DE102005030262A1 - Mask for horse used for ergospirometric test, comprises rigid upper part and soft adjustable lower element - Google Patents

Abstract

The mask (1) has a rigid upper shell (2) to be attached to the area around the nostrils of the animal and to be secured with a head strap (8). Openings (3) for breathing and the accommodation of measuring devices are also included. A support element is swivel mounted to the front of the shell (2) and guided around the lower jaw of the horse. The soft, bag-like lower part (9) is joined to the upper part (2) with complementary strips of Velcro(RTM). The bridles (11) can be guided through openings (13) laterally positioned at the soft part (9).

Description

The The invention relates to a respiratory mask for ergospirometric examinations on large animals, in particular Horses, camels or similar animals, according to the preamble of claim 1.

International decreases the number of animals kept for leisure and sport purposes constantly to. These animals have additional to their material value also a very high ideal value. The Holders are increasingly calling for their animals an offer of medical services in the field of diagnostics and therapy, which meets the human medical standard equivalent.

Especially for ergospirometric Examinations on horses bridled with teeth (for example bridle, curb) are the ones to be considered Conditions difficult and not known technical solutions satisfactory. To express meaningful To obtain measurement results, the ergospirometric measurements on with the usual bridle ridden or driven animal. Creating the required device technology must also be easy and fast for animal psychological reasons, in order to avoid dangerous situations even in sensitive and spirited animals to avoid.

To the Carry out From ergospirometric studies it is known the respiratory flow as well the respiratory gas by means of sensors, such as volumetric flow sensors and sensors for the measurement of the carbon dioxide and oxygen content of the respiratory air analyze. For this purpose, the sensors are trained accordingly Respiratory masks and externally on the carcass arranged.

For ergospirometrische investigations on horses are well-known breathing masks for animals, as for example in the US 4,46,768 for inhalation purposes are not suitable.

From the DE 199 60 257 C1 is a mobile Ergospirometriesystem known for horses, the centerpiece of which is a cup-shaped breathing mask, which receives the sensors optimized aerodynamically in the region of the nostrils. The sealing takes place at the peripheral edge of the pot-shaped mask body by an inflatable tubular element. With this mask, it is not possible to ride or ride horses with the commonly used Gebißzäumung. In addition, due to the predetermined shape and size of the mask body, the measurement results falsifying dead spaces in the mask, the minimization of which is possible only by providing masks which are exactly adapted to the shape and size of the head or the insertion of filling bodies for filling the abnasal dead spaces. The fitting and insertion of packing in this generally closed mask and the subsequent subsequent application of the same is generally problematic because the packing could change its position and cause compressions of the soft tissues of the respiratory tract. The sealing of the mask against the horse's head by means of inflatable rubber hose carries the risk that the horse is hampered by possible pressure on nerves or blood vessels.

It is therefore an object of the invention, a species-specific breathing mask for the Ergospirometry in animals, especially horses, to create at the the above-mentioned disadvantages of known solutions are avoided.

These Task is a respiratory mask with the features of the claim 1 solved. advantageous From embodiments of the invention are specified in the subclaims.

a The main advantage of the invention is the possibility of ergospirometric Examinations during riding or driving. This is done by bridling the Horse with a bridle bit as well as the flexible part of the Breath mask protruding rein extensions reached. A flexible bag-like mask part guarantees a largely trouble-free Guided tour at an optimal seal. Further advantages of the invention exist Among other things, that a mask uncomplicated to different Head shapes and sizes are adjusted can, with the measurement results affecting dead spaces easy way to be optimally minimized using random packings can.

One embodiment The invention is illustrated in the figures and will be described below described in more detail.

It demonstrate:

2 the side view of a mask body

3 the front view of a mask body

4 the top view of a mask body

In the following embodiment, a respiratory mask according to the invention for horses will be described with reference to FIGS. As in the 2 to 4 shown, the breathing mask 1 a substantially half-shell-shaped rigid mask part 2 on. At the abnasal end of the mask part 2 are belt eyelets 7 for arranging fastening straps to be applied to the horse's head 8th educated. At the front lower end of the rigid mask part 2 is at a joint 5 the fixing bracket 4 arranged articulated and lockable. On the neck side, the fixation bar 4 a padded fixing bowl 6 for application on the lower jaw. In the area of the two nostrils of the horse are breathing holes 3 formed, which receive the assemblies not shown with breathing gas sensors. Below the breathing holes 3 runs around a part of a hook and loop fastener 10 , This is the one with the counterpart of the Velcro 10 provided bag-shaped flexible mask part 9 attached ( 1 ). The horse is with a bridle bit and reins 11 bridled. The reins extensions leading to the snaffle bit 12 be through the in the flexible mask part 9 incorporated reins 13 sealed passed.

The minimization of abnasal dead spaces in the applied breathing mask 1 takes place by arranging simultaneously cushioning packing in the rigid mask part 2 , The simple and from above laying on the rigid mask part 2 allows this in a very simple and variable way. At the nasal edge of the flexible mask part 9 is incorporated in the figures, not shown rubber or cord, through which an adequate sealing of the mask is ensured in this area.
