Abstract
A device for blood letting in bovines, which aids the correct position of a needle used for withdrawing the blood. The device may have a pair of flanges on an external surface to guide the needle. The device may fit over and protect a thumb or finger of the user. The flanges enable the device to dock in a intercoccygeal space in the tail. The device may have a void <B>B</B> through which part of the thumb or finger protrudes to enable tactile sensation.
Description
1 2452911 TITLE Apparatus for protection and helping the action of blood letting in bovines..
BACKGROUND:
Nowadays the most efficient way to blood sample cattle is via the "tail vein".The median coccygeal vein and artery run under the midline on the ventral aspect of the bovine tail. These vessels are accessible to venipuncture, but only in certain areas along the midline. As shown in Figi (ventral aspect of bovine tail) these accessible areas are marked A. These are voids on the boby of the tail and I will refer to them as intercoccygeal spaces. The main body of tail is composed of a number of coccygeal (caudal) vertebrae linked together. On gross examination these intercoccygeal spaces are elongated ovoid shaped depressions or indentations. They have defined borders and can easily be palpated and visualized. They run at intervals along the ventral aspect of the tail as shown in Figi part A. They are interrupted at intervals by elevations as represented by parts B in Fig 1. Withih these areas the coccygeal blood vessels run within the boby of the coccygeal vertebrae. As these are boney structures venipuncture is not possible at areas marked B in Fig 1.
Blood sampling bovines is a skilled job and does take some time to perfect. A blood sampler will lift the tail with one hand and use the other hand to take the sample, typically with a vacutainer and needle, as shown in Fig2. An inexperienced blood sampler will often be seen to elevate the bovine tail to a near vertical position in order to visualize the site to target for venipuncture. A proficient blood sampler will elevate the tail to little more than the horizontal position as shown in Fig2. The proficient blood sampler realizes that the more the tail is elevated the more the coccygeal vessels will be stretched and therefore constricted Blood samplers typically target the 2nd to the 4th intercoccygeal spaces as these tend to be the most fruitful Targeting the intercoccgeal spaces relies on vision as shown in Fig2. It follows the blood sampler will have to bend down every time he takes a sample If this has to be done several hundred times a day it soon becomes quite exhausting, especially if the animals have thick tails.
DESCRIPTION OF INVENTION:
This device is a protective covering or sleeve for a person's thumb or maybe finger It has a number of ridges (ribs) and projections (flanges) which serve different purposes. Fig3 is a lateral view of the device. As shown there are paired flanges that project from the main body of the device As shown in Fig3 they are flared initially but gradually taper and converge, but do not meet, to form ribs (ridges) on the ventral aspect of the device. This is shown in parts B andC Fig3.Fig4 is a plan view of the ventral aspect. Fig5 is a head on view of the device. The hatched areas demonstrate the extent of projection of the lateral flanges. As the device is symmetrical there are paired flanges on the other lateral side of the device. These too continue to the ventral side to form a set of paired ribs. This is shown in Fig4 and Fig5. As shown in Fig3 and Fig6 the lateral flanges act as needle guides. As shown they converge towards a small exit Fig3 part C This exit is designed to readily accept the bore of a blood letting needle. This exit is a short longitudinal aperture as shown as region A in Fig4. This narrow aperture is formed by the ventral ribs. As said the ventral ribs are a continuation of the lateral flanges. Each pair of ribs run and stop at a void or oval shaped hole in the device as shown in Fig4 part B. The paired ribs are symmetrical (Fig4) and sit proud from the main body of the device. This is shown in Fig3 part B and Fig5. The edges of the ventral ridges are a little convex as shown in the diagrams. The whole of the four ventral ribs act as a unified and sculptured body, the purpose of which is to be mutually be receptive to an intercoccygeal space As shown in Fig7 the ribbed structure of the device has been embedded in an intercoccygeal space on the tail. Fig6 demonstrates the position of the blood letting needle within the space formed by the lateral flanges.
An oval shaped void (Fig5) allows a small surface of palmer thumb to protrude slightly (Fig8). The operator will have sufficient tactile sensation to detect the borders of the intercoccygeal space. In conjunction with the ribs the operator can easily navigate, dock and embed the device in position. The device will lie directly over the coccygeal vessels. Its is an easy matter therefore to direct a blood taking needle through a set of lateral flanges, straight through the midline and into the lumen of the "tail vein".
As well as blood sampling this device can just as easily be use to administer substances intravenously.
The device is of simple nature. A single set of lateral flanges would suffice, but a pair of each means that the device is reversible. Bovine animals are generally presented to blood samplers in a line up a chute or crush. The blood sampler will be able to switch this device from one thumb to the other depending wether he is presented with left or right flanks.
Being of simple design an architecture it could be easily fabricated It is a one piece structure that could be manufactured using a die-cast method using a material such as plastic or metal. The drawings are of a crude nature and do not not illustrate the final refinements, but however the essential and fundamental principles are in place.
ADVANTAGES.
Saves Time: With minmal manipulation from the operator or disturbance to the animal a blood letting needle can be quickly and more reliably be directed into the lumen of the target blood vessel. Economy of time becomes very important when the herd size is very large Eliminates Skill: Blood sampling effeciently is a skill and takes time to perfect. This device requires no skill at all to direct and embed it to an intercoccygeal space, regardless of age,breed and for that matter the species of the animal Blood Sampler Remains Upright: A major advantage with so much emphasis on health and safety of employees. As said, a blood sampler may have to take several hundred samples per day. It follows they have to bend down just as many times to view the ventral tail. It is hardly surprising and not uncommom for seasoned blood samplers to complain of sore backs later in life.
Minimal Elevation Of The Tail: As shown in Fig9 this device allows the blood sampler success with minimal tail elevation. This is a more natural position of the tail, therefore the blood vessels will be "dilated' fully. A tail offers considerable resistance when elevated to the horizontal and even more to the vertical position. Lifting several hundred tails will leave the operator very tired, so it follows a proficient blood sampler is reluctant to lift a tail little more than the horizontal Coping With Animal Movements.
Cattle can be unpredictable and may move suddenly even when properly restrained. Once this device has been docked the operator wdl be able to cope with sudden movements. Without bending down the operator can still be fruitful as the target is still marked.
