Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a protective sleeve for an esophageal ultrasound probe to prevent aspiration and esophageal damage. Background Technology

[0002] Esophageal echocardiography involves inserting an ultrasound probe into the esophagus to examine the structure and function of the heart from behind, avoiding interference from the chest wall, lung air, and other factors. This improves the sensitivity and reliability of cardiovascular disease diagnosis and has had a significant impact on the diagnosis, treatment, and efficacy evaluation of cardiovascular diseases. It has become a commonly used tool for perioperative monitoring and assessment of various cardiovascular and critically ill patients.

[0003] However, complications of transesophageal echocardiography are not uncommon, occurring in up to 6.1% of cases. The most common complications are aspiration and esophageal injury (including perforation, tearing, hematoma, and bleeding). Aspiration occurs when gastric contents reflux into the pharynx and are accidentally inhaled into the trachea, causing aspiration pneumonia, which significantly prolongs hospital stays and increases the medical burden. Esophageal injury is caused by two mechanisms: "thermal damage" due to the heat generated by the probe, and pressure-related injury caused by prolonged forward bending of the probe tip, resulting in excessive pressure on the esophageal mucosa.

[0004] Therefore, there is an urgent need for a protective sleeve for the esophageal ultrasound probe to prevent aspiration and esophageal damage, in order to reduce the aforementioned complications. Utility Model Content

[0005] The purpose of this invention is to solve the problem of various complications in the existing technology of esophageal echocardiography based on ultrasound probes, and to provide an esophageal ultrasound probe protective sleeve to prevent aspiration and esophageal damage.

[0006] The technical solution of this utility model is as follows:

[0007] An esophageal ultrasound probe protective sleeve to prevent aspiration and esophageal damage includes a protective sleeve body, a mouthpiece, a water bladder, and a water bladder catheter.

[0008] One end of the protective sleeve body is connected to the mouthpiece, and the other end is fitted with a water bladder. The mouthpiece has a through hole that communicates with the cavity inside the protective sleeve body for installing an esophageal ultrasound probe in the cavity. The straight section of the water bladder catheter is installed on the protective sleeve body, and one end of it communicates with the water storage cavity of the water bladder, while the other end is connected to the water injection hole of the mouthpiece. The arc-shaped section is connected to the straight section through the water injection hole.

[0009] Preferably, a water bladder injection head is installed at the water injection end of the arc-shaped pipe section.

[0010] Preferably, it also includes a water metering device for injecting a set amount of water into the water bladder's injection head.

[0011] Preferably, the metering water supply device is a syringe or a measuring cylinder.

[0012] Preferably, the protective sleeve body is tubular and its length is 45-55cm.

[0013] Preferably, the inner diameter of the tubular protective sleeve body is larger than the diameter of the esophageal ultrasound probe.

[0014] Preferably, the difference between the inner diameter of the tubular protective sleeve body and the diameter of the esophageal ultrasound probe is 0.1-1 cm.

[0015] Preferably, the length of the water bladder attached to the protective sleeve body is 10-15cm.

[0016] Preferably, the protective sleeve body, the water bladder, and the water bladder conduit are all made of polyethylene film or latex.

[0017] Preferably, the mouthpiece is made of polyethylene.

[0018] According to the above technical solution, the esophageal ultrasound probe protective sleeve designed to prevent aspiration and esophageal injury incorporates a water-filled balloon fitted to one end of the main body of the protective sleeve. The water-filled balloon catheter is connected to the balloon via a mouthpiece and the main body of the protective sleeve. In practical applications, the water-filled balloon prevents aspiration by preventing the reflux of gastric contents; it reduces esophageal injury by lowering the temperature around the esophageal ultrasound probe and increasing the contact area with the esophagus; furthermore, the water-filled balloon has good acoustic transmission and reduces airflow between the probe and the esophagus, improving imaging quality. The mouthpiece prevents patients from biting and damaging the esophageal ultrasound probe. Attached Figure Description

[0032] The present invention will be described in detail below through embodiments, but the scope of protection of the present invention is not limited thereto.

[0033] Example 1

[0034] Adopting such Figure 1 The esophageal ultrasound probe protective sleeve shown is used for esophageal echocardiography examination. Specifically, the esophageal ultrasound probe protective sleeve includes a protective sleeve body 1, a mouthpiece 2, a water balloon 3, and a water balloon catheter 4.

[0035] One end of the protective sleeve body 1 is connected to the mouthpiece 2, and the other end is fitted with a water bladder 3. The mouthpiece 2 has a through hole communicating with the cavity inside the protective sleeve body 1 for installing the esophageal ultrasound probe 6 in the cavity. The straight tube section 41 of the water bladder catheter 4 is installed on the protective sleeve body 1, and one end of it is connected to the water storage cavity of the water bladder 3, and the other end is connected to the water injection hole of the mouthpiece 2. The arc-shaped tube section 42 is connected to the straight tube section 41 through the water injection hole. A water bladder injection head 5 is installed at the water injection end of the arc-shaped tube section 42. The protective sleeve body 1, the water bladder 3, and the water bladder catheter 4 are all made of polyethylene film. The mouthpiece 2 is made of polyethylene.

[0036] In actual use, the esophageal ultrasound probe 6 is inserted into the cavity of the protective sleeve body 1 through the through hole on the mouthpiece 2, and then inserted into the esophagus. After adjusting it to a suitable position, water is injected into the water bladder 3 through the water bladder injection head 5 to fill its water storage cavity, so that it can play its role.

[0037] Testing revealed that the esophageal ultrasound probe protective sleeve described in this invention, which prevents aspiration and esophageal damage, is superior to simple ultrasound probe solutions in the prior art by preventing the reflux of gastric contents to avoid aspiration; reducing esophageal damage by lowering the temperature around the esophageal ultrasound probe and increasing the contact area with the esophagus; and improving imaging quality by reducing the amount of air between the probe and the esophagus.

[0042] The implementation follows the same procedure as Embodiment 2, but with the difference that it also includes a metering water supply device for injecting a set amount of water into the water bladder injection head 5; the metering water supply device is a syringe without a needle.

[0043] Testing revealed that the esophageal ultrasound probe protective sleeve described in this invention, which prevents aspiration and esophageal damage, compared to the solution in Example 2, can further accurately inject a set amount of water into the water bladder according to application needs, thereby preventing the reflux of gastric contents and avoiding aspiration; reducing the temperature around the esophageal ultrasound probe, increasing the contact area with the esophagus and reducing esophageal damage; and reducing the air between the probe and the esophagus, thereby increasing the imaging effect.

A water-filled balloon is fitted to one end of the main body of the sleeve, and the balloon's tubing is connected to the balloon via a mouthpiece and the main body of the sleeve. In practical applications, this design prevents aspiration by preventing the reflux of gastric contents; reduces esophageal injury by lowering the temperature around the probe and increasing the contact area with the esophagus; and the water-filled balloon's good acoustic transmission reduces airflow between the probe and the esophagus, improving imaging quality. The mouthpiece also prevents patients from biting and damaging the esophageal ultrasound probe.
