specifically, a retaining sleeve 6 is fixed around the insertion / removal hole 11 on the outer surface of the preheating box 1. A rubber retaining sleeve 61 is fixed on the inner wall of the retaining sleeve 6. The rubber retaining sleeve 61 is press-fitted with the outer peripheral surface of the ultrasonic probe. Before inserting the ultrasonic probe into the flexible liquid-separating bag 2, the ultrasonic probe needs to be inserted through the retaining sleeve 6. The press-fitted retaining sleeve 6 and the outer peripheral wall of the probe create compression and friction, which allows the ultrasonic probe to be stuck in the retaining sleeve 6. This makes it easy for the probe to be kept on the preheating box 1 for preheating without manual handling. After preheating is complete, the probe can be pulled out directly. The structure is simple and the operation is convenient.

[0030] Specifically, water is used as the preheating liquid. Using water as the preheating liquid is low-cost and readily available, thereby reducing manufacturing costs. At the same time, water has good thermal conductivity, which helps to improve the efficiency of probe preheating. Furthermore, the water in the preheating box 1 is not full, leaving a certain space for the probe to be inserted into the flexible liquid-separating bag 2 for preheating. This avoids the pressure from the preheating box 1 being full of water, which would affect the smooth insertion of the probe.

[0031] Specifically, the heating device 4 uses an electric heating rod 41. Using the electric heating rod 41 as the heating element results in fast heating speed and good effect. At least four electric heating rods 41 are provided in the preheating box 1, and the electric heating rods 41 are evenly distributed around the flexible liquid-separating bag 2 to ensure that the heating source is evenly distributed in the preheating box 1, providing multi-point heating and better heating effect.

[0032] Specifically, a temperature controller 5 is provided on the top of the preheating box 1. The temperature sensing element of the temperature controller 5 extends into the preheating box 1. The temperature controller 5 is electrically connected to the electric heating rod 41. The heating temperature of the electric heating rod 41 can be easily adjusted through the temperature controller 5 to adapt to different weather and temperature changes, and to ensure that the probe can be preheated to the optimal temperature.

[0033] Specifically, a counterweight base 7 is fixed at the bottom of the preheating box 1. The counterweight base 7 provides counterweight at the bottom to ensure that the device is placed more stably. The bottom surface of the counterweight base 7 has anti-slip texture, which has an effective anti-slip effect.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
