Description

瘤胃臌气穿刺针 Rumen needle tympany

技术领域 FIELD

[0001] 本发明涉及兽医医疗器械的技术领域,尤其涉及瘤胃臌气穿刺针。 [0001] Technical Field The present invention relates to veterinary medical devices, particularly to a rumen tympany needle.

背景技术 Background technique

[0002] 瘤胃臌气是反刍动物特有的一种消化系统疾病,由病程可分为急性瘤胃臌气和慢性瘤胃臌气。 [0002] rumen tympany a specific ruminant digestive diseases, the course can be divided into acute and chronic rumen tympany tympany rumen. 由于慢性瘤胃臌气并不是独立的疾病,而是见于食管、前胃、真胃以及肠道慢性疾病经过中的一种综合征,治疗原则主要在于除去原发病,对症治疗多无效果,所以,瘤胃臌气通常是指急性瘤胃臌气。 Tympany rumen due to chronic diseases are not independent, but found in the esophagus, the stomach before, abomasum and chronic intestinal disease is through a syndrome, is to remove the main principles of treatment of the primary disease, symptomatic treatment effect is no more, so , generally refers to rumen tympany tympany acute rumen.

[0003] 急性瘤胃臌气是由于前胃神经反应性降低,收缩力减弱,采食的易发酵饲料在瘤胃内菌群作用下迅速酵解,产生大量气体(泡沫),而引起的瘤胃和网胃急剧臌胀。 [0003] Acute rumen tympany neural response is due to reduced stomach before, contractility, feed intake of readily fermentable rapid glycolysis microflora in the rumen, produce large amounts of gas (foam), and the network caused by rumen sharp stomach distention. 按照病性,急性瘤胃臌气还可以进一步分为泡沫性臌气和气体性臌气。 According to disease, acute rumen tympany may be further divided into gas and lather properties tympany tympany. 急性瘤胃臌气多发于牛和绵羊,山羊少见。 Acute rumen tympany mainly in cattle and sheep, goats rare. 在我国南方耕牛中的发病率,约占前胃疾病的15%_20%。 The incidence of cattle in the south of the country, accounting for 15% _20% before gastric disorders. 夏季放牧的牛羊可能成群发生,病死率可达30%,舍饲的牛羊如管理不当,亦会群发,死亡率也较高。 Summer grazing cattle and sheep flocks may occur, mortality up to 30%, such as cattle and sheep feeding of mismanagement, will be mass mortality is higher.

[0004] 瘤胃形同发酵罐,采食的饲草、饲料在其酵解和运化过程中所产生的气体,主要是二氧化碳和甲烷,还有少量氢、氧、氮和硫等。 [0004] Rumen tantamount fermenter, feed gas forage, fodder glycolysis and its generated during transportation of mainly carbon dioxide and methane, as well as a small amount of hydrogen, oxygen, nitrogen and sulfur. 这些气体,除部分在内容物表面形成气帽外,大多通过反刍和嗳气排出,或随同瘤胃内容物运转至真胃和小肠吸收,从而保持产气与排气的相对平衡。 These gases, in addition to forming part of the gas content in the surface of the outer cap, and belching discharged mostly through rumination, or with the contents of the rumen and abomasum operation to intestinal absorption, so as to maintain the relative balance of the exhaust gas. 但病理状态下,采食的易发酵饲料,产生大量的气体,既不能通过嗳气排出,又不能随同内容物由胃肠道吸收和排除,因而导致瘤胃急性扩张和臌气。 However, under pathological conditions, easy feeding fermented feed, a large amount of gas by eructation neither discharged along with the content can not exclude from the gastrointestinal tract and absorbed, resulting in expansion and tympany acute rumen.

[0005] 泡沫性瘤胃臌气的发生机制较为复杂。 [0005] The mechanism of foam tympany rumen is complex. 泡沫的形成,主要决定于瘤胃液的表面张力、粘稠度及泡沫表面的吸附性能这三种胶体化学因素。 Foam formation, mainly depends on the tumor adsorption properties of the surface tension of the gastric juice, the viscosity of the foam surface and colloidal chemistry of these three factors. 易发酵的饲料,特别是豆科植物,含多量的蛋白质、皂苷、果胶等物质,可产生气泡。 Readily fermentable feed, in particular legumes, contain large amounts of protein, saponin and pectin substances, air bubbles may be generated. 其中核糖体(rRNA) 18S更具有生成泡沫的特性。 Wherein the ribosomal (rRNA) 18S more foam generation characteristics. 果胶、唾液中的粘蛋白和细菌的多糖可增高瘤胃液的粘稠度。 Pectin, mucin saliva and bacterial polysaccharide viscosity can be increased tumor gastric juice. 瘤胃内容物发酵过程中的所产生的有机酸,热别是柠檬酸、丙二酸、琥珀酸等非挥发性酸类,可使瘤胃液的PH下降。 Rumen contents of organic acids in the fermentation process of the generated heat is not citric acid, malonic acid, succinic acid and other non-volatile, can decrease PH rumen fluid. 当pH降至6.0-5.2时,泡沫的稳定性较高,不能逸出,以致阻塞贲门,嗳气停止,而于短时间内发展成为泡沫型臌气。 When the pH is lowered to 6.0-5.2, high stability of the foam, can not escape, resulting in cardiac obstruction, belching stops, and in a short time developed into a foam type tympany. 气体性瘤胃臌气的发生,主要起因于瘤胃内碳酸氢盐、发酵过程产生的大量游离二氧化碳和甲烷以及饲料中所含氰苷和脱氢黄体酮化合物(类似维生素P),降低了前胃神经的兴奋性,并对瘤胃收缩有抑制作用。 Tympany rumen gas occurs, mainly due to the rumen bicarbonates, cyanogenic glycosides and progesterone dehydrogenated compound (similar to vitamin P) and the large number of free feed carbon dioxide and methane contained in the fermentation process produces reduced nerve forestomach excitability, and rumen contraction was inhibited.

[0006] 在瘤胃臌气的病情发展中,由于瘤胃壁过度扩张,腹内压升高,胸腔负压降低,使呼吸与血液循环发生障碍。 [0006] In the rumen tympany disease development, since the excessive expansion of the rumen wall, intra-abdominal pressure, the negative pressure decreases chest, breathing and blood circulation disorders. 瘤胃内腐败、酵解产物刺激瘤胃壁发生痉挛性收缩,而呈疼痛不安现象。 Rumen corruption, glycolysis product rumen wall spasm stimulated contraction, pain and anxiety was phenomenon. 疾病末期,瘤胃壁张力完全丧失,气体排出更为困难,血液中二氧化碳显著升高,碱储下降,可见静脉怒张,呼吸困难,发生窒息和心脏麻痹并在数小时内死亡。 Disease stage, tension is completely lost the rumen wall, the discharge gas is more difficult, a significant increase of carbon dioxide in the blood, decreased alkaline reserve, visible venous engorgement, dyspnea, suffocation, and heart attack and death within a few hours.

[0007] 瘤胃臌气的治疗原则在于排气消胀,理气止酵,强心输液,健胃消导。 [0007] The principle of treatment is that the exhaust rumen tympany Xiaozhang, qi stop fermentation, cardiac infusion, stomach consumer guide. 治疗过程中一般使用瘤胃穿刺针对瘤胃穿刺放气,同时内服或通过套管穿刺针向瘤胃内灌注止酵消导药物配合治疗。 Course of treatment is generally used for gassing rumen rumen puncture the puncture, while retaining internal or infusion into the rumen cannula through a puncture needle yeast eliminate lead drugs with treatment. 但是,在实际的瘤胃穿刺放气过程中,传统的瘤胃穿刺针存在诸多不便,下面以牛为例,一一说明。 However, in the actual rumen puncture during deflation, the conventional puncture needle, there are many inconveniences rumen, cattle below as an example, setting them. 第一,对于泡沫型臌气病牛,穿刺针行瘤胃穿刺后,由于大量气泡及气泡上食糜的存在,放气口必然堵塞,只能断断续续地排出少量气体,若拔出穿刺针清理再次进行穿刺放气,不但放气效果仍不理想,还会徒增病牛疼痛和感染风险;第二,对于由于食道阻塞、痉挛和麻痹等食道疾病继发的瘤胃臌气,以及泡沫性臌气阻塞贲门的情况,止酵消导药物无法口服或灌胃,只能由瘤胃穿刺套管针灌注,这就导致了穿刺放气和灌注消导药物不能同时进行,会延误急性臌气病牛的救治时间,也会影响救治效果;第三,即使对于单纯的气体性瘤胃臌气,一般病牛不会配合口服或导管灌胃药物,仍需要通过穿刺针灌注止酵消导药物,而传统的穿刺针只有一个针孔(即放气孔)可供灌注使用,不仅灌注速度慢,且由于是单点灌注,止酵消导或健胃药物只能在硕大的瘤 First, for the foam type tympany cow, the rumen puncture needle row, due to the large amount of bubbles and bubble chyme, inevitably clogging the discharge port, only a small amount of exhaust gases intermittently, pull out the needle when the cleaning again puncture deflated, not only deflation effect is still not ideal, but also create more cows pain and risk of infection; second, due to esophageal obstruction, esophageal spasm and paralysis and other diseases secondary to rumen tympany, and foaming tympany obstruction cardia case, the drugs can not stop leaven consumer guide or oral gavage, only perfused by the rumen puncture trocar, which led to puncture and deflate consumer guide infusion drugs can not be performed simultaneously, would delay the treatment of acute tympany cow time, will also affect the treatment results; third, even for pure gas tympany rumen, cows do not fit the general conduit or oral gavage drug infusion needle still need to eliminate lead drugs dead yeast, and conventional lancing only one pinhole needle (i.e., the discharge hole) used for perfusion, perfusion not only slow, and because it is a single point of infusion, or dead yeast eliminate lead drugs only huge stomach tumor 一处起作用(发生瘤胃臌气时,瘤胃壁紧绷,平滑肌自动运动性减弱,瘤胃内容物运转迟滞),无法有效发挥止酵消导作用,也无法使健胃药物充分发挥作用;第四,瘤胃臌气尤其是急性瘤胃臌气在穿刺放气时应有效控制放气速度,进行间歇式放气,以免快速放气后,腹腔压力迅速降低,胸腔负压升高,血液迅速回流,导致脑缺氧,而传统的穿刺针并无可以控制间歇性放气的装置。 A function (rumen tympany occurs, rumen wall tension, weakened muscle automatic movement, hysteresis operation of rumen contents), can not effectively function as a stopper fermentation eliminate lead action, the drug can not make full play stomach; Fourth , especially acute rumen tympany rumen tympany paracentesis should effectively control the air exhaust velocity, intermittent service deflated, in order to avoid the rapid deflation, abdominal pressure is rapidly reduced, the negative pressure increased the chest, rapid blood reflux, resulting in cerebral hypoxia, the conventional apparatus does not puncture needle intermittent deflation can be controlled.

[0008] 申请号为201420327559.0的专利公开的治疗瘤胃臌气的装置具有放气部和注药部,解决了放气和灌注药物不能同时进行的问题,但是,其技术方案虽在放气部增设了几个放气孔,对于泡沫性瘤胃臌气也只是能排除多个气泡的气体,依然容易被气泡中的食糜堵塞,其实际应用效果并不好;另外,其注药部同传统的穿刺针一样,只能在针头进行单点注射,而反刍动物瘤胃(尤其是牛)体积巨大,且臌气时瘤胃运动迟滞,单点注射药物效果不佳,发生药效缓慢,导致治疗效果不理想。 [0008] Application Number device for treating rumen tympany of 201420327559.0 Patent Publication has a discharge portion and injection portion, solves the problem of outgassing and drug infusion can not be performed simultaneously, however, that the technical solution, though the addition of the discharge portion several louvres, the foam for rumen tympany can exclude only a plurality of gas bubbles, the bubbles are still easily clogged in the chyme, its practical application effect is not good; Furthermore, portions thereof with traditional injection puncture Like needle, only a single point of injection needles, and in ruminants (especially cows) huge volume, and when tympany rumen retardation, poor single-point injection drug effects, efficacy occurs slowly, leading to unsatisfactory therapeutic effect .

[0020] 与现有技术相比,本发明的穿刺放气针因为同时具有放气部和注药部,可以在向瘤胃灌注止酵消导或强心健胃药物的同时进行放气;同时,由于调节管和弹性片的存在,使得穿刺放气针放气孔在进入瘤胃时不会被泡沫上的食糜所堵塞;进一步地,注药部可以在反刍动物瘤胃中展开,旋转注药,在机械打击消泡的同时,将灌注药物多点、大范围、全方位地施于瘤胃内,使得放气、消泡和药物灌注的效果均大大提升;另外,放气部设置有压感器(气压感受器),可以随时监测瘤胃内气压,以指导间歇性放气的节奏和速度。 [0020] Compared with the prior art, the puncture needle of the present invention deflated as having both the discharge portion and injection portion, can be deflated while the perfusion fermentation dissipation stopper guide rumen or stomach cardiotonic drugs; while Since the presence of the tube and adjustment of the elastic sheet, such that the puncture needle bleed louvers will not be clogged when the foam on the chyme into the rumen; further, the injection unit can be deployed in the rumen of ruminants, the rotation of injection, at the same time against mechanical defoaming, the multi-drug perfusion, wide, applied to the full range of the rumen, such gassing, perfusion and defoaming effects are greatly enhanced; Further, the discharge portion is provided with a pressure sensor (susceptor pressure), gas pressure can be monitored at any time in the rumen, to guide rhythm and tempo intermittent deflation. 注药部具有上中下三个支撑柱以及固定在支撑柱内侧的软管,这种组合结构是为了配合注药部物理打碎瘤胃内气泡而设计:只用软管注药,软管因其本身的柔性无法在牛腹中转动碎泡,只用硬管则注药部各个关节点的密封性无法保证。 Injection portion having upper and lower three support posts inside the hose is fixed to the support column, and this composite structure is to accommodate the bubble injection section in the rumen break up the physical design: injection hose only, because the hose itself can not rotate the flexible foam bovine belly pieces, each only rigid pipe joints sealing the injection portion of the drug can not be guaranteed. 本发明则有效解决了这个问题:药液只在软管中流动,密封性好,不会漏药,硬质支撑结构固定在软管外围,为软管提供附着骨架,使其能展平转动,大范围击打碎泡。 The present invention is an effective solution to this problem: liquid flow only in the hose, sealing, and will not leak drug, a rigid supporting structure is fixed to the periphery of the hose, the hose is attached to the skeleton to provide, to enable rotation of the flattened , a wide range of break blow bubbles. 由于穿刺放气针的针头尖锐,将放气针直接在瘤胃内展开极易划伤胃壁,而且不同体积和种类的反刍动物瘤胃对展开半径的要求也不同。 Since the puncture needle sharp needle deflation, the deflated expanded needle directly in the rumen easily scratch the stomach, and different volumes and types of deployment requirements for ruminants are also different radii. 本发明采用两次展开解决此问题,第一次展开为半展开状态,在此状态下,注药部底部并未展平,但是足够各个针头体分散开,然后在针头弹簧的拉动下内折,通过这种方式将针头隐藏,然后再进行第二次展开,第二次展开为全展开状态,在此状态下,注药部底部展平,由于注药孔开设在每个分管下部侧面,注药孔此时也是水平,由于药液从注药孔排出时对分管产生反作用力,各反作用力的合力能使注药部旋转,最佳状态是各反作用力均顺时针方向或均逆时针方向,合力最大。 The present invention is to expand the use of two resolve this problem, the first semi-expanded deployed state, in this state, the bottom of the medicine injection portion is not flattened, but sufficiently dispersed individual needle body, and then the needle is pulled off in the spring by this way, the needle is hidden, then a second expanded, fully-expanded to a second expanded state, in this state, medicine injection flattened bottom portion, since the injection hole is provided in the lower side of each charge, At this level of drug is injection hole, since the chemical liquid is discharged from the injection hole of the charge generating reaction, the reaction forces of each injection unit can rotate, is best for each reaction are both clockwise or counter-clockwise direction, maximum force. 通过调节注入药液的压力大小,可以控制注药部的旋转速度。 Injection pressure by adjusting the size of the drug solution can be controlled to the rotational speed of the injection unit. 通过旋转,注药部可以打碎一部分气泡,由于药液的旋转喷洒,喷洒面积大,药液(止酵消导药物或健胃强心药物)在瘤胃运动迟滞的情况下依旧可以迅速发挥作用。 By rotary injection unit can break a part of the bubble, due to the rotation of the spray liquid, spraying a large area, liquid (stop fermentation eliminate lead drugs or cardiotonic drugs stomach) may still play a role in the rapid rumen case retardation, . 本发明的放气部能有效防止气泡上黏着的食糜堵塞放气通道并能控制放气节奏,本发明采用调节管进行调节,调节管外壁贴着放气通道内壁,在每一个放气孔处设有弹性片,通过弹性片将放气孔密封,通过这种设计,放气通道在一般情况下是密封的,防止气泡上黏着的食糜进入放气孔,当注药部工作一段时间后,气泡消除殆尽,这时按下放气按钮,接通电磁铁回路,电磁铁将铁磁性块吸引下来,调节管下移,调节管上的弹性片也下移,让调节孔与放气孔对齐,进行放气,松开放气按钮,电磁铁回路断电,但是这时卡块已经卡住铁磁性块,装置持续放气。 The discharge portion of the present invention can effectively prevent the adhesion of gas bubbles chyme bleed passage clogging and deflated to control the rhythm, the present invention employs the adjusting tube is adjusted, the adjustment tube wall against the inner wall of the discharge gas passage in each of the discharge hole an elastic sheet, an elastic sheet by sealing the discharge hole, through this design, the air discharge passage is generally sealed to prevent the adhesion of air bubbles into the chyme bleed hole portion when the injection work for some time, the bubbles elimination exhausted, then press the deflation button to turn on the solenoid circuit, the electromagnet to attract the ferromagnetic blocks down, down regulating pipe, adjusting the elastic sheet but also on the down tube, so that the discharge hole is aligned adjusting holes, for deflated, open the gas release button, electromagnet de-energized circuit, but this time block jammed card ferromagnetic block, continuous gassing device. 由于持续快速放气容易使反刍动物继发其他疾病,要周期性放气,因此,按下的调节管还要能回弹,按下归位按钮时,能将卡块推离铁磁性块的行程路线,进而使铁磁性块在归位弹簧的作用下上移,调节管上的弹性片在回弹弹簧的帮助下也上移,调节孔与放气孔错开,放气通道再次密封。 Readily due to continuous rapid deflation ruminants secondary to other diseases, to periodically deflated, thus adjusting the pressing tube also can spring back, when the home button is pressed, can block the card away from the ferromagnetic block travel route, thereby enabling the ferromagnetic blocks move under the action of the return spring, the elastic regulating plate on the tube is also moved up with the help of the rebound spring, offset adjustment hole and the discharge hole, the air discharge passage resealed. 设置按钮控制放气通道开闭比使用手柄直接推送或拉回调节管的优势在于推动手柄时易发力不均进而将瘤胃臌气穿刺针倾斜,而针头已经在瘤胃内展开,如果倾斜幅度较大易戳到胃壁,而按钮控制则不需使用者发力,更容易控制。 When setting button bleed passage control the opening and closing of the direct push or pull back the advantage that the adjusting tube pushes the handle than the handle uneven force prone Further rumen tympany inclined needle, and the needle has been deployed in the rumen, if the inclination rate lower than large easily poked stomach, while the control button is a user without force, and easier to control.

[0021] 本发明还设有压感器,能使术者方便地知道瘤胃内气压,合理地安排放气次数和速度。 [0021] The present invention also has a pressure sensor, a surgeon can easily know the rumen pressure, and reasonable arrangements and deflation times speed.

[0022] 本发明具有可以兼顾注射消泡剂和放气,并在注射药物时能有效地机械打碎瘤胃内气泡,防止气泡上黏着的食糜堵塞放气通道,同时可以大面积、全方位地在瘤胃内灌注药物的优点,本发明还能通过电磁推压盒控制放气节奏、通过压感器监测瘤胃内气压,减轻术者工作强度的同时,还能够有效指导术者的放气节奏和速度。 [0022] The present invention may have both a defoaming agent injection and venting, and air bubbles can be effectively mechanically breaking the rumen during injection to prevent the adhesion of gas bubbles chyme bleed passage clogging, while a large area, full perfused medicament in the rumen of the advantages, the present invention can also control the rhythm deflated by an electromagnetic urging the cartridge, through the rumen pressure sensor monitoring pressure, reduce the intensity of work of the surgeon, it is also possible to effectively guide the rhythm deflation surgeon and speed.
