Description

Technical Field

[0001] This utility model relates to the technical field of transrectal examination instruments, specifically to a double-layer protective sleeve for a transrectal ultrasound probe. Background Technology

[0002] When performing a transrectal examination, an ultrasound probe is generally required. The effective detection area of ​​the ultrasound probe is usually distributed in a T-shape. During the examination, a large amount of medical coupling agent is usually applied to the entire probe, and a protective cover, such as a silicone condom, is then placed over the probe coated with medical coupling agent.

[0003] The medical coupling agent is filled in the gap between the protective sleeve and the probe. The protective sleeve only prevents the coupling agent from leaking out; it does not confine the coupling agent between the protective sleeve and the probe to the effective detection area of ​​the probe. Instead, the coupling agent is distributed in a dispersed manner and easily spreads outward under external force. Since the probe is inserted into the patient's anus, the anal sphincter muscles are in a contracted state when stimulated. The coupling agent attached to the probe inside the protective sleeve is easily squeezed. When there is less coupling agent on the probe, the squeezed coupling agent tends to spread outward to the periphery of the T-shaped effective area, that is, the coupling agent originally attached to the T-shaped effective area of ​​the probe and the protective sleeve gradually decreases. The reduction of coupling agent in the T-shaped effective area of ​​the probe will lead to unclear ultrasound images. When too much coupling agent is placed in the protective sleeve, it will cause the protective sleeve to be subjected to excessive outward squeezing force of the coupling agent, which may cause the protective sleeve to break. At the same time, applying too much medical coupling agent will also waste medical resources.

[0004] In summary, the existing protective sleeves only prevent the medical coupling agent from leaking out, but cannot confine the medical coupling agent placed between the protective sleeve and the probe to the effective detection area of ​​the probe. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer protective sleeve for transrectal ultrasound probes to solve the technical problems in existing devices.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A double-layer protective sleeve for a transrectal ultrasound probe includes an outer sleeve with one open end and one closed end, and a hollow inner sleeve. The inner sleeve is installed on the closed end of the outer sleeve and is fitted onto the probe. A T-shaped flow channel for filling with coupling agent is formed in the interlayer between the inner sleeve and the outer sleeve, so that the coupling agent filled in the T-shaped flow channel accurately covers the effective area of ​​the probe.

[0008] The inner wall of the inner sleeve is provided with an injection port that communicates with the T-shaped flow channel. A rubber seat is provided on one side of the T-shaped flow channel for the injection port. The diameter of the rubber seat is larger than the diameter of the injection port. A rubber strip is provided on the side of the rubber seat facing the injection port to drive the rubber seat to fit against the injection port, so that after the coupling agent is filled, the T-shaped flow channel can be automatically closed by external pressure.

[0009] As a preferred embodiment of this utility model, the outer wall of the inner sleeve is provided with a vertical groove along its own length direction, and the top of the inner sleeve is provided with a ring groove along its own outer wall periphery. The ring groove is perpendicularly connected to the vertical groove, and the outer sleeve can close the vertical groove and the ring groove to form a T-shaped flow channel that can be adapted to the shape of the probe.

[0010] In a preferred embodiment of this utility model, the length of the inner sleeve is less than the length of the outer sleeve.

[0011] As a preferred embodiment of this utility model, both the inner sleeve and the outer sleeve are made of transparent rubber material.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The T-shaped flow channel in this device matches the shape of the probe, and the protective sleeve restricts the flow of medical coupling agent, ensuring that an appropriate amount of medical coupling agent covers the effective detection area of ​​the probe. When using it, there is no need to coat the entire probe with coupling agent; it is only necessary to fill the T-shaped flow channel with coupling agent. This ensures that there is enough coupling agent in the effective imaging part of the probe, which reduces the actual amount of coupling agent used and reduces departmental costs.

[0014] At the same time, the rubber round seat and the rubber strip work together to form an automatic closing mechanism, which can not only satisfy the filling of coupling agent at the injection port, but also automatically close the injection port after the coupling agent is filled. Moreover, after closing, the injection port is sealed even more tightly under the action of external extrusion pressure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1 to 3 As shown, a double-layer protective sleeve for a transrectal ultrasound probe includes an outer sleeve 1 with one end open and the other closed, and a hollow inner sleeve 2. The inner sleeve 2 is installed on the closed end of the outer sleeve 1 and is fitted onto the probe. A T-shaped flow channel 3 is formed in the interlayer between the inner sleeve 2 and the outer sleeve 1, which can be filled with coupling agent so that the coupling agent filled in the T-shaped flow channel 3 accurately covers the effective area of ​​the probe.

[0024] Specifically, such as Figures 1 to 3 As shown, the outer wall of the inner sleeve 2 has a vertical groove 4 along its own length direction, and the top of the inner sleeve 2 has a ring groove 5 along its own outer wall periphery. The ring groove 5 is vertically connected to the vertical groove 4. The outer sleeve 1 can close the vertical groove 4 and the ring groove 5 to form a T-shaped flow channel 3 that can be adapted to the shape of the probe.

[0025] The T-shaped flow channel matches the shape of the probe, so there is no need to coat the entire probe with coupling agent during use. Only the coupling agent needs to be filled into the T-shaped flow channel. This ensures that there is enough coupling agent in the effective imaging part of the probe, which reduces the actual amount of coupling agent used and reduces departmental costs.

[0026] The inner sleeve 2 has an injection port 7 on its inner side wall that communicates with the T-shaped flow channel 3. A rubber seat 6 is provided on one side of the injection port 7 and the diameter of the rubber seat 6 is larger than the diameter of the injection port 7. A rubber strip 8 is provided on the side of the rubber seat 6 facing the injection port 7 to drive the rubber seat 6 to fit against the injection port 7, so that after the coupling agent is filled, the T-shaped flow channel 3 can be automatically closed by external pressure.

[0027] The rubber round base and the rubber strip work together to form an automatically closing sealing mechanism. This mechanism not only allows for the filling of the injection port with coupling agent, but also automatically closes the injection port after the coupling agent is filled. Moreover, under external pressure, the injection port seals even more tightly after closing.

[0028] like Figure 1 and Figure 2 As shown, the length of the inner sleeve 2 is less than the length of the outer sleeve 1, which ensures that the inner sleeve 2 completely covers the probe and reduces material waste. Furthermore, both the inner sleeve 2 and the outer sleeve 1 are made of transparent rubber.

[0029] This ensures the flexibility of the entire protective sleeve and allows for clear observation of the position of the T-shaped flow channel 3, facilitating precise contact between the T-shaped flow channel 3 and the probe. This is mainly because the color of the effective area in the probe is different from the color of other areas of the probe. As long as the T-shaped flow channel 3 filled with coupling agent is aligned with the colored area of ​​the probe during installation, it is sufficient.

[0030] The protective sleeve can be a disposable item, in which the coupling agent is filled and sealed before the protective sleeve is manufactured, or it can be filled separately during subsequent use. For ease of use, this application can be designed for subsequent addition, that is, the protective sleeve is provided with an injection port 7 for filling the T-shaped flow channel 3 with coupling agent.

[0031] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
