Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary treatment of dysphagia, and in particular relates to a swallowing balloon dilator and a dilation balloon and a dilation control component thereof. Background Art

[0002] Cricopharyngeal muscle balloon dilatation is currently a commonly used interventional technology for the treatment of dysphagia. Balloon rubber tube dilatation can reduce the resting pressure of the upper esophageal sphincter, increase its relaxation time and degree, and significantly relieve dysphagia. It normalizes the tension, contractility and elasticity of the cricopharyngeal muscle through mechanical dilatation to solve the swallowing disorder caused by cricopharyngeal muscle atony. It is characterized by simple operation and little damage. The dilatation treatment effect is achieved by stretching and stimulating the brainstem reflex arc and the cerebral cortex control system. This technology is quite safe and reliable, low-cost, simple to operate, and has high patient compliance.

[0003] For dysphagia caused by cricopharyngeal atony, a catheter with a balloon is often used for dilation treatment. At present, urinary catheters are often used for stimulation, and in clinical practice, liquid infusion with a syringe is more often used to inflate the balloon for stimulation. For example, CN214970998U and others disclose swallowing stimulation balloons, but they lack matching balloon dilators to achieve stable control of balloon expansion and contraction.

DETAILED DESCRIPTION

[0031] The utility model is further described below in conjunction with the accompanying drawings.

[0032] Swallowing a balloon dilator, such as Figure 1 As shown in , it includes an expansion control component 200, and / or the expansion balloon 100. In this section, at least one of the expansion control component 200 and the expansion balloon 100 is one of the components described in detail below. Specifically, it can be:

[0033] I) A swallowing balloon dilator includes a combination of any dilation control assembly 200 of the present disclosure and any dilation balloon 100 of the present disclosure;

[0034] II) A swallowing balloon dilator includes a combination of any dilation control assembly 200 disclosed in the present disclosure and any existing dilation balloon, and the specific existing dilation balloon may be a syringe, an ear cleaning bulb, etc.;

[0035] III) The swallowing balloon dilator includes a combination of any dilation balloon 100 disclosed in the present disclosure and any existing dilation control component, and the specific existing dilation control component may be a urinary catheter with a balloon, etc.;

[0036] IV) The swallowing balloon dilator includes any expansion control component 200 disclosed in the present disclosure. In this case, the claim only relates to the expansion control component 200. At this time, the swallowing balloon dilator can be interpreted as the expansion control component 200, and the expansion balloon 100 adapted thereto is not considered;

[0037] V) The swallowing balloon dilator includes any one of the dilation balloons 100 disclosed in the present disclosure. In this case, the claims only relate to the dilation balloon 100. At this time, the swallowing balloon dilator can be interpreted as the dilation balloon 100, and the dilation control component 200 adapted thereto is not considered.

[0038] Generally speaking, fluid is infused into the squeezing balloon 210, and the squeezing balloon 210 is connected to the expansion control component 200. The fluid can better transmit pressure to expand the end balloon of the expansion balloon 100. The fluid can specifically be a liquid such as water or a fluid gel. Of course, in some cases, gas can also be used. Compared with gas, water has stronger resistance to compression, which can better expand the balloon and maintain support.

[0039] Among them, when the squeezing balloon 210 is squeezed, the fluid in the squeezing balloon 210 can enter the expansion balloon tube and expand the end balloon; when the squeezing balloon 210 is not squeezed, it has a tendency to restore its original shape and the fluid in the expansion balloon tube can return to the squeezing balloon 210 through the liquid flow valve 220. That is, when the squeezing balloon 210 is squeezed to reduce the effective volume of its inner cavity, the fluid enters the expansion balloon, and when no external force is applied to the squeezing balloon 210, the squeezing balloon 210 can restore its original shape and allow the liquid in the expansion balloon to flow back into the expansion balloon, and cause the balloon of the expansion balloon to shrink. Of course, it is not strictly required that all the fluid in the expansion balloon flow back into the squeezing balloon 210, as long as the balloon of the expansion balloon can shrink. The control of the perfusion amount of the expansion balloon 100 can also be achieved by controlling the deformation of the squeezing balloon 210, and when necessary, it can be as follows Fig.10 As shown in the figure, the squeezing balloon 210 is set to a transparent material, and a scale is set on its surface. After squeezing, the volume of the fluid pressed into the expansion balloon 100 can be clearly observed by observing the remaining amount of fluid (such as water), thereby achieving precise control; the specific marking method can be set according to clinical or actual needs, and will not be elaborated here.

[0040] As for the aforementioned expansion control component and expansion balloon, the following solutions can be specifically adopted for both.

[0041] Expansion control components, such as Figures 2 to 6 Shown, including

[0042] Extrusion balloon 210, which has a mounting through hole,

[0043] The liquid flow valve 220 is located in the squeezing balloon 210, and has a liquid through hole 222 on its side wall, and an opening at one end is connected to the mounting through hole, and has a pressure equalizing hole 221 at the other end.

[0044] The valve core 230 is slidably disposed in the liquid flow valve 220, and has a liquid flow channel 233 at one end thereof close to the installation through hole, and a liquid outlet channel 231 and a liquid return channel 232 are opened on the side wall thereof, both of which are communicated with the liquid flow channel 233, and the liquid outlet channel 231 is located between the liquid return channel 232 and the pressure equalizing hole 221, so as to ensure that the liquid return channel 232 passes through the liquid through hole 222 first when the valve core 230 moves toward the installation through hole;

[0045] The valve core 230 has a tendency to keep the liquid return channel 232 in communication with the liquid through hole 222 in the liquid flow valve 220 (eg Figure 2 , 5 ), when the squeezing balloon 210 is pressed, it can tend to slide the valve core 230 and make the liquid outlet channel 231 communicate with the liquid through hole 222 (such as Figure 3 , 4 ).

[0046] The inner diameter of the liquid outlet channel 231 is larger than the inner diameter of the liquid return channel 232. Alternatively, the inner diameter of the liquid flow channel 233 may be larger than or equal to the inner diameter of the liquid outlet channel 231. Alternatively, the inner diameter of the liquid through hole 222 may be larger than the inner diameter of the liquid return channel 232. It should be noted that the inner diameter described in this article may be the inner diameter of a single channel or the sum of the inner diameters of multiple channels. With this design, it can be ensured that the fluid can pass through the liquid outlet channel 231 more smoothly, but the resistance when the fluid passes through the liquid return channel 232 is relatively large. When the resistance of the fluid passing through the liquid return channel 232 is large, equal pressure is also applied to the valve core 230. Under the action of the fluid pressure, the valve core 230 will move toward the mounting through hole, and further make the liquid return channel 232 as Figure 3 The valve core 230 is blocked in the middle, and the valve core 230 moves toward the installation through hole more smoothly. Figure 4As shown in the figure, the outlet channel 231 and the liquid hole 222 are connected. Since the fluid passes through the liquid hole 222 more smoothly, when the extrusion pressure of the extrusion balloon 210 is kept stable, the pressure of the valve core 230 moving to the left is balanced with the force of moving to the right. At this time, the fluid can flow out from the liquid flow channel 233 stably and quickly through the liquid hole 222 and the outlet channel 231 and enter the expansion balloon. The inner diameter of the pressure-equalizing hole 221 is larger than the inner diameter of any of the outlet channel 231, the return liquid channel 232, and the liquid hole 222. In this way, it can be better ensured that when the extrusion balloon 210 is pressurized, especially when it is squeezed quickly, it is easier for the valve core 230 to move to the installation through hole. Since the diameter of the return liquid channel 232 is small, when the extrusion balloon 210 is not squeezed by external force, the reflux speed of the fluid from the expansion balloon to the extrusion balloon 210 is slow, and the bulging state of the expansion balloon can be maintained for a longer time.

[0047] The valve core 230 is made of rubber material, which is similar to a syringe piston, but its sliding resistance can be set to be smaller, so that the valve core 230 can slide easily; a rebound member 240 is provided between the valve core 230 and the liquid flow valve 220, and the rebound member 240 makes the return liquid channel 232 have a tendency to maintain communication with the liquid through hole 222. By providing the rebound member 240, the valve core 230 can be moved to the right more stably. At the same time, when the squeezing balloon 210 returns to its original shape, it also has a certain inducing effect on the rightward movement of the valve core 230 during its recovery process. Specifically, when the squeezing balloon 210 returns to its original shape, the internal pressure decreases, and the valve core 230 moves toward the end of the pressure equalizing hole 221.

[0048] In summary, when the squeezing balloon 210 is squeezed, the valve core 230 can move toward the installation through hole; when the squeezing of the squeezing balloon 210 is removed, the valve core 230 slides to the liquid return channel 232 and communicates with the liquid through hole 222.

[0049] Dilatation balloon, such as Figure 7 As shown in

[0050] The tube body 110 has an infusion cavity 111. The front end side wall of the tube body 110 has a tube body through hole 112. The rear end is used to connect the expansion control component. The tube body 110 can be made of rubber or the same material as common medical flexible tubes.

[0051] The elastic balloon 120 is located at the front end of the tube body 110, and its inner cavity is communicated with the tube body through hole 112;

[0052] The elastic balloon 120 at least includes a first elastic balloon 120a and a second elastic balloon 120b which are arranged in sequence from the end to the tail of the tube body 110. The deformation degree of each balloon is not understood, so that the shape of the pharyngeal cavity can be better adapted to the shape of the pharyngeal cavity, such as forming an integral balloon with inconsistent upper and lower outer diameters, which can better fit the inner wall of the pharyngeal cavity and stimulate it. When fluid reflux is required, the elastic elastic balloon 120 will also shrink under the action of elastic force, and at this time, pressure will be applied to the fluid to make it reflux, which is also conducive to fluid reflux and the reduction of the outer diameter of the elastic balloon 120.

[0053] The deformation degree of the first elastic balloon 120a is greater than the deformation degree of the second elastic balloon 120b.

[0054] In some other cases, in order to better ensure the safety of balloon stimulation, a ventilator can be set; in an emergency, the expansion controller can be directly disassembled to quickly relieve the pressure of the expansion balloon and shrink it. Figure 8 As shown in , the tube body 110 also has a ventilation tube, one end of which passes through the front end wall of the tube body 110, and the other end passes through the rear end wall of the tube body 110; the rear end of the tube body 110 is detachably connected to the expansion control component.
