The present disclosure relates to a tamponade device. The tamponade device includes a sheath member. The sheath member includes a hollow cavity defined along a length of the sheath member. The hollow cavity is configured to allow the insertion of a guidewire therein. The sheath member is configured to be positioned at a vascular access point of a subject over a guidewire deployed into the lumen of a blood vessel at the vascular access site. Further, the sheath member is configured with a predefined diametrical size that impedes the tamponade device from being deployed into the lumen of the blood vessel through the vascular access point, thereby positioning the sheath member at the vascular access point to occlude the vascular access point. By applying focal pressure or compression to the blood vessel directly at the vascular access site, hemostasis can be achieved using the tamponade device.

The front end of the flushing water channel is open to flush the bladder to be treated, and the rear end of the flushing water channel is closed. The inlet of the negative pressure suction mechanism can communicate with the rear end of the negative pressure suction catheter to drain the bladder to be treated. The probe of the endoscope mechanism can be inserted into the bladder irrigation catheter to take images inside the bladder to be treated. This utility model can achieve bedside visual negative pressure bladder irrigation, improving the treatment effect of bladder tamponade.

The present invention introduces a tampon with an integrated device designed for improved insertion, and removal, and leak prevention. The device comprises a flexible, nonpermeable wall, hollow to enable finger-assisted insertion and featuring a removal aid element attached to the bottom end of the wall for easy, hygienic extraction. Additionally, the wall is equipped with ridges that conform to the vaginal wall, enhancing the seal to prevent menstrual fluid leakage and block the absorption of external fluids. In other embodiments, a smoothed wall is offered. This invention eliminates the need for separate applicators, allows the device to compact for discrete portability, and significantly enhances user comfort and effectiveness in fluid management.

A vitreous humor filling agent for the posterior space in the eye comprises at least one structurally asymmetric fluoroether which is in a liquid state at room temperature or under surgical conditions and which can be converted to a gaseous state after injection into the eye as a result of its own intrinsic vapour pressure or by means of an external non-invasive method. In addition to the above requirements, such compounds also have a specific gravity of between 1.1 and 1.6 (the latter being an upper limit to prevent retinal toxicity), are immiscible with water, are non-flammable, have high ultrasound absorption, and are in a clear colourless form.

The application discloses a silicone oil filling simulation method and device for assisting treatment of retinal detachment, and the method comprises the following steps: constructing an eyeball wall model of a patient according to an elastic solid modeling method, and maintaining the incompressibility of the eyeball wall by adopting an implicit iterative correction pressure method based on the number density; for the scene of filling silicone oil in the intraocular cavity during surgery, the silicone oil is regarded as a high-viscosity incompressible Newton fluid, and the interaction between the silicone oil and the eyeball wall is simulated according to the coupling method between the fluid and the elastic solid; and the three-phase coupling environment composed of water, silicone oil and the eyeball wall generated by the aqueous humor entering the vitreous cavity after surgery is simulated, and the emulsification phenomenon of the water and the silicone oil occurring at the immiscible boundary is simulated. According to the technical scheme of the application, the eyeball wall is constructed according to the elastic solid modeling method, the filling environment is visualized, and the dynamic interaction generated by the filling is simulated through the volume incompressible model based on the number density, so that accurate quantitative analysis can be provided for the surgical treatment.

Multiple, separable disposal bags for tampons and pads are wrapped around a center roll. Each bag is connected to the next bag on the roll by a seam that includes a slit and a series of perforations separating connection points between the bags. A bag tail secures the first bag to itself by a bag tail that has an adhesive portion and a free, tab portion. The adhesive portion is attached to the first bag at a first zone and to a different portion of the first bag at a second zone. A user can pull on the free-tab portion of the bag tail to detach the second zone of the adhesive portion from the first bag. The first zone of the adhesive portion remains attached to the first bag after the first bag is detached from the subsequent bag at their seam.
