Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary technology field, concretely is a kind of ultrasonic isolation sound transmission membrane for cavity. BACKGROUND

[0002] Ultrasonic examination is observed using the reflection of ultrasonic waves on the human body, generally referred to as US ultrasonic examination, which uses weak ultrasonic waves to irradiate the body and imageizes the reflected waves of the tissue. Hospitals usually use ultrasonic isolation sound transmission membranes on the outer cover of ultrasonic equipment when using ultrasonic equipment to examine patients.

[0003] Existing ultrasonic isolation sound transmission membranes for cavities are mostly improved by imitating condoms, mainly including a membrane body for wrapping an ultrasonic probe and a constriction body for tightening the membrane body. For example, Chinese patent CN210228187U (a new ultrasonic isolation sound transmission membrane for cavities) and Chinese patent CN211094236U (an ultrasonic isolation sound transmission membrane for cavities). The constriction body has good contraction elasticity. Then, during the process of sleeving the isolation sound transmission membrane on the ultrasonic probe, the moving stroke of the constriction body is from the front end of the ultrasonic probe to the end of the ultrasonic probe. The constriction body is always inwardly constricted during operation, which causes the constriction body to press the membrane body on the surface of the ultrasonic probe, making it inconvenient for the operator to sleeve and operate. Especially, the shapes of conventional ultrasonic probes are diverse, which also causes great difficulty in sleeving the ultrasonic isolation sound transmission membrane. SUMMARY

[0004] The utility model aims to provide an ultrasonic isolation sound transmission membrane for cavities to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an ultrasonic isolation sound transmission membrane for cavities, comprising a membrane body and a constriction body. The constriction body is arranged at the opening end of the membrane body and is fixedly connected with the membrane body. A supporting ring one is slidably sleeved on the outside of the membrane body. The part of the membrane body connected with the constriction body is wrapped on the supporting ring one together with the constriction body. The supporting ring one is a rigid ring, and the outer diameter of the supporting ring one is greater than the diameter of the thickest part of the ultrasonic probe.

[0006] Further, a supporting ring two is slidably sleeved on the inside of the membrane body. The supporting ring two is a rigid ring, and the inner diameter of the supporting ring two is greater than the diameter of the thickest part of the ultrasonic probe.

[0007] Further, the supporting ring one and the supporting ring two are made of ultra-high molecular weight polyethylene, and the outer diameter of the supporting ring two is smaller than the inner diameter of the supporting ring one.

[0008] Further, the membrane body and the constriction body are made of thermoplastic polyurethane elastomer rubber.

[0009] Furthermore, the outer wall of the collecting body is fixedly mounted with elastic pull rings, and four elastic pull rings are arranged in a circumferential array on the collecting body.

[0010] Furthermore, the elastic pull ring is made of the same material as the gathering body, and the elastic pull ring and the gathering body are connected together by a hot melt adhesive film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The retaining body itself is supported by the support ring, so that the retaining body will not stick tightly to the ultrasound probe during the process of putting on the membrane. This makes the process of putting on the membrane simple. After it is fully put on, the membrane is no longer wrapped around the support ring, and the support ring can be pulled out directly. The retaining body can then be gathered and closely adhered to the root of the ultrasound probe together with the membrane, further enhancing the isolation effect and preventing liquids or other substances from entering from the connection between the ultrasound probe and the membrane. This ensures that the sound-transmitting membrane can stably perform its isolation and sound transmission functions during cavity examination.

[0013] 2. The elastic pull rings facilitate the unfolding of the diaphragm and the surrounding structure, allowing it to be smoothly fitted over the ultrasound probe. Four elastic pull rings arranged in a circular array provide multiple points of application, enabling medical personnel to apply force evenly and precisely control the unfolding process of the ultrasound membrane. This ensures the membrane adheres tightly to the ultrasound probe. After the examination, medical personnel can easily remove the ultrasound-isolating membrane from the ultrasound probe and cavity by pulling the elastic pull rings. This ergonomic design reduces the difficulty and discomfort for medical personnel during operation and improves work efficiency. Attached Figure Description

[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] Embodiment one

[0022] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: an ultrasonic isolation sound-transmitting membrane for cavity, including membrane body 1, convergence body 2, convergence body 2 is arranged in the opening end of membrane body 1, and convergence body 2 is fixedly connected with membrane body 1, the outside of membrane body 1 is slidably equipped with support ring one 3, the part of membrane body 1 and convergence body 2 is connected with convergence body 2 and is wound on support ring one 3, support ring one 3 is rigid ring, and the outer diameter of support ring one 3 is greater than the diameter of the thickest place of ultrasonic probe, when ultrasonic isolation sound-transmitting membrane is not used, membrane body 1 and convergence body 2 are in natural state, support ring one 3 is equipped in the outside of membrane body 1, medical staff inserts ultrasonic probe from the opening end (the end where convergence body 2 is located) of membrane body 1, because convergence body 2 is fixedly connected with membrane body 1, and convergence body 2 can be wound on support ring one 3 with membrane body 1, this structure design makes membrane body 1 can slide in the outside of support ring one 3, facilitate the insertion of ultrasonic probe, and convergence body 2 is supported by support ring one 3, so that in the process of being equipped with membrane body 1, convergence body 2 does not tightly adhere to ultrasonic probe, so that the process of being equipped with membrane body 1 is simple, after being completely equipped, membrane body 1 is no longer wound on support ring one 3, can directly extract support ring one 3, and convergence body 2 can be converged, and is tightly adhered to the root of ultrasonic probe with membrane body 1, further enhance isolation effect, prevent liquid or other substances from entering from the connecting portion of ultrasonic probe and membrane body 1, ensure that sound-transmitting membrane can stably play the function of isolation and sound transmission in the process of cavity inspection;

[0023] The inside of membrane body 1 is slidably equipped with support ring two 4, support ring two 4 is rigid ring, and the inner diameter of support ring two 4 is greater than the diameter of the thickest place of ultrasonic probe, in the process of being equipped with membrane body 1, membrane body 1 can excessively adhere to probe, and support ring two 4 can be used as a spacing structure in the inside of membrane body 1, so that the space between membrane body 1 and ultrasonic probe is kept appropriate, avoid that membrane body 1 excessively adheres to probe, and then ensure that membrane body 1 is excessively stretched and broken under the double action of traction and friction between membrane body 1 and ultrasonic probe in the process of being equipped, after being equipped with membrane body 1, support ring two 4 can be slid to be taken out from the inside of membrane body 1, and convergence body 2 is not hindered to converge membrane body 1;

[0024] The support ring one 3 and the support ring two 4 are made of ultra-high molecular weight polyethylene. The friction coefficient of the ultra-high molecular weight polyethylene itself is very low, and it has the characteristics of self-lubrication. When the support ring one 3 and the support ring two 4 slide relative to the film body 1, the friction with the film body 1 is small, and the film body 1 will not be excessively pulled and deformed. The ultra-high molecular weight polyethylene has excellent wear resistance and can withstand such frequent friction, reducing the wear of the surface of the support ring one 3 and the support ring two 4, thereby prolonging the service life of the support ring one 3 and the support ring two 4. Although the ultra-high molecular weight polyethylene is a plastic, it has high strength and rigidity, and can effectively support the film body 1. The ultra-high molecular weight polyethylene has excellent fatigue resistance and can withstand repeated stress changes without easily cracking or damaging, ensuring that the support ring one 3 and the support ring two 4 have stable performance during long-term use. The outer diameter of the support ring two 4 is smaller than the inner diameter of the support ring one 3, so that the support ring two 4 can pass through the support ring one 3. That is, the film body 1, the constriction body 2, the support ring one 3, and the support ring two 4 can be rolled together when the ultrasonic isolation and transmission film is not in use.

[0025] The film body 1 and the constriction body 2 are made of thermoplastic polyurethane elastomer rubber. The thermoplastic polyurethane elastomer rubber (TPU) has excellent elasticity. When the ultrasonic probe is inserted into the film body 1, the TPU material can elastically deform according to the shape of the probe and tightly fit the surface of the probe. The acoustic properties of the TPU material are good, and it can effectively transmit ultrasonic waves to ensure accurate transmission of signals during ultrasonic examination. The molecular structure and physical properties inside the TPU material make the attenuation of ultrasonic waves relatively low when penetrating the film body 1, thereby providing clear and accurate images for ultrasonic examination. In the cavity environment, there are various body fluids such as gastric juice, intestinal juice, and bile. These body fluids have different pH and chemical composition. The TPU material has good chemical stability and can resist corrosion from these body fluids. It will not undergo chemical changes such as degradation and swelling when in contact with the body fluids, thereby ensuring the integrity and functional stability of the film body 1 and the constriction body 2 during use.

[0026] Working principle: in use, medical staff inserts the ultrasonic probe from the opening end of the membrane body 1 (the end where the converging body 2 is located), since the converging body 2 is fixedly connected with the membrane body 1, and the converging body 2 can be wound on the supporting ring one 3 together with the membrane body 1, this structure design enables the membrane body 1 to slide outside the supporting ring one 3, facilitating the insertion of the ultrasonic probe, while the converging body 2 is supported by the supporting ring one 3, so that in the process of putting on the membrane body 1, the converging body 2 does not tightly adhere to the ultrasonic probe, so that the process of putting on the membrane body 1 is simple, and after being completely put on, the membrane body 1 is no longer wound on the supporting ring one 3, and the supporting ring one 3 can be directly pulled out, while the converging body 2 can be converged, and tightly adheres to the root of the ultrasonic probe together with the membrane body 1, further enhancing the isolation effect, preventing liquid or other substances from entering from the connection between the ultrasonic probe and the membrane body 1, and ensuring that the sound transmission membrane can stably play the functions of isolation and sound transmission during the cavity examination process.

[0027] Embodiment two

[0028] Please refer to Figure 5 The utility model provides a technical scheme: an ultrasonic isolation sound transmission membrane for a cavity, comprising a membrane body 1 and a converging body 2, the converging body 2 is arranged at the opening end of the membrane body 1, and the converging body 2 is fixedly connected with the membrane body 1, a supporting ring one 3 is slidably arranged outside the membrane body 1, the part of the membrane body 1 connected with the converging body 2 is wound on the supporting ring one 3 together with the converging body 2, the supporting ring one 3 is a rigid ring, and the outer diameter of the supporting ring one 3 is greater than the diameter of the thickest part of the ultrasonic probe.

[0029] The membrane body 1 and the converging body 2 are made of thermoplastic polyurethane elastomer rubber.

[0030] The outer wall of the converging body 2 is fixedly provided with four elastic tabs 5 which are circumferentially arranged on the converging body 2, the elastic tabs 5 are stretched to facilitate the unfolding of the converging body 2 and the membrane body 1, so that the ultrasonic isolation sound transmission membrane can be smoothly put on the ultrasonic probe, the circumferential arrangement of the four elastic tabs 5 provides multiple force application points, so that medical staff can apply force uniformly to more accurately control the unfolding process of the sound transmission membrane, and ensure that the membrane body 1 tightly adheres to the ultrasonic probe, after the examination is completed, medical staff can easily take out the ultrasonic isolation sound transmission membrane from the ultrasonic probe and the cavity by pulling the elastic tabs 5, this design conforms to the principle of ergonomics, reduces the difficulty and discomfort of medical staff in the operation process, and improves the work efficiency.

[0031] The material of the elastic pull ring 5 is the same as that of the collection body 2, so that the elastic pull ring 5 and the collection body 2 can be well matched in key performances such as elasticity, flexibility, chemical stability and biocompatibility, which ensures that the elastic pull ring 5 and the collection body 2 work as a whole during use, and can provide stable performance for the ultrasonic isolation and sound transmission film. The elastic pull ring 5 and the collection body 2 are connected together through a hot melt adhesive film, and the hot melt adhesive film can firmly connect the elastic pull ring 5 and the collection body 2 together after heating. This connection mode can provide sufficient connection strength, and ensure that the elastic pull ring 5 will not easily fall off from the collection body 2 during use. When the medical staff stretches the elastic pull ring 5 to install, adjust or take out the sound transmission film, the hot melt adhesive film connection can bear the corresponding tension, and ensure the integrity of the structure.

[0032] Working principle: When using, when using the ultrasonic isolation and sound transmission film, the medical staff can conveniently unfold the collection body 2 and the film body 1 by stretching the elastic pull ring 5, so that they can be smoothly sleeved outside the ultrasonic probe. When taking out, the ultrasonic isolation and sound transmission film can be easily taken out from the ultrasonic probe and the cavity by pulling the elastic pull ring 5.
