Description
本發明係關於一種鼻胃管,尤指一種具有可膨脹單元的鼻胃管及其可膨脹單元與製造方法。The present invention relates to a nasogastric tube, and more particularly to a nasogastric tube having an expandable unit, an expandable unit thereof, and a method of manufacturing the same.
當病患因昏迷、口頸部疾病、嚴重燒傷、癌末或因手術等各種原因而造成吞嚥困難、不能由口部進食或進食配合度不佳時,則需從鼻腔放置一條鼻胃管至病患的胃部,以灌食的方式協助病患進食或服藥。When the patient has difficulty swallowing due to various reasons such as coma, neck and neck disease, severe burns, cancer, or surgery, and cannot be fed by the mouth or the food is not well matched, a nasogastric tube should be placed from the nasal cavity. The stomach of the patient is assisted by the patient to eat or take the medicine by feeding.
請參考圖1A及圖1B,圖1A為習知的鼻胃管示意圖;圖1B為圖1A的鼻胃管於插入病患後的示意圖。鼻胃管4包含一中空管體43以及一灌食器接頭42,灌食器接頭42設置於中空管體43的近端41。於設置鼻胃管4時,以中空管體43的遠端44由病患P的鼻孔插入,在中空管體43的遠端44到達咽喉時需讓病患P配合同時做吞嚥動作或由吸管吸幾口水,讓中空管體43能夠順利的通過咽喉部經由食道進入胃部。然而,由於中空管體43為軟性材質,且食道A4開口相較於氣管A5開口狹窄,即便病患P配合做出吞嚥動作,當中空管體43的遠端44到達食道A4上方的會厭(epiglottis)時,醫護人員不易準確地控制中空管體43以將其遠端44順利地插入食道A4,有可能誤將鼻胃管4插入口腔O甚至是氣管A5造成病患嗆咳而導致吸入性肺炎。即,當中空管體43的遠端44與後咽壁A3的距離較遠時(如圖1B之虛線所示,遠端44與後咽壁A3之距離為D),鼻胃管4容易被誤插入病患口腔O或氣管A5);當中空管體43的遠端44與後咽壁A3的距離較近時(如圖1B之實線所示,遠端44與後咽壁A3之距離為D’),此時才能順利將鼻胃管4之遠端44插入病患之食道A4。因此,設置時需要將鼻胃管4之遠端44盡可能地靠近後咽壁A3,才能避免誤插。即便對有相當經驗的醫護人員而言,有時仍需要多次嘗試方能順利地將鼻胃管4設置好。若是設置困難,甚至需要使用額外的輔助器材(例如壓舌板或麥氏插管鉗,Magill intubating forceps)才能將鼻胃管4設置到病患P的胃部。以上種種過程,均會造成病患的不適感,更浪費許多醫療的時間成本。Please refer to FIG. 1A and FIG. 1B. FIG. 1A is a schematic view of a conventional nasogastric tube; FIG. 1B is a schematic view of the nasogastric tube of FIG. 1A after being inserted into a patient. The nasogastric tube 4 includes a hollow tubular body 43 and a feeder joint 42 that is disposed at the proximal end 41 of the hollow tubular body 43. When the nasogastric tube 4 is set, the distal end 44 of the hollow tubular body 43 is inserted by the nostril of the patient P, and when the distal end 44 of the hollow tubular body 43 reaches the throat, the patient P needs to cooperate with the swallowing action or A few mouthfuls of water are sucked by the straw, so that the hollow tube body 43 can smoothly enter the stomach through the esophagus through the throat. However, since the hollow tube body 43 is of a soft material and the opening of the esophagus A4 is narrower than the opening of the trachea A5, even if the patient P cooperates to make a swallowing action, when the distal end 44 of the hollow tube body 43 reaches the epiglottis above the esophagus A4 ( When epiglottis), it is difficult for the medical staff to accurately control the hollow tube body 43 to smoothly insert the distal end 44 into the esophagus A4. It is possible to accidentally insert the nasogastric tube 4 into the oral cavity O or even the trachea A5, causing the patient to cough and cause inhalation. Pneumonia. That is, when the distal end 44 of the hollow tubular body 43 is far from the posterior pharyngeal wall A3 (as indicated by the broken line in Fig. 1B, the distance between the distal end 44 and the posterior pharyngeal wall A3 is D), the nasogastric tube 4 is easily Misplaced into the patient's oral cavity O or trachea A5); when the distal end 44 of the hollow tubular body 43 is closer to the posterior pharyngeal wall A3 (as shown by the solid line in Fig. 1B, the distance between the distal end 44 and the posterior pharyngeal wall A3) For D'), the distal end 44 of the nasogastric tube 4 can be smoothly inserted into the esophagus A4 of the patient. Therefore, it is necessary to set the distal end 44 of the nasogastric tube 4 as close as possible to the posterior pharyngeal wall A3 in order to avoid mis-insertion. Even for a medical professional with considerable experience, sometimes it is necessary to try several times to successfully set the nasogastric tube 4. If it is difficult to set up, even need to use additional auxiliary equipment (such as tongue depressor or Magill intubating forceps) to set the nasogastric tube 4 to the stomach of the patient P. All of the above processes will cause discomfort to the patient and waste a lot of medical time costs.
因此,若能提出一種便於醫護人員順利設置的鼻胃管,可以讓醫護人員準確地將鼻胃管插入食道而順利地通過咽喉部。如此一來,除了能減輕病患於設置鼻胃管過程中的不適感,還可節省寶貴的醫療時間成本。Therefore, if a nasogastric tube is provided which is convenient for the medical staff to set up smoothly, the medical staff can accurately insert the nasogastric tube into the esophagus and smoothly pass through the throat. In this way, in addition to reducing the patient's discomfort during the setting of the nasogastric tube, valuable medical time costs can be saved.

After the cavity C is filled with a fluid (which may be a gas, a liquid or a semi-liquid), the expandable unit 122 can be expanded toward one side of the tubular body 1 and the tubular body 1 can be pressed down, so that the distal end E2 is lifted up and far away. The distance between the end and the posterior pharyngeal wall A3 is shortened or attached to the posterior pharyngeal wall A3 (as shown in Figure 2H) to guide the distal end E2 into an esophagus A4. Wherein the liquid can be a physiological saline solution; a semi-liquid such as a colloid, an emulsion or a solid-liquid mixture. The process in which the expandable unit 122 expands toward one side of the tubular body 1 and presses down the tubular body 1 will be described later.
進一步說,在本實施例中,可膨脹單元122係沿長軸方向DL設置於管狀本體1的第二管體12上,且設置於第二管體12之一側。並且第二管腔121連通有第二開口O2以及空腔C。亦即,如圖2A及圖2D所示,第二管體12在遠端E2的某一側有部份管壁設置可膨脹單元122。簡言之,本實施例中的可膨脹單元122係鄰設於遠端E2的末端位置,並設置於第二管體12上之一側。Further, in the present embodiment, the expandable unit 122 is disposed on the second tube body 12 of the tubular body 1 along the long axis direction DL and is disposed on one side of the second tube body 12.

It is in communication with the second lumen 121.
於實際應用時,醫護人員可將灌食器(圖未示)接上Y型接頭3的第一接口31,而將流體食物或藥物經由第一開口O1、第一管腔111及第三開口O3注入至病患的胃部。另一方面,第二接口32則是用於作為對可膨脹單元122充入流體或將充入之流體洩出或抽出之用。使用方式如後所述。In practical application, the medical staff can connect the filling device (not shown) to the first interface 31 of the Y-joint 3, and the fluid food or medicine through the first opening O1, the first lumen 111 and the third opening O3. Infused into the stomach of the patient. On the other hand, the second interface 32 is for use as a fluid for filling the expandable unit 122 or for venting or withdrawing the fluid to be filled. The usage is as described later.
在實際使用時,醫護人員同樣可利用Y型接頭3的第二接口32對第二管腔121充入流體,所充入的流體會經由第二開口O2充入第二管腔121,而讓流體進一步充入於空腔C中,使得可膨脹單元122向第二管體12的其中一側膨脹。In actual use, the medical staff can also use the second interface 32 of the Y-type connector 3 to fill the second lumen 121 with fluid, and the filled fluid is filled into the second lumen 121 via the second opening O2, and The fluid is further charged into the cavity C such that the expandable unit 122 expands toward one side of the second tubular body 12.
此外,當可膨脹單元122於臨近病患的下鼻甲A6末端前或通過下鼻甲A6前,如圖2D所示,當醫護人員尚未自Y型接頭3的第二接口32經由第二開口O2對第二管腔121連通的空腔C充入流體,故可膨脹單元122此時尚未膨脹。也就是說,當可膨脹單元122於鄰近病患的下鼻甲A6末端前或通過下鼻甲A6前,可膨脹單元122係為非膨脹狀態。In addition, when the expandable unit 122 is adjacent to the patient's lower turbinate A6 end or before the lower turbinate A6, as shown in FIG. 2D, when the medical staff has not yet passed from the second interface 32 of the Y-joint 3 via the second opening O2 The cavity C in which the second lumen 121 communicates is filled with fluid, so that the expandable unit 122 has not expanded at this time. That is, the expandable unit 122 is in a non-expanded state before the expandable unit 122 is adjacent to the patient's lower turbinate A6 end or past the inferior turbinate A6.
請參考圖2E及圖2F,圖中顯示可膨脹單元122的空腔C由於Y型接頭3的第二接口32對第二管腔121充入流體,此時可膨脹單元122將由於空腔C充入流體而朝外側擴張。請再參考圖2C中所示的箭頭,圖2C中的箭頭表示當可膨脹單元122膨脹時所產生的作用力,可膨脹單元122只向第二管體12的其中一側(如圖面所示的向上方向)膨脹,而可膨脹單元122因膨脹而產生向管狀本體1的作用力將施加於管狀本體1,也就是充入空腔C之流體將會造成對管狀本體1的壓力,並使管狀本體1受壓而抵於鼻咽部後上壁A2與軟顎Pt之間(顯示於圖2H);更確切地說,使管狀本體1受壓而抵於鼻咽部後上壁A2之下方到軟顎Pt之後側。此外,由於表面張力的因素,可膨脹單元122彎曲膨脹的表面與第二管體12所連接的邊緣處,將受到一向內及向上的分力,使得遠端E2往上抬升並縮短與後咽壁A3之距離或貼附於後咽壁A3上。亦即,如圖2G所示,當空腔C在充入流體後,由於管狀本體1本身剛性與可膨脹單元122表面張力的因素,將能使可膨脹單元122向管狀本體1之一側膨脹並下壓管狀本體1並將其抵於鼻咽部後上壁A2與軟顎Pt之間(鼻咽部後上壁A2之下方與軟顎Pt之後側),同時使得遠端E2自虛線所示的位置向上抬升至如實線所示的位置。藉此,遠端E2將向病患P的後咽壁A3靠近(縮短遠端E2與後咽壁A3之距離或是使遠端E2貼附於後咽壁A3),以引導遠端E2進入一食道A4。Referring to FIG. 2E and FIG. 2F, the cavity C of the expandable unit 122 is shown as the second lumen 32 of the Y-joint 3 is filled with fluid, and the expandable unit 122 will be due to the cavity C. Filled with fluid and expanded outward. Referring again to the arrow shown in FIG. 2C, the arrow in FIG. 2C indicates the force generated when the expandable unit 122 is inflated, and the expandable unit 122 is only directed to one side of the second tube 12 (as shown in the figure) The upward direction of the expansion is shown, and the force exerted on the tubular body 1 by the expandable unit 122 due to expansion will be applied to the tubular body 1, that is, the fluid filled into the cavity C will cause pressure on the tubular body 1, and The tubular body 1 is pressed against the nasopharynx posterior wall A2 and the soft palate Pt (shown in Figure 2H); more specifically, the tubular body 1 is pressed against the nasopharynx posterior wall A2 Below the soft 颚Pt rear side. In addition, due to the surface tension factor, the curved and expanded surface of the expandable unit 122 and the edge to which the second tubular body 12 is connected will be subjected to an inward and upward component force, so that the distal end E2 is lifted upward and shortened with the posterior pharynx. The distance of the wall A3 is attached to the posterior pharyngeal wall A3. That is, as shown in FIG. 2G, when the cavity C is filled with the fluid, the expandable unit 122 can be inflated toward one side of the tubular body 1 due to the rigidity of the tubular body 1 itself and the surface tension of the expandable unit 122. Pressing the tubular body 1 and pressing it between the anterior wall A2 and the soft palate Pt (below the posterior superior wall A2 of the nasopharynx and the posterior side of the soft palate Pt), while making the distal end E2 as shown by the dashed line The position is raised up to the position shown by the solid line. Thereby, the distal end E2 will approach the posterior pharyngeal wall A3 of the patient P (shortening the distance between the distal end E2 and the posterior pharyngeal wall A3 or attaching the distal end E2 to the posterior pharyngeal wall A3) to guide the distal end E2 into One esophagus A4.
請再參考圖2G及圖2H,以進一步說明鼻胃管2的使用方式。如圖2G所示,在將鼻胃管2置入病患P時,醫護人員會將鼻胃管2之遠端E2插入於病患P之鼻孔,接著遠端E2依序通過下鼻道通道N6而進入到鼻咽部(nasopharynx)A1。此時,醫護人員可由管狀本體1上設置的標誌M的位置(例如已經看見標誌M已經位於病患P的鼻孔處)得知可膨脹單元122已鄰近下鼻甲A6末端或通過下鼻甲A6。當可膨脹單元122鄰近於下鼻甲A6末端或通過下鼻甲A6後,而遠端E2此時係位於食道A4上方的口咽部(oropharynx),此時醫護人員可自Y型接頭3的第二接口32充入流體,所充入的流體會經由第二開口O2充入第二管腔121並進入空腔C,使可膨脹單元122沿著管狀本體1的徑向其中一側膨脹。Please refer to FIG. 2G and FIG. 2H again to further illustrate the manner of use of the nasogastric tube 2. As shown in Fig. 2G, when the nasogastric tube 2 is placed in the patient P, the medical staff inserts the distal end E2 of the nasogastric tube 2 into the nostril of the patient P, and then the distal E2 sequentially passes through the lower nasal passage. N6 enters the nasopharyngeal (nasopharynx) A1. At this point, the healthcare professional can know from the position of the marker M provided on the tubular body 1 (eg, the marker M has been seen at the nostril of the patient P) that the expandable unit 122 has been adjacent to the end of the lower turbinate A6 or through the inferior turbinate A6. When the expandable unit 122 is adjacent to the end of the lower turbinate A6 or through the lower turbinate A6, and the distal end E2 is now located in the oropharynx above the esophagus A4, the medical staff can be the second from the Y-joint 3 The interface 32 is filled with fluid, and the charged fluid is charged into the second lumen 121 through the second opening O2 and into the cavity C, causing the expandable unit 122 to expand along one side of the radial direction of the tubular body 1.
接著,如圖2H所示,醫護人員繼續充入流體至空腔C以使可膨脹單元122持續膨脹;可膨脹單元122在膨脹狀態下,其朝向管狀本體1的其中之一個徑向方向(如圖2F中所示的頂部)的膨脹幅度相較其他方向更為明顯突出。同時,醫護人員繼續插入管狀本體1,將使可膨脹單元122一邊膨脹並一邊往病患咽喉部前進,進而使可膨脹單元122抵頂病患P的鼻咽部後上壁(choanae)A2。此時,可膨脹單元122無法往鼻咽部後上壁A2方向繼續膨脹。但因持續充入的流體會讓可膨脹單元122內部的壓力持續增加,因此可膨脹單元122會向鼻咽部後上壁A2下方的方向造成對管狀本體1的壓力而下壓管狀本體1,並將管狀本體1抵於鼻咽部後上壁A2與軟顎(soft palate)Pt之間(鼻咽部後上壁A2之下方與軟顎Pt之後側),且由於管狀本體1本身剛性的因素以及鼻咽部後上壁A2下方與軟顎Pt之後側對該區域的管狀本體1所提供之反作用力配合前述可膨脹單元122彎曲膨脹的表面與第二管體12所連接的邊緣處所受到的向內及向上的分力,將共同使得遠端E2向後咽壁接近甚至貼附於後咽壁A3。藉此,遠端E2將沿著病患P的後咽壁A3而進入食道A4。因此,透過此方式即可讓管狀本體1的遠端E2與後咽壁A3之距離縮短或貼附後咽壁A3,而提高鼻胃管遠端E2進入食道A4的機率,而降低遠端E2進入到病患P的氣管A5或口腔O的機率。Next, as shown in FIG. 2H, the medical staff continues to fill the fluid to the cavity C to continue to expand the expandable unit 122; the expandable unit 122 is in the expanded state, which faces the radial direction of the tubular body 1 (eg, The width of the top portion shown in Figure 2F is more pronounced than the other directions. At the same time, the medical staff continues to insert the tubular body 1 so that the expandable unit 122 expands and advances toward the throat of the patient, thereby causing the expandable unit 122 to abut the choanae A2 of the nasopharynx of the patient P. At this time, the expandable unit 122 cannot continue to expand toward the posterior wall A2 of the nasopharynx. However, since the continuously filled fluid causes the pressure inside the expandable unit 122 to continuously increase, the expandable unit 122 causes the tubular body 1 to be pressed against the pressure of the tubular body 1 in the direction below the posterior superior wall A2 of the nasopharynx. And the tubular body 1 is abutted between the posterior wall A2 of the nasopharynx and the soft palate Pt (below the posterior superior wall A2 of the nasopharynx and the posterior side of the soft palate Pt), and since the tubular body 1 itself is rigid The factor and the reaction force provided by the tubular body 1 of the region behind the nasopharynx posterior superior wall A2 and the soft palate Pt are matched with the curved expansion surface of the expandable unit 122 and the edge connected to the second tubular body 12 The inward and upward component forces will collectively cause the distal end E2 to approach or even attach to the posterior pharyngeal wall A3. Thereby, the distal end E2 will enter the esophagus A4 along the posterior pharyngeal wall A3 of the patient P. Therefore, in this way, the distance between the distal end E2 of the tubular body 1 and the posterior pharyngeal wall A3 can be shortened or attached to the posterior pharyngeal wall A3, and the probability of the distal end of the nasogastric tube E2 entering the esophagus A4 is increased, and the distal end E2 is lowered. The probability of entering the trachea A5 or oral O of the patient P.
此外,當遠端E2靠近病患P的後咽壁A3且順利往下通過口咽部或進入食道A4後,醫護人員即可藉由Y型接頭3的第二接口32,將第二管腔121內所充入的流體洩出或抽出,而使已經膨脹之可膨脹單元122收縮,而管狀本體1可以再繼續向下深入食道A4。In addition, when the distal end E2 is close to the posterior pharyngeal wall A3 of the patient P and smoothly passes through the oropharynx or into the esophagus A4, the medical staff can pass the second lumen 32 of the Y-joint 3 to the second lumen. The fluid filled in 121 is vented or withdrawn, and the expanded expandable unit 122 is contracted, and the tubular body 1 can continue down to the esophagus A4.
當遠端E2被設置於病患P的胃部後,醫護人員即可透過Y型接頭3的第一接口31經由第一開口O1及第一管腔111注入流質的食物或藥物至病患P的胃部,或從中進行引流動作等。After the distal end E2 is set in the stomach of the patient P, the medical staff can inject the liquid food or medicine into the patient P through the first opening O1 and the first lumen 111 through the first interface 31 of the Y-joint 3 The stomach, or the drainage action from it.
本發明亦提供另一較佳實施例,亦為一種鼻胃管。請參考圖3A至圖3E,圖3A為本發明另一較佳實施例的鼻胃管示意圖。圖3B為圖3A的鼻胃管沿D-D剖面線的示意圖。圖3C為圖3A的鼻胃管沿E-E剖面線的示意圖。圖3D為圖3A的鼻胃管可膨脹單元膨脹時的局部示意圖。圖3E為圖3D的鼻胃管沿G-G剖面線的示意圖。The present invention also provides another preferred embodiment, which is also a nasogastric tube. Please refer to FIG. 3A to FIG. 3E. FIG. 3A is a schematic view of a nasogastric tube according to another preferred embodiment of the present invention. Figure 3B is a schematic illustration of the nasogastric tube of Figure 3A taken along line D-D. Figure 3C is a schematic illustration of the nasogastric tube of Figure 3A taken along the E-E section line. Figure 3D is a partial schematic view of the nasogastric tube expandable unit of Figure 3A as it expands. 3E is a schematic view of the nasogastric tube of FIG. 3D along the G-G section line.
圖3A中,鼻胃管2a與前一實施例的鼻胃管2具有大致相同的元件及元件連結關係。不過,在本實施例中鼻胃管2a的管狀本體1a與鼻胃管2的管狀本體1具有部分不同的結構。不同之處在於,管狀本體1a的第二管體12係套設於第一管體11外,因此,第一管體11被第二管體12所包覆,而形成一種同軸管路(co-axial)或是管中管的雙腔態樣。第一管體11具有一第一管腔111,第二管體12與第一管體11對應設置,第二管體12則具有一第二管腔121,而且,可膨脹單元122設置於第二管體12。除此之外,本實施例中的可膨脹單元122同樣是設置於第二管體12之一側。另外,可膨脹單元122的前後兩端則分別藉由一連接件F,將其束縛住或固定於第二管體12上,而不會在使用鼻胃管2過程中鬆脫或飛脫。In Fig. 3A, the nasogastric tube 2a has substantially the same element and element connection relationship as the nasogastric tube 2 of the previous embodiment. However, in the present embodiment, the tubular body 1a of the nasogastric tube 2a has a partially different structure from the tubular body 1 of the nasogastric tube 2. The difference is that the second tube body 12 of the tubular body 1a is sleeved outside the first tube body 11. Therefore, the first tube body 11 is covered by the second tube body 12 to form a coaxial tube (co -axial) or the dual cavity pattern of the tube in the tube. The first tube body 11 has a first lumen 111, the second tube body 12 is disposed corresponding to the first tube body 11, the second tube body 12 has a second tube chamber 121, and the expandable unit 122 is disposed at the first portion Two tube body 12. In addition, the expandable unit 122 in this embodiment is also disposed on one side of the second tubular body 12. In addition, the front and rear ends of the expandable unit 122 are respectively tied or fixed to the second tube 12 by a connecting member F, without loosening or flying off during the use of the nasogastric tube 2.
請同時參考圖3B,可膨脹單元122係設置於第二管體12的部分管壁上。在本實施例中,由於第一管體11與第二管體12是同軸管路或管中管的雙腔結構,因此管狀本體1a的徑向剖面亦呈現第二管腔121圍繞第一管腔111的同心圓狀,而第二管體12的管壁上的某一側有部份設置可膨脹單元122,如圖3C所示。Referring to FIG. 3B at the same time, the expandable unit 122 is disposed on a portion of the pipe wall of the second pipe body 12. In this embodiment, since the first tube body 11 and the second tube body 12 are a double-cavity structure of a coaxial tube or a tube-in-tube tube, the radial cross-section of the tubular body 1a also presents a second lumen 121 surrounding the first tube. The cavity 111 is concentrically shaped, and a certain side of the tube wall of the second tube 12 is partially provided with an expandable unit 122, as shown in Fig. 3C.
請同時參考圖2G、圖3D及圖3E。當管狀本體1a的可膨脹單元122鄰近於下鼻甲A6末端或通過下鼻甲A6後,醫護人員同樣可利用Y型接頭的第二接口(圖未示)對第二管腔121充入流體,所充入的流體會經由第二開口O2充入第二管腔121的空腔C,使可膨脹單元122向第二管體12的其中一側膨脹。此時,可膨脹單元122亦因膨脹而抵頂鼻咽部後上壁A2及/或下鼻甲A6末端,並且遠端E2的末端將向上抬升朝著後咽壁A3接近,而使前方的遠端E2與後咽壁A3之距離縮短或貼附後咽壁A3。進而讓整個管狀本體1a同樣可順利地沿病患P的後咽壁A3伸入於食道A4,直到設置於病患P的胃部。Please refer to FIG. 2G, FIG. 3D and FIG. 3E at the same time. When the expandable unit 122 of the tubular body 1a is adjacent to the end of the lower turbinate A6 or passes through the lower turbinate A6, the medical staff can also use the second interface (not shown) of the Y-joint to fill the second lumen 121 with fluid. The filled fluid is filled into the cavity C of the second lumen 121 via the second opening O2, causing the expandable unit 122 to expand toward one side of the second tubular body 12. At this time, the expandable unit 122 also swells against the end of the posterior nasopharynx A2 and/or the lower turbinate A6, and the distal end of the distal end E2 is lifted upward toward the posterior pharyngeal wall A3, and the front is far The distance between the end E2 and the posterior pharyngeal wall A3 is shortened or attached to the posterior pharyngeal wall A3. Further, the entire tubular body 1a can also smoothly extend into the esophagus A4 along the posterior pharyngeal wall A3 of the patient P until it is placed in the stomach of the patient P.
此外,鼻胃管2a的其他技術特徵可參考本發明上述較佳實施例的鼻胃管2,於此不再贅述。In addition, other technical features of the nasogastric tube 2a can be referred to the nasogastric tube 2 of the above preferred embodiment of the present invention, and details are not described herein again.

The tubular body has a long axis direction and includes a proximal end and a distal end, wherein the distal end is at a distance from the pharyngeal wall behind the nasogastric portion. Wherein, the expandable unit is fixed on the tubular body along the long axis direction and adjacent to the distal end. The expandable unit has a cavity, and a fluid filled in the cavity expands the expandable unit toward one side of the tubular body and presses the tubular body downward, so that the distal end is lifted upward and the distance between the distal end and the posterior pharyngeal wall is shortened to guide The distal end enters the esophagus. In addition, the connection relationship between the components of the various components of the expandable unit, the changing manners, and the other components are the same as those described in the previous embodiments, and details are not described herein again.

Please refer to FIG. 4, which is a flow chart of steps of a method for setting a nasogastric tube according to still another preferred embodiment of the present invention. Figure 4 illustrates how the nasogastric tube of the present invention can be placed in the stomach of a patient, and the nasogastric tube comprises a tubular body and an expandable unit. The tubular body has a long axis direction and includes a proximal end and a distal end. The expandable unit is fixed to the tubular body along the long axis direction and adjacent to the distal end. The expandable unit has a cavity. For the other structures of the nasogastric tube and the connection relationship of the components used in the present embodiment, reference may be made to the above preferred embodiments, and details are not described herein again.
設置方法步驟如下,首先,須先將鼻胃管之遠端插入於病患的鼻咽部(步驟S01),接著,當可膨脹單元鄰近病患之一下鼻甲末端或通過病患之下鼻甲後,充入一流體至空腔,藉此使可膨脹單元向管狀本體之一側膨脹而下壓管狀本體,以使遠端向上抬升並使遠端與病患之後咽壁之距離縮短(步驟S02),最後,引導鼻胃管之遠端進入病患之一食道(步驟S03)。透過上述的三個步驟或設置方法,即可順利地完成將鼻胃管設置於病患胃部。The setting method steps are as follows. First, the distal end of the nasogastric tube must be inserted into the nasopharynx of the patient (step S01), and then, when the expandable unit is adjacent to one of the patient's inferior turbinate or after the patient's turbinate Filling a fluid into the cavity, thereby expanding the expandable unit toward one side of the tubular body and pressing the tubular body downward so that the distal end is lifted upward and the distance between the distal end and the patient's pharyngeal wall is shortened (step S02) Finally, the distal end of the nasogastric tube is guided into one of the esophagus of the patient (step S03). Through the above three steps or setting methods, the nasogastric tube can be smoothly placed on the stomach of the patient.
此外步驟S03中,在引導鼻胃管之遠端進入病患之一食道的步驟前更包含一步驟:使流體經由第二管腔並自第二接口洩出而使膨脹之可膨脹單元收縮。In addition, in step S03, before the step of guiding the distal end of the nasogastric tube into the esophagus of the patient, the method further comprises the step of causing the fluid to contract through the second lumen and expelling from the second interface to expand the expandable expandable unit.
此外,鼻胃管設置方法的其他技術特徵可參考本發明前些實施例的相關說明,於此不再贅述。In addition, other technical features of the method for setting the nasogastric tube can be referred to the related description of the previous embodiments of the present invention, and details are not described herein again.
綜上所述,依據本發明提供的一種鼻胃管及其可膨脹單元與製造方法,由於鼻胃管具有固定於管狀本體並鄰近遠端的可膨脹單元,且可膨脹單元具有一空腔,充入空腔之一流體使可膨脹單元向管狀本體之一側膨脹並下壓管狀本體,使遠端向上抬升並使遠端與後咽壁之距離縮短,藉此管狀本體的遠端將被引導而進入病患的食道。如此一來,醫護人員將可簡單地將鼻胃管順利地通過咽喉部使其插入食道而設置於胃部,降低設置失敗的機率。如此一來,除了能增加醫療從業人員設置鼻胃管的控制感和信心,減輕病患對於設置鼻胃管的反感或恐懼,還可節省寶貴的醫療時間成本。In summary, according to the present invention, a nasogastric tube and an expandable unit thereof and a manufacturing method thereof, since the nasogastric tube has an expandable unit fixed to the tubular body and adjacent to the distal end, and the expandable unit has a cavity, the charge One of the fluids entering the cavity expands the expandable unit toward one side of the tubular body and presses down the tubular body, causing the distal end to rise upwardly and shortening the distance between the distal end and the posterior pharyngeal wall, whereby the distal end of the tubular body will be guided And enter the patient's esophagus. In this way, the medical staff can simply put the nasogastric tube through the throat to insert it into the esophagus and set it on the stomach, reducing the probability of setting failure. In this way, in addition to increasing the sense of control and confidence of the medical practitioners to set the nasogastric tube, reducing the patient's resentment or fear of setting the nasogastric tube can also save valuable medical time costs.
