Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing technology, specifically to a device for feeding liquid food to patients. Background Technology
[0002] In modern medicine, especially in gastroenterology, feeding care for patients is crucial. Gastroenterology patients often suffer from varying degrees of digestive dysfunction, such as gastric ulcers, gastritis, post-esophageal surgery, and insufficient gastrointestinal motility, making it impossible for them to eat solid foods normally. Liquid diets become the main way for these patients to obtain nutrition.
[0003] The commercially available liquid diets and those prepared by families according to doctor's orders and delivered to hospitals vary significantly in terms of processing techniques and refinement. They commonly contain insufficiently crushed food particles, undissolved medication residue, or small clumps formed due to prolonged storage. When fed using traditional tools like syringes, these hidden impurities can easily flow into the patient's mouth. This residue may scratch and irritate the already delicate oral mucosa and throat, causing pain, discomfort, and even minor wounds, increasing the risk of infection. Furthermore, filtering the liquid diet is necessary. Traditional filters are mostly flat, and during filtration, residue easily accumulates on the surface. As feeding continues, this accumulation increases, not only hindering the smooth passage of the liquid diet but also clogging the filter, significantly reducing filtration efficiency and even forcing the entire feeding process to stop. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a patient liquid food feeding and nursing device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A patient liquid food feeding and nursing device includes a feeding tube, a push rod that passes through the feeding tube and is slidably disposed in the feeding tube by a piston block at its end, and a filter cover sleeved on the feeding tube's outlet end.
[0007] The feeding tube has a tapered discharge port at one end, and a flow guide shroud aligned with the discharge port is provided in the filter shroud.
[0008] The filter cover has an inwardly bent annular support portion on its inner side, and an annular collection groove is formed between the support portion and the filter cover.
[0009] The flow guide hood has a raised arc-shaped surface on the side facing the discharge port, and a frustum-shaped filter section is provided between the flow guide hood and the support section. The filter section consists of a support frame and a filter screen that are spaced apart. The filter section filters the material flowing above and guides the remaining material after filtration to the collection tank.
[0010] Preferably, the end of the support portion is bent inward, and a tapered guide port is provided on the inner side of the support portion.
[0011] Preferably, the side of the feeding tube near the discharge end is provided with a threaded band, and the filter cover is connected to the threaded band through a threaded structure.
[0012] Preferably, a sealing seat is threadedly installed on the end of the feeding tube away from the discharge end, and the push rod passes through the sealing seat; a push plate is provided at the end of the push rod, and pressing plates are provided on both sides of the sealing seat.
[0013] Preferably, the feeding tube has an observation window on its side, and a transparent glass block is embedded in the observation window.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The squeezed liquid food is filtered through a filter screen to effectively intercept food particles, drug residues and clumps in the liquid food, preventing the residue from scraping and irritating the patient's delicate oral mucosa and throat, reducing the risk of infection and alleviating the patient's pain and discomfort;
[0016] 2. The filter screen and support frame together form a frustum-shaped structure, which prevents residue from accumulating on the filter screen after filtration, keeps the filter screen unobstructed, avoids feeding interruptions due to filter screen blockage, saves feeding time, and reduces the workload of caregivers.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] Example
[0025] like Figure 1 As shown, a patient liquid food feeding and nursing device includes a feeding tube 1, a push rod 4 that passes through the feeding tube 1 and is slidably disposed in the feeding tube 1 through a piston block at its end, and a filter cover 2 sleeved on the feeding tube 1 at the discharge end.
[0026] A sealing seat 3 is threaded onto the end of the feeding tube 1 furthest from the outlet, and a push rod 4 passes through the sealing seat 3. This threaded installation ensures a tight connection between the sealing seat 3 and the feeding tube 1. A push plate 41 is provided at the end of the push rod 4, allowing caregivers to easily apply force to push the push rod 4 and smoothly expel the liquid food. Pressing pads 31 are provided on both sides of the sealing seat 3, providing a point of force for caregivers to press the push plate 41, making it easier to press the push plate 41. The sealing seat 3 is removable, facilitating the addition of liquid food to the feeding tube 1 and the removal of the push rod 4 for replacement or cleaning.
[0027] Please see Figure 3 , Figure 4 The main purpose of the filter cover 2 is to filter the liquid food squeezed out of the feeding tube 1. An annular support portion 21 is formed by bending inwards on the inner side of the filter cover 2. This support portion 21 not only provides stable support for the filter section, but also forms an annular collection groove of a certain depth between it and the filter cover 2. This collection groove provides space for subsequently filtered residue, thereby preventing residue from accumulating on the filter section and clogging the filter screen 24, ensuring that residue does not re-mix into the liquid food and endanger the patient's health.
[0028] Inside the filter hood 2, there is a flow guide hood 22 that is aligned with the outlet 12 of the feeding tube 1. The side of the flow guide hood 22 facing the outlet 12 is designed as a raised arc-shaped surface. This unique design allows the liquid food squeezed out from the outlet 12 to be evenly dispersed along the arc-shaped surface of the flow guide hood 22, avoiding the liquid food from concentrating and impacting the filter section, causing local blockage or insufficient filtration.
[0029] The frustum-shaped filter section, located between the flow guide hood 22 and the support section 21, is the core area of the entire filtration process. The filter section consists of spaced-apart support frames 23 and filter screens 24. The support frames 23 provide a robust structural support for the filter screens 24, ensuring that they will not deform or be damaged under the impact of the liquid. When the liquid flows down from the arc-shaped surface of the flow guide hood 22 and passes through the filter section, the filter screens 24, with their mesh structure, filter out food particles, drug residues, and clumps from the liquid, achieving efficient filtration of the upper flowing material. Simultaneously, due to the overall frustum-shaped flow guide design of the filter section, any remaining material after filtration flows along the frustum-shaped inclined surface of the filter section to the collection tank below, preventing residue from accumulating on the filter screens 24 and causing clogging.
[0030] The end of the support part 21 is bent inward, and a conical guide port 25 is provided on the inner side of the support part 21. It has the same function as the discharge port 12, which allows liquid food to flow out in a concentrated manner, making it convenient to feed the patient.
[0031] The filter cover 2 is connected to the feeding tube 1 using a convenient and stable threaded structure. Specifically, the feeding tube 1 has a threaded band 13 on its side near the discharge end. The filter cover 2 is screwed onto the threaded band 13 through a matching threaded structure. This connection method makes it easy for caregivers to install and remove the filter cover 2. Whether it is daily cleaning or replacement of parts, it can be completed efficiently, ensuring the hygiene and continuous availability of the device.
[0032] Please see Figure 2 The feeding tube 1 has an observation window 11 on its side, which contains a transparent glass block. This design allows caregivers to observe the flow of liquid food in real time during feeding, including the amount of liquid food remaining, the presence of air bubbles or abnormal impurities, etc. Through the intuitive feedback of the transparent window, caregivers can adjust the feeding speed in a timely manner, handle potential problems, and further improve the safety and accuracy of feeding.
[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
