Description

[0001] AN ENEMA ADMINISTERING APPARATUS AND A METHOD OF MANUFACTURING A POUCH THEREFOR

[0002] TECHNICAE FIEED OF THE PRESENT INVENTION

[0003] The present invention relates to an enema administering apparatus, and a method of manufacturing a pouch therefor.

[0004] BACKGROUND OF THE PRESENT INVENTION

[0005] An enema administering apparatus is used for administering enema to a patient during constipation. Presently known enema administering apparatuses include a pouch which has an opening. The pouch is made of PVC (Polyvinyl chloride). The pouch is adapted to store a drug. A catheter tube is in fluid communication with the pouch through the opening.

[0006] During administration of enema, medical personnel inserts the catheter tube in the rectum of a patient. Thereafter, the medical personnel applies pressure by hand on the pouch so that the drug stored in the pouch gradually propagates towards the catheter tube and is administered to the patient through the catheter tube.

[0007] IN257 / MUM / 2014 discloses an apparatus to administer an enema comprising an enema bag, wherein the enema bag includes an opening, a delivery tube, an applicator nozzle, and a removable cap. The tube has two ends, wherein the one end is attached in the opening of the enema bag and on the other end applicator nozzle is attached; the said applicator nozzle is inserted into’ the patient’s rectum. However, this enema bag do not ensure complete emptying of enema fluid and do not have provisions on tube for confirmable insertion into’ the patient’s rectum.

[0008] CN2123319U discloses a disposable enema apparatus applied during the medical personnel enema, which comprises an enema barrel (bottle or bag) made of soft plastic, and an anus plug made of hard plastic and is connected with a catheter in the middle. This enema apparatus has multiple components which make it difficult to handle & keep intact during enema procedure.

[0009] CN2889310 discloses an enema apparatus which is a positive pressure soft plastic bag. A positive pressure soft plastic drug bag is provided with a liquid outlet connected to a drop bulb through an enema tube. The liquid outlet of the drop bulb is connected with the enema tube and a speed governor is locked on the enema tube. This enema apparatus have drop bulb assembly which make this apparatus more complicated and difficult to handle.

[0010] CN117942446 discloses an enema apparatus which has a pressurizing mechanism comprising a sliding seat, a connecting seat, a limiting shaft, a spring and a shaft seat, the shaft seat is rotationally connected with the pressing shaft, and the shaft seat is connected with the connecting seat through the spring. This mechanism makes this apparatus very complicated and not user friendly.

[0011] WO2018189761 discloses an insert for the packaging of pre-filled enemas and an enema equipped with the insert which ensures that the enema has the possibility of being used by the operator at any time, with a single maneuver. WO2018189761 does not particularly describe enema bag apparatus.

[0012] Administration of enema by known enema administering apparatuses have various drawbacks. One such drawback is that the drug stored in the pouch is wasted as the drug is unable to completely enter the catheter tube when pressure is applied by hand on the pouch by the medical personnel. Such wastage of the drug leads to administration of a lesser dosage to the patient which is undesirable. Another drawback is that a flow of the drug through the catheter tube is driven by gravity. Hence, regulation of flow of the drug through the catheter tube is not possible. Additionally, the material of the catheter tube is rigid, and the open end of the catheter tube has a sharp edge which may cause injury to the patient during insertion of the catheter tube in the rectum. This may also lead to uneasiness in the patient at the time of insertion of the catheter tube for enema administration.

[0013] Additionally, the pouch is manufactured by known processes such as extrusion, casting, or calendaring process. Such known processes for manufacturing the pouch are prone to drawbacks such as formation of pin holes, uneven thickness, lack of integrity in seal, and sticking of walls of the pouch due to frictional force. Therefore, in view of the above- mentioned problems, it is desirable to provide a solution that can overcome the above- mentioned problems and limitations.

[0057] Referring to the accompanying Fig. 1, an enema administering apparatus 100 is disclosed herein. The enema administering apparatus 100 includes a pouch 110 which has an opening 120. The pouch 110 stores a drug 150. A catheter tube 130 is in fluid communication with the pouch 110 through the opening 120. A flow regulator valve 140 is disposed on the catheter tube 130. The flow regulator valve 140 enables regulation of a flow of the drug 150 through the catheter tube 130 from the pouch 110. A pressure applicator 160 is disposed at an end that is distal to the opening 120. The pressure applicator 160 is used for applying pressure on the pouch 110 which enables to gradual propagation of the drug 150 through the opening 120.

[0058] The pouch 110 is made of multi-layered sheets laminated over each other. The multilayered sheets are double-layered sheets.

[0059] The catheter tube 130 is in fluid communication with the pouch 110 through a sleeve 170 which is removably fitted with the opening 120 of the pouch 110. The pressure applicator 160 is a roller 160-A. The pressure applicator 160 is rolled over the pouch 110 towards the opening O to gradually propagate the drug 150 through the opening O. In an embodiment, the pouch 110 may be made of materials such as but not limited to Polypropylene (PP), Polyvinyl Chloride (PVC), High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE).

[0060] In an embodiment, the catheter tube 130 may be made of materials such as but not limited to Polyvinyl Chloride (PVC), Siliconized Polyvinyl Chloride, and Silicon.

[0061] Referring to the accompanying Fig. 2, the catheter tube 130 has an open-end O which is sealed with an end cap 180. In a preferred embodiment of the present invention, the catheter tube 130 is made of soft siliconized PVC, including a rounded edge E.

[0062] Referring to the accompanying Fig. 3, as per an alternate embodiment of the present invention, the pressure applicator 160 is a slider 160-B. The pressure applicator 160 slides over the pouch 110 towards the opening O to gradually propagate the drug 150 through the opening O.

[0063] Referring to the accompanying Figs. 4, 5 and 6, a separate embodiment of the present invention has been disclosed herein. In this exemplary embodiment, the pouch 110, the catheter tube 130 and the flow regulator valve 140 have similar constructional and functional characteristics as the embodiments shown in the accompanying Figs. 1, 2 and 3.

[0064] Referring to the accompanying Figs. 4, 5, 6 and 7, the sleeve 170 is a threaded sleeve 175. The threaded sleeve 175 has a catheter receiving portion 175- A which is adapted to couple a catheter unit U with the pouch 110. Additionally, a catheter fastener 190 is adapted to be attached to the catheter 130. The catheter receiving portion 175-A is adapted to be coupled to the catheter fastener 190, thereby coupling the catheter 130 with the pouch 110. A flow regulator valve 140 is disposed on the catheter tube 130. The flow regulator valve 140 enables regulation of a flow of the drug 150 through the catheter tube 130 from the pouch 110. As per a preferred embodiment of the present invention, each of the catheter receiving portion 175-A and the catheter fastening portion 190- A includes interlocking threads 175-Al, 190-Al. The catheter fastener 190 is adapted to be rotated with respect to the threaded sleeve 175. The catheter receiving portion 175-A is interlocked with the catheter fastening portion 190-A via the interlocking threads 175-Al, 190-Al. The threaded sleeve 175 has a seal cover 200 adapted thereon. The seal cover 200 includes a seal 200-A which is adapted to cover a sleeve opening 200-B. The seal 200-A enables restriction of flow of the drug 150 to the catheter 130 from the pouch 110 and creates a tamper proof seal too. The catheter fastener 190 includes a piercing protrusion 190-B which is adapted to puncture the seal 200-A when the catheter fastener 190 is coupled with the threaded sleeve 175. The drug 150 flows from the pouch 110 to the catheter 130 after the seal 200-A is ruptured. As per alternate embodiments of the present invention, the catheter fastener 190 and the sleeve 170 can be coupled by means of snap fitting arrangements, luer lock threads, quick lock mechanisms, and / or any other known means which involves simultaneous actions or any other locking mechanism available to secure the catheter fastener 190 and the sleeve 170. Additionally, the enema administering device 100 includes the catheter unit U, such that the catheter unit U is detachable from the pouch 110. The drug 150 is filled in the pouch 110 through the opening 120. Thereafter, the threaded sleeve 175 is fixed in the opening 120 in the pouch 110. The seal 200-A is adapted on the sleeve opening 200-B of the threaded sleeve 175, to seal the sleeve opening 200-B. That way, leakage from the pouch 110 is avoided along with rendering the pouch 110 tamper proof.

[0065] The catheter fastener 190 is screwably fastened to the threaded sleeve 175, thereby covering the seal cover 200. Additionally, the catheter fastener 190, which has the piercing protrusion 190-B disposed therein, opens, or punctures the seal 200-A when the catheter unit U is screwably attached to the pouch 110. The catheter unit U which includes the catheter tube 130 can be sterilized by Ethylene Oxide (EtO) or Gamma radiation technologies, separately. This ensures that only the catheter unit U can be sterilized to prevent the any alteration or damage to the overall enema administering apparatus 100 due to contact with EtO or any other radiation. Also, a requirement of special grade materials for manufacturing the pouch 110 that may be suitable for sterilization, is eliminated. The catheter unit U is exposed only during the time of when medical personnel opens the catheter unit after wearing hand gloves, thereby ensuring that the opening O of the catheter tube 130, is not contaminated.

[0066] Referring to the accompanying Fig. 8, an enema administering apparatus 100 has been disclosed as per an alternate embodiment of the present invention. A flow regulator valve 140 is disposed on the catheter tube 130. The flow regulator valve 140 enables regulation of a flow of the drug 150 through the catheter tube 130 from the pouch 110. The pouch 110 has rounded corners 210 which enable emptying of the drug 150 completely from the pouch. Due to the rounded comers 210, the drug 150 does not accumulate at corners, such as the rounded comers 210 of the pouch 110. Therefore, the drug 150 is completely emptied from the pouch 110, when force is applied on the pouch 110. The catheter tube 130, in the present embodiment, is fixedly integrated with the sleeve 170. Hence, the enema administering apparatus 100 is a one-piece integrated apparatus 100, without separate components, as per embodiment of the present invention. Additionally, the catheter tube 130 is fixedly attached with the sleeve 170, so that the drug can be filled in the pouch 110 through the opening O of the catheter tube 130. Thereafter, the opening O is sealed by the end cap 180. Referring to the accompanying Fig. 9 and 10 along with the accompanying Figs. 1 to 8, a method 300 of manufacturing a pouch 110 for an enema administering apparatus 100 is disclosed herein.

[0067] The method 300 as disclosed herein includes at a step 310, calendaring a PVC film to form a calendared film of a predetermined thickness. At a step 320, embossing the calendared film with a predetermined textured pattern is performed for forming a textured film sheet X, Y. At a step 330, laminating at least two textured film sheets over each other is performed. Here, the predetermined textured pattern on each of the at least two textured film sheets are facing each other, which eventually enables formation of a non-friction film sheet. At a step 340, laminating the at least two non-friction film sheets in a die of a predetermined shape is performed. At a step 350, welding of the non-friction film sheets is performed for forming the pouch 110.

[0068] As per an embodiment of the present invention, the step 350 of welding is succeeded or followed by a step of disposing a pressure applicator 160 at an end distal to the opening 120 for applying pressure on the pouch 110 for propagating a drug 150 which is stored in the pouch 110, gradually through an opening 120 defined on the pouch 110. The step 350 of welding includes a further step of forming the opening 120 for introducing and storing the drug 150 in the pouch 110.

[0069] As per an embodiment of the present invention, the step of forming the opening 120 is followed by a step of welding a sleeve 170 in the opening 120 of the pouch 110. Here, a sleeve diameter of the sleeve 170 is larger than a catheter tube diameter of the catheter tube 130. In an alternate embodiment of the present invention, the threaded sleeve 175 is welded in the opening 120 of the pouch 110.

[0070] Furthermore, the step of welding the sleeve 170 is followed by a further step of fixing the catheter tube 130 inside the sleeve 170 with an adhesive. Since the sleeve diameter of the sleeve 170 is larger than a catheter tube diameter of the catheter tube 130, hence the catheter tube 130 is slidably insertable inside the sleeve 170, by hand. Thereafter, an adhesive, which may be any medical grade adhesive known in the art, is applied to fix the catheter tube 130 inside the sleeve 170.

[0071] With the method 300 disclosed herein, the pouch 110 is made of at least two textured film sheets X, Y which are laminated over each other to form a non-friction film sheet 400. Due to textured patterns embossed on the textured film sheets X, Y, slippage between the textured film sheets X, Y is avoided. At least two non-friction film sheets 400 are further laminated in a die having a shape of the pouch 110 or any pre-determined shape and welded together to form the pouch 110.

[0072] Referring to the accompanying Figs. 1 to 9, at the time of administering enema, the medical personnel first remove the end cap 180 and then inserts the catheter tube 130 in the rectum of the patient. The catheter tube 130 is made of soft siliconized PVC and includes the rounded edge E. Hence, the patient does not encounter discomfort during of insertion the catheter tube 130 in the patient’s rectum, which too is a technical advantage achieved by the invention disclosed herein. After the catheter tube 130 is sufficiently inserted in the patient’s rectum, the medical personnel opens the flow regulator valve 140. Advantageously, the flow regulator valve 140 is adjusted to ensure that a desired flow rate of the drug 150 is allowed.

[0073] Thereafter, the medical personnel applies pressure on the pouch 110 assisted by the pressure applicator 160 which ensures that the drug 150 stored in the pouch 110 gradually progresses towards the opening 120. A technical advantage of implementing the pressure applicator 160 in the present invention is that the drug 150 stored in the pouch 110 is completely emptied out of the pouch 110 during administration of enema to the patient, and there is no wastage of the drug 150 as experienced in the prior art.
