Description

Technical Field

[0001] The invention relates to a forming mould, in particular to a forming mould for a non-invasive ventilator pressure sore prevention and decompression pad of a medical care appliance. Background Art

[0002] At present, N-CPAP is the safest and most effective ventilation method for internal diseases such as respiratory, cardiovascular, and neurological departments, as well as first aid on site. Complications such as skin indentation and pulmonary barotrauma are prone to occur during the N-CPAP process, which can directly affect the treatment of lung diseases in children. Reducing skin indentation has been widely concerned in the clinic since the use of N-CPAP, but its incidence remains high, with various literature reports of about 20% to 60%. Factors that induce skin indentation include low birth weight infants, premature infants, inappropriate size of mechanical ventilation masks or nasal plugs, and inadequate skin care measures during treatment. N-CPAP children are prone to skin indentation. The "pig nose anti-pressure patch" is used to fit the skin at the tip of the nose, nasal septum, and nasolabial groove, and acts as a pressure pad to separate the nasal plug from the thin and tender skin of the child. The non-invasive ventilator is usually worn for 4-24 hours a day, and clinically it is commonly worn for 8-24 hours a day. Due to long-term wearing of the machine, the facial skin that is in long-term contact with the nasal mask is under pressure for a long time, which often leads to pressure sores on the face of the wearer. When ventilation lasts for more than 48 hours, the facial skin injury rate is as high as 70%. When compression lasts for a long time and infants have poor nutrition and facial edema, compression injury is more likely to occur. Most users of non-invasive ventilators in the respiratory department are infants and young children. Because infants and young children have thin and tender faces and less fat, the incidence of pressure sores is higher. In the clinical process, since silicone pads are mostly manually cut by nursing staff according to the nose conditions of the children to prevent pressure sores, the disadvantage is that each nursing staff cuts the size and style differently, or the patch cannot be used after cutting, and it cannot be unified, and it greatly wastes the nursing staff's time and efficiency. Summary of the invention

[0003] In view of the above situation, the present invention provides a non-invasive ventilator pressure sore prevention pressure relief pad forming mold, which can be pressed and formed at the nurse station or ward according to the use specifications by using hydrocolloid auxiliary materials. Not only can it form a universal unified shape, it also meets the use requirements and greatly improves the use efficiency.

[0004] The technical solution of the present invention is: a non-invasive ventilator pressure sore prevention and decompression pad forming mold, including a portal frame and a portable handle on one side; the bottom of the portal frame is connected to a lower mold seat, and the inner side of the portal frame is symmetrically provided with a slideway, which is installed and matched with the slider on the upper mold seat, and a reset tension spring is installed between the upper mold seat and the portal frame; the upper and lower mold seats are respectively equipped with upper and lower molds, and the upper and lower mold seats and the upper and lower molds are provided with relative displacement limiters and positioning top screws; the upper end of the upper mold seat is provided with a pressure device directly acted by the hand or an indirect pressure connecting rod device. Therefore, by applying pressure to the upper mold and combining it with the lower mold, the hydrocolloid auxiliary material is directly acted on to form a decompression pad.

[0005] In the present invention, the slideway is a dovetail groove-shaped or trapezoidal-shaped slideway; the corresponding slider is a dovetail-shaped or trapezoidal-shaped slide rail.

[0006] Furthermore, the sliding block is arranged on one side of the upper mold base, or in the middle of the upper mold base.

[0008] Furthermore, the pressure device includes a hinged connecting rod at the upper end of the upper mold base, which is hinged to the handle connecting rod and is hinged to the hinge ear on the door frame through the handle connecting rod.

[0009] In the present invention, the position limiting body comprises a combination of protrusions symmetrically arranged on the side end surfaces of the upper and lower mold seats and grooves symmetrically arranged and matched with the outer side end surfaces of the upper and lower molds.

[0010] In the present invention, the upper and lower mold bodies respectively have two mold surfaces of the same shape but different specifications.

[0011] In the present invention, at least one side of the top screw seat is provided with a positioning top screw, one end of which is round-headed, and is positioned by contacting the round-headed top screw with circular grooves on the upper and lower molds at the corresponding position of the top screw.

[0013] In the present invention, the pressure relief pad formed by the pressure of the upper and lower moulds is a pig nose type pressure relief pad.

[0014] The beneficial effects of the present invention are: through the specially designed non-invasive ventilator pressure sore prevention pressure relief pad forming mold, it is not limited by the scope of use, and the hydrocolloid auxiliary material can be used to press and form the pig nose pressure relief pad at the nurse station or ward according to the use specifications. Not only can it form a universal unified shape, it meets the use requirements of different infants and young children and greatly improves the use efficiency. It solves the problem that the traditional manual cutting specifications and shapes are not marked, which affects the use effect and low efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Specific embodiments of the present invention See Figures 1 to Fig.16The mold for forming a pressure sore prevention and decompression pad for a non-invasive ventilator shown in the figure comprises a portal frame 1 and an auxiliary portable handle 3 provided on one side. The auxiliary portable handle 3 is used to stabilize the mold by pressing it with the hand during operation, and is convenient to carry. A lower mold seat 16 (the lower mold seat 16 is a fixed lower mold seat) is connected to the bottom of the portal frame 1, and a slideway 2 is symmetrically provided on the inner side of the portal frame 1. The slideway 2 of this embodiment adopts a dovetail groove-shaped slideway. The slideway 2 is installed and matched with a slider 7 on an upper mold seat 6 (the upper mold seat 6 is a movable upper mold seat), and the slider 7 is also a dovetail-shaped slider. Pins 9 and hooks 4 correspondingly provided on the portal frame 1 are symmetrically provided on both sides of the upper mold seat 6, and a reset tension spring 5 is installed between the hook 4 on the portal frame 1 and the pin 9 on the upper mold seat 6. When not in use, the upper mold seat 6 moves upward under the action of the reset tension spring 5. In the present invention, an upper mold seat 6 and a lower mold seat 16 are respectively provided with an upper mold 12 and a lower mold 13. In order to facilitate the replacement of the upper mold 12 and the lower mold 13 on the upper mold seat 6 and the lower mold seat 16. A relative displacement limiter is provided between the upper mold seat 6 and the lower mold seat 16 and the upper mold 12 and the lower mold 13, and an upper handle 11 and a lower handle 14 are provided on the upper mold seat 6 and the lower mold seat 16 respectively. The limiter in this embodiment includes an upper protrusion 18 and a lower protrusion 20 symmetrically provided on the outer side of the side end surface of the upper mold seat 6 and the lower mold 16, and an upper groove 17 and a lower groove 19 symmetrically provided on the inner side end surface of the upper mold 12 and the lower mold 16. The main function of the upper groove 17, the lower groove 19 and the upper protrusion 18 and the lower protrusion 20 is to ensure the stability of the mold assembly and the accuracy of the upper and lower mold matching. Therefore, the upper mold 12 and the lower mold 13 are respectively moved in the upper groove 17 and the lower groove 19 on the inner side of the upper mold 12 and the lower mold 16 through the upper protrusion 18 and the lower protrusion 20 thereon for disassembly, assembly and replacement. A lower pressure device composed of a pressing handle 8 directly acted by the hand is provided at the upper end of the upper mold seat 6. In the present invention, screw holes (not marked in the figure) are symmetrically opened on the outer side of the upper mold seat 6 and the lower mold seat 16, and upper top screws 10 and lower top screws 15 are provided on the screw holes. One end of the upper top screw 19 and the lower top screw 15 is a round head body, and the round head bodies on the upper top screw 10 and the lower top screw 15 are respectively contacted and positioned with the circular grooves 22 provided on the corresponding parts of the outer side of the upper mold 12 and the lower mold 13. Avoid displacement of the upper mold 12 and the lower mold 13 relative to the upper mold seat 6 and the lower mold seat 16. When the pressure relief pad is formed, the operator applies downward pressure by pressing the handle 8, which acts on the upper mold base 6, and the upper mold 12 is displaced to contact and close the lower mold 13 on the lower mold base 16. Therefore, by applying pressure to the upper mold 12 and combining it with the lower mold 13, the hydrocolloid auxiliary material is directly formed into a pressure relief pad.The hydrocolloid auxiliary material is composed of 90% aqueous polyurethane, which has good elasticity and can keep the local skin moist. The covered area becomes a relatively closed environment, which can improve the oxygen ion tension on the skin surface, promote blood circulation, and effectively reduce the occurrence of nasal septum indentation.

[0017] In the above, the lower mold base 16 and the portal frame 1 are connected together by mechanical means.

[0018] In the above, the upper mold base 6 and the lower mold base 16 are an open body formed by three baffle surfaces arranged on the floor. The open end is an entrance for inserting the upper mold 12 and the lower mold 13.

[0019] In the above, the upper mold 12 has two double-sided molds A and B with the same shape but different specifications on its main body, and both the A and B double-sided molds have concave molding cavities.

[0020] In the above, the lower mold 13 body has two double-sided molds C and D with the same shape but different specifications, and both of the C and D double-sided molds are convex molding molds. In view of the fact that the lower mold 13 has two double-sided convex molding molds C and D with the same shape but different specifications, a sink groove 21 is opened on the floor of the lower mold base 16. When assembled with each other, the convex molding mold on the lower mold 13 is embedded in the sink groove 21, which solves the problem of mutual interference.

[0021] In the above, the slideway 2 can be a trapezoidal slideway in addition to the dovetail groove shape. Similarly, the corresponding slider 7 is a trapezoidal slider of the same shape.

[0022] See Fig.17 A reference diagram of the use state of the compressed decompression pad in FIG1 is given. During operation, the nursing staff places the hydrocolloid dressing plate 23 on the lower mold 13 and straightens it, then holds the auxiliary portable handle 3 with one hand, and puts the other hand on the pressing handle 8, and applies downward pressure. After the upper mold 12 and the lower mold 13 are molded together, the reset spring 5 thereon is in a stretched state, and a compressed decompression pad 24 of a certain specification can be obtained. In the present invention, the decompression pad formed by the upper and lower molds is a pig nose type decompression pad. After the compression is completed, the upper mold 12 moves upward and resets under the action of the reset spring 5. When changing the specification, the upper mold 12 and the lower mold 13 are turned over and installed in the upper and lower mold seats to complete the mold replacement.

[0023] See Fig.18Another embodiment different from FIG. 1 is given. It is based on the direct action of the hand in FIG. 1 and has been improved accordingly. The difference is that the pressing handle is removed, and a connecting rod 27 is hinged on both sides of the original boss 28 on the upper mold base 6, and is hingedly connected to a bent handle connecting rod 26 through the connecting rod 27, so that one end of the bent handle connecting rod 26 is hinged to the hinge ear 25 symmetrically arranged on the upper end of the door frame 1. The other parts are the same as FIG. 1.

[0024] See Fig.19 Given Fig.18 Schematic diagram of the upper and lower mold closing process. When the handle connecting rod 26 is held by hand and pressure is applied downward, the handle connecting rod 26 sequentially acts on the connecting rod 27, the upper mold base 6 and the upper mold 12 to move downward, so that the upper mold 12 and the lower mold 13 are closed. Its use effect is the same as that of the structure in Figure 1.

[0025] See Fig. 20 Given the Fig.18 An embodiment in which the upper and lower molds are arranged at different positions. Fig.18 The difference is that the upper mold base 6, the upper mold 13 and the lower mold base 16, the lower mold 13 are respectively installed in the middle of the portal frame 1. That is, the lower mold base 16 is fixed to the bottom of the middle of the portal frame 1, and the upper mold base 6 is installed in the slideway 2 of the portal frame 1 through the sliders 7 on both sides of the upper middle part. Fig.18 The same, that is, a connecting rod 27 is hinged on both sides of the boss 28 at the upper end of the upper mold base 6, and the connecting rod 27 is hinged with the handle connecting rod 26, and one end of the handle connecting rod 26 is hinged with the hinge ear 25 symmetrically arranged on the door frame 1. The working principle is the same as Fig.19 same.
